COMPARISON OF INTRAARTICULAR BUPIVACAINE WITH THE ADDITION OF MORPHINE OR FENTANYL FOR ANALGESIA AFTER ARTHROSCOPIC SURGERY

A randomized study on 30 patients undergoing knee arthroscopy was perf ormed. Group I (n = 15) received 50 mg of 0.25% bupivacaine and 1 mg o f morphine, and group II (n = 15) received 50 mg of 0.25% bupivacaine and 100 mu g of fentanyl. The visual analogue scale was recorded at in tervals of 1, 2, 3, 4, 6, 12, 24, and 48 hours after the operation. Su pplementary analgesia requirements were also recorded. In group I, pai n scores were lower than group II (P < .05) during the 1st, 2nd, 3rd, 12th, 24th, and 48th hours. The duration of analgesia on group I was s ignificantly longer than group II. The combination of intraarticular m orphine and bupivacaine has a longer analgesic duration and effect tha n a combination of fentanyl and bupivacaine.
