Intrathecal Morphine for Enhanced Recovery After Laparoscopic Colorectal Surgery: A Randomized Clinical Trial.
Summary
In 252 adults undergoing laparoscopic colorectal surgery within an ERAS pathway, intrathecal morphine (3 µg/kg) added to liposomal-bupivacaine TAP block improved 24-hour QoR-15 by 12.21 points, reduced opioid consumption and nausea, but increased pruritus. The double-blind RCT supports ITM+TAPB as an effective multimodal analgesia strategy.
Key Findings
- QoR-15 at 24 hours improved by a mean of 12.21 points with ITM+TAPB vs placebo (P<.001).
- Postoperative opioid consumption decreased by a mean of 6.59 MME with ITM (P<.001).
- Nausea incidence decreased (23.8% vs 37.3%; P=.01) while pruritus increased (19.0% vs 3.2%; P<.001).
Clinical Implications
Consider adding intrathecal morphine to TAP block for laparoscopic colorectal procedures within ERAS, with counseling and monitoring for pruritus.
Why It Matters
High-quality randomized evidence demonstrates a practical, implementable enhancement to ERAS analgesia with patient-centered outcomes (QoR-15) improvement.
Limitations
- Single-center study may limit generalizability
- Short-term follow-up focused on early recovery; long-term outcomes not assessed
Future Directions
Multicenter replication with longer follow-up, dose-finding for ITM balancing analgesia and pruritus, and comparative effectiveness versus other neuraxial/peripheral strategies.
