Evaluating the Effectiveness of Ondansetron Versus Dexamethasone Versus Placebo for the Control of Intraoperative Nausea and Vomiting in Patients Undergoing Lower-segment Caesarean Section Under Spinal Anesthesia

Comparing the Efficacy of Ondansetron, Dexamethasone, and Placebo for the Reduction of Intraoperative Nausea and Vomiting in Patients Undergoing Lower-segment Caesarean Section Under Spinal Anesthesia

The goal of this randomized controlled trial is to evaluate the effectiveness of Ondansetron, Dexamethasone, and Placebo for intraoperative nausea and vomiting in patients undergoing caesarian section under spinal anesthesia. The main question it aims to answer are:

Which drug is the best at reducing the incidence of intraoperative nausea and vomiting.

Which drug is the best at reducing intraoperative pain.

Participants will be randomly divided into three groups, each will be given a different drug labelled A, B, or C.

A rating scale will be used to evaluate the severity of intraoperative nausea and pain. Episodes of vomiting will be recorded.
