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.

BACKGROUND: Regional anesthesia techniques are increasingly used in high-income countries (HICs) for both surgical anesthesia and postoperative analgesia. However, regional anesthesia has not been utilized to the same degree in low-to middle-income countries (LMICs) due to a lack of resources and trained personnel. This study evaluates patient satisfaction with, and outcomes of, ultrasound-guided regional anesthesia for extremity surgery at Kilimanjaro Christian Medical Center (KCMC) in the Northeastern zone of Tanzania. METHODS: Study patients were ≥18 years of age; American Society of Anesthesiologists (ASA) physical status I, II, or III; and underwent extremity surgery under peripheral nerve block with ultrasound guidance at KCMC. After placement, blocks were assessed for effectiveness intraoperatively, as demonstrated by the need for supplemental analgesic or sedative medication or conversion to a general anesthetic. Postoperatively, patients were assessed for satisfaction with their nerve block and pain at 12 and 24 hours. Adverse events related to regional anesthesia were assessed immediately, 45 minutes after block placement, and at 12 and 24 hours postoperatively. The primary outcome was patient satisfaction at 12 hours. Secondary outcomes were block success rate and analgesia at 12 and 24 hours postoperatively. RESULTS: A convenience sample of 170 patients was included in the study, of whom 156 (95% confidence interval [CI], 87-95) were either satisfied or very satisfied with their block. Block placement was highly successful with only 8 of 170 participants (95% CI, 2.4-8.3), requiring conversion to a general anesthetic. Analgesia continued in the postoperative period, with 164 of 170 (95% CI, 93-98) patients and 145 of 170 (95% CI, 80-90) patients reporting acceptable analgesia at 12 and 24 hours, respectively. No major adverse events, such as local anesthetic toxicity, infection, bleeding, nerve injury, or pneumothorax, were observed. CONCLUSIONS: Our study found that ultrasound-guided regional anesthesia in a resource-constrained setting was effective for extremity surgery and resulted in high patient satisfaction. No complications occurred. The use of ultrasound-guided regional anesthesia shows promise for the safe and effective care of patients undergoing extremity surgery in LMICs. (Anesth Analg 2024;138:180-6) KEY POINTS• Question: Can ultrasound-guided regional anesthesia be effective in a resource-constrained setting? • Findings: Ultrasound-guided regional anesthesia can result in high patient satisfaction and be highly effective in a resource-constrained setting. • Meaning: Emphasizing training of anesthesia providers in low-to middle-income countries in regional anesthesia techniques may help reduce the high morbidity and mortality associated with general anesthesia and surgery in resource-constrained settings.
