敷料更换的不同次数对穿刺引流术后穿刺口感染的影响

目的 研究敷料更换的不同次数对穿刺引流术后穿刺口感染的影响.方法 随机将该院2013年6月—2014年7月收治的100位进行穿刺引流术的患者分为两组,50例为A组,50例为B组. 为A组患者1周更换1次敷料,B组患者1周更换2次敷料. 对两组患者穿刺口感染的情况进行分析比较. 结果 A组患者穿刺口感染的几率显著低于B组(P<0.05),A组患者的病原菌定植率显著低于B组(P<0.05),两组患者导管相关性血流感染率差异无统计学意义(P>0.05). 结论 穿刺引流术后的患者1周更换1次敷料比较合理,既能降低患者术后穿刺口感染的几率,又能降低医护人员的工作量,但要注意在敷料发生松动或者潮湿时也要及时进行更换.

Effects of Frequency of Change of Dressing on the Puncture Site Infection after Puncture Drainage Surgery

Objective To explore the effects of frequency of change of dressing on the puncture site infection after puncture drainage surgery. Methods 100 patients underwent puncture drainage surgery in our hospital from June 2013 to July 2014 were randomly divided into group A and group B, with 50 patients in each group. The dressing was changed once a week in group A while that was changed twice a week in group B. And the puncture site infection of the two groups were analyzed and compared. Results The incidence of puncture site infection in group A was significantly lower than that in group B(P<0.05). The pathogenic bacteria colonization rate in group A was significantly lower than that in group B(P<0.05). There was no sig-nificant difference in the rate of catheter-related bloodstream infection between the two groups(P>0.05). Conclusion Chang-ing the dressing once a week is reasonable, for it can not only effectively reduce the incidence of puncture site infection af-ter puncture drainage surgery, but also reduce the workload of nursing staff. However, the dressing should be changed time-ly when it is loose or wet.
