Patients and Methods: One hundred and ten parturients of American Society of Anesthesiologists' I and II scheduled for cesarean section under spinal anesthesia were randomized into two groups. Group A (n = 55) received 5 IU IV bolus of oxytocin and Group B (n = 55) received 10 IU IV bolus of oxytocin after delivery. Ten milliliters per kilogram of 0.9% saline was administered to both groups as volume preload. Subarachnoid block was performed with size 24G spinal needles at L2/L3 or L3/L4 intervertebral space with the patients in sitting position. Two milliliters of 0.5% heavy bupivacaine was administered slowly intrathecally. Following delivery of the baby, IV boluses of 5 IU (Group A) or 10 IU (Group B) of oxytocin were administered slowly, and recording of heart rate, systolic, diastolic, and mean arterial blood pressure was done every minute for 5 min after bolus injection. IV infusion of 30 IU of oxytocin in 500 ml of 0.9% saline (60 mU/ml) at a rate of 125 ml/h was continued in both groups till the end of surgery. Estimated blood loss (EBL) was assessed by visual estimation. Patients were monitored continuously until 24 h after surgery to evaluate PDPH and PONV. Results: There were no statistically significant differences in the EBL between the two groups. There was no significant rise in heart rate and no significant decrease in mean arterial blood pressure in Group A compared to Group B. The incidence of PDPH and PONV was also comparable in both groups. Conclusion: Five IU of IV bolus of oxytocin is as effective as 10 IU of IV bolus in reducing blood loss during cesarean section.

Though many modalities for pain management exist, there is the need to investigate safer and affordable regimens that will provide adequate analgesia with minimal side effects and with ease of administration. Alternating doses of intramuscular acetaminophen and intramuscular pentazocine was studied as an alternative to provide safe and effective post-caesarean section analgesia. Its effectiveness and side effect profile in our environment have not been previously investigated. AIMS AND OBJECTIVES The study aimed to compare the analgesic and side effect profile of intramuscular pentazocine with another regimen involving alternating doses of pentazocine and acetaminophen within the first 48hours after surgery. DESIGN OF THE STUDY This was a prospective, comparative and randomized study among 142 women who voluntarily consented to the study and had elective caesarean section from May 2014 to May 2015 at the Ahmadu Bello University Teaching Hospital, Zaria. Setting: The Study was conducted at the obstetrics and gynecology department of the teaching hospital of Ahmadu Bello University, Zaria. MATERIALS AND METHODS Consecutive eligible pregnant women who were slated for elective caesarean section were recruited at the antenatal clinic unit of the department and randomized using the WINPEPI software by Abramson to either receive intramuscular pentazocine or alternating doses of pentazocine and acetaminophen over the first 48hours after surgery. The pain scores, side effect profile and the time taken for the return of bowel sounds were compared among the two groups using relevant statistical methods with IBM SPSS version 20 with Z tests and chi-square to test for strength of relationships of variables. The level of significance was 0.05. RESULTS The average age of the participants was 29.82years with standard deviation 6.138; 64.8% were Hausa-Fulani, 71.83% were Muslims, 45.07% were unemployed, 97.89% were married, 42.2% were multiparous, 59.86% booked in our centre and 59.2% were having their first caesarean section. Seventy-six participants received combination of injection pentazocine/acetaminophen while 66 received pentazocine injection alone. The drop-out rate was 8.5%. There was no statistically significant difference in the pain scores both on the visual analogue scale and the verbal rating scale in the first 48hours in both groups, no difference in the need for rescue analgesics (p=0.709), time taken for the return of bowel sounds (P=0.391), incidence of side effects (p=0.394) and participants' level of satisfaction (p=0.255). CONCLUSION Both regimens were comparable in analgesic efficacy, incidence of side effects and satisfaction levels.

We ran this concurrent evaluation to understand the process of intervention delivery. Methods Mixed-methods process evaluation, including field-notes, interviews and post-trial questionnaire responses. Qualitative analysis used the framework method with subsequent creation of comparative case studies, grouping hospitals by intervention fidelity. Post-trial questionnaire was developed using initial qualitative analyses. Categorical variables were summarised as count (percentage) and continuous variables as median (interquartile range (IQR)). Odds ratios (OR) were used to rank influences by impact on fidelity. Results Data-set included eight in-depth case studies, and 96 questionnaire responses (response rate 67%) plus intervention fidelity data for each trial site. 57% (n= 55/96) of hospitals achieved intervention delivery using an inclusive definition of fidelity. Delivery of the ASOS-2 interventions and data collection presented a significant burden to the investigators, outstripping limited resources. The influences most associated with fidelity were: surgical staff enthusiasm for the trial (OR 3.0 (95% confidence interval 1.3-7.0)); nursing management support of the trial (OR 2.6 (1.1-6.5)); performance of a dummy run (OR 2.6(1.1-6.1)); nursing colleagues seeing the value of the intervention(s) (OR 2.1 (0.9-5.7)), and the principal investigator's belief in the effectiveness of the intervention (OR 3.2 (1.2-9.4)). Conclusion ASOS-2 has proved that coordinated interventional research across Africa is possible but delivering the ASOS-2 interventions was a major challenge for many investigators. Future improvement science efforts must include better planning for intervention delivery, additional support to investigators and the promotion of strong inter-professional teamwork.

