Abstract:
BACKGROUND: Arthroscopic shoulder surgery can result in moderate to severe postoperative pain. This study compared the postoperative analgesic effects of an intra-articular patient-controlled analgesia (PCA) infusion of 0.25% ropivacaine used with or without fentanyl after arthroscopic shoulder surgery. METHODS: Sixty patients undergoing arthroscopic shoulder surgery under general anesthesia were randomly assigned to three groups. After surgery, normal saline 21 ml (group 1; n = 20), and 0.25% ropivacaine 21 ml (group 2 and group 3; n = 20 respectively), was infused into the articular space through a PCA catheter, which was followed by an infusion of normal saline 99 ml (group 1), 0.25% ropivacaine 99 ml (group 2), or 0.25% ropivacaine 99 ml, including fentanyl 400microgram (group 3) through the intra-articular PCA catheter at 2 ml/hr with a bolus dose of 0.5 ml with a lock out time of 15 minutes. The level of pain was assessed using a visual analogue scale (VAS) and a verbal pain score (VPS) 2, 4, 6, 8, 12, 24 and 36 hours after the intra-articular bolus injection. RESULTS: The pain scores were significantly lower after 2, 4, 6 hours in group 2 and 3 than in group 1. However, after 8 hours, the pain scores were significantly lower in group 3 than in the other two groups. CONCLUSIONS: An intra-articular continuous infusion of 0.25% ropivacaine after arthroscopic shoulder surgery is more effective when used in conjunction with 400 microgram fentanyl.
