AbstractThe quadratus lumborum block (QLB) is a unilateral facial plane block, which extends from T4 to L1 at the paravertebral space. Injecting local anesthetic between the facial plane of the quadratus lumborum muscle and the psoas major muscle provides the block of the referred dermatomes. However, the number of published studies for QLB used in various surgical procedures is limited. In this case report, we share the results of a 46-years-old ASA I female patient, who underwent open surgery for cholecystectomy and right-sided nephrectomy in the same session. After general anesthesia was induced, QLB was performed in the left lateral decubitus position. A convex probe was placed in transversely between the iliac crest and the costal margin at the midclavicular line. 20cc of 0.25% bupivacaine was injected to the facial plane between the quadratus lumborum and psoas major muscles. The surgery lasted 4 hours and completed uneventfully. In the postoperative period, the patient was provided with morphine PCA. After 24 hours, the VAS score was 0, and the total demanded morphine dose was 13 mg. This case report recommends that QLB may be an adequate choice in the postoperative pain management for patients undergoing cholecystectomy and nephrectomy.
