Why the study?
Does intraoperative high oxygen concentration reduce postoperative nausea and vomiting in morbidly obese patients undergoing laparoscopic bariatric surgery?
Does intraoperative high oxygen concentration reduce postoperative nausea and vomiting in morbidly obese patients undergoing laparoscopic bariatric surgery?
Intraoperative administration of 70% oxygen significantly reduces the incidence of postoperative nausea and vomiting and the need for rescue antiemetics in morbidly obese patients undergoing laparoscopic bariatric surgery compared to 30% oxygen.
No immediate change to intraoperative oxygen protocols; leaves open whether concentration affects PONV in bariatric surgery.
