摘　　要：目的探讨老年危重患者中心静脉导管冲封管的有效方式。方法将126例老年危重患者按照中心静脉置管时间顺序随机分为实验组和对照组,实验组采用间断脉冲式冲管加脉冲式正压封管,即输液过程中间断脉冲式冲管(冲管间断时间为4h),输液结束后脉冲式正压封管,脉冲频率均>5个/s;对照组采用普通冲封管法。两组冲封管液体均为生理盐水,比较两组导管内赘生物形成情况、导管堵塞发生率及中心静脉导管留置时间。结果两组导管内赘生物形成情况及导管堵塞发生率比较,差异均有统计学意义(均P<0.05);而两组导管留置时间比较,实验组较对照组延长,但差异无统计学意义(P>0.05)。结论间断脉冲式冲管加脉冲式正压封管(脉冲频率均>5个/s)能有效减少老年患者中心静脉导管内赘生物的形成,降低导管堵塞发生率,延长中心静脉导管留置时间,保证老年危重患者输液治疗的顺利进行。Objective To investigate the elderly critically ill patients with central venous catheter blunt way of tube sealing. Methods 126 elderly critically ill patients in order of central venous catheter were randomly divided into experimental group and control group,experimental group USES intermittent pulse type tube and pulse type positive pressure sealing tube,namely the infusion process of intermittent pulse flushing（wash pipe discontinuous time is 4hours）,pulse type positive pressure after the infusion tube,pulse frequency were greater than 5a/s;control group using common seal tube method,flush seal tube liquid are saline compared two groups of intraductal neoplasm different forming conditions and the incidence of catheter jam. Results Two groups of intraductal neoplasm formation conditions and catheter jam is happening there were statistical differences（P〈0.05）. Conclusion Intermittent pulse type wash pipe and pulse type positive pressure seal tube can effectively reduce the formation of central venous catheter vegetations in elderly patients,reduce the incidence of catheter jam,ensure the elderly critically ill patients with transfusion treatment,central venous catheter indwelling time longer.
