目的 探讨儿科重症监护室（pediatric intensive care unit，PICU）护士中心静脉导管（central venous catheter,CVC）管理知识水平的现状及影响因素，为相关循证实践提供资料。 方法 2019年11月，采用方便抽样法选择国内6省的6所三级甲等儿童医院的481名PICU护士为研究对象，对其进行CVC管理相关知识的调查。 结果 481名PICU护士CVC管理知识正确率达60%及以上者295人，占61.4%。不同学历、职称、年龄、ICU工作年限的儿科ICU护士的CVC管理知识水平差异均有统计学意义（均P＜0.05），多因素分析显示在同时考虑学历、职称、ICU工作年限及年龄的影响下，学历依然是儿科ICU护士CVC管理知识的影响因素（OR＞1，P＜0.05）。 结论 建议加强CVC管理知识的相关教育培训，提高操作者对CVC管理知识的理论水平，从而提高CVC的护理质量 。

Objective To understand the status quo of the knowledge level of central venous catheter（CVC） maintenance in pediatric intensive care unit（PICU）nurses,and to analyze its influencing factors,so as to provide baseline data for evidence-based practice in the future. Methods In November 2019,481 PICU nurses from 6 tertiary A children’s hospitals in 6 provinces in China were selected as research objects by the convenient sampling method,and their knowledge of CVC management was investigated. Results The correct rate of CVC management knowledge of 481 PICU nurses was 60% or above,accounting for 61.4%.There were statistically significant differences in CVC management knowledge level among PICU nurses with different educational background,professional titles,ages and years of work in ICU (all P＜0.05).Multivariate analysis showed that educational background was still the influencing factor of PICU nurses’ CVC management knowledge when considering the influence of educational background,professional titles,years of work in ICU and ages (OR＞1,P＜0.05). Conclusions It is suggested to strengthen the education and training of CVC management knowledge,improve the theoretical level of operators’ CVC management knowledge,so as to improve the nursing quality of CVC.
