Summary: Injection of local analgesia shows no difference in pain control according to the injection locations after arthroscopic rotator cuff repair.
Abstract:
Local analgesic injection is a commonly used modality for pain relief after shoulder surgery.
To compare the efficacy of local anesthetic injections after arthroscopic rotator cuff repair among the glenohumeral joint, subacromial space, and both locations.
Between March 2011 and December 2011, 121 consecutive patients who met the following inclusion criteria were enrolled: (1) small to medium-sized full-thickness rotator cuff tear, (2) underwent arthroscopic rotator cuff repair. We excluded patients with concomitant glenohumeral pathologies, previous shoulder surgeries, and tear size larger than 3cm. All patients were randomly organized into three groups. In group 1, 40 patients received a postoperative glenohumeral injection of bupivacaine (20ml) and lidocaine (10ml). In group 2, 42 patients received in the subacromial space with the same regimen. In group 3, 39 patients received the same regimen, half injected into the glenohumeral joint and half in the subacromial space. Visual Analogue Scale (VAS) for pain was measured before surgery, at postoperative 1, 2, 6, 12, and 24 hours. Demerol was used as the rescue analgesic, and the total number of administrations was recorded at each time point.
After postoperative 24 hours, all three groups showed significant reduction of VAS score (p<0.05). However, the VAS scores for pain between each group were not significantly different at any time point. The amount of supplementary analgesic administered was not significantly different among groups (p>0.05).
Injection of local analgesia shows no difference in pain control according to the injection locations after arthroscopic rotator cuff repair.
