Abstract:
Objective To analyze risk factors of Swan-Ganz catheter-related bloodstream infections ( CRBSI) in patients with severe heart disease in Cardiac Care Unit ( CCU) . Methods A total of 768 patients undergoing indwelling Swan-Ganz catheterization in CCU between January 2013 to December 2014 were enrolled in this study. Bacterial culture of blood in catheter and catheter tip that 5 cm distance from distal end were performed if the patients were suspected of intravascular catheter-related infections or the catheter was removed from the patients for more than 7 days. Results During 3050 catheter days, 23 of 768 patients were diagnosed of CRBSI(7. 5 ‰), and the infection rate was about 3%. The top 5 pathogenic bacteria were staphylococcus aureus, staphylococcus haemolyticus, staphylococcus epidermidis, albicans saccharomyces and klebsiella pneumoniae. The patient′s gender, ages, with diabetes or not, and usage of antibiotic during catheterization had no correlation with catheter related infection (P >0. 05), but the skin of whole body clean or not before catheterization, the length of catheterization had correlation with catheter related infection ( P < 0. 05 ). Multivariate logistic regression analysis showed that the whole bode skin clean before catheterization was the protective factor for CRBSI, and long catheter indwelling time and combined antibiotic treatment during catheterization were the risk factors for CRBSI (P<0. 05). Conclusions The incidence of CRBSI in patients with severe heart disease is related to the catheter indwelling time, and skin clean before indwelling which are able to effectively reduce the incidence of CRBSI. Antibiotic treatment during catheterization is not beneficial for decreasing the incidence of CRBSI.