Methods A 7-day, international, prospective, observational cohort study was done in patients having caesarean delivery in 183 hospitals across 22 countries in Africa. The inclusion criteria were all consecutive patients (aged ≥18 years) admitted to participating centres having elective and non-elective caesarean delivery during the 7-day study cohort period. To ensure a representative sample, each hospital had to provide data for 90% of the eligible patients during the recruitment week. The primary outcome was in-hospital maternal mortality and complications, which were assessed by local investigators. The study was registered on the South African National Health Research Database, number KZ_2015RP7_22, and on ClinicalTrials.gov, number NCT03044899. Findings Between February, 2016, and May, 2016, 3792 patients were recruited from hospitals across Africa. 3685 were included in the postoperative complications analysis (107 missing data) and 3684 were included in the maternal mortality analysis (108 missing data). These hospitals had a combined number of specialist surgeons, obstetricians, and anaesthetists totalling 0•7 per 100 000 population (IQR 0•2-2•0). Maternal mortality was 20 (0•5%) of 3684 patients (95% CI 0•3-0•8). Complications occurred in 633 (17•4%) of 3636 mothers (16•2-18•6), which were predominantly severe intraoperative and postoperative bleeding (136 [3•8%] of 3612 mothers). Maternal mortality was independently associated with a preoperative presentation of placenta praevia, placental abruption, ruptured uterus, antepartum haemorrhage (odds ratio 4•47 [95% CI 1•46-13•65]), and perioperative severe obstetric haemorrhage (5•87 [1•99-17•34]) or anaesthesia complications (11•47 (1•20-109•20]). Neonatal mortality was 153 (4•4%) of 3506 infants (95% CI 3•7-5•0). Interpretation Maternal mortality after caesarean delivery in Africa is 50 times higher than that of high-income countries and is driven by peripartum haemorrhage and anaesthesia complications. Neonatal mortality is double the global average. Early identification and appropriate management of mothers at risk of peripartum haemorrhage might improve maternal and neonatal outcomes in Africa.

Existing risk assessment tools are not valid for use in this population because the pattern of risk for poor outcomes differs from high-income countries. The objective of this study was to derive and validate a simple, preoperative risk stratification tool to identify African surgical patients at risk for in-hospital postoperative mortality and severe complications. Methods: ASOS was a 7-day prospective cohort study of adult patients undergoing surgery in Africa. The ASOS Surgical Risk Calculator was constructed with a multivariable logistic regression model for the outcome of in-hospital mortality and severe postoperative complications. The following preoperative risk factors were entered into the model; age, sex, smoking status, ASA physical status, preoperative chronic comorbid conditions, indication for surgery, urgency, severity, and type of surgery. Results: The model was derived from 8799 patients from 168 African hospitals. The composite outcome of severe postoperative complications and death occurred in 423/8799 (4.8%) patients. The ASOS Surgical Risk Calculator includes the following risk factors: age, ASA physical status, indication for surgery, urgency, severity, and type of surgery. The model showed good discrimination with an area under the receiver operating characteristic curve of 0.805 and good calibration with c-statistic corrected for optimism of 0.784. Conclusions: This simple preoperative risk calculator could be used to identify high-risk surgical patients in African hospitals and facilitate increased postoperative surveillance. Clinical trial registration: NCT03044899.

There are few studies describing surgical outcomes in Africa. We did a 7-day, international, prospective, observational cohort study of patients aged 18 years and older undergoing any inpatient surgery in 25 countries in Africa (the African Surgical Outcomes Study). We aimed to recruit as many hospitals as possible using a convenience sampling survey, and required data from at least ten hospitals per country (or half the surgical centres if there were fewer than ten hospitals) and data for at least 90% of eligible patients from each site. Each country selected one recruitment week between February and May, 2016. The primary outcome was in-hospital postoperative complications, assessed according to predefined criteria and graded as mild, moderate, or severe. Data were presented as median (IQR), mean (SD), or n (%), and compared u...

This study was conceived in a background where the practice of pain relief in labor is evolving and where women are seeking to fulfill their need for pain-free labor. Objective: To investigate the knowledge, utilization and preferences of methods of pain relief in labor by expectant mothers in order to design a labor analgesia program. Materials and Methods: A questionnaire-based descriptive study involving 124 antenatal clients in a teaching hospital over a 1 week period. Descriptive statistics were carried out using SPSS for windows version 17. Results: The mean age of clients was 28.8 years (standard deviation = 5.17) with median parity of two and mean gestational age was 31.5 weeks. Majority of the respondents (47.9%) were of Hausa/Fulani ethnicity and 97.6% had primary school level education. Majority (87.3%) had heard about pain relief methods with the hospital being the source in 79% of cases. The most common method ever heard about was epidural analgesia (69.4%). Only 4% (n = 5) of respondents remembered ever using any form of pain relief agent in labor, of which three received parenteral opioids. In their current pregnancies, 45.2% consented to the use of pain relief in labor; of which, epidural analgesia was preferred by 92.9% (n = 52). Fear of adverse effects on self and infants were cited as reasons for non-consent by some respondents while others had no reason. Conclusion: The study reveals a high awareness of pain relief methods which is not matched by utilization and low knowledge about side-effects, although fear of side-effects is a factor for under-utilization. There is a need to educate adequately as well provide high quality pain relief services in labor in order to dispel with myths, misconceptions and fears associated with the use of methods of pain relief in labor.

