| Summary: | \r\nBackground\r\nPostoperative nausea and vomiting (PONV) are common side-effects following administration of spinal anaesthesia for caesarean section (CS). PONV is reportedly perceived to be more distressing than pain by patients, which necessitates assessment of its incidence to ensure that it is not undertreated and that effective measures are undertaken to address it.\r\n\r\nObjectives\r\nTo study the incidence of PONV and associated factors in patients delivering via CS.\r\n\r\nMethods\r\nA total of 308 healthy parturients undergoing CS under spinal anaesthesia were recruited. This was a single-centre prospective observational study conducted at an academic hospital. The institution standard of practice for spinal anaesthesia for CS was employed and consisted of injecting 1.8 - 2.0 mL of hyperbaric bupivacaine 0.5% solution plus 10 μg fentanyl at the L3/L4 interspace after preloading the patient with intravenous fluid 10 - 15 mL/kg. Phenylephrine boluses were used in managing any spinal-induced hypotension according to standard protocol. The demographic data and patient characteristics were recorded. Complaints of PONV were recorded postoperatively in the recovery room and 3 hours after the procedure. The clinical significance of PONV was assessed using the PONV impact scale.\r\n\r\nResults\r\nOf the 308 enrolled patients, 295 (95.8%) were black, 9 (2.9%) coloured and 4 (1.3%) white. The overall incidences of nausea and vomiting were 2.6% and 9.7%, respectively, with all episodes occurring during the first 3 hours after the procedure. The overall incidence of PONV was 10.1%.
