Abstract
Objective To investigate the correlation of blood ICU in elderly patients with central venous catheter infection (CRBSI) study on the etiology, analysis of drug resistance of the pathogenic bacteria, and evaluate the risk factors of infection and prevention measures. Method From June 2011 to June 2013, the clinical data of 300 patients in our hospital ICU tube central vein, the risk factors for the development of CRBSI, the pathogenic bacteria culture and drug resistance were analyzed retrospectively. Result 300 cases of ICU central venous catheters were CRBSI 38 cases (12.7%), wherein the subclavian vein catheterization in 120 cases, 9 cases of CRBSI (7.5%);the internal jugular vein catheterization in 105 cases, 12 cases of CRBSI (11.4%); femoral vein catheterization in 75 cases, 17 cases of CRBSI who (22.7%); femoral vein catheter infection rate was the highest, and subclavian and carotid stent comparison, the difference was statistically signiifcant (P<0.05). A total of 38 cases of pathogenic bacteria in 46 cases, in which G+bacteria accounted for 29 cases (0.63%), G-bacteria accounted for 13 cases (28.3%), 4 cases of fungus (8.7%);CRBSI pathogen in epidermal staphylococcal and Bauman Acinetobacter, where G+drug resistance of bacteria to vancomycin 0, while the G -bacteria were most sensitive to imipenem. Infection and the indwelling time of indwelling position,>15 days, diabetes, age>70 years old, and mechanical ventilation and so on (P<0.05), gender is not associated with infection (P>0.05). Conclusion ICU center in elderly patients with venous catheter related bloodstream infection is easy to occur, clinical staff should strengthen the concept of aseptic operation, reduce the risk as far as possible, early to the prevention and control measures, to reduce the infection rate.关键词
