Intentional pain assessment and adequate management to acceptable pain severity using multimodal methods can be achieved in low-middle income countries (LMICs). Aim: Is to assess the e cacy of transversus abdominis plane (TAP) block and satisfaction post cesarean delivery analgesia at Kilimanjaro Christian Medical Centre in Low-Income countries. Methods: The study population consisted of 72 participants who met criteria posted for elective and emergency caesarean section. They were blindly assigned into two groups: group A was the interventional group which received TAP block and standard pain management according to local protocols and consisted of 41 participants and group B was the control group which received standard pain management without TAP block and consisted of 31 participants. In Group A 30ml of 0.25% bupivacaine single shot was deposited in the TAP plane bilaterally for postoperative analgesia. Participants were randomized using a parallel method. Their demographics were recorded before surgery and visual analogue scale was used to assess postoperative pain at rest and on movement, and maternal satisfaction at 0hrs, 6hrs, 12hrs and 24hrs. Results: Total of 72 patients were analyzed using NRS with pain score at 0hr, 6hr and 12hr was signi cantly low by about 50% in Intervened group as compared to control group with (p-value (2 tail) of < 0.001 however at 24 hrs. was 0.272. Participant in group A had extra movements at 0hr, 6hrs and 12hrs with p-value <0.001 as compare to control cut had no signi cant difference when coughing. Martenal satisfaction with pain management was 95.1% with no reported adverse event. Conclusions: Trans Abdominis Plane block when used as part of multimodal pain management is more effective in managing post cesarean pain resulting in less physical limitation and high martenal satisfaction.

Various short courses have been developed to improve patient outcomes in lowand middle-income countries, but none specifically to address postoperative care and complications. We aimed to identify key features of a proposed short-course addressing this topic using a Delphi process with lowand middle-income country anaesthesia providers trained as short-course facilitators. An initial questionnaire was co-developed from literature review and exploratory workshops to include 108 potential course features. Features included content; teaching method; appropriate participants; and appropriate faculty. Over three Delphi rounds (panellists numbered 86, 64 and 35 in successive cycles), panellists indicated which features they considered most important. Responses were analysed by geographical regions: Africa, the Americas, southeast Asia and Western Pacific. Ultimately, panellists identified 60, 40 and 54 core features for the proposed course in each region, respectively. There were high levels of consensus within regions on what constituted core course content, but not between regions. All panellists preferred the small group workshop teaching method irrespective of region. All regions considered anaesthetists to be key facilitators, while all agreed that both anaesthetists and operating theatre nurses were key participants. The African and Americas regional panels recommended more multidisciplinary healthcare professionals for participant roles. Faculty from high-income countries were not considered high priority. Our study highlights variability between geographical regions as to which course features were perceived as most locally relevant, supporting regional adaptation of short-course design rather than a one-size-fits-all model.

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.

The TBI severity was categorized using admission Glasgow Coma Scale scores: mild (14, 15), moderate (9–13), or severe (3–8). The authors investigated outcomes from admission to hospital day 14. The outcome considered was the Glasgow Outcome Scale–Extended, categorized as poor outcome (1–4) and good outcome (5–8). The authors used TBI registry data collected from 2013 to 2017 at a regional referral hospital in Tanzania.RESULTSOf the final 2502 patients, 609 (24%) received surgery and 1893 (76%) did not receive surgery. There were signific...

In this prospective, randomized double-blind study, we determined the efficacy of TAP block in patients undergoing cesarean section. Totally, 62 parturients undergoing cesarean section were randomized in a double-blind manner to receive either bilateral TAP block at the end of surgery with 20 ml of 0.25% bupivacaine or no TAP block, in addition to standard analgesic comprising 75 mg diclofenac 8 hourly and intravenous patient-controlled analgesia (PCA) tramadol. Each patient was assessed at 0, 4, 8, 12, 24, 36, and 48 h after surgery by an independent observer for pain at rest and on movement using numeric rating scale of 0-10, time of 1(st) demand for tramadol, total consumption of PCA tramadol, satisfaction with pain management and side effects. Use of tramadol was reduced in patients given TAP block by 50% compared to patients given no block during 48 h after surgery (P &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;lt; 0.001). Pain scores were lower both on rest and activity at each time point for 24 h in study group (P &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;lt; 0.001), time of first analgesia was significantly longer, satisfaction was higher, and side effects were less in study group compared to control group. Transverse abdominis plane block was effective in providing analgesia with a substantial reduction in tramadol use during 48 h after cesarean section when used as adjunctive to standard analgesia.

There are little data on the prevalence and potential risk factors for postoperative pain in Tanzania. Therefore, we aimed to investigate these at Kilimanjaro Christian Medical Centre in Northern Tanzania. Our goal is to optimize pain management. Methods: A prospective cohort study was carried out from December 2016 to April 2017. Patients ≥18 years admitted for elective general or orthopedic surgery were included in the study. Demographic data were collected during a pre-operative visit, and pain was assessed with a numerical rating scale (NRS 0-10) at 4, 24, 36 and 48 hours postoperatively. A NRS >3 was considered as moderate to severe postoperative pain. Potential risk factors for postoperative pain were identified using univariate and multivariable binary logistic regression analyses. Results: A total of 281 patients were included in the study. The prevalence of postoperative pain was 61%, 73%, 67% and 58% at 4, 24, 36 and 48 hours after surgery, respectively. Pethidine was the most frequently prescribed analgesic for postoperative pain management (85.1%) in the first 24 hours postoperatively; only 1% received paracetamol or diclofenac, and 13% received tramadol. In the multivariable model, general anesthesia and intra-operative analgesia (OR = 3.70, 95% CI 1.70-8.04) were significant risk factors for postoperative pain. Conclusion: Pain is still inadequately managed at Kilimanjaro Christian Medical Centre leading to a high prevalence (73% on the first day after surgery) of reported postoperative pain in this study. It reflects the need for adequate postoperative analgesia, especially in lowand middle-income countries. Further research identifying risk factors in larger cohorts can be performed if adequate analgesia is given.
