【摘要】：目的探讨早产儿最佳经外周静脉置入中心静脉(PICC)透明敷料更换频率,为降低早产儿PICC导管相关性感染提供依据。方法将2014年8月-2015年10月新生儿科PICC置管的早产儿129例,采用随机对照法将其分为两组,实验组63例,对照组66例;置管后次日两组患儿均常规更换敷料1次,以后根据分组情况,对照组7天更换一次;实验组按需更换;比较两种透明敷料更换频率对早产儿PICC导管相关性感染的影响,包括导管相关性血流感染(CRBSI)、穿刺口部位感染、导管病原菌定植。结果实验组CRBSI发生率与穿刺口部位感染率均低于对照组(P0.05),虽然两组导管病原菌定植种类数差异无统计学意义,但总病原菌定植数差异有统计学意义(P0.05)。结论早产儿PICC置管后敷料按需更换比3天、5天、7天更换一次更安全、更有效;按需更换敷料对血流感染有保护作用,延长PICC留置的时间。
[Abstract]:Objective to investigate the frequency of replacement of transparent dressing for preterm infants by placing central vein through peripheral vein. Methods from August 2014 to October 2015, 129 premature infants with pediatric PICC catheter-related infection were treated. They were randomly divided into two groups: experimental group (n = 63) and control group (n = 66). The next day after tube placement, the two groups of children routinely changed dressing once, then according to the grouping situation, the control group changed once every 7 days. The experimental group was replaced as needed; To compare the effect of two kinds of transparent dressing replacement frequency on PICC catheter-related infection in premature infants, including catheter-associated blood flow infection and puncture orifice infection. Results the incidence of CRBSI and the infection rate of puncture site in the experimental group were lower than those in the control group (P 0.05), although there was no significant difference between the two groups. Conclusion it is safer and more effective to replace the dressing after PICC tube placement in premature infants than in 3 days and 5 days and 7 days. Changing dressing as needed protects against blood flow infection and prolongs the retention time of PICC.
