Abstract

Shoulder arthroscopy is usually performed under general anesthesia or interscalene block. General anesthesia may be contraindicated and interscalene block sometimes fails. We had 8 patients who were at high-risk and, therefore, shoulder arthroscopy and decompression were performed under local anesthesia in the beach-chair position. We used 50 mL of 1% lidocaine; 30 mL were infiltrated into the skin and underlying tissues and into the glenohumeral joint, and the rest was infiltrated into the subacromial joint. Before the infiltration, all patients were given 5 mg midazolam and 0.1 mg fentanyl intravenously. All 8 patients were satisfied with the analgesia provided by the anesthesia. We conclude that arthroscopy and subacromial decompression can be readily performed under local anesthesia in combination with efficient sedation.
