Abstract :
Nausea, and vomiting are common complications in women undergoing cesarean section with
spinal anesthesia. This study aimed to compare the propofol, dexamethasone, and ondansetron effects on nausea
and vomiting. In this double-blind, randomized clinical trial study, 120 women aged 15 to 35 years candidates
for cesarean section under spinal anesthesia were enrolled. Patients were randomly divided into four groups
(three-drug groups and control group). Patients received 0.05 mg/kg ondansetron (group O), 0.1 mg/kg
dexamethasone (group D), 0.2 mg/kg propofol (group P) and normal saline in controls (group C). Nausea and
vomiting in recovery and 6 hours after surgery compared between groups. In recovery and 6 hours after surgery,
both nausea and vomiting were the highest in group C while they were lowest in group O. the frequency of
nausea was 11(36.7%) in both recovery and 6 hours after surgery, and the frequency of vomiting was 12(40%)
and 10(33.3%) in the recovery and 6 hours after surgery respectively. Among three drug groups, nausea and
vomiting were higher in group D in both the recovery room and 6 hours after surgery. The frequency of
vomiting was 10 (33.3%) and 5 (16.7%) in recovery and 6 hours after surgery in group D, respectively. These
differences were statistically significant between the four groups (P<0.05). The preventive effect of
dexamethasone is not very useful in both periods. Therefore, it can be recommended that in the short period
after surgery, propofol has a beneficial effect in preventing postoperative nausea and vomiting.
