Overview
Brief Summary
To investigate the effect of noise blocking during general anesthesia on postoperative pain in patients undergoing laparoscopic abdominal surgery. The aim of this study was to determine whether noise blocking can reduce postoperative pain, analgesic use, and its possible effects on intraoperative electrocorticogram.

Outcomes
Primary Outcomes
Pain score (NRS score) at 12-24 hours postoperatively
Time Frame: From 12 hours postoperatively to 24 hours postoperatively
NRS score: Pain was assessed on a scale of 0-10, with 0 being no pain and 10 being most painful
Maximum pain score (NRS score) at 0-24 hours postoperatively
Time Frame: From ending of the surgery to 24 hours postoperatively
NRS score: Pain was assessed on a scale of 0-10, with 0 being no pain and 10 being most painful
Pain score (NRS score) at 0-6 hours postoperatively
Time Frame: From ending of the surgery to 6 hours postoperatively
NRS score: Pain was assessed on a scale of 0-10, with 0 being no pain and 10 being most painful
Pain score (NRS score) at 6-12 hours postoperatively
Time Frame: From 6 hours postoperatively to 12 hours postoperatively
NRS score: Pain was assessed on a scale of 0-10, with 0 being no pain and 10 being most painful
Secondary Outcomes
- Patient controlled analgesia pump analgesic consumption(From the time when the surgery was completed until to 24 hours after surgery)
- Postoperative hyperalgesia after surgery(from the 30 minutes before the surgery until to 30 minutes after surgery)
