Episode 15: Anterior QL Block Does Not Reduce Opioid Consumption After Laparoscopic Hemicolectomy

Proponents of fascial plane blocks argue that their value can be found in opioid reduction and improvement of pain scores. On the other hand, critics argue that the effect size tends to be very small, amounting to a placebo. To address these conflicting ideas, a recent study examined the role of quadratus blocks and analgesia for laparoscopic hemicolectomy. In this month’s RAPM Focus, Editor-in-Chief Brian Sites, MD, joins Jens Borglum, MD, PhD, the senior author of “Anterior quadratus lumborum block does not reduce postoperative opioid consumption following laparoscopic hemicolectomy: a randomized, double-blind, controlled trial in an ERAS setting,” first published in September 2022 ( This fascinating study had 69 patients randomized to receive either an anterior quadratus lumborum block or isotonic saline, a placebo.

Dr. Jens Borglum is a consultant anesthetist, clinical research associate professor, and head of research at Zealand University Hospital, University of Copenhagen, Denmark. His main interests are ultrasound-guided nerve blocks and he is a prolific researcher and contributor to Regional Anesthesia & Pain Medicine. His clinical and research insights during the peer-review process are invaluable.
