目的：探讨人工膝关节置换术（TKA）后引流管夹闭4h和不夹闭对患者术后出血量的影响。方法TKA患者60例均分为A、B两组。A组术后夹闭引流管4h后开放，B组术后不夹闭引流管。比较两组术后引流量、住院时间及术后并发症的发生率。结果A组术后24‐h引流量较B组少[（512.4±253.5）mlvs．（873.4±301.5）ml]（P＜0．05）；A组术后接受输血治疗患者的比例低于B组（46.7％vs．90.0％）（P＜0．05）。在未输血的患者中，A组术后血红蛋白的下降值低于B组[（15.5±7.2）g／Lvs．（21.8±10.3）g／L]（P＜0．05）。两组患者术后发生切口红肿、发热及康复情况差异无统计学意义。结论TKA术后夹闭引流管4h能有效减少患者术后出血量，不增加患者术后感染及功能恢复的风险。

Objective To observe the effect of clamping drainage tube for 4 hours on postoperative blood loss in the patients underwent total knee arthroplasty (TKA ) .Methods Sixty patients underwent TKA were equally assigned into two groups .The drainage tube in group A was clamped soon after surgery for 4 hours ,which in group B was opened all the time .The blood loss , hospital stay and complications were observed and compared between two groups .Results The postoperative blood loss in 24 hours was significantly less in group A than that in group B [(512.4 ± 253.5)ml vs .(873.4 ± 301.5) ml](P<0 .05) .The percentage of patients needed blood transfusion after operation was significantly lower in group A than that in group B (46.7% vs .90.0% ) (P<0 .05) .The decrease of Hb after operation was less in group A than that in group B in the cases without blood transfution [(15.5 ± 7.2) g/L vs .(21.8 ± 10.3) g/L](P<0 .05) .There were no significant differences in fever ,wound healing and rehabilitation between two groups .Conclusion Clamping drainage tube for 4 hours may effectively reduce postoperative blood loss in the patients underwent TKA without increasing the risk for infection and rehabilitation .
