Abstract:Objective To evaluate the clinical application value of ultrasound-guided interscalene brachial plexus nerve block anesthesia. Methods 112 cases of patients underwent interscalene brachial plexus nerve block anesthesia in Baoji Hospital Affiliated to Xi'an Medical College from October 2015 to October 2016 were selected, and divided into group A, B, C, according to different anesthesia location methods. 46 cases in group A were given traditional anatomical localization; 30 cases in group B were given nerve stimulator assisted localization; 36 cases in group C were given high-frequency ultrasound-guided localization. The indicators of anesthesia completion time, block beginning time, analgesic maintain time, dosages of narcotic analgesic drugs and anesthetic effect of the three groups were compared. Results Anesthesia completion time of group A was significantly shorter than that of group B and group C (P < 0.05), while there was no significant difference between group B and group C (P > 0.05). Block beginning time of group C was significantly shorter than that of group A and group B (P < 0.05), while there was no significant difference between group A and group B (P > 0.05). Analgesic maintain time of group C was significantly longer than that of group A and group B (P < 0.05), while there was no significant difference between group A and group B (P > 0.05). Dosages of narcotic analgesic drugs of group C were significantly less than those of group A and group B (P < 0.05), while there were no significant differences between group A and group B (P > 0.05). Anesthetic effect score of group C was significantly higher than that of group A and group B (P < 0.05), while there was no significant difference between group A and group B (P > 0.05). Conclusion Ultrasound-guided interscalene brachial plexus nerve block anesthesia has shorter block beginning time, longer analgesic maintain time, less narcotic analgesic drug dosages and better anesthetic effect. It is worthy of clinical application.
