摘要
目的探讨老年ICU中心静脉导管相关性感染(CRI)的发生率及其相关危险因素。方法回顾性分析行中心静脉插管的66例患者CRI的发生率,同时对患者CRI可能相关的25个因素进行多因素logistic回归分析,寻找与CRI相关的危险因素。结果 66例患者插管143次,共发生CRI 46例次,CRI发生率为32.17%、千导管日感染率为28.57‰;丧失自理能力、置入三腔导管为发生老年内科ICU患者CRI的危险因素(OR值分别为3.066、1.778)。结论老年内科ICU患者CRI的发生率高,而丧失自理能力、置入三腔导管者更易于发生CRI,尽量避免不必要的三腔静脉导管的留置、严格无菌操作和加强护理是降低该人群CRI发生率的关键。
OBJECTIVE To investigate the incident rate of central venous catheters related infection （CRI） in the geriatric internal intensive care unit and the related risk factors. METHODS The incident rate of CRI of 66 patients admitted to geriatric internal intensive care unit with venous catheter was calculated. And twenty-five possible CRI-related factors were analyzed with multivariate Logistic regression. RESULTS A total of 143 venous catheters were inserted to central venous of 66 patients admitted to the geriatric internal intensive care unit. The total incidence rate of CRI was 32.17~~, the day infection rate was 28.57%0. And the loss of self-care ability and the catheter with three lumens were two independent risk factor of CRI in elder patients with critical illnesses （odd ratio equals to 3. 066 and ]. 778 respectively）. CONCLUSION The incidence rate of CRI in geriatric internal intensive care unit is high. The elder patients who lost the ability of self-care and with three-lumen catheter is vulnerable to CRI. Preventing the unnecessary plantation of catheter with 3 lumens and strictly keeping the rules of sterile operation and improving nursing work are the key measures to reduce the incident rate of CRI in elder patients.
