[Detected of associated contagious parameters of blood recipients before transfusion and their clinical significance].

Objective: To investigate the significance in prevention of nosocomial infection of the testing of the associated contagious parameters of blood recipients before transfusion.

Methods: A retrospective analysis was adopted, 44 968 pre-transfusion patients were tested the serum hepatitis B virus surface antigen (HBsAg), antibody against hepatitis C virus (anti-HCV), antibody against T. pallidum (anti-TP) and antibody against human immunodeficiency virus(anti-HIV).

Results: The total positive rate was 22.41%. Positive rate of HBsAg, anti-HCV and anti-TP were 20. 67% (9294/44 968) , 0.33% (148/ 44 968) and 1.65% (9741/44968), respectively; anti-HIV was positive in 39 patients, 23 cases coinfection of the other three indicators at least one positive in 39 cases of anti-HIV-positive blood recipients, of which was mostly observed T. pallidum; co-infection of HBV, HCV and/or TP were 117 cases, and were mostly observed between HBV and HCV, HCV and TP; for HBV infection the department of digestive medicine was prevalent(Chi2>or=83.0, P <0.01).

Conclusion: Part of blood recipients before admission had been infected with a contagious disease. The testing of the associated contagious parameters of blood recipients before transfusion is not only useful for both of the hospital and the patients, but also more important to ensure safe blood transfusion, decrease medial dissatisfaction and to prevent nosocomial infection.
