It interested us greatly to read that the quadratus lumborum block (QLB) is routinely used as a regional anesthesia technique at their institution for postoperative pain after hip arthroscopy. At our institution, a study on the analgesic efficacy of the lumbar plexus block demonstrated reduced resting pain scores after hip arthroscopy. However, there were no differences in postanesthesia care unit analgesic usage, postanesthesia care unit pain with movement, or patient satisfaction.3 Therefore, our current approach is the use of multimodal analgesia with a rare postoperative analgesic block for circumstances such as patients with a history of chronic pain. The insight into the QLB serving as both an analgesic block to the hip4 as well as to the peritoneum, as seen by its benefit in laparoscopic gynecologic surgery,5 may be the key to its optimal pain control for hip arthroscopy. Ultimately, additional studies should be performed to determine if QLB is indeed superior to alternatives, such as lumbar plexus block.3
As point of care ultrasound continues to expand in use and the number of practitioners increases, we believe novel applications, such as its use after hip arthroscopy, will continue to provide insight into ways to improve patient satisfaction and perioperative outcomes.
