胸部外科术后PICC置管致相关血栓形成的影响因素分析

Risk factors of peripherally inserted central catheter related thrombosis after thoracic surgery

目的:探讨胸部外科术后外周静脉置入中心静脉导管(peripherally inserted central catheter,PICC)致相关静脉血栓形成的影响因素。方法:回顾性分析452例通胸外科患者术后发生PICC相关性静脉血栓的情况。以疾病种类、置管位置、置管种类为主要观察指标,分析PICC相关性静脉血栓发生的因素。结果:452例患者中,发生PICC相关性静脉血栓的患者有32例,发生率为7.08%,居术后并发症首位。其中,疾病种类和置管位置与PICC相关静脉血栓发生有直接关系(P=0.001)。食管癌(2.8)及头臂静脉(3.0)置管导致血栓发生可能性最大。结论:食管癌患者及头臂静脉置管导致PICC相关血栓发生的可能性最大,对于不同疾病种类的患者选择合适穿刺部位是预防PICC血栓发生的关键。

Objective:To investigate the risk factors of peripherally inserted central catheter (PICC) related thrombus in patients with thoracic surgeries complications. Methods:Retrospectively analyzed the clinical data of 452 patients with thoracic surgeries[The data of classification of diseases,catheter position and the type of catheter were included to analyze the risk factor of PICC in this study. Results:32 of 452 patients were found to had PICC related thrombus,the occurrence rate was 7.08% and it was the highest of thoracic surgeries complications[The statistical results showed that there was a strong correlation between classification of diseases or catheter position and PICC related thrombus ( P =0.001)[Both operation of esophageal carcinoma (2.8) and brachiocephalic vein catheterization (3.0) were involved in the incidence of thrombosis. Conclusion:Patients with operation of esophageal carcinoma and brachiocephalic vein catheterization are much easier to have a PICC related thrombosis[The key factor for preventing PICC thrombosis is to select suitable puncture site for patients with different diseases.
