Continuous wound infusion catheter as part of a multimodal analgesia regimen for post-Caesarean delivery pain: a quality improvement impact study
Authors' conclusion
The addition of continuous wound infusion catheters to a multimodal analgesia regimen for post-Caesarean delivery pain management demonstrated minimal clinically significant analgesic benefits.

Opioid consumption (mg morphine equivalents)
Secondary outcomes
| Outcome | Continuous wound infusion catheter | Control | P value |
|---|---|---|---|
| Resting pain score · 24 hHigher in the control group | 1.5 (interval 0–3) | 2 (interval 1–3) | P = 0.05 |
| Satisfaction score · 24 h | 100% (interval 91–100%) | 90% (interval 86–100%) | P = 0.003 |
