Postoperative Pain
Conditions
Keywords
noise blocking, Postoperative Pain
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.
Interventions
Intervention of wearing noise-canceling earphones after general anesthesia

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| 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 |
| 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 |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| 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 |
