Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The aim of the study is to compare the analgesic nociception index (ANI), which is used to determine the dose of analgesic agent needed in the intraoperative period, with the conventional method in patients with erector spinae block who underwent gynecological surgery under general anesthesia.