Methods: This was a multicenter, collaborative, cross-sectional pilot study of provider perspectives concerning pain relief during labor. A structured, self-administered, questionnaire was completed by 95 consenting maternal health care providers at three high-volume facilities in Zaria, an ancient northern Nigerian city. Descriptive statistics was performed on the data. Results: Most respondents (94.8%) agreed that pain relief is needed during labor. Only 2.1% of respondents were undecided about the provision of pain relief during labor and 3.2% were of the opinion that pain relief was not necessary during labor. Most respondents (93.7%) had attended a woman in labor in the 4 weeks preceding the survey. Of these, 56.8% had counseled a parturient in labor. Most of the counseling (42.1%) took place during labor. Less than half of the respondents (48.4%) had administered pain relief in labor in the preceding 4 weeks and systemic opioids was the most commonly form of pain relief. Among the respondents who did not offer pain relief agents in labor, the majority (54.5%) had no reason for not offering it. Unavailability of methods, inability to afford the cost of pain relief, lack of knowledge and skills, as well as lack of essential equipment to provide the procedure were also given by respondents as reasons for not offering pain relief. Conclusion: Even though maternal health care providers in this environment have a positive attitude to pain relief in labor, most women go through labor without the benefit of analgesia. There exists a gap between provider attitudes to pain relief in labor and practice of the same, with many providers having no genuine reason(s) for not offering pain relief to their clients during labor. Providers need to align their practice to their attitudes, and need to be helped to do this through training as well as enhancing their ability to think critically about their practice.

Pain may be of diagnostic and therapeutic origin such as lumbar puncture, bone marrow aspiration, or venipuncture. The aim of this review is to sensitise all health care providers to appreciate, prevent and control pain in children. Relevant literature from selected references on the current concepts of paediatric pain management was reviewed. Various pain assessment modalities indicate that pain is a common accompaniment and complication of paediatric surgery. Pain in children is under diagnosed and under treated in our environment. The popular dogma that “children do not feel pain” and “powerful analgesics may lead to drug addiction” is erroneous and misleading. CONCLUSION: Concerted efforts are required to enhance our understanding of the mechanisms of pain in children and its diagnosis and treatment. Fears of the side effects of analgesics and anaesthetics s...

It comes at a time when all surgical specialties are concentrating on sub specialization and anaesthesia seems to be lagging behind. No stone should be left unturned by anaesthetists to ensure that manpower development and sub specialization becomes a reality the world over. Aims/Objectives: The aim of this paper is to critically evaluate the World Federation of Societies of Anaesthetists (WFSA) Education programme with a view to analyze the impact of the Fellowship training on our manpower development. Materials/Methods: An overview of the current training programme is presented and the authors experience at Edith Wolfson Medical Center, Holon Israel is discussed. Results: Quite a number of Anaesthetists have benefited from this training programme and are back to their locations, to put in to practice what they learnt. Conclusion: It is important that Societies of Anaesthetists in various countries in conjunct...

We compared the ease of endotracheal intubation following sevoflurane and propofol-suxamethonium induction using Helbo–Hansen score. Patients and Methods: A prospective, randomized double-blinded comparative study conducted on sixty-six children (two groups of 33 each) between the ages of 3–10 years undergoing different elective surgeries. Group I received intravenous propofol and intravenous suxamethonium while Group II had inhalational induction with sevoflurane in 60% nitrous oxide and oxygen. Data including intubating conditions, time to tracheal intubation and haemodynamic changes were analysed using SPSS version 18, with statistical significance set at P < 0.05. Results: Using the Helbo–Hansen intubation score, the study reveals that 28 patients (85%) scored...

An easy-to-administer, adequate and safe analgesia will encourage usage in neonatal circumcision. Orally administered ketamine may prove effective and safe, and may encourage procedural analgesia use in neonatal circumcision. Aim: To determine the analgesic efficacy of oral ketamine in Plastibell® neonatal circumcision. Materials and Methods: A hospital based randomised double blind controlled study was conducted at the paediatric surgery unit of the hospital, from March 2015 to December 2015. Total 121 neonates were sequentially recruited, and randomised into two groups. Group A received oral ketamine, and Group B received plain syrup (placebo) as procedural analgesia. Continuous pulse oximeter monitoring was done before, during and immediately after the procedure. The pre-procedural and intra-procedural peripheral oxygen saturation (SpO2) and Pulse Rate (PR) were determined a...

Most of these deaths occur on hospital wards after the surgery itself. We aimed to assess whether enhanced postoperative surveillance of adult surgical patients at high risk of postoperative morbidity or mortality in Africa could reduce 30-day in-hospital mortality. Methods We did a two-arm, open-label, cluster-randomised trial of hospitals (clusters) across Africa. Hospitals were eligible if they provided surgery with an overnight postoperative admission. Hospitals were randomly assigned through minimisation in recruitment blocks (1:1) to provide patients with either a package of enhanced postoperative surveillance interventions (admitting the patient to higher care ward, increasing the frequency of postoperative nursing observations, assigning the patient to a bed in view of the nursing station, allowing family members to stay in the ward, and placing a postoperative surveillance guide at the bedside) for those at high risk (ie, with African Surgical Outcomes Study Surgical Risk Calculator scores ≥10) and usual care for those at low risk (intervention group), or for all patients to receive usual postoperative care (control group). Health-care providers and participants were not masked, but data assessors were. The primary outcome was 30-day in-hospital mortality of patients at low and high risk, measured at the participant level. All analyses were done as allocated (by cluster) in all patients with available data. This trial is registered with ClinicalTrials.gov, NCT03853824. Findings Between May 3, 2019, and July 27, 2020, 594 eligible hospitals indicated a desire to participate across 33 African countries; 332 (56%) were able to recruit participants and were included in analyses. We allocated 160 hospitals (13 275 patients) to provide enhanced postoperative surveillance and 172 hospitals (15 617 patients) to provide standard care. The mean age of participants was 37·1 years (SD 15·5) and 20 039 (69·4%) of 28 892 patients were women. 30-day in-hospital mortality occurred in 169 (1·3%) of 12 970 patients with mortality data in the intervention group and in 193 (1·3%) of 15 242 patients with mortality data in the control group (relative risk 0·96, 95% CI 0·69–1·33; p=0·79). 45 (0·2%) of 22 031 patients at low risk and 309 (5·6%) of 5500 patients at high risk died. No harms associated with either intervention were reported. Interpretation This intervention package did not decrease 30-day in-hospital mortality among surgical patients in Africa at high risk of postoperative morbidity or mortality. Further research is needed to develop interventions that prevent death from surgical complications in resource-limited hospitals across Africa.

