Continuous Subacromial Bupivacaine

June 21, 2011 updated by: Turku University Hospital

The Analgesic Effect of Continuous Subacromial Bupivacaine Infusion After Arthroscopic Shoulder Surgery: a Randomized Controlled Trial

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.

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.
