Analgesic efficacy, adverse events, and prognostic factors of low-dose intranasal dexmedetomidine combined with epidural anesthesia in ovarian cyst resection

Low-dose intranasal dexmedetomidine combined with epidural anesthesia provides effective analgesia for ovarian cyst resection, with faster onset, reduced postoperative adverse events, and favorable safety. However, awakening time was prolonged in the observation group. Age, cyst diameter, and intraoperative blood loss were independent predictors of postoperative adverse events. Further studies are needed to validate these findings and clarify the effect on awakening time.
