Abstract：Objective To explore the infectious pathogen and related factors of hospital acquired pneumonia in continuous renal replacement therapy ( CRRT ) and providing the basis for the development of nursing measures and intervention measures . Methods In order to analyze the incidence of nosocomial infections and pathogen and the related factors , this retrospective investigation collected the clinical data from 580 CRRT patients who were hospitalized to the center of hemodialysis units of our university from Sep .2009 to July.2014.Results The nosocomial infections were occurred in 58 cases of the 580 cases, and the infectious rate was 10.0%;the main pathogen was staphyloccocus aureus;the related factors (P<0.05) included age, therapy times, the basis of disease, dysphagia, the number of organ failure , disorder of consciousness , preventive application of antibiotics , and the risk factors included the age which is greater than or equal to sixty years (β=0.59, OR=3.79), therapy times which is greater than or equal to twenty four hours (β=1.12, OR=2.46), the basis of disease which is greater than or equal to twice types (β=2.79, OR=4.10), the number of organ failure (β=3.284, OR=12.70), disorder of consciousness which is holding (β=2.35, OR=3.26) and the protective factors including preventive application of antibiotics (β=-1.72, OR =0.18 ) were analyzed.Conclusion The hospital acquired pneumonia in CRRT patients is closely related to the number of factors .The appropriate intervention measures should be taken clinically to effectively control the occurrence of infections and enhance the treatment safety of patients .
