Abstract

Background: Midazolam and propofol by virtue of their antiemetic effect were found
individually to reduce the incidence of intraoperative nausea and vomiting. This study
compares the effects of midazolam and propofol in decreasing the incidence of nausea and
vomiting in pregnant women undergoing lower segment caesarean section (LSCS) under
spinal anaesthesia. It also assesses maternal sedation, neonatal outcome and other side effects.
Aim: To compare the effects of subhypnotic dose of midazolam and propofol in prevention
of intraoperative nausea and vomiting in lower segment caesarean section under subarachnoid
block.
Methods: With ethical committee permission the 60 pregnant women were randomly
allocated into 2 groups after taking informed consent. Group M received 0.03mg/kg
midazolam immediately after cord is clamped, Group P received 10 mg propofol immediately
after cord is clamped. Incidence of nausea and vomiting was not according to Bellville
scoring system (0-novomiting, 1-Nausea, 2-Retching, 3_vomiting). The degree of sedation,
hemodynamic changes were noted baseline, after induction, after drug administration, 30
mins after drug administration, 60 mins after drug administration, neonatal out come and side
effects were recorded.
Results: Statistically significant decrease in intraoperative nausea and vomiting in patients
undergoing LSCS under spinal anaesthesia with 10 mg propofol compared to 0.03 mg
midazolam is observed. Degree of sedation, respiratory rate, mean mephentermine
consumption were comparable between two groups and no difference found.
Conclusion: Propofol significantly decreases incidence of intraoperative nausea and
vomiting inches are in section under spinal anaesthesia as compared to midazolam.
