Background: Opioids can produce potent antinociceptive effects by interacting with local opioid receptors in inflamed peripheral tissue. However, reports on pain relief with intra-articular morphine after arthroscopic knee operations are controversial. We examined the effects of analgsia in intraarticular administration of morphine after knee surgery.
Methods: In randomized grouping, we stuided 40 patients undergoing arthroscopic knee surgery. The patients in group B(n=18) received 20㎖ of 0.25% bupivacaine intraarticulary; those in group MB(n=22) received 5㎎ of morphine and 20㎖ of 0.25% bupivacaine. We compaired visual analogue score for pain, the number of patients for the supplemental analgesics and the side effects of drugs between two groups.
Results: Patients in group MB had significantly lower pain scores from 6 to 24hr postoperative period compaired with those in group B(p<0.05). There was less requirement for supplemental analgesics in group MB.
Conclusion: We concluded that intraarticular morphine(5㎎) significantly reduces postoperative pain following knee arthroscopy compaired with the group used bupivacaine only.
