Effect of Noise Blocking During General Anesthesia on Postoperative Pain

Not Applicable

Completed

• Conditions: Postoperative Pain
• Interventions: Device: Wear noise-cancelling earphones

• Registration Number: NCT05540691
• Lead Sponsor: The Second Affiliated Hospital of Chongqing Medical University

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.

Arm && Interventions

Group	Intervention	Description
group 1	Wear noise-cancelling earphones	Intraoperative intervention with noise-canceling earphones was performed to isolate the noise

Primary Outcome Measures

Name	Time	Method
Pain score (NRS score) at 12-24 hours postoperatively	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	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	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	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 Outcome Measures

Name	Time	Method
Patient controlled analgesia pump analgesic consumption	From the time when the surgery was completed until to 24 hours after surgery	Analgesic requirements was assessed by recording the volume of patient controlled analgesia pump
Postoperative hyperalgesia after surgery	from the 30 minutes before the surgery until to 30 minutes after surgery	Postoperative hyperalgesia was measured by the ratio of pressure pain threshold at time when discharged from postanesthesia care unit compare to before surgery
