Summary
Effective postoperative pain management is crucial for promoting early recovery and ambulation following laparoscopic colorectal surgery. Regional anesthesia techniques, like interfascial plane blocks, are increasingly being used to achieve this. The quadratus lumborum block (QLB) is a relatively new approach in abdominal surgeries, providing significant pain relief by blocking both somatic and sympathetic nerves. In particular, the anterior QLB technique allows local anesthetic to spread to the thoracic paravertebral space, making it potentially more effective for postoperative analgesia. The hypothesis of this study is that bilateral subcostal anterior QLB can reduce both postoperative pain and opioid consumption in laparoscopic colorectal surgery.
