Effects of ultrasound-guided brachial plexus block with different approaches on anesthesia effect and stress response in elderly patients with humeral fractures
Objective To investigate the effects of ultrasound-guided brachial plexus block with different approaches on anesthesia effect and stress response in elderly patients with humeral fractures.Methods A total of 82 elderly patients with humeral fractures admitted from January 2020 to March 2023 were selected as the research objects.According to different approaches,the elderly patients were divided into group A and group B,with 41 cases in each group.The group A received ultrasound-guided brachial plexus block anesthesia via carotid artery approach,and the group B received ultrasound-guided brachial plexus block anesthesia via retroclavicular approach.The anesthetic effects of the two groups were compared.Results There was no significant difference in the excellent and good rate of anesthesia between the two groups(P>0.05).The onset time of block in the group A was shorter than that in the group B(P<0.05);there were no significant differences in the dosage of anesthesia,the completion time of anesthesia and the maintenance time of analgesia between the two groups(P>0.05).There were no significant differences in the heart rate(HR)and mean arterial pressure(MAP)between the two groups before operation(T0),at skin incision(T1)and immediately after operation(T2)(P>0.05).There were no significant differences in the levels of epinephrine(E)and superoxide dismutase(SOD)between the two groups at T0,T1 and T2(P>0.05).Conclusion Ultrasound-guided brachial plexus block via carotid artery approach and brachial plexus block via retroclavicular approach have similar anesthetic effects on elderly patients with humeral fractures,and with stable hemodynamics and the mild stress response.However,the ultrasound-guided brachial plexus block via carotid artery approach has shorter onset time of block.
