【摘要】：目的了解重症医学科病房深静脉、动脉插管患者采用最大化无菌屏障,对预防导管相关血流感染(CRBSI)的作用。方法 2011年9月—2014年4月回顾性收集北京友谊医院重症医学科深静脉、动脉插管患者996例,根据患者是否实行最大化无菌屏障,分为标准无菌屏障组(SSB组,2011年9月—2012年12月,560人次)和最大化无菌屏障组(MSB组,2013年1月—2014年4月,436人次),比较两组患者CRBSI发生情况、病死率等。结果 SSB和MSB组患者插管部位构成比较,差异无统计学意义(χ~2=6.750,P=0.08)。SSB组CRBSI发生率为2.41‰(1.64‰~4.02‰),MSB组为1.91‰(0‰~4.56‰),经秩和检验比较,差异无统计学意义(Z=-0.057,P0.05);SSB组发生CRBSI 24例(4.29%),MSB组发生CRBSI 26例(5.96%),两组比较,差异无统计学意义(χ~2=1.447,P0.05)。SSB组病死率为(18.43±5.53)%,MSB组病死率为(11.68±4.14)%,经独立样本t检验,差异有统计学意义(t=3.907,P0.05)。结论最大化无菌屏障未减少CRBSI的发生。
[Abstract]:Objective to understand the ICU ward deep vein, artery intubation with maximum sterile barrier for the prevention of catheter-related bloodstream infection (CRBSI). Methods from September 2011 to April 2014 the ICU of Beijing Friendship Hospital were retrospectively collected 996 cases of deep vein, artery intubation patients, according to patients whether the maximum sterile barrier, divided into standard sterile barrier group (SSB group, September 2011 - December 2012, 560 times) and maximum sterile barrier group (MSB group, January 2013 - April 2014, 436 passengers), compared two groups of patients with CRBSI has the situation, the fatality rate. Comparison results of SSB and MSB groups of patients with intubation site, there was no statistically significant difference (x ~2=6.750, P=0.08.SSB) the CRBSI incidence rate was 2.41 per thousand (1.64 per thousand ~4.02%), MSB group was 1.91 per thousand (0 per 1000% ~4.56), by rank sum test, the difference was not statistically significant (Z=-0.057, P0.05); group SSB CRBSI 24 (4.29% cases), MSB group CRBSI 26 cases (5.96%), the two groups, the difference was not statistically significant (~2=1.447, P0.05).SSB mortality rate was (18.43 + 5.53)%, case fatality rate of MSB group was (11.68 + 4.14)%, with independent sample t test, the difference was statistically significant (t=3.907, P0.05). Conclusion the maximum sterile barrier did not reduce the incidence of CRBSI.
