Shoulder Arthroplasty, Local infiltration analgesia
Brief summary
The purpose of this study is to determine the efficacy of local infiltration analgesia as compared to 48-hour interscalene block in treating pain after shoulder arthroplasty. The investigators hypothesize a reduced pain score and use of supplemental analgesic medication during the first three postoperative days using local infiltration analgesia.
Interventions
PROCEDURELocal infiltration analgesia
150 ml ropivacaine, of which 100 ml is with adrenalin
PROCEDUREInterscalene catheter
7 ml ropivacaine interscalene block via catheter, subsequently given 5 ml/h and possibility of 5 ml bolus for the first 48 hours.
