The Role of Quadratus Lumborum Blocks Following Minimally Invasive Hysterectomy: A Blinded, Randomized Controlled Trial
In Brief
A Phase 4 clinical trial evaluating Local anesthesia at incision site, Sham QL, and 2 other interventions for Pain, Postoperative. Completed, enrolled 76 participants across 1 site.
Detailed Summary
The purpose of this study is to compare quality of recovery as well as peri-operative systemic opiates use and pain scores in patients undergoing laparoscopic or robotic hysterectomy when local anesthetic versus Quadratus Lumborum nerve block (QL-2) is added to the standard pain management.
Study Details
Timeline
Interventions
20 ml of 0.25% Bupivacaine will be given at incision site
20 mls of normal saline given at QL.The QL block will be administered on both the right and left sides. The transducer is placed transverse immediately cranial to the iliac crest and at the level of the posterior axillary line. The needle is then inserted inplane from the lateral edge of the transducer and advanced through the quadratus lumborum (QL) muscle until the needle tip penetrated the epimysium of the anterior part of the QL muscle. The anesthetic is injected after repeated negative aspiration tests for blood in the fascial interspace between the QL and psoas major (PM) muscles posterior to the transversalis fascia
20 mls of normal saline given at incision site
QL block involves injection of 19 ml of 0.25% Bupivacaine and iml(4mg) of Decadron in a fascial place formed partly by the posterior surface of the quadratus lumborum muscle.The QL block will be administered on both the right and left sides. The transducer is placed transverse immediately cranial to the iliac crest and at the level of the posterior axillary line. The needle is then inserted inplane from the lateral edge of the transducer and advanced through the quadratus lumborum (QL) muscle until the needle tip penetrated the epimysium of the anterior part of the QL muscle.
