ABSTRACT
Objective: To compare the clinical characteristics, quality, complications and patient satisfaction with interscalene brachial plexus block using a nerve stimulator versus the paresthesia technique for shoulder and proximal humerus surgery.
Methods: A randomized clinical trial with two groups of participants was conducted at the National Center of Rehabilitation; group N stands for the neurostimulation group and group P for the paresthesia group. In both groups we used the same type, dose and volume of local anesthetic. Quality, success, latency, duration and complications in shoulder and proximal humerus bone surgery, were evaluated.
Results: Seventy-eight patients participated in the study (N= 40; P= 38). Both groups were similar in their general characteristics. The block quality was the same in both groups. The success rate was 90% in group N and 89.47% in group P with no statistically significant difference (p › 0.05). Latency and duration were similar in both groups. No transient neurological symptoms or complications appeared in any group. Patients’ satisfaction was higher in group N.
Conclusions: There is no difference in localization of plexus by nerve stimulator method versus paresthesia method for interscalene block in shoulder and proximal humerus surgery. The quality, latency, duration, rate of success and complications were similar in both cases, but the patients’ satisfaction was higher in the nerve stimulator group.
