Comparison of safety and efficacy in parturients with cesarean section between ultrasound-guided quadratus lumborum block and transverse abdominis plane block
Objective To investigate the safety and efficacy in cesarean section between ultrasound-guided 1 quadratus lumborum block(QLB)and transverse abdominis plane block(TAPB)in cesarean section.Methods A total of 82 parturients undergoing cesarean section were randomly divided into control and observation groups.Continuous epidural anesthesia was administered in both groups.Under ultrasound guidance,TAPB was conducted on control group,while QLB was conducted on observation group.Two groups were treated with ropivacaine and patient-controlled intravenous analgesia(PCIA)after surgery.Two groups were compared on the first pressing time of analgesic pump,the number of effective pressings within 24 hours,the pain relief rate and postoperative recovery indicators.Two groups were observed on visual analogue scale(VAS)and Bergman Comfort Scale(BCS)at 4,8,12,24,and 48 h after surgery.Sufentanil dosages were compared between two groups at 0-12 h,＞12-24 h,＞24-36 h,and＞36-48 h after surgery.Adverse reactions such as nausea,vomiting and respiratory depression were recorded during hospitalization.Results The first pressing time of the analgesic pump was later in observation group than that in control group.The pain relief rate and the number of effective pressings within 24 hours were lower in observation group than those in control group(P＜0.05).The first maternal standing time,the time to get out of bed after surgery and postoperative colostrum time were lower in observation group than those in control group(P＜0.05).VAS scores at 8,12,24,and 48 h after surgery were lower in observation group than those in control group,but BCS scores at each time point were higher than those in control group(P＜0.05).Sufentanil dosages at 0-12 h,＞12-24 h,and＞24-36 h were lower in observation group than those in control group(P＜0.05).The total incidence of adverse reactions in observation group(7.14％)was lower than that in control group(22.50％,P＜0.05).Conclusion When compared to TAPB,QLB can provide multimodal analgesic effects,reduce sufentanil consumption and minimize adverse reactions for patients undergoing cesarean section,therefore QLB has high clinical value.
