Using EEG and ANI to Improve Recovery After Gynecological Surgery

Quality of Recovery After Electroencephalogram and Nociception Level-guided Versus Standard Anesthesia Care in Female Patients Undergoing Laparoscopic Gynecological Surgery: A Randomized Controlled Trial

Not applicable Interventional Gangnam Severance Hospital · NCT05936671

What this trial studies

This study evaluates the effectiveness of electroencephalogram (EEG) and Analgesia Nociception Index (ANI)-guided anesthesia in enhancing recovery quality following laparoscopic gynecological surgery. Participants will be randomly assigned to either the EEG-and-ANI-guided anesthesia group or a standard care group. The primary outcome will be assessed using the Quality of Recovery (QoR-15) score on the first postoperative day, while secondary outcomes will include various measures such as remifentanil consumption and postoperative pain scores. The study aims to determine if guided anesthesia can lead to better recovery outcomes compared to traditional methods.

Who should consider this trial

Good fit: Ideal candidates are adult women scheduled for laparoscopic gynecological surgeries such as hysterectomy or myomectomy.

Not a fit: Patients with irregular cardiac rhythms, implanted pacemakers, or those on specific medications may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could lead to improved recovery experiences for patients undergoing laparoscopic gynecological surgeries.

How similar studies have performed: While the use of EEG and ANI in anesthesia is gaining interest, this specific approach has not been widely tested, making it a novel investigation.
