Conclusions
Our trail showed that OFA with lidocaine for hysteroscopy is both safe and effective, and allowed faster and better recovery than that associated with general anesthesia with sufentanil, as assessed using QoR-40 scores. This suggests that OFA with lidocaine can be used in hysteroscopy successfully. It indicated that OFA can be performed in ambulatory surgery smoothly and effectively, and that the prospects for the use of lidocaine in anesthesia warrant further investigation.
