目的:研究分析重症监护室(ICU)患者中心静脉导管感染的的危险因素,并提出相应的预防对策,为防治ICU导管感染提供一定的参考。方法:回顾性分析2014年1月-2015年6月间在ICU中心行静脉置管的726例患者,分析导管感染的发生率。采集导管感染患者的血液、痰液、脓性分泌物等进行细菌培养,分析导管感染的危险因素并提出相应的预防对策。结果:726例ICU中心静脉导管发生CRI共58例,感染发生率为7.99%。58例CRI患者均送检样本进行病原菌检验,均检出病原菌,阳性率为100.00%。结论:引起ICU导管感染的病原菌以葡萄球菌为首位,高龄、ICU类别、导管留置天数是感染发生的高危因素。严格的无菌操作、缩短置管时间、合理应用抗菌药物对防止ICU患者发生导管感染具有积极的临床意义。
Objective: To study the risk factors of central venous catheter infection in intensive care unit (ICU) patients and to put forward corresponding preventive measures to provide some reference for the prevention and treatment of ICU catheter infection. Methods: A retrospective analysis of 726 patients with venous catheters in the center of ICU from January 2014 to June 2015 was conducted to analyze the incidence of catheter infection. Collecting blood, sputum and purulent secretions of patients with catheter infection for bacterial culture, analyzing the risk factors of catheter infection and putting forward corresponding preventive measures. Results: There were 58 CRI cases in 726 ICU central venous catheters, the incidence of infection was 7.99%. 58 cases of CRI patients were sent to the test samples for pathogenic bacteria were detected pathogenic bacteria, the positive rate was 100.00%. Conclusion: Staphylococcus aureus is the most common pathogen causing catheter infection in ICU. The age, ICU type and catheter indwelling days are the risk factors of infection. Strict aseptic operation, shorten the time of catheterization, rational use of antimicrobial agents to prevent ICU patients with catheter infection has a positive clinical significance.
