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 1200,000 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.
