Effect of intraoperative noise isolation on postoperative nausea and vomiting in patients undergoing gynecological laparoscopic surgery: protocol for a randomized controlled trial.

ABSTRACT:

Background

Postoperative nausea and vomiting (PONV) are common complications following general anesthesia, particularly in gynecological laparoscopic surgeries. This study aims to evaluate the effect of intraoperative noise isolation on PONV incidence.

Method

This single-center, prospective, randomized controlled trial will enroll 192 adult patients undergoing laparoscopic gynecological surgery. Patients will be randomly assigned in a 1:1 ratio and stratified by age into either the control group (Group C), without noise-cancelling headphones, or a noise reduction group (Group NR), using noise-cancelling headphones from anesthesia induction until the end of surgery. All patients will receive intraoperative dexamethasone and ondansetron prophylaxis. The primary outcome is the
