目的 探究人工膝关节置换术（TKA）后应用冷效应疗法对改善术后疼痛肿胀的护理效果。方法 对2019年1月—2020年1月接受TKA治疗的110例术后发生肢体疼痛肿胀的患者进行研究,随机抽取55例予常规治疗与护理,归为对照组。另55例在上述干预的基础上加用布袋式冷疗垫间断治疗72 h,归为研究组,观察疼痛肿胀改善情况。结果 干预后6 h、24 h、48 h、72 h研究组疼痛（VAS）评分均低于对照组,差异显著（P<0.05）;干预后72 h,两组髌上10 cm、髌下10 cm周径均较干预前缩小,且研究缩小幅度大于对照组,差异显著（P<0.05）。结论 对TKA术后患者应用冷效应疗法能够有效缓解患肢疼痛肿胀,同时结合相应的护理促进患者配合,提高疗效。

Objective To evaluate the effect of cold therapy on limb pain and swelling after total knee arthroplasty （TKA）. Methods From January 2019 to January 2020, 110 patients with postoperative pain and swelling after TKA were randomly assigned to a control group and a study group, with 55 cases in each group. The control group was given routine therapy and nursing; on the basis of the former, the study group was given intermitted treatment with iced therapeutic pad for 72 h. Improvements in limb pain and swelling conditions were observed. Results After 6 h, 24 h, 48 h, and 72 h of designed intervention, the Visual Analogue Scale （VAS） scores of the study group were significantly lower than those of the control group （P<0.05）; after 72 h, the circumferences above 10 cm and below 10 cm of kneecap of the two groups were significantly smaller than before, and the difference of the study group was larger than that of the control group （P<0.05）. Conclusion Cold therapy can effectively relieve limb pain and swelling of TKA patients. In addition, nursing interventions can further enhance the surgical effects of TKA.
