Abstract:
Objective To evaluate the efficacy of ultrasound-guided quadratus lumborum block for analgesia after laparoscopic cholecystectomy. Methods Sixty American Society of Anesthesiologists physi-cal statusⅠorⅡ patients, aged 18-64 yr, with body mass index of 20-27 kg∕m2 , scheduled for elective laparoscopic cholecystectomy, were divided into 2 groups ( n=30 each) using a random number table meth-od: ultrasound-guided transversus abdominis plane block group ( group T) and ultrasound-guided quadratus lumborum block group (group Q). In T and Q groups, bilateral ultrasound-guided transversus abdominis plane block and quadratus lumborum block were performed after general anesthesia induction, respectively, with 0. 25％ ropivacaine 20 ml for each side. All the patients received patient-controlled intravenous analge-sia with morphine after surgery, and visual analoge scale scores were maintained≤3 in the two groups. The cumulative consumption of morphine was recorded at 2, 4, 6, 12, 24 and 48 h after surgery. The occur-rence of adverse reactions such as nausea, vomiting, pruritus, over-sedation and respiratory depression was observed and recorded in the analgesic period. The operation time for nerve blocks and nerve blocks-related complications such as bleeding, accidental puncture into the abdominal cavity or intestinal injuries were re-corded. Results Compared with group T, the cumulative consumption of morphine was significantly de-creased at 6, 12, 24 and 48 h after surgery in group Q ( P<0. 05) . There was no significant difference in the operation time for nerve blocks between the two groups ( P>0. 05 ) . There were no adverse reactions such as nausea, vomiting, pruritus, over-sedation and respiratory depression or nerve blocks-related compli-cations in the two groups. Conclusion Ultrasound-guided quadratus lumborum block provides better effica-cy than transversus abdominis plane block when used for analgesia after laparoscopic cholecystectomy.
