摘　　要：目的:评估两种不同冲封管频次(每24 h 1次与每12 h 1次)对1~3岁患儿外周静脉导管堵管率及留置时间的影响。方法:采用随机数字表法将2021年4月—6月3所医院1~3岁住院患儿分为观察组(n=115)和对照组(n=117),分别按照每24 h 1次与每12 h 1次进行脉冲式冲管、正压封管,比较两组患儿留置针堵管发生率和留置时间。结果:意向性分析显示观察组和对照组留置针堵管率分别为10.4%、8.5%,两组比较,差异无统计学意义(P>0.05),差值为-1.9%(95%CI:-9.4%~5.6%),观察组冲封管频次非劣效于对照组。观察组和对照组留置针留置时间分别为(63.74±19.72)h、(68.43±19.52)h,两组比较,差异无统计学意义(P>0.05)。结论:每24 h生理盐水冲封管1次可维持1~3岁患儿外周静脉导管通畅,在不影响其留置时间的前提下节约成本、减轻护士工作量,为幼儿外周静脉导管的维护提供依据。Objective:To compare the effects of normal saline flushing(q24 h vs q12 h)on maintaining the patency and indwelling time of the Peripheral Venous Catheter(PVC)in children aged 1 to 3 years.Methods:We selected hospitalized children aged 1-3 years in 3 hospitals from April to June 2021.Using sealed envelope method,they were divided into q24 h group(n=115)and q12 h group(n=117)and given to pulse tube flushing or positive pressure sealing tube respectively according to different frequency(q24 h vs q12 h).We compared the incidence of tube blocking and indwelling time of PVC between the two groups.Results:Intentional analysis(ITT)showed that the tube blocking rate of PVC in q24 h group and q12 h group were 10.4%and 8.5%,respectively,with no statistical significance(P>0.05),and the difference was -1.9%(95%CI:-9.4%~5.6%),indicating that the non-inferior flushing effect of q24 h was higher than that of q12 h.The indwelling time of PVC in the q24 h group and q12 h group was(63.74±19.72)h and(68.43±19.52)h,respectively,with no significant difference(P>0.05).Conclusion:In the q24 h group,normal saline flushing can maintain the patency of PVC in children aged 1 to 3 years,save costs and reduce the workload of nurses without affecting their indwelling time,and provide a basis for the maintenance of intravenous PVC in young children.
