Cause analysis and nursing care of thrombus associated with central venous catheterimplantation through peripheral vein
经外周静脉置入中心静脉导管相关性血栓形成的原因分析及护理

摘要

目的 探究分析经外周静脉置入中心静脉导管（PICC）相关性血栓形成的原因，以此为依据总结具体护理干预措施。方法 本次选取研究对象213例，均对其实施PICC置管，同时其中19例出现PICC相关性血栓，将其命名为患者组，其余194例未出现血栓，命名为对照组，对19例PICC相关性血栓患者的临床资料进行综合分析，总结可能引起PICC相关性血栓形成的原因，并探讨相关护理措施。结果 对比了患者组、对照组的性别、肿瘤发生部位、导管外径、穿刺部位、导管材质、置入导管顺利程度及留置时间，据数据分析看，两组患者在导管材质、置入导管顺利程度方面存在明显差异（P＜0.05）。结论 导管材质、置入导管顺利程度是PICC相关性血栓形成的主要原因，应重视从导管材料选择、提高置管技巧方面给予护理预防。

Abstract

Objective To explore and analyze the causes of thrombosis associated with central venous catheter (PICC) implantation through peripheral vein, and to summarize the specific nursing intervention measures.
Methods A total of 213 subjects were selected, all of whom were subjected to PICC catheters. Among them, 19 patients with PICC-associated thrombosis were named as the patient group, while the remaining 194 patients without thrombosis were named as the control group. The clinical data of 19 patients with PICC-associated thrombosis were comprehensively analyzed. To summarize the possible causes of PICC-related thrombosis and discuss the relevant nursing measures.
Results Gender, tumor location, catheter outer diameter, puncture site, catheter material, catheter insertion smoothness and retention time were compared between the patient group and the control group. According to data analysis, there were significant differences in catheter material and catheter insertion smoothness between the two groups (P < 0.05).
Conclusion   The material of catheter and the smoothness of catheter placement are the main causes of PICC-related thrombosis. We should pay more attention to the selection of catheter materials and the improvement of catheter placement skills.