Prediction of a difficult airway can help reduce the incidence of failed or difficult intubation. We studied the use of “L-E-M-O-N” (Look-Evaluate-Mallampati-Obstruction-Neck mobility) scoring system to predict difficult intubation and determine the prevalence of difficult intubation among adult surgical patients. Materials and Methods: One hundred and sixty (160) consecutive ASA I–III surgical patients between 18 and 65 years of age were recruited from October to December 2011. A variety of airway tests using the “L-E-M-O-N” scoring were done during preoperative assessment; and at induction of anesthesia, airway assessment using Cormack and Lehane was performed and the results were recorded by a standardized record sheet. The variables evaluated were gender, age, weight, height, body mass index (BMI), dentition and a variety of airway tests using the “L-E-M-O-N” scale. SPSS version 17.0 was used for statistical analysis; and a P value <0.05 was considered significant. Results: Prevalence of difficult intubation using Cormack and Lehane score only was found to be 8.1%. The “LOOK” features had sensitivities of 99.1%, 96.6%, and 92.5% for facial trauma, large incisors, and beard or moustache, respectively, and positive predictive values of 0%. Combination of predictors in the “L-E-M-O-N” score showed that, as the mean “L-E-M-O-N” score of the patients increased, the likelihood of difficult visual laryngoscopy also increased. Conclusion: Combination of airway predictors in the “L-E-M-O-N” scoring system significantly improves the ability to predict difficult intubation.

The place of pain management in cancer patients cannot be over emphasized. Proper management results in improved quality of life. Aims: To assess providers′ attitude and practice toward cancer pain management in Ahmadu Bello University (ABU) Teaching Hospital, Zaria, Nigeria. Materials and Methods: This was a cross-sectional descriptive pilot study on provider perspectives on pain management in cancer patients. A structured self-administered questionnaire was completed by 79 medical practitioners of various specialties and ranks. Results: Seventy-nine clinicians were recruited for the study. The majority of the respondents, 36 (46%), believe that pain was the commonest symptom in cancer patients. Most, 61 (78%), of the doctors assessed pain using subjective methods and only 30 (29%) of the respondents were conversant with other treatment options for pain. Fifty (64.3%) use analgesia, and their choices were guided mainly by the response of the patients. Forty-eight (61.5%) of those who admit to the use of analgesia, were actually limited by the side effects of the drugs. More than half (57.6%) believed that pain management in our settings is suboptimal, and the commonest limitation to optimal pain management in our settings was availability and affordability of drugs. Conclusion: Professional education needs to focus on the proper assessment of pain, the management of side effects of analgesics, and the use of adjuvant therapies for pain. A better understanding of the pharmacology of opioid analgesics is also needed.

It is a safe drug in unskilled hands and a drug of choice in high-risk patients. We report an unusual allergic reaction to Ketamine in a 2.5-year-old child with bilateral congenital inguinal hernia. This is to alert all practitioners to some of the rare but potentially fatal side effects of Ketamine. Anaphylactic reactions to Ketamine are a rare but potentially fatal occurrence. Management includes treatment of acute reactions and avoidance of future reactions. There is no known antidote or reversal agent to Ketamine. So, once it is administered, one must be ready for it to complete full duration of its action. Facilities for resuscitation must be available any time an anesthetic is being administered, no matter how short or minor the surgery is.

Despite the reported low bioavailability, it could exhibit novel role in clinical pain management. Objective: To investigate the systemic analgesic and anti-inflammatory effects of RSV in comparison to diclofenac and etoricoxib. Materials and Methods: Following institutional ethics approval, the study was conducted in the physiology research laboratory. The animals (42 male Wistar rats) used were divided into seven groups (n = 6) in separate cages. Chemical pain was evaluated using formalin-induced nociception test. Statistical analysis was done using analysis of variance and Kruskal–Wallis statistical tests. Results: There is a significant change in nociceptive score in the early phase; however, no significant changes in the late phase in the formalin test. Anti-inflammatory studies showed that RSV 50 mg/kg has a significantly potent anti-inflammatory effect when compared to control, but similar in activity to etoricoxib. Tumor necrosis factor alpha and interleukin-2 concentration did not significantly differ between the groups. Conclusion: RSV may elicit its analgesic actions by inhibiting the direct activation of nociceptors. It may be suggested that systemic RSV at a dose of 50 mg/kg in Wistar rats significantly reduces inflammation comparable to etoricoxib, but possibly less potent than diclofenac. Thus, RSV may be useful in the management of acute and chronic pain with significant inflammatory components. Further broad based human clinical studies on the analgesic and anti-inflammatory properties of resveratrol are required to confirm its potential role in clinical pain management.

