Anesthetic effect of ultrasound-guided brachial plexus nerve block anesthesia in elderly patients with comminuted distal radius fractures and its influences on serum Cor and NE levels
Objective To investigate the anesthetic effect of ultrasound-guided brachial plexus nerve block anesthesia in elderly patients with comminuted distal radius fractures and its influences on serum cortisol(Cor)and norepinephrine(NE)levels.Methods A total of 200 elderly patients with comminuted distal radius fractures who underwent surgical treatment from October 2021 to October 2022 were selected as the research objects.According to the lottery method,the patients were divided into control group and study group,with 100 cases in each group.Both groups underwent brachial plexus nerve block anesthesia,the control group was anesthetized by anatomical positioning method,and the study group was anesthetized under ultrasound-guided.The anesthesia effect,completion time of anesthesia,onset time of sensory block,local anesthetic dosage,cognitive function,serum Cor,NE levels and complications were compared between the two groups.Results The excellent and good rate of anesthesia in the study group was higher than that in the control group(P<0.05).The completion time of anesthesia and the onset time of sensory block in the study group were shorter than those in the control group,and the local anesthetic dosage was less than that in the control group(P<0.05).At 1 and 3 d after operation,the Mini-Mental State Examination(MMSE)score of the study group was higher than that of the control group(P<0.05).At 5 min of anesthesia and at the end of anesthesia,the levels of Cor and NE in the study group were lower than those in the control group(P<0.05).The total incidence of complications in the study group was lower than that in the control group(P<0.05).Conclusion Ultrasound-guided brachial plexus nerve block anesthesia has a significant anesthetic effect in the operation of comminuted distal radius fractures in the elderly,it is beneficial to shorten the time of anesthesia and the onset time of sensory block,reduce the local anesthetic dosage,and has little effect on the cognitive function of patients,and has high safety.
