Brief Summary:
The investigators wanted to re-evaluate the effects of subacromial bupivacaine infusion after shoulder arthroscopy with standard surgical techniques, including rotator cuff operations. The investigators hypothesized that patients having 5.0 mg/ml bupivacaine infusion at a rate of 2 ml/h subacromially would need less opioids than patients receiving a placebo infusion.

Condition or disease Intervention/treatment Phase
Shoulder Arthroscopy Drug: bupivacaine Not Applicable

Detailed Description:
Shoulder surgery has become a routine outpatient procedure. Previously shoulder surgery was associated with intense, occasionally severe postoperative pain and hence considerable use of opioids. Also arthroscopic shoulder surgery, especially rotator cuff procedures, may cause significant pain resulting sometimes in inpatient admission. Subacromial local anaesthetic infusion as a part of a multimodal approach is one commonly used modality to pain relief after shoulder surgery. Nevertheless, it has been criticized recently for its poor benefits and possible adverse effects. On the whole, the scientific evidence of the advantages of local anaesthetic infusions is inconclusive.
