阿司匹林对经外周静脉置入中心静脉导管相关性血栓的预防作用

目的评估阿司匹林对经外周静脉置入中心静脉导管（PICC）相关性血栓的预防作用。方法将360例接受PICC置管的肿瘤患者随机分为对照组和试验组两组，每组180例。对照组按照常规方法进行PICC置管后，给予常规PICC导管维护；试验组除按照常规进行PICC置管，给予常规PICC导管维护外，给予100mg阿司匹林每日1次口服，连续21d。观察两组患者的静脉炎和血栓发生情况。结果试验组患者的静脉炎和血栓发生率分别为3．3％和0，明显低于对照组的8．9％（P=0．025）和1．7％（P=0．025）。结论PICC置管后给予口服阿司匹林可降低PICC相关性血栓和静脉炎的发生。

Effectiveness of aspirin in preventing peripherally inserted central venous catheter-related thrombosis

Objective To evaluate the effectiveness of aspirin in preventing peripherally inserted central venous catheter (PICC) -related thrombosis. Methods Totally 360 cancer patients who had undergone routine PICC placement were equally randomized into aspirin group (receiving conventional PICC maintenance plus oral administration of aspirin; 100 mg/d, for consecutively 21 days) and control group (conventional PICC catheter maintenance). The incidences of phlebitis and thrombosis were observed in both two groups. Results The incidences of phlebitis and thrombosis were 3.3% and 0 in aspirin group, which were significantly lower than those in control group (8.9% , P = 0. 025; 1.7% , P = 0. 025). Conclusion The oral administration of aspirin after the PICC placement can reduce PICC-related thrombosis and phlebitis.
