摘　　要：目的对ICU中心静脉导管患者发生医院血性感染的相关情况进行分析,探讨发生特点和危险因素。方法对785例ICU中心静脉置管患者的一般情况和临床资料进行回顾性分析,包括患者的年龄、性别、自理能力、自身免疫性疾病、置管时间、置管部位和免疫抑制剂的使用等相关性感染因素。结果 785例患者相关血性感染共发生34例,发生率4.3%。34例病原菌共检出29株,阳性率85.3%。检出以革兰氏阴性菌为主,占总检出的48.3%,其次为革兰氏阳性菌,占41.4%,再次为真菌,占10.3%。ICU中心静脉导管患者发生医院血性感染与年龄、自理能力、自身免疫性疾病、置管时间和免疫抑制剂的使用相关。结论积极治疗患者自身免疫性疾病,对置管时间进行控制,并减少免疫抑制剂的使用,是减少ICU中心静脉导管相关血性感染的重要措施。Objective To investigate the bloodstream infection in patients with central venous catheter in ICU,explore the risk factors.Methods Totally 785 patients with central venous catheter were chosen and studied to analyze the risk factors which might cause bloodstream infection.The correlation factors were gender,age,self-help skills,autosomal disease,insertion time,catheter site,and application of immunosuppressive.Results 34 cases catheter-related bloodstream infection cases were detected in ICU（4.3%）.29 cases were detected in 34 cases of pathogens,with the positive rate of 85.3%.The most common bacteria were Gram-negative bacteria,accounting for 48.3%,followed by Gram-positive bacteria which accounting for 41.4%,and Fungi which accounting for 10.3%.The analysis of 785 cases showed that the infection rate was closely related to age,self-help skills,autosomal disease,insertion time,and application of immunosuppressive.Conclusion It was effective to reduce the infection by treating the autosomal disease positively,controlling insertion time and using immunosuppressive rationally.
