The Impact of Ultrasound Guided Quadratus Lumbar Muscle Block on the Arcuate Ligament and Traditional Anterior Lumbar Quadratus Block Effect of Postoperative Analgesia on Laparoscopic Hysterectomy
Objective Exploring the effects of ultrasound-guided quadratus lumbar muscle block(QLB)on the arcuate ligament and traditional anterior lumbar quadratus block on postoperative analgesia in laparoscopic hysterectomy.Methods Selecting 80 patients undergoing laparoscopic hysterectomy admitted to our hospital from June 2022 to June 2023 as the research subjects,They were randomly divided into a control group and an observation group,with 30 cases in each group.Observation group receiving QLB on the arcuate ligament and the control group receiving traditional anterior QLB.Compare the effects of two groups of block anesthesia and postoperative analgesia.Results The observation group had a shorter onset time of blockade compared to the control group,the amount of remifentanil used during surgery was less than that of the control group,After 5 minutes,10 minutes,and 20 minutes of block,the number of blocked plane segments was greater than that of the control group,the pain Visual Analog Scale scores at 2 hours,6 hours,12 hours,24 hours,and 48 hours after surgery were lower than those in the control group,the differences between groups were statistically significant(P＜0.05);Comparison of incidence rates of adverse reactions between two groups,there was no statistically significant difference between groups(P＞0.05).Conclusion For patients undergoing laparoscopic hysterectomy,the implementation of ultrasound-guided QLB on the arcuate ligament has advantages such as wide blocking plane,fast blocking effect,good postoperative analgesic effect,and fewer adverse reactions.
