Obj ective:To observe the influence of pediatric peripheral venous catheter using PDCA cycle management act on its retention time and inci-dence of complications.Methods:A total of 160 children undergoing treat-ment of peripheral venous catheter were selected as research objects,80 ca-ses after PDCA cycle management were taken as observation group,another 80 cases before PDCA cycle management were taken as control group,80 cases in control group used nursing intervention with conventional meth-ods,80 cases in observation group used the PDCA cycle management meth-od for planning,program implementation,examination of the results and care interventions to improve the cycle management,to observe and com-pare the general information,retention time,unplanned extubation rate, catheter related complications and nursing satisfaction of two groups of children.Results:The indwelling time of the observation group was longer than that in control group,unplanned extubation rate was lower than that in control group,the incidence of catheter-related infections,blocked tubes, extravasation,phlebitis,prolapse and other complications were lower than those of control group,nursing satisfaction rates was higher than that in control group,the difference was statistically significant(P<0.05).Conclu-sion:The PDCA cycle management method for children was used for nurs-ing intervention management of ill children with pediatric peripheral intrave-nous catheter needle,which can effectively extend the retention time,reduce un-planned extubation rates,reduce the incidence of catheter related complications, and improve nursing satisfaction of the families of the children.%[目的]观察儿科外周静脉留置针采用 PDCA 循环管理法对其留置时间及并发症发生率的影响。[方法]选取160例行外周静脉留置针治疗的小儿为研究对象，其中实行PDCA循环管理后80例为观察组，实行PDCA循环管理前80例为对照组，对照组采用常规护理干预方法，观察组采用 PDCA 循环管理法进行计划制订、计划执行、结果检查、处理改进循环管理的护理干预措施，观察比较两组患儿一般资料、留置时间、非计划拔管率、留置针相关并发症及护理满意度情况。[结果]观察组留置时间长于对照组，非计划拔管率低于对照组，留置针相关的感染、堵管、外渗、静脉炎、脱出等并发症发生率低于对照组，护理满意率高于对照组，差异均有统计学意义(P<0.05)。[结论]采用PD-CA循环管理法对儿科外周静脉留置针患儿进行护理干预管理，能够有效地延长留置时间，降低非计划拔管率，减少留置针相关并发症的发生，提高患儿家属的护理满意度。
