EFFECT OF ROPIVACAINE AND FENTANYL ON POSTOPERATIVE ANALGESIA OF KNEE ARTHROSCOPY

[Objective] To evaluate the analgesic effect of intra-articular ropivacaine and fentanyl. [Methods] Ninety patients of knee arthroscopy were randomly divided into three groups with 30 patients in each group. At the end of the operation, before the tourniquet released, the patients in the following groups were respectively given an intra-articular injection through the arthroscope: 0.9% normal saline in Group NS; 100 mg ropivacaine in Group R; and 100 mg ropivacaine and 50 μg fentanyl in Group RF. After the operation, pain intensity was measured using the 100-mm visual-analog scale (VAS), and the amount of the supplemental analgesics was recorded for 24 h. [ Results] The VAS scores at the awaking moment, and 0.5, 1, 2, 4, 8 hours after operation were significantly lower in Group RF than in Group NS and Group R (P﹤0.05). The VAS scores at the awaking moment, and 0.5, 1, 2, 4, 8, 24 hours after operation on mobilization were significantly lower in Group RF than in Group NS and Group R (P﹤0.05). Group RF consumed significantly fewer meloxicam tablets than Group NS and Group R (P﹤0.05). [Conclusion] The intra-articular injection of ropivacaine and fentanyl can reduce the patient’s pain and reduce the 24-h supplemental requirement for analgesics after operation.
