Abstract
Objective To study the application effect and safety of interscalene brachial plexus block under B-ultrasound localization in anesthesia of upper limb fracture surgery.Methods From January 2021 to October 2022,64 patients with upper limb fractures admitted to our hospital were selected as the research objects.They were divided into control group and observation group by random number table method,with 32 patients in each group.The control group was treated with traditional brachial plexus block anesthesia,and the observation group was treated with intermuscular sulcus brachial plexus block anesthesia under B-ultrasound positioning.The anesthesia effect,anesthesia clinical operation index,ulnar artery hemodynamics index,pain score and incidence of adverse reactions were compared between the two groups.Results The excellent and good rate of anesthesia in the observation group was 93.75％,which was higher than 81.25％in the control group(P＜0.05).The onset time of anesthesia block and completion time of anesthesia in the observation group were shorter than those in the control group,and the duration of anesthesia was longer than that in the control group(P＜0.05).The resistance index and pulsatility index of the observation group were lower than those of the control group,and the blood flow was higher than that of the control group(P＜0.05).The pain score of the observation group was lower than that of the control group(P＜0.05).The incidence of adverse reactions in the observation group was 6.25％,which was lower than 18.75％in the control group(P＜0.05).Conclusion Interscalene brachial plexus block under B-ultrasound localization can improve the anesthetic effect in upper limb orthopedic surgery,shorten the time of anesthesia block and anesthesia operation,prolong the duration of anesthesia,reduce the pain score and the incidence of adverse reactions,and the ulnar artery anesthesia is more complete,which can improve peripheral blood flow.It is a safe and effective anesthesia method.关键词
