两种镇痛方法在肘关节置换术后镇痛中的效果观察

Observation on the efficacy of two kinds of analgesia after replacement surgery of elbow joint

目的:探讨肘关节置换术后1周内局部冷敷疗法和口服镇痛药物的镇痛效果及副作用。方法:将24例肘关节置换术后患者随机分为A组和B组各12例,A组采用一次性化学冰袋冷敷患侧肘关节、B组口服盐酸曲马多缓释片进行术后镇痛。分别于锻炼结束后0.5h、1.0h、2.0h、3.0h采用数字评价量表(NRS)进行镇痛效果评价。结果:功能锻炼后0.5h、1.0hNRS评分A组优于B组(P<0.05);2.0h、3.0hNRS评分A组与B组比较差异无统计学意义(P>0.05)。结论:肘关节置换术后应用局部冷敷疗法与口服镇痛药物在镇痛效果上均明显有效,但两种方法统计学比较有差异。

Objective ： To explore the efficacy and side effects of both analgesic methods of local cold compress and oral analgesic drugs for postoperative analgesia within 1 week after replacement surgery of elbow joint. Methods： 24 patients with replacement surgery of elbow joint were randomly divided into group A and group B （ 12 cases for each group）. One - time chemical ice bag was used to apply cold compress to the operated elbows of the patients in group A ; Tramadol hydrochloride sustained - release tablets were given to the patients orally for postoperative analgesia in group B. The numeral rating scale was adopted to evaluate the analgesic effect respectively in 0.5 h, 1.0 h, 2.0 hrs. and 3.0 hrs. after exercises. Results ： The NRS scores in 0. 5 h and 1.0 h after functional exercise were higher in group A than those in group B （ P 〈 0. 05 ）, and the difference of NRS scores in 2.0 hrs. and 3.0 hrs. was not statistically significant between group A and B group （ P 〉0. 05 ）. Conclusion： The local cold compress and oral analgesic drugs are all evidently effective for postoperative analgesia after replacement surgery of elbow joint, but the comparison of the two analgesic methods is statistically significant different.
