Abstract:
BACKGROUND: Arthroscopic shoulder surgery is often associated with severe postoperative pain. It is important to control pain in this setting, not only to improve the patient's well-being but also to facilitate rehabilitation. The aim of this study was to investigate the efficacy of a continuous suprascapular nerve block for pain relief after arthroscopic shoulder surgery. METHODS: Forty patients (20 in each group) scheduled for elective arthroscopic shoulder surgery received a suprascapular nerve block and a catheter was introduced before surgery. The patients were received standardized general anesthesia. After surgery, a single bolus of normal saline (Group I) or 0.2% ropivacaine (Group II) 6 ml was injected through a catheter in each group. All patients received either a continuous infusion of normal saline (Group I) or a continuous infusion of 0.2% ropivacaine (Group II) through the catheter at a rate of 3 ml/hr plus a bolus of 3 ml with a lock out time of 30 min. Pain relief was assessed at 2, 4, 8, 12, 24 hours using visual analog scale (VAS) and verbal pain scores (VPS). RESULTS: VAS and VPS were lower in the ropivacaine group (Group II) than in the normal saline group (Group I). There were no complication in either group. CONCLUSIONS: Continuous suprascapular nerve block using 0.2% ropivacaine is a safe and efficacious treatment for postoperative shoulder pain.
