The Role of Quadratus Lumborum Blocks Following Minimally Invasive Hysterectomy

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.
