闭式引流在全膝关节置换术中的作用评价

目的 评价闭式引流在骨水泥型全膝关节置换手术中的价值。方法 通过前瞻性随机对照研究,将100例拟行骨水泥型初次全膝关节置换的患者术前随机分成两组,一组行闭式引流（n=50）,一组不予引流（n=50）。分别比较两组患者术后并发症及膝关节功能康复情况。结果 非引流组伤口敷料渗出量大于引流组,但引流组术后伤口总渗出量、术后48h血红蛋白下降值显著高于非引流组。术后肢体肿胀、疼痛评分、深静脉栓塞发生率、软组织瘀斑范围、关节屈曲度、2年随访膝关节感染发生率及功能评分等方面无显著差异。结论 在本研究中未发现明显有力的证据支持应用术中引流。

The use of a closed-suction drain in total knee arthroplasty: a prospective, randomized study

Objective To determine the value of using a closed-suction drain in cemented knee arthroplasty. Methods One hundred patients were prospectively randomized into two groups, one group underwent cemented total knee replacement with a single deep closed-suction drain, and the other group (n = 50) no drain. Results The total blood loss was significantly greater in those with a drain although those without lost more blood into the dressings. There was no statistical difference in the postoperative swelling or pain score, ecchymosis, deep vein thromboses (DVT) , time at which flexion was regained or the incidence of infection at a minimum of two years after surgery in the two groups. Conclusion There is no evidence to support the use of a closed-suction drain in cemented knee arthroplasty.
