What this trial studies

This observational study aims to investigate the frequency and risk factors associated with postoperative nausea and vomiting (PONV) in patients undergoing elective cesarean sections with spinal anesthesia. Participants will be monitored for nausea and vomiting in the recovery room and during follow-up visits within the first 24 hours post-surgery. The study will utilize a standard management protocol that includes the administration of intrathecal morphine and multimodal antiemetic prophylaxis. Data collected will help identify the incidence of PONV and the factors that may contribute to its occurrence.

Who should consider this trial

Good fit: Ideal candidates are patients requiring elective cesarean sections at a gestational age greater than 37 weeks with a single fetus.

Not a fit: Patients with contraindications to spinal anesthesia or those who have experienced nausea and vomiting in the 24 hours prior to the procedure may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved management strategies for preventing nausea and vomiting in patients undergoing cesarean sections.

How similar studies have performed: Previous studies have shown varying success in managing postoperative nausea and vomiting in similar surgical contexts, indicating that this area of research is both relevant and necessary.
