The purpose of this study was to determine the analgesic efficacy of subacromial infusion of ropivacaine after arthroscopic rotator cuff repair. 53 patients who underwent arthroscopic rotator cuff repair under general anesthesia were involved in this study. All patients received postoperative NSAID medication (lornoxicam 12mg/day) for 5 days. In 34 patients, a single-dose subacromial injection with 10 ml of 0.75% ropivacaine was administered at the end of surgery and followed by a postoperative subacromial infusion of 0.75% ropivacaine at 2ml/hr for 1 to 4 days (R group). As a control, 19 patients did not receive an injection or infusion of ropivacaine (C group). A visual analog scale pain score and consumption of postoperative additional analgesic were compared between the two groups. In the R group, visual analog scale at the 1st, 2nd and 3rd postoperative days was 4.2±1.7, 3.3±1.3 and 2.3±1.2, respectively. This was significantly lower compared to the 5.9±1.2, 5.3±1.0 and 4.6±0.5 in the C group. Additional suppositories (diclofenac 50mg) and intramuscular injections (pentazocine 15mg) analgesics were administered to 6 patients (18%) and 4 patients (12%) in the R group, and 14 patients (74%) and 8 patients (42%) in the C group, respectively. Subacromial administration of ropivacaine is an efficient analgesic technique to reduce shoulder pain after arthroscopic rotator cuff repair.
