[Procedure in case of exposure of hospital's workers to HBV, HCV and HIV].

The aim of this study was to show our own experiences in the treatment our hospital's workers after the exposition of potentially infectious material. The register of the occupational exposition was established on 1st January 2001. 43 cases of occupational exposition to potentially infectious material were noted down, since the beginning of the observation to 31st October 2004. The persons who were injured, represented different professional groups: 9 physicians, 19 section nurses, 13 operative nurses and 3 maintenance workers. The exposition was caused by needle pricks during blood collection or injections (34 cases), as a result of a scalpel or other surgical instrument cut (2 cases), a splash of infectious material on the skin and conjunctivae (4 cases) and in the singular cases as a result of a bite by a stimulated patient, a medical waste cut in a rubbish bag or the hospital equipment. It was determined in the immunological examinations that among patients being the source of infection were: 1 person HBsAg(+), 5 persons anti-HCV(+), 37 persons HbsAg (-), 33 persons anti-HCV(-) and 5 persons HBsAg(?) and HCV(?). One medical unvaccinated worker was exposed to the HBsAg(+) blood. The specific treatment was administered by the application of 1 dose of anti-HBs immunoglobulin and realization of a series of protective vaccinations against HBV. 4 persons are being observed due to an exposition to HCV(+) blood. In all cases until now the treatment has been finished without a diagnosis of the occupational infection.