Patients and Methods: One hundred and ten parturients of American Society of Anesthesiologists' I and II scheduled for cesarean section under spinal anesthesia were randomized into two groups. Group A (n = 55) received 5 IU IV bolus of oxytocin and Group B (n = 55) received 10 IU IV bolus of oxytocin after delivery. Ten milliliters per kilogram of 0.9% saline was administered to both groups as volume preload. Subarachnoid block was performed with size 24G spinal needles at L2/L3 or L3/L4 intervertebral space with the patients in sitting position. Two milliliters of 0.5% heavy bupivacaine was administered slowly intrathecally. Following delivery of the baby, IV boluses of 5 IU (Group A) or 10 IU (Group B) of oxytocin were administered slowly, and recording of heart rate, systolic, diastolic, and mean arterial blood pressure was done every minute for 5 min after bolus injection. IV infusion of 30 IU of oxytocin in 500 ml of 0.9% saline (60 mU/ml) at a rate of 125 ml/h was continued in both groups till the end of surgery. Estimated blood loss (EBL) was assessed by visual estimation. Patients were monitored continuously until 24 h after surgery to evaluate PDPH and PONV. Results: There were no statistically significant differences in the EBL between the two groups. There was no significant rise in heart rate and no significant decrease in mean arterial blood pressure in Group A compared to Group B. The incidence of PDPH and PONV was also comparable in both groups. Conclusion: Five IU of IV bolus of oxytocin is as effective as 10 IU of IV bolus in reducing blood loss during cesarean section.

Though many modalities for pain management exist, there is the need to investigate safer and affordable regimens that will provide adequate analgesia with minimal side effects and with ease of administration. Alternating doses of intramuscular acetaminophen and intramuscular pentazocine was studied as an alternative to provide safe and effective post-caesarean section analgesia. Its effectiveness and side effect profile in our environment have not been previously investigated. AIMS AND OBJECTIVES The study aimed to compare the analgesic and side effect profile of intramuscular pentazocine with another regimen involving alternating doses of pentazocine and acetaminophen within the first 48hours after surgery. DESIGN OF THE STUDY This was a prospective, comparative and randomized study among 142 women who voluntarily consented to the study and had elective caesarean section from May 2014 to May 2015 at the Ahmadu Bello University Teaching Hospital, Zaria. Setting: The Study was conducted at the obstetrics and gynecology department of the teaching hospital of Ahmadu Bello University, Zaria. MATERIALS AND METHODS Consecutive eligible pregnant women who were slated for elective caesarean section were recruited at the antenatal clinic unit of the department and randomized using the WINPEPI software by Abramson to either receive intramuscular pentazocine or alternating doses of pentazocine and acetaminophen over the first 48hours after surgery. The pain scores, side effect profile and the time taken for the return of bowel sounds were compared among the two groups using relevant statistical methods with IBM SPSS version 20 with Z tests and chi-square to test for strength of relationships of variables. The level of significance was 0.05. RESULTS The average age of the participants was 29.82years with standard deviation 6.138; 64.8% were Hausa-Fulani, 71.83% were Muslims, 45.07% were unemployed, 97.89% were married, 42.2% were multiparous, 59.86% booked in our centre and 59.2% were having their first caesarean section. Seventy-six participants received combination of injection pentazocine/acetaminophen while 66 received pentazocine injection alone. The drop-out rate was 8.5%. There was no statistically significant difference in the pain scores both on the visual analogue scale and the verbal rating scale in the first 48hours in both groups, no difference in the need for rescue analgesics (p=0.709), time taken for the return of bowel sounds (P=0.391), incidence of side effects (p=0.394) and participants' level of satisfaction (p=0.255). CONCLUSION Both regimens were comparable in analgesic efficacy, incidence of side effects and satisfaction levels.

We ran this concurrent evaluation to understand the process of intervention delivery. Methods Mixed-methods process evaluation, including field-notes, interviews and post-trial questionnaire responses. Qualitative analysis used the framework method with subsequent creation of comparative case studies, grouping hospitals by intervention fidelity. Post-trial questionnaire was developed using initial qualitative analyses. Categorical variables were summarised as count (percentage) and continuous variables as median (interquartile range (IQR)). Odds ratios (OR) were used to rank influences by impact on fidelity. Results Data-set included eight in-depth case studies, and 96 questionnaire responses (response rate 67%) plus intervention fidelity data for each trial site. 57% (n= 55/96) of hospitals achieved intervention delivery using an inclusive definition of fidelity. Delivery of the ASOS-2 interventions and data collection presented a significant burden to the investigators, outstripping limited resources. The influences most associated with fidelity were: surgical staff enthusiasm for the trial (OR 3.0 (95% confidence interval 1.3-7.0)); nursing management support of the trial (OR 2.6 (1.1-6.5)); performance of a dummy run (OR 2.6(1.1-6.1)); nursing colleagues seeing the value of the intervention(s) (OR 2.1 (0.9-5.7)), and the principal investigator's belief in the effectiveness of the intervention (OR 3.2 (1.2-9.4)). Conclusion ASOS-2 has proved that coordinated interventional research across Africa is possible but delivering the ASOS-2 interventions was a major challenge for many investigators. Future improvement science efforts must include better planning for intervention delivery, additional support to investigators and the promotion of strong inter-professional teamwork.

