Clinical Trial Summary

This study aimed to verify whether an Opioid-free Anesthesia (OFA) could effectively reduce the incidence of PONV after thoracoscopic-assisted surgery compared with standard general anesthesia (OA) regimens.


Clinical Trial Description

Postoperative Nausea and Vomiting (PONV) is one of the most common complications after general anesthesia, which significantly reduces postoperative comfort and satisfaction of patients perioperatively. Meta-analysis showed that Opioid-free Anesthesia (OFA) significantly reduced the risk of postoperative PONV events in patients undergoing gynecology, breast, and abdominal surgery compared with standard general anesthesia (OA). The main hypothesis of the study is that an OFA could reduce the incidence of PONV in patients after thoracoscopic-assisted surgery than OA. ;
