Effect of noise isolation using noise-cancelling headphones during laparoscopic surgery for postoperative pain reduction: A randomized clinical trial
Authors' conclusion
During laparoscopic surgery under general anesthesia, intraoperative noise isolation using noise-cancelling headphones is a safe and effective strategy for relieving postoperative pain and decreasing total opioid analgesic consumption.
Study context
- Population
- Patients undergoing laparoscopic surgery under GA
- Participants
- 90 patients
- Comparison
- Noise-cancelling headphones during surgery vs control
- Primary endpoint
- Maximum movement-evoked pain intensity (10-point NRS)
- Follow-up
- Within 24 h post-surgery
Methodological detailsprospective, parallel-group
- Prospective
- Parallel-group
Primary result
As reported in the abstract
Intervention
2.7
mean · SD 1.0
Control
4.0
mean · SD 1.0
P < 0.001
Secondary outcomes
Total opioid consumption · 24 h post-surgery
P = 0.032
Association of postoperative pain scores with proportion of intraoperative time with noise ≥70 dB
- Significant association in the control group but not the intervention group; an independent risk factor for postoperative pain
