【摘要】：目的探讨新生儿经外周静脉置入中心静脉导管(PICC)后,透明敷料不同更换频率对导管感染发生的影响,为透明敷料选取合适的更换频率提供理论依据。方法选取2012年6月-2015年6月在医院接受留置PICC导管的450例新生儿为研究对象,按照随机的方式将其平均分成3组,其中Ⅰ组每3d更换一次敷料,Ⅱ组每5d更换一次敷料,Ⅲ组每7d更换一次敷料,分析比较3组新生儿导管相关感染的发生。结果 450例新生儿中共有21例发生导管口感染,感染率为4.67%;3组新生儿病原菌检出均以表皮葡萄球菌最多,分别占57.14%、71.42%、49.99%,其次为肺炎克雷伯菌,分别占42.86%、14.29%、16.67%;发生导管相关的血液感染,Ⅰ、Ⅱ组感染率均为0.67%,Ⅲ组未发生导管相关的血流感染。结论建议新生儿中心静脉导管的敷料更换频率为每7天1次,减少医护人员的工作量,降低医院感染率,敷料出现潮湿、松动等现象时,应及时更换。
[Abstract]:Objective To investigate the effect of different frequency of transparent dressing on catheter infection after peripherally inserted central catheter (PICC) in neonates, and to provide theoretical basis for selecting appropriate frequency of transparent dressing. The incidence of catheter-related infection was analyzed and compared among the three groups. Results 21 cases of catheter-related infection occurred in 450 neonates, the infection rate was 4.67%. Staphylococcus epidermidis accounted for 57.14%, 71.42%, 49.99% respectively, followed by Klebsiella pneumoniae, 42.86%, 14.29%, 16.67% respectively; catheter-related blood infections occurred in group I and II, the infection rate was 0.67%, and no catheter-related bloodstream infections occurred in group III. Conclusion It is suggested that the dressing frequency of central venous catheter should be changed once every 7 days. It is necessary to change the dressing in time when the workload of medical staff is reduced, the nosocomial infection rate is reduced, and the dressing is wet and loose.
