敷料不同时间更换对PICC导管穿刺部位感染的影响

The influence of dressing different time on PICC catheter puncture site infection

目的探讨敷料不同时间更换对外周置入中心静脉导管(peripherally inserted central catheter,PICC)穿刺部位感染的影响。方法选择2010年1月到2011年12月在该院行外周置入中心静脉导管的患者88例,按照敷料更换时间随机将患者分为3组,即1 d更换敷料组(A组)28例,3 d更换敷料组(B组)30例,5 d更换敷料组(C组)30例。观察3组感染发生情况。结果与A组患者感染率(7.4%)比较,B组患者感染率为(10.0%),差异无显著性,无统计学意义(P>0.05)。与A组患者和B组患者感染率(7.4%,10.0%)比较,C组患者感染率为23.3%,有明显增加,差异有统计学意义(P<0.05)。结论 1 d更换一次敷料明显降低PICC导管穿刺部位感染率,超过5 d则危险性增加,为临床操作提供科学依据。

Objective to investigate influence of dressing different time on the infection of periphery inserted central venous catheter（peripherally inserted central catheter,PICC） puncture site.Methods Chose 88 patients with peripherally inserted central catheter in our hospital from January 2010 to December 2011,and randomly divided the patients into three groups,according to the dressing change time,namely 1 d changed dressing group（group A） 28 cases,and 3 d replaced dressing group（group B） 30 cases,5 d replaced dressing group（group C） 30 cases.Observed infection situation of three groups.Results Compared to group A of patients with infection rate（7.4%）,group B infection rate was（10.0%）,with no significant difference and no statistical significance（P 0.05）.Compared to group A of patients with infection rate（7.4%） and group B with infection rate（10.0%）,group C infection rate was（23.3%）,significantly increased,with significant difference,there was statistically significant（P 0.05）.Conclusions The impact of replacing dressing 1d PICC catheter infection rate of puncture is obviously reduced,and replacing dressing more than 5 d is increased risk,and provides the scientific basis for clinical operation.
