Abstract:
AIM: To evaluate the analgesic effects of combining application of low-dose morphine and diprospan in intra-articular injection after knee arthroscopy.METHODS: ① A total of 100 patients with knee arthroscopy were selected from the Surgery of Joint, Department of Orthopaedics, Changzheng Hospital, the Second Military Medical University of Chinese PLA from February 2002 to January 2003, including 52 males and 48 females aged from 16 to 56 years. All of them did not have a history of administration of pain-killer before operation. Patients were classified from grade Ⅰ to grade Ⅱ based on American Society of Anesthesiologists (ASA) before operation. Meanwhile, all the patients did not have obvious histories of heart,lung and liver diseases, and all patients provided informed consent. ② All patients were randomly divided into two groups, including combination group and morphine group with 50 in each group. Patients in the combination group were given intra-articular injection with 1 mg morphine hydrochloride and 1 mL compound diprospan [Xianling Baoya Pharmaceutical Factory, Belgian; batch number: 4JBBKA35A; qualification: 1 mL (5 mg/2 mg)/ampoule] after operation.In addition, patients in morphine group were injected with 1 mg morphine hydrochloride [the First Pharmaceutical Factory, Shenyang; batch number: 020316; qualification: 1 mL (10 mg)/ampoule]. ③ At 8 and 24 hours after administration, when patients maintained the status of standing with both feet and unfolding knee joint, analgesic effect was evaluated by visual analogue scale (VAS). Scores ranged from 0 to 10. The higher the scores were, the severer the painfulness was. Moreover, various side effects were observed at 48 hours after operation. ④ Differences of data were compared with one-way analysis of variance and deep differences between the two groups were compared with q test.RESULTS: A total of 100 patients received knee arthroscopy were involved in the final analysis. ① Visual analogue scale: At 8 hours after administration, scores were similar in combination group to those in morphine group, and the scores were 1.41 ±0.74 and 1.52±0.65, respectively (q =2.72, P ＞ 0.05). At 24 hours after administration, scores were remarkably lower in combination group than those in morphine group, and the scores were 1.46±0.61 and 2.53±1.24,respectively (q =3.42, P ＜ 0.05). ② Adverse events and side effects: Side effects, which were always found out in the application of morphine in vein, were not observed in both combination group and morphine group.CONCLUSION: Combining application of low-dose morphine and compound diprospan has an excellent analgesic effect with intra-articular injection, which is superior to that of the single application of morphine. Meanwhile, the combining application of low-dose morphine and compound diprospan is safe.
