Effect of ultrasound-guided quadratus lumborum block in analgesia after laparoscopic radical gastrectomy for gastric cancer and its influence on cognitive function
Objective To investigate the effect of ultrasound-guided quadratus lumborum block in analgesia after laparoscopic radical gastrectomy for gastric cancer.Methods Sixty patients undergoing laparoscopic radical gastrectomy for gastric cancer were selected as the research objects.According to the random number table method,the patients were divided into quadratus lumborum block group(30 cases,quadratus lumborum block)and transversus abdominis plane block group(30 cases,transversus abdominis plane block).The analgesic effects of the two groups were compared.Results At 2 and 24 h after operation,the Numeric Rating Scales(NRS)scores at rest and during exercise in the quadratus lumborum block group were lower than those in the transversus abdominis plane block group(P<0.05).At 2 and 24 h after operation,the Bruggrmann Comfort Scale(BCS),Bromage and Mini-Mental State Examination(MMSE)scores of the quadratus lumborum block group were higher than those of the transversus abdominis plane block group(P<0.05).At 2 and 24 h after operation,the levels of malonaldehyde(MDA),cortisol(COR)and superoxide dismutase(SOD)in the quadratus lumborum block group were lower than those in the transversus abdominis plane block group(P<0.05).Conclusion Ultrasound-guided quadratus lumborum block has a good analgesic effect in laparoscopic radical gastrectomy for gastric cancer,but it will affect the normal function of lower limb motor function of the patient to a certain extent.
