Clinical Observation of Interscalene Brachial Plexus Block / 대한마취과학회지

ABSTRACT

We performed the interscalene technic of brachial plexus block for an operation of the upper extremity in 94 patients. We used 1%, 1.5% or 2% lidocaine solution with or without 1:200,000 epinephrine. There were paresthesias in all cases of needle puncture with the interscalene approach. The resutls were as follows: 1) Onset of anesthesia was observed in 3~10 minutes(average: 5 min.) 2) Complete anesthesia was observed in 10~30 minutes(average: 18 min.) 3) The mean interval of anesthesia to operation was 22 minutes. 4) We observed satisfactory blocks in 81 cases, unsatisfactory block in 8 cases and failure in 5 cases. 5) There were not any complications such as pneumothorax, dyspnea, convulsions, subarachnoid or epidural injection, etc.