Methods A 7-day, international, prospective, observational cohort study was done in patients having caesarean delivery in 183 hospitals across 22 countries in Africa. The inclusion criteria were all consecutive patients (aged ≥18 years) admitted to participating centres having elective and non-elective caesarean delivery during the 7-day study cohort period. To ensure a representative sample, each hospital had to provide data for 90% of the eligible patients during the recruitment week. The primary outcome was in-hospital maternal mortality and complications, which were assessed by local investigators. The study was registered on the South African National Health Research Database, number KZ_2015RP7_22, and on ClinicalTrials.gov, number NCT03044899. Findings Between February, 2016, and May, 2016, 3792 patients were recruited from hospitals across Africa. 3685 were included in the postoperative complications analysis (107 missing data) and 3684 were included in the maternal mortality analysis (108 missing data). These hospitals had a combined number of specialist surgeons, obstetricians, and anaesthetists totalling 0•7 per 100 000 population (IQR 0•2-2•0). Maternal mortality was 20 (0•5%) of 3684 patients (95% CI 0•3-0•8). Complications occurred in 633 (17•4%) of 3636 mothers (16•2-18•6), which were predominantly severe intraoperative and postoperative bleeding (136 [3•8%] of 3612 mothers). Maternal mortality was independently associated with a preoperative presentation of placenta praevia, placental abruption, ruptured uterus, antepartum haemorrhage (odds ratio 4•47 [95% CI 1•46-13•65]), and perioperative severe obstetric haemorrhage (5•87 [1•99-17•34]) or anaesthesia complications (11•47 (1•20-109•20]). Neonatal mortality was 153 (4•4%) of 3506 infants (95% CI 3•7-5•0). Interpretation Maternal mortality after caesarean delivery in Africa is 50 times higher than that of high-income countries and is driven by peripartum haemorrhage and anaesthesia complications. Neonatal mortality is double the global average. Early identification and appropriate management of mothers at risk of peripartum haemorrhage might improve maternal and neonatal outcomes in Africa.

Existing risk assessment tools are not valid for use in this population because the pattern of risk for poor outcomes differs from high-income countries. The objective of this study was to derive and validate a simple, preoperative risk stratification tool to identify African surgical patients at risk for in-hospital postoperative mortality and severe complications. Methods: ASOS was a 7-day prospective cohort study of adult patients undergoing surgery in Africa. The ASOS Surgical Risk Calculator was constructed with a multivariable logistic regression model for the outcome of in-hospital mortality and severe postoperative complications. The following preoperative risk factors were entered into the model; age, sex, smoking status, ASA physical status, preoperative chronic comorbid conditions, indication for surgery, urgency, severity, and type of surgery. Results: The model was derived from 8799 patients from 168 African hospitals. The composite outcome of severe postoperative complications and death occurred in 423/8799 (4.8%) patients. The ASOS Surgical Risk Calculator includes the following risk factors: age, ASA physical status, indication for surgery, urgency, severity, and type of surgery. The model showed good discrimination with an area under the receiver operating characteristic curve of 0.805 and good calibration with c-statistic corrected for optimism of 0.784. Conclusions: This simple preoperative risk calculator could be used to identify high-risk surgical patients in African hospitals and facilitate increased postoperative surveillance. Clinical trial registration: NCT03044899.

There are few studies describing surgical outcomes in Africa. We did a 7-day, international, prospective, observational cohort study of patients aged 18 years and older undergoing any inpatient surgery in 25 countries in Africa (the African Surgical Outcomes Study). We aimed to recruit as many hospitals as possible using a convenience sampling survey, and required data from at least ten hospitals per country (or half the surgical centres if there were fewer than ten hospitals) and data for at least 90% of eligible patients from each site. Each country selected one recruitment week between February and May, 2016. The primary outcome was in-hospital postoperative complications, assessed according to predefined criteria and graded as mild, moderate, or severe. Data were presented as median (IQR), mean (SD), or n (%), and compared u...

This study was conceived in a background where the practice of pain relief in labor is evolving and where women are seeking to fulfill their need for pain-free labor. Objective: To investigate the knowledge, utilization and preferences of methods of pain relief in labor by expectant mothers in order to design a labor analgesia program. Materials and Methods: A questionnaire-based descriptive study involving 124 antenatal clients in a teaching hospital over a 1 week period. Descriptive statistics were carried out using SPSS for windows version 17. Results: The mean age of clients was 28.8 years (standard deviation = 5.17) with median parity of two and mean gestational age was 31.5 weeks. Majority of the respondents (47.9%) were of Hausa/Fulani ethnicity and 97.6% had primary school level education. Majority (87.3%) had heard about pain relief methods with the hospital being the source in 79% of cases. The most common method ever heard about was epidural analgesia (69.4%). Only 4% (n = 5) of respondents remembered ever using any form of pain relief agent in labor, of which three received parenteral opioids. In their current pregnancies, 45.2% consented to the use of pain relief in labor; of which, epidural analgesia was preferred by 92.9% (n = 52). Fear of adverse effects on self and infants were cited as reasons for non-consent by some respondents while others had no reason. Conclusion: The study reveals a high awareness of pain relief methods which is not matched by utilization and low knowledge about side-effects, although fear of side-effects is a factor for under-utilization. There is a need to educate adequately as well provide high quality pain relief services in labor in order to dispel with myths, misconceptions and fears associated with the use of methods of pain relief in labor.

