This study compares two groups of patients undergoing a gynecological surgey under general anesthesia: one group in which intraoperative analgesia is guided by the Analgesia-nociception index, and another group in which intraoperative analgesia is managed as in standard practice. The objective is to assess if the Analgesia Nociception Index may result in a decrease in total analgesic drugs consumption, a decrease in post-operative pain and in chronic pain development.
