RESUMO

Objective To investigate the effects between the modified and classic coracoid approach in infraclavicular brachial plexus nerve block.Methods Sixty patients scheduled for elective surgical procedures under infraclavicular brachial plexus block were divided into observation group and control group by table of random digit method with 30 cases each.The puncture point of control group was approach via the point 2 cm medial and caudal to the coracoid process.The puncture point of observation group was modified by surface projection of the brachial plexus.Peripheral nerve stimulator was used to confirm the proper localization of the plexus.The performance time,number of puncture,anesthesia success rate,incidence of complications and 24 h patient satisfaction were recorded.Results The performance time in observation group was less than that in control group [(3.2 ± 1.1) min vs.(4.3 ± 1.4) min](P< 0.05).The chance of locating the brachial plexus in a single puncture without adjusting the block needle in observation group was significantly higher than that in control group [73.3% (22/30) vs.50.0% (15/30)] (P < 0.05).There were no statistical differences in anesthesia success rate,incidence of complications and 24 h patient satisfaction between two groups (P > 0.05).Conclusions The modified coracoid approach can significantly improve the probability of locating the nerve in one puncture that reduces the performance time.It can improve the accuracy of puncture point position on the body surface.
