We report a case of a 7 year old boy with uncorrected TOF with features of raised intracranialpressure (ICP) due to a cerebral abscess who successfully underwent an emergency craniotomy with drainage at ourinstitution. Keywords: Tetralogy of Fallot, cerebral abscess, anaesthesia, cyanotic, heart disease

It has been used for the staging of lung cancer as well as to determine the cause of Isolated Mediastinal Lymphadenopathy. There is very limited evidence in the literature of its use in Nigeria to assess mediastinal pathology. The aim of this study was to describe our institutional experience with cervical mediastinoscopy. Methods: This study was a retrospective analysis of 40 patients that underwent cervical mediastinoscopy in our institution between March 2007 and February 2013. Results: The indication for Cervical Mediastinoscopy was Isolated Mediastinal Lymphadenopathy in 24 patients (60%) and lung cancer staging in 16 patient (40%). The mean age of the patients was 52.7 + 15.1 years. There were 21 females (52.5%) and 19 males (47.5%). The most commonly biopsied lymph nodes were level 4 in 35 patients (87.5%) and level 7 in 21 patients (52.5%). Malignant diagnosis was made in 16 (66.7%) patients with Isolated Mediastinal Lymphadenopathy and in 13 (81.3%) patients staged for lung cancer. Hospital stay was less than 24 hours in all patients and there were no complications. Conclusion: Cervical Mediastinoscopy is available in Nigeria and has been performed in our institution with high diagnostic yield and no complications. Its increased use, along with the development of other mediastinal biopsy techniques is advocated to increase tissue biopsy of mediastinal pathology, especially for lung cancer and isolated mediastinal lymphadenopathy.

This study sought to demonstrate the post-operative benefit of pre-operative TPVB in patients scheduled for simple mastectomy. Methods: The study was carried out on 60 adult female patients with the American Society of Anesthesiologists physical status Class I to III scheduled for unilateral mastectomy. Pre-operatively, a nerve stimulator was used to locate the paravertebral space thereafter bupivacaine with adrenaline or saline was injected into the space. Post-operatively, intravenous morphine patient controlled analgesia was commenced in the two groups for 24 h after the surgery. In addition, intravenous paracetamol 15 mg/kg was administered 6 hourly for 24 h in both groups. Results: The 24 h morphine consumption was significantly reduced in the bupivacaine group compared to the control group (P = 0.000). The Numerical pain rating score was significantly lower in the bupivacaine group than in the control group in the 1st 6 h; P = 0.001. The time to first request for analgesia was significantly longer in the bupivacaine group than the control group (P = 0.000). Nausea was the major side effect detected and this was significantly higher in the control group (P = 0.024). The morphine sparing effect was 65.7% in the bupivacaine group. Conclusion: The study showed that bupivacaine-based TPVB provided an effective post-operative analgesic and opioid-sparing effect for simple mastectomy when compared with a saline-based control group that received only intravenous morphine patient controlled analgesia and paracetamol.

Double-lumen tubes (DLT) remain the most popular and reliable choice for one lung ventilation especially in adult patients though use in Nigeria is limited. This study aimed to describe the experience in our institution with the use of double-lumen tubes for one lung ventilation. Materials and Methods: This was a retrospective cross-sectional study conducted on all patients who had double-lumen tube intubations for one lung ventilation between March 2008 and Feb 2013. Results: A total of 55 patients (27 males and 28 females, with a mean age of 39.6 ± 15.7 years) had left double-lumen tube intubations during the period. There were 30 left-sided (54.5%) and 25 right-sided (45.5%) surgical procedures performed. Tube position was verified by flexible bronchoscopy in 50 patients (91.9%) and by chest auscultation in 5 patients (9.1%) with satisfactory collapse in all but one of the procedures. The major surgical indications for one lung ventilation were Video-assisted Thoracic Surgery (VATS) in 22 patients (40%) and Heller's cardiomyotomy in 17 (30.9%). There were no mortalities and all patients had a complete recovery with no sequelae attributable to double-lumen tube use or one lung ventilation. Conclusions: One lung ventilation is an integral component of modern anesthetic practice. It can be safely practiced in Nigeria with appropriate equipment and expertise. The use of DLT for OLV to enhance thoracic anesthetic practice should be encouraged in other Nigerian institutions.

We report the case performed in our institution of a 56 year old Nigerian female who underwent Off Pump Coronary Artery Bypass Surgery (OPCAB) for an ostial lesion of the Left Anterior Descending Coronary Artery. The Left Internal Mammary Artery was successfully anastomosed to the Left Anterior Descending Coronary Artery.

The socioeconomic settings of developing countries are different from those in the developed countries. A review of the epidemiology and management of burns in the neonates in Lagos, Nigeria is presented. The case notes of burns in patients less than 29 days-old from 2004 to 2008 in 4 tertiary health institutions in Lagos were retrieved from the Medical Records Department; necessary data were extracted and analyzed. There were 21 neonates with burns within the study period. The incidence of neonatal burns ranged between 0.5 and 2.5%/year. The mean age was 16.38 ± 1.84 days and the mean BSA of 26.00 ± 5.53%. The etiology of burns was thermal in 19(90.5%) and chemical in 2(9.5%). Hypokalemia was common at early stages of their treatment. Burns were sustained at home in 90.5% of the cases. The mortality rate was 43.5%. Inhalation and thermal injuries were associated with most of the deaths. Domestic incidents from flames are the commonest causes of neonatal burns in the study environment. These are associated with prolonged morbidity and high mortality rate. Health education, highlighting methods of prevention should be undertaken in the community. Well equipped burn centers should be established to treat burns in all age groups.

The challenges and constraints to the development of Open Heart Surgery in Nigeria need to be identified and overcome.
