What this trial studies

This clinical trial aims to evaluate the effectiveness of two different combinations of antiemetic medications in preventing intraoperative nausea and vomiting (IONV) and postoperative nausea and vomiting (PONV) in patients undergoing cesarean sections. Participants will be randomly assigned to receive either ondansetron combined with dexamethasone or ondansetron combined with metoclopramide. The primary objective is to compare the incidence of PONV in the first 24 hours post-surgery. The study addresses a common issue faced by many women during cesarean deliveries, aiming to improve patient satisfaction and outcomes.

Who should consider this trial

Good fit: Ideal candidates for this study are ASA II and III pregnant patients aged 18-40 scheduled for elective cesarean sections under spinal anesthesia.

Not a fit: Patients with ASA physical status greater than III, those with a BMI over 35, or those with a history of motion sickness or allergies to the study medications may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could significantly reduce the incidence of nausea and vomiting in women undergoing cesarean sections, enhancing their recovery experience.

How similar studies have performed: Previous studies have shown the effectiveness of ondansetron in preventing nausea and vomiting, but this specific comparison of combinations is novel.
