Objective: To evaluate the efficacy and safety of continuous epidural analgesia (CEA) with butorphanol in elderly patients undergoing hip replacement.
Methods: Sixty patients scheduled for selective hip replacement were randomized into group B (n=30) to receive patient-controlled epidural analgesia (PCEA) with butorphanol and group M (n=30) to receive PCEA with morphine. Their pain distribution at 5 time points, postoperative global score and the adverse effects in 48 h were observed.
Results: The pain distribution at the 5 time points or the global score for postoperative PCEA in 48 h showed no statistically significant difference between the two groups (P<0.05). Analgesia with butorphanol caused less adverse effects (respiratory depression, nausea and vomiting, itching and abdominal distension) than that with morphine (P<0.05).
Conclusion: CEA with butorphanol is safe and effective for the treatment of postoperative pain in elderly patients and causes less adverse effects than morphine.

S Afr J Surg
December 2024
Department of Biostatistics, Faculty of Health Sciences, University of the Free State, South Africa.
Background: Postoperative patients' risk for developing venous thromboembolism (VTE) can be predicted using the adapted Caprini risk assessment model which informs administration of postoperative VTE prophylaxis. The study aimed to assess the appropriateness of postoperative VTE prophylaxis of patients according to the adapted Caprini scores and investigate whether a patient's HIV status influenced postoperative VTE prophylaxis administration.
Methods: This cohort study included patients who had elective or urgent surgery at a tertiary hospital, Bloemfontein.
