Abstract

<p>The purpose of this study was to evaluate the rate of phrenic nerve palsy after interscalene brachial plexus block with anterior approach for arthroscopic shoulder surgery. A hundred twenty-five patients were enrolled in this study. We used 10 ml of 1％ mepivacaine and 10 ml of 0.75％ ropivacaine for all cases. Postoperative chest X-ray was taken at maximal expiration and maximal inspiration. Phrenic nerve palsy was defined as expiratory and inspiratory diaphragm height less than one vertebral body. The patients were divided into two groups, positive phrenic nerve palsy positive (PNP) group and negative phrenic nerve palsy (nPNP) group. The rate of phrenic nerve palsy was 33.6％ postoperatively. No patient complained of dyspnea during and after the operation. Median age was significantly high in PNP group. Body mass index, induction time for anesthesia, operation time, effectiveness and success rate of nerve block were not significantly difference in both groups.</p>
