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)