Methods: This was a multicenter, collaborative, cross-sectional pilot study of provider perspectives concerning pain relief during labor. A structured, self-administered, questionnaire was completed by 95 consenting maternal health care providers at three high-volume facilities in Zaria, an ancient northern Nigerian city. Descriptive statistics was performed on the data. Results: Most respondents (94.8%) agreed that pain relief is needed during labor. Only 2.1% of respondents were undecided about the provision of pain relief during labor and 3.2% were of the opinion that pain relief was not necessary during labor. Most respondents (93.7%) had attended a woman in labor in the 4 weeks preceding the survey. Of these, 56.8% had counseled a parturient in labor. Most of the counseling (42.1%) took place during labor. Less than half of the respondents (48.4%) had administered pain relief in labor in the preceding 4 weeks and systemic opioids was the most commonly form of pain relief. Among the respondents who did not offer pain relief agents in labor, the majority (54.5%) had no reason for not offering it. Unavailability of methods, inability to afford the cost of pain relief, lack of knowledge and skills, as well as lack of essential equipment to provide the procedure were also given by respondents as reasons for not offering pain relief. Conclusion: Even though maternal health care providers in this environment have a positive attitude to pain relief in labor, most women go through labor without the benefit of analgesia. There exists a gap between provider attitudes to pain relief in labor and practice of the same, with many providers having no genuine reason(s) for not offering pain relief to their clients during labor. Providers need to align their practice to their attitudes, and need to be helped to do this through training as well as enhancing their ability to think critically about their practice.

Pain may be of diagnostic and therapeutic origin such as lumbar puncture, bone marrow aspiration, or venipuncture. The aim of this review is to sensitise all health care providers to appreciate, prevent and control pain in children. Relevant literature from selected references on the current concepts of paediatric pain management was reviewed. Various pain assessment modalities indicate that pain is a common accompaniment and complication of paediatric surgery. Pain in children is under diagnosed and under treated in our environment. The popular dogma that “children do not feel pain” and “powerful analgesics may lead to drug addiction” is erroneous and misleading. CONCLUSION: Concerted efforts are required to enhance our understanding of the mechanisms of pain in children and its diagnosis and treatment. Fears of the side effects of analgesics and anaesthetics s...

It comes at a time when all surgical specialties are concentrating on sub specialization and anaesthesia seems to be lagging behind. No stone should be left unturned by anaesthetists to ensure that manpower development and sub specialization becomes a reality the world over. Aims/Objectives: The aim of this paper is to critically evaluate the World Federation of Societies of Anaesthetists (WFSA) Education programme with a view to analyze the impact of the Fellowship training on our manpower development. Materials/Methods: An overview of the current training programme is presented and the authors experience at Edith Wolfson Medical Center, Holon Israel is discussed. Results: Quite a number of Anaesthetists have benefited from this training programme and are back to their locations, to put in to practice what they learnt. Conclusion: It is important that Societies of Anaesthetists in various countries in conjunct...

We compared the ease of endotracheal intubation following sevoflurane and propofol-suxamethonium induction using Helbo–Hansen score. Patients and Methods: A prospective, randomized double-blinded comparative study conducted on sixty-six children (two groups of 33 each) between the ages of 3–10 years undergoing different elective surgeries. Group I received intravenous propofol and intravenous suxamethonium while Group II had inhalational induction with sevoflurane in 60% nitrous oxide and oxygen. Data including intubating conditions, time to tracheal intubation and haemodynamic changes were analysed using SPSS version 18, with statistical significance set at P < 0.05. Results: Using the Helbo–Hansen intubation score, the study reveals that 28 patients (85%) scored...

An easy-to-administer, adequate and safe analgesia will encourage usage in neonatal circumcision. Orally administered ketamine may prove effective and safe, and may encourage procedural analgesia use in neonatal circumcision. Aim: To determine the analgesic efficacy of oral ketamine in Plastibell® neonatal circumcision. Materials and Methods: A hospital based randomised double blind controlled study was conducted at the paediatric surgery unit of the hospital, from March 2015 to December 2015. Total 121 neonates were sequentially recruited, and randomised into two groups. Group A received oral ketamine, and Group B received plain syrup (placebo) as procedural analgesia. Continuous pulse oximeter monitoring was done before, during and immediately after the procedure. The pre-procedural and intra-procedural peripheral oxygen saturation (SpO2) and Pulse Rate (PR) were determined a...

Most of these deaths occur on hospital wards after the surgery itself. We aimed to assess whether enhanced postoperative surveillance of adult surgical patients at high risk of postoperative morbidity or mortality in Africa could reduce 30-day in-hospital mortality. Methods We did a two-arm, open-label, cluster-randomised trial of hospitals (clusters) across Africa. Hospitals were eligible if they provided surgery with an overnight postoperative admission. Hospitals were randomly assigned through minimisation in recruitment blocks (1:1) to provide patients with either a package of enhanced postoperative surveillance interventions (admitting the patient to higher care ward, increasing the frequency of postoperative nursing observations, assigning the patient to a bed in view of the nursing station, allowing family members to stay in the ward, and placing a postoperative surveillance guide at the bedside) for those at high risk (ie, with African Surgical Outcomes Study Surgical Risk Calculator scores ≥10) and usual care for those at low risk (intervention group), or for all patients to receive usual postoperative care (control group). Health-care providers and participants were not masked, but data assessors were. The primary outcome was 30-day in-hospital mortality of patients at low and high risk, measured at the participant level. All analyses were done as allocated (by cluster) in all patients with available data. This trial is registered with ClinicalTrials.gov, NCT03853824. Findings Between May 3, 2019, and July 27, 2020, 594 eligible hospitals indicated a desire to participate across 33 African countries; 332 (56%) were able to recruit participants and were included in analyses. We allocated 160 hospitals (13 275 patients) to provide enhanced postoperative surveillance and 172 hospitals (15 617 patients) to provide standard care. The mean age of participants was 37·1 years (SD 15·5) and 20 039 (69·4%) of 28 892 patients were women. 30-day in-hospital mortality occurred in 169 (1·3%) of 12 970 patients with mortality data in the intervention group and in 193 (1·3%) of 15 242 patients with mortality data in the control group (relative risk 0·96, 95% CI 0·69–1·33; p=0·79). 45 (0·2%) of 22 031 patients at low risk and 309 (5·6%) of 5500 patients at high risk died. No harms associated with either intervention were reported. Interpretation This intervention package did not decrease 30-day in-hospital mortality among surgical patients in Africa at high risk of postoperative morbidity or mortality. Further research is needed to develop interventions that prevent death from surgical complications in resource-limited hospitals across Africa.

