    [摘要] 目的 比较肝素封管和生理盐水封管在白血病患儿植入静脉输液港中的效果。 方法 采用方便抽样法抽取2015年12月～2017年3月在首都儿科研究所附属儿童医院血液肿瘤科住院的40例白血病患儿，按照时间顺序通过赛丁格技术在外科经右颈内静脉植入静脉输液港；前20例为实验组，后20例为对照组。实验组先10 mL生理盐水在每日输液结束后进行脉冲封管，再采用5 mL生理盐水正压封管。对照组采用常规方法，先使用10 mL生理盐水脉冲冲管，再使用5 mL肝素盐水(10 U/mL)正压封管。观察两种方法封管后输液港在导管堵塞方面是否存在差异。 结果 在连续输液期间，两组的患儿导管堵塞发生率差异无统计学意义(P ﹥ 0.05)。 结论 在连续输液期间，每日只使用生理盐水为植入静脉输液港的白血病患儿进行封管，不会增加管道堵塞的发生概率，值得推广应用。

    [Abstract] Objective To compare the effects of heparin sealing and saline sealing in the implantation of intravenous infusion port in children with leukemia. Methods A total of 40 children with leukemia admitted to the Department of Hematology， Children′s Hospital of Capital Institute of Pediatrics， from December 2015 to March 2017， were selected by sampling technique. All children were surgically passed through the Sytech technique in the right neck. The internal vein was implanted into the intravenous infusion port. The first 20 cases were the experimental group ......
