Analgesic Effect Of Ultrasound-guide Various Quadratus Lumborum Block To Transverse Abdominal Plane Block In Radical Operation Of Ovarian Cancer

Objective: To evaluate the clinical effect of various quadratus lumbar block to transverse abdominal plane block in patients following ovarian cancer.Methods: A total of 90 patients were randomly divided into three groups(n = 30).They were treated with bilateral posterior quadratus lumbar block,anterior quadratus lumbar block or transverse abdominal plane block respectively.Each side was injected with0.375% ropacaine 15 ml.The operation time,puncture success rate and complications were recorded.15 minutes later,all patients were in general anesthesia.The hemodynamic changes,anesthesia during the operation,the incidence of postoperative nausea and vomiting and pain were recorded.The total amount of sufentanil in 24 hours,the first time of rescue analgesia and VAS scores of 1,2,6,12 and 24 h after the operation were also recorded.Results: Compared with the TAPB group,the operation time of QLB2 group and QLB3 group was longer,the difference was statistically significant(P < 0.05);there was one failure case in QLB3 group and QLB2 group respectively;there were two cases of weakness in one side of lower limbs in QLB3 group;the percentage increased of SBP was 4.02% and 1.60% in QLB2 group and QLB3 group respectively,7.18% in TAPB group at the time of skin cutting,.The dosage of sufentanil in QLB 2 group and QLB 3group was significantly lower than that in TAPB group,and that in QLB 3 group was even lower than that in QLB 2 group.There was no significant difference in the VAS scores and PONV incidence between the three groups.Conclusion: Compared with transverse abdominal plane block,ultrasound-guided anterior quadratus lumbar block has a better analgesic effect,which could be an effective alternative to the transverse abdominal plane block.
