Objectives: The effect of ropivacaine alone or in combination with fentanyl was evaluated on postoperative analgesia and analgesic requirements after arthroscopic knee surgery. Patients and methods: The study included 60 ASA I-II patients (age range 18 to 65 years) undergoing arthroscopic meniscectomy. Following surgery under general anesthesia, the patients were randomly divided into three groups to receive intra-articular physiological saline (controls, n=20), ropivacaine 150 mg (n=20), or ropivacaine 150 mg with fentanyl 50 µg (n=20). The patients were monitored with respect to heart rate and mean arterial pressure, and pain was estimated using a visual analog scale (VAS) after 5, 15, and 30 minutes, and 1, 2, 4, 8, and 12 hours of operation. Analgesic requirements and adverse effects were recorded. Results: There were no significant differences between the two ropivacaine groups with respect to VAS scores and analgesic need (p>0.05). Pain scores in the control group were at all times higher than both ropivacaine groups (p<0.05). A higher analgesic need was observed in the control group, compared to the ropivacaine (p=0.005) and ropivacaine plus fentanyl (p=0.01) groups. Analgesics were used in 10, three, and four patients in the control, ropivacaine, and ropivacaine plus fentanyl groups, respectively. Although analgesic requirement was confined to a single dose in both ropivacaine groups, three patients in the control group received further doses. Conclusion: Intra-articular 150 mg ropivacaine alone was found effective for postoperative analgesia and the adjuvant use of fentanyl did not alter analgesia levels and analgesic needs.
