Study on Ultrasound-guided Posterior Quadratus Lumborum Block for Analgesia after Cesarean Section
Objective:To compare the analgesic effect of ultrasound-guided posterior quadratus lumborum block(QLB)combined with intravenous analgesia pump and single intravenous analgesia pump in analgesia after cesarean section.Method:From January 2021 to January 2022,100 parturients who scheduled to undergo cesarean section in the First Affiliated Hospital of Baotou Medical College,Inner Mongolia University of Science&Technology were selected as the research objects,they were divided into ultrasound-guided posterior QLB combined intravenous analgesia pump group(QLB+PCIA group,Q group,50 cases)and single intravenous analgesia pump group(C group,50 cases)by random number table method.The pain[visual analogue scale(VAS)],uterine contraction pain,sedation[Ramsay sedation score(RSS)]and comfort[Bruggrmann comfort scale(BCS)score]of two groups were evaluated and recorded at 2 h,4 h,8 h,12 h and 24 h after cesarean section,the number of postoperative intravenous analgesia(PCIA)compressions and adverse reactions were observed and recorded.Result:The VAS score and uterine contraction pain score of Q group at 2 h,4 h,8 h,12 h and 24 h after operation were lower than those of C group,and the numbers of PCIA compressions were less than those of group C,the differences were statistically significant(P<0.05);the BCS score of Q group at 2 h,4 h,8 h and 24 h after operation were higher than those of group C,and the differences were statistically significant(P<0.05);however,there were no significant differences in RSS score at each time point,BCS score at 12 h after operation and incidence of adverse reactions between two groups(P>0.05).Conclusion:The use of ultrasound-guided posterior QLB combined with PCIA after cesarean section can enhance the analgesic effect,reduce the amount of PCIA analgesic drugs,and have better analgesic effect on incision pain and contraction pain,and improve the comfort level of maternal.
