摘要
目的回顾性分析危重病患者发生导管相关性感染(CRI)的因素。方法对近3年来ICU中351个留置深静脉导管病例的导管相关性感染发生率,插管时间、插管部位、导管腔数与感染发生率的相关性以及病原学等进行回顾性分析。结果锁骨下静脉CRI发生率13.68%>颈内静脉的5.32%,差异无统计学意义;以2周为周期分界点,股静脉、锁骨下静脉及颈内静脉CRI的各自前后比较,差异有统计学意义(P<0.05);单腔和双腔的CRI分别为10.30%和5.08%,差异无统计学意义。结论导管相关性感染的发生率与留置时间密切相关,留置2周后其发生率显著增加;但与年龄、性别、插管部位及导管腔数无关。
OBJECTIVE To retrospectively analyze the catheter-related infections （CRI） in critically ill patients. METHODS In the last three years, the data of 351 cases kept a deep venous catheter in ICU were analyzed, including the incidence of catheter-related infections, the infection rates associated with intubation time, intubation position, the number of catheter lumen. RESULTS The CRI rate of subclavian vein was higher than that of jugular vein, although with no statistical difference （P=0.05）; two weeks were taken as the cutoff point, the CRI of femoral vein, subclavian vein and jugular vein had respectively statistically significant differences （P〈0.05）, the overall of Which has highly significant statistical difference particularly（P〈0.01）. The CRI of single-chamber and dual-chamber have no significant differences （P〈0.05）. CONCLUSION The CRI rate is closely related with the retention time, which has a significant increase 2 weeks later, but not related to age, sex, intubation position and the number of catheter lumen and intubation number.