Prediction of a difficult airway can help reduce the incidence of failed or difficult intubation. We studied the use of “L-E-M-O-N” (Look-Evaluate-Mallampati-Obstruction-Neck mobility) scoring system to predict difficult intubation and determine the prevalence of difficult intubation among adult surgical patients. Materials and Methods: One hundred and sixty (160) consecutive ASA I–III surgical patients between 18 and 65 years of age were recruited from October to December 2011. A variety of airway tests using the “L-E-M-O-N” scoring were done during preoperative assessment; and at induction of anesthesia, airway assessment using Cormack and Lehane was performed and the results were recorded by a standardized record sheet. The variables evaluated were gender, age, weight, height, body mass index (BMI), dentition and a variety of airway tests using the “L-E-M-O-N” scale. SPSS version 17.0 was used for statistical analysis; and a P value <0.05 was considered significant. Results: Prevalence of difficult intubation using Cormack and Lehane score only was found to be 8.1%. The “LOOK” features had sensitivities of 99.1%, 96.6%, and 92.5% for facial trauma, large incisors, and beard or moustache, respectively, and positive predictive values of 0%. Combination of predictors in the “L-E-M-O-N” score showed that, as the mean “L-E-M-O-N” score of the patients increased, the likelihood of difficult visual laryngoscopy also increased. Conclusion: Combination of airway predictors in the “L-E-M-O-N” scoring system significantly improves the ability to predict difficult intubation.

The place of pain management in cancer patients cannot be over emphasized. Proper management results in improved quality of life. Aims: To assess providers′ attitude and practice toward cancer pain management in Ahmadu Bello University (ABU) Teaching Hospital, Zaria, Nigeria. Materials and Methods: This was a cross-sectional descriptive pilot study on provider perspectives on pain management in cancer patients. A structured self-administered questionnaire was completed by 79 medical practitioners of various specialties and ranks. Results: Seventy-nine clinicians were recruited for the study. The majority of the respondents, 36 (46%), believe that pain was the commonest symptom in cancer patients. Most, 61 (78%), of the doctors assessed pain using subjective methods and only 30 (29%) of the respondents were conversant with other treatment options for pain. Fifty (64.3%) use analgesia, and their choices were guided mainly by the response of the patients. Forty-eight (61.5%) of those who admit to the use of analgesia, were actually limited by the side effects of the drugs. More than half (57.6%) believed that pain management in our settings is suboptimal, and the commonest limitation to optimal pain management in our settings was availability and affordability of drugs. Conclusion: Professional education needs to focus on the proper assessment of pain, the management of side effects of analgesics, and the use of adjuvant therapies for pain. A better understanding of the pharmacology of opioid analgesics is also needed.

It is a safe drug in unskilled hands and a drug of choice in high-risk patients. We report an unusual allergic reaction to Ketamine in a 2.5-year-old child with bilateral congenital inguinal hernia. This is to alert all practitioners to some of the rare but potentially fatal side effects of Ketamine. Anaphylactic reactions to Ketamine are a rare but potentially fatal occurrence. Management includes treatment of acute reactions and avoidance of future reactions. There is no known antidote or reversal agent to Ketamine. So, once it is administered, one must be ready for it to complete full duration of its action. Facilities for resuscitation must be available any time an anesthetic is being administered, no matter how short or minor the surgery is.

Despite the reported low bioavailability, it could exhibit novel role in clinical pain management. Objective: To investigate the systemic analgesic and anti-inflammatory effects of RSV in comparison to diclofenac and etoricoxib. Materials and Methods: Following institutional ethics approval, the study was conducted in the physiology research laboratory. The animals (42 male Wistar rats) used were divided into seven groups (n = 6) in separate cages. Chemical pain was evaluated using formalin-induced nociception test. Statistical analysis was done using analysis of variance and Kruskal–Wallis statistical tests. Results: There is a significant change in nociceptive score in the early phase; however, no significant changes in the late phase in the formalin test. Anti-inflammatory studies showed that RSV 50 mg/kg has a significantly potent anti-inflammatory effect when compared to control, but similar in activity to etoricoxib. Tumor necrosis factor alpha and interleukin-2 concentration did not significantly differ between the groups. Conclusion: RSV may elicit its analgesic actions by inhibiting the direct activation of nociceptors. It may be suggested that systemic RSV at a dose of 50 mg/kg in Wistar rats significantly reduces inflammation comparable to etoricoxib, but possibly less potent than diclofenac. Thus, RSV may be useful in the management of acute and chronic pain with significant inflammatory components. Further broad based human clinical studies on the analgesic and anti-inflammatory properties of resveratrol are required to confirm its potential role in clinical pain management.
