PONV, pain
The rationale of OFA is to avoid the side-effects associated with opioids on patients’ intra-and post-operative outcomes. Lidocaine is a local anesthetic, with analgesic, anti-hyperalgesic and anti-inflammatory properties. It has traditionally been used as an adjuvant during anesthesia; in this study it was administered intravenously.Our findings revealed that, compared to general anesthesia with sufentanil, OFA with lidocaine resulted in higher QoR-40 scores in patients who underwent hysteroscopy. Moreover, lidocaine-OFA showed a shorter time to extubation and a lower incidence of PONV compared to sufentanil. Our findings demonstrate that OFA with lidocaine can provide faster and better postoperative recovery after hysteroscopy.QoR is an important outcome measure of early postoperative health, and it is widely used for assessing patient recovery after anesthesia. The QoR-40 questionnaire includes five items: emotional state, physical comfort, psychological support, physical independence, and pain. The the validity and reliability of the QoR-40 score have been proven [A longer duration of intubation has been demonstrated to result in a higher incidence of mortality [This study has several limitations. First, this was a single-center study; therefore, the generalizability of the findings is limited. Second, we included patients who underwent anesthesia using a laryngeal mask airway to maintain the sevoflurane concentration, which reduced the generality of our findings.
