Clinical Trial Summary

Purpose: To explore effects of ultrasound-guided quadratus lumborum block with compound lidocaine and esketamine on postoperative pain after colorectal surgery.


Clinical Trial Description

Poor post-surgical pain control is a leading factor that hinders the physicalrehabilitation, and causes acute cognitive impairment and chronic painsyndrome. Recently, the multimodal analgesia strategies to minimise opioidrelated side effects are highly desirable in open surgical procedures. Quadratus lumborum block is a novel technique. Although ropivacaine is most commonly used forthis technique, the analgesic duration remains not dissatisfied. Compared with ropivacaine, compound lidocaine injection has a better and longer analgesic activity since it contains menthol and ethanol with appropriate concentrations. However, whether compound lidocaine injection is efficiency in the quadratus lumborum block for abdominal surgery lacks investigations. Herein, we will evaluate the efficacy of ultrasound-guided quadratus lumborum block (USG-QLB) with compound lidocaine injection and esketamine for postoperative analgesia in patients undergoing colorectal surgery. ;
