Abstract
BackgroundPostoperative Nausea and Vomiting (PONV) is a dreadful and uncomfortable experience that significantly detracts patients’ quality of life after surgery. This study aimed to examine the antiemetic effect of a single sub-hypnotic dose of propofol as prophylaxis for PONV.MethodIn this prospective, double-blind, randomized control trial, 345 parturients presented for elective cesarean section at the Obstetric unit of Tamale Teaching Hospital were recruited. Each recruited parturient was randomly assigned to one of three groups; Propofol group (n = 115) represented those who received propofol 0.5 mg/kg, Metoclopramide group (n = 115) represented those who received metoclopramide 10 mg and, Control group (n = 115) represented those who received 0.9% saline. Spinal anesthesia with 0.5% hyperbaric bupivacaine 7.5–10 mg, and intrathecal morphine 0.2 mg was employed for the anesthesia.ResultsThe data indicate that 108 (93.9%) parturients from the control group, 10 (8.7%) from the propofol group and 8 (7.0%) from the metoclopramide group experienced some incidence of PONV. There was no significant difference in the incidence of PONV (nausea, vomiting, and none) between the propofol and the metoclopramide groups (P = 0.99; 0.31; and 0.35 respectively). Parturients who received antiemetic agents were 105 (97.2%), 1 (10.0%) and 3 (37.5%) from the control, propofol and metoclopramide groups respectively. The data indicated that 98 (85.2%) parturients from the control, 3 (2.6%) from propofol group, and 100 (87.0%) from the metoclopramide group experienced some levels of pruritus. There was a significant difference in the incidence of pruritus (mild, moderate, and no pruritus) between the metoclopramide and propofol groups (P < 0.01; P < 0.01; and P < 0.01 respectively).ConclusionA sub-hypnotic dose of propofol is effective as metoclopramide in the prevention of PONV in parturient undergoing cesarean section under spinal anesthesia with intrathecal morphine. Sub-hypnotic dose of propofol significantly reduces the incidence of postoperative pruritus following intrathecal morphine use.Trial registrationCurrent control trial, registered at ISRCTN trial registry: ISRCTN15475205.

The degree of hypotension experienced during the intraoperative period after the subarachnoid blockade indicated that 84 (73.0%) parturients from the control group, 76 (66.1%) from the propofol group, and 89 (77.4%) from the metoclopramide group experienced no degree of hypotension compared with baseline blood pressure
Summary
Postoperative Nausea and Vomiting (PONV) is a dreadful and uncomfortable experience that significantly detracts patients’ quality of life after surgery. Cesarean section is among the most commonly performed surgeries in women, and it is associated with a more intense postoperative pain compared to the post-vaginal delivery pain [1]. The use of spinal anesthesia for cesarean section provides an avenue for rendering better postoperative analgesia with neuraxial opioids [1]. The current practice of using spinal anesthesia with morphine for parturient presenting for elective cesarean delivery in some hospitals has received mixed reactions from both parturient and staff. The addition of intrathecal morphine to bupivacaine offers excellent postoperative analgesia which covers for about 12 to 24 h, some fraction of parturients commonly experiences dose-dependent PONV and pruritus [3]
