Calgary, Alberta—Previous research demonstrated the efficacy of the quadratus lumborum block in abdominal surgeries, but a new study has concluded that the block is not effective when used in colorectal surgeries.
Researchers concluded that patients receiving the posterior quadratus lumborum block did not need fewer opioids postoperative ly and actually had higher postoperative pain scores than their counterparts who did not have the block as part of a multimodal analgesic regimen.
