Summary Background Risk of mortality following surgery in patients across Africa is twice as high as the global average. 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.

Reports of Investigation Epidural ketamine reduces post-operative epidural PC_& consumption of fentanyl/bupivacainePurpose: To study the analgesic effect of epidural ketamine on postoperative pain and epidural PCA consumption after total abdominal hysterectomy. Methods: Sixty-one AS& I-II patients, 34-60 yr were randomly assigned into three groups. Epidural catheters were inserted before induction of anaesthesia. Patients in group I and II received 30 mg ketamine epidurally before induction of anaesthesia or 20 rain after skin incision: group III received placebo. Postoperatively, on first analgesia request, sedation score, Visual Analogue Scale 0/AS), Pnnce Henry Score (PHS) and Bromage motor weakness score were taken and followed by an epidural bolus of 9 ml bupivacaine 0.25% + 50/./g fentanyl. Analgesia was maintained by PCA with a mixture of bupivacaine 0. ( % + fentanyl 0.00 I% epidura[ly. Measurements were repeated at I, 2, 4, 8, 12 and 24 hr. Results: First analgesia request was 17 _+ 6.8 min in ~e control group compared with 31.4 _+ 23.8 and 44 + 23. I min for groups I and II respectively. The differences between group III and group I (P < 0.0S) and between group III and group II (P < 0.01) were statistically significant. Twenty four hour PCA consumption was I 01.2 ___ 47.2, 87 + 27 and 162 + 38 ml for groups I, II and lU respecthvel~ The differences between group III and group I and that between group III and group II were statistically significant (P < 0.001). Conclusion: Epidural ketamine 30 mg reduces post hysterectomy pain as evidenced by prolongation of time to first analgesia request and reduction in postoperative epidural PCA consumption. This effect is manifest whether ketamine is given before induction or 20 min after skin indsion.
A 28-year-old female presented with a huge intra-abdominal mass. Initially a mesenteric mass was diagnosed, but her tumor was found to be a gastrointestinal stromal tumor (GIST). Laparotomy was performed. The mass was resected en bloc with clear surgical margins in January 2007. It was found to be 20 × 18 × 16 cm. In order to remove the tumor, the left half of transverse colon with its mesocolon, spleen, body and tail of pancreas, and a part of the small intestine had to be removed. The mass was tightly attached to these viscera. The tumor was surgically removed three years ago. The pathology report of the case presented places the tumor in the high-risk category. The tumor had a relatively high mitotic index. It was positive for CD117 and CD34 stains and also positive for smooth muscle actin. Although the patient did not receive adjuvant chemotherapy, no signs of local recurrence or distant metastasis could be recognized on follow up. Surgery remains the standard initial management for all localized GISTs. The tumor should be removed en bloc, with clear surgical margin. The case presented indicates no association of tumor size with early local recurrence of the tumor or early distant metastasis.
