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

Normal saline in quadratus lumborum block
After the induction of anesthesia, normal saline is used for bilateral quadratus lumborum block in a volume of 20 mL of each side.
干预措施: Normal saline (Drug)
Ropivacaine in quadratus lumborum block
After the induction of anesthesia, 0.375% ropivacaine is used for bilateral quadratus lumborum block in a volume of 20 mL of each side.
干预措施: Ropivacaine (Drug)
Compound lidocaine in quadratus lumborum block
After the induction of anesthesia, 0.6% compound lidocaine is used for bilateral quadratus lumborum block in a volume of 20 mL of each side.
干预措施: Compound lidocaine (Drug)
Compound lidocaine and esketamine in quadratus lumborum block
After the induction of anesthesia, 0.6% compound lidocaine and 0.4 mg/kg esketamine are used for bilateral quadratus lumborum block in a volume of 20 mL of each side.
