Improve cleaning and disinfectant methods for subclavian vein catheteriza-tion dressing change / 中国感染控制杂志

ABSTRACT

Objective To evaluate the effect of improved cleaning and disinfection method for subclavian venipunc-ture dressing change to prevent catheter-associated infection. Methods 120 hospitalized patients with right subcla-vian venipuncture at an intensive care unit in January-June 2012 were divided into control group (n= 60)and experi-mental group(n= 60)according to venipuncture date. Control group adopted conventional dressing changedisin-fected skin at and around puncture point by 2% iodine tincture,then used 75% alcohol for deiodination;experimen-tal group adopted improved dressing changeWiped skin at and around puncture point three times by normal saline, cleaned catheter,disinfected skin around puncture point (avoid puncture point)three times by 75% alcohol,disin-fected skin at and around puncture point three times by 0 .5% iodine tincture ,then disinfected catheter . Associated infection rate between two groups were compared . Results Focal infection rate and CRBI rate of experimental group were both lower than control group(5.00% vs 16.67% ;1.67% vs 13.33% ),the difference was statistically different (P< 0.05 ). Conclusion Effect of improved dressing method is better than the conventional dressing method,it can effectively prevent occurrence of focal infection and CRBI.
