【摘要】：目的探讨预冲式导管冲洗器对住院患儿医院感染的预防作用,为降低医院感染提供依据。方法选取2014年1-12月400例因肺炎住院患儿,将患儿随机分为试验组和对照组,每组各200例,试验组采用预冲式导管冲洗器冲封管,对照组采用普通注射器生理盐水脉冲式正压冲封管,比较两组患儿医院感染率、不良事件发生率,并分析医院感染病原菌分布;采用SPSS21.0软件进行统计分析。结果 400例患儿共有27例发生医院感染,医院感染率6.75%,其中试验组5例,感染率2.50%,对照组22例,感染率11.00%,试验组医院感染率显著低于对照组,差异有统计学意义(χ2=5.739,P0.05);27例感染患儿共分离出31株病原菌,其中革兰阳性菌20株占64.5%,革兰阴性菌8株占25.8%,真菌3株占9.7%;试验组导管内血栓形成率显著低于对照组(P0.05),两组间局部渗血、意外脱管等不良事件发生率比较差异无统计学意义。结论静脉留置针改善血栓形成及不良事件发生优于传统方法,采用预冲式导管冲洗器能够显著降低住院患儿医院感染率。
[Abstract]:Objective to investigate the preventive effect of pre-punching catheter washing device on nosocomial infection in hospitalized children and to provide evidence for reducing nosocomial infection. Methods 400 hospitalized children with pneumonia from January to December 2014 were randomly divided into experimental group and control group with 200 cases in each group. In the control group, the nosocomial infection rate, the incidence of adverse events and the distribution of nosocomial infection pathogens were analyzed by SPSS21.0 software. Results there were 27 cases of nosocomial infection in 400 cases, and the nosocomial infection rate was 6.75%. Among them, 5 cases were in the experimental group, 2.50 cases in the control group, and 22 cases in the control group. The nosocomial infection rate in the experimental group was significantly lower than that in the control group. The difference was statistically significant (蠂 ~ 2 / 5.739 / P0.05A = 27 cases), among which 20 Gram-positive bacteria accounted for 64.5, 8 Gram-negative bacteria accounted for 25.8, and 3 fungi accounted for 9.7.The thrombus formation rate in the test group was significantly lower than that in the control group (P0.05), and local blood leakage was found between the two groups. There was no significant difference in the incidence of adverse events such as accidental extubation. Conclusion Venous indwelling needle is superior to the traditional method in improving thrombosis and adverse events, and the nosocomial infection rate of hospitalized children can be significantly reduced by using preflushing catheter flushing device.
