Original description
This randomized, parallel-group, non-inferiority clinical trial aims to evaluate whether an anesthetic swap strategy consisting of sevoflurane followed by desflurane 30 minutes before the end of surgery is non-inferior to continuous desflurane anesthesia with respect to extubation time in adults undergoing elective laparoscopic bariatric surgery. Secondary outcomes include time to achieve a Patient State Index (PSi) greater than 80, time to achieve an Aldrete score of at least 8, incidence of postoperative nausea and vomiting, post-anesthesia care unit length of stay, and desflurane-related costs.Read full original descriptionShow less

Desflurane Versus Sevoflurane-Desflurane Swap in Adults Undergoing Bariatric Surgery: A Randomized Non-Inferiority Trial on Extubation Time

This randomized, parallel-group, non-inferiority clinical trial aims to evaluate whether an anesthetic swap strategy consisting of sevoflurane followed by desflurane 30 minutes before the end of surgery is non-inferior to continuous desflurane anesthesia with respect to extubation time in adults undergoing elective laparoscopic bariatric surgery. Secondary outcomes include time to achieve a Patient State Index (PSi) greater than 80, time to achieve an Aldrete score of at least 8, incidence of postoperative nausea and vomiting, post-anesthesia care unit length of stay, and desflurane-related costs.
