多普勒超声对于PICC相关血栓形成监测研究

The research of Peripherally Inserted Central Catheters related thrombosis

目的:了解经外周静脉中心静脉置管(PICC)相关血栓形成的发生率以及评估多普勒超声在抗血栓治疗效应。方法:90例患者根据是否定期接受多普勒超声监测分为两组,即定期接受多普勒超声监测的患者(n=40)以及未定期行多普勒超声监测的患者(n=50)。观察分析两组患者中血栓形成的发生率情况。结果:多普勒定期监测组患者中血栓形成的发生率显著低于未监测组(P<0.05)。结论:PICC置管相关性血栓发生率高,而置管后定期进行多普勒超声监测有利于降低血栓发生率。

Objective:To evaluate the incidence of Peripherally Inserted Central Catheters(PICC)relatedthrombosis and the effect of Doppler on anti-thrombosis.Method:A total of90patients were divided into two groupsbased on monitoring of Doppler.There were40patients in test group receiving Doppler regularly and another50patients in non-test group without Doppler.Result:Compared with non-test group,the incidence of PICC relatedthrombosis in test group was lower significantly(P<0.05).Conclusion:PICC is high risk factor associated withthrombosis,however,the regular Doppler test is effective prevention after PICC.
