[摘要] 目的 探讨定量抽吸方法减少静脉血液在中心静脉导管尾端及无针接头处的血液残留。 方法 将120例留置中心静脉导管的神经内科重症患者分为对照组62例和观察组58例。对照组采用常规抽吸方法判断留置针是否在静脉内；观察组通过计算主管腔的容量进行定量抽吸。 结果 观察组中心静脉导管尾端及无针接头处残留血液为3.47%，对照组中心静脉导管尾端及无针接头处残留血液为21.92%。 结论 定量抽吸方法可使中心静脉导管尾端及无针接头处残留血液明显减少，可有效防范重症患者中心静脉导管尾端及无针接头处的血液残留。

[Abstract] Objective To explore the quantitative suction way to reduce the blood residue in the end of central venous catheter end and the needle free joint. Methods All 120 severe patients in neurological department with central venous catheter was divided into two groups (59 cases in the control group and 61 cases in the observation group). The control group were used conventional suction way to judge whether indwelling needle was in the vein. The main lumen capacity of the observation group were calculated for quantitative suction. Results The residual blood in the end of central venous catheter and needle free joint of the observation group was 3.42%， which was 21.92% of the control group. Conclusion Quantitative suction way can significantly reduced the residual blood in the end of central venous catheter and needle free joint， which can effectively prevent the residual blood in the end of central venous catheter and needle free joint with severe patients.

目前重症医学科广泛应用由外周静脉插入中心静脉的留置导管，主要用于深静脉营养支持[1]。置入中心静脉导管属侵入性操作，易带来感染问题。由于神经内科危重患者多有神智障碍、肢体瘫痪、排痰及吞咽障碍、排尿排便障碍等因素，造成抵抗力低下、医院感染的问题更为突出。如何做好神经内科危重患者中央导管留置的相关感染的防范，一直是临床护理人员较为关心的护理问题。而中心静脉导管留置部位、无针接头及其连接管的管理是关键点 ......
