[Prevention of nosocomial infections at a cardiovascular surgery unit: therapeutic tactics, efficacy and results].

The experience of prevention of nosocomial infections inside a cardiovascular surgical unit leads to insist, among the various tactics, on the quality and the mode of disinfection of the operating room and the intensive care unit, in particular, the technics of air and surface processing (by Anios) of sterilizing water (by Hyconium B and Filtranios), of sterilized respirators (by Formobloc). Quality and efficiency are bacteriologically controlled. The good results, obtained for 3 years, testify of the efficiency of such technics. However some architectural and structural drawbacks can jeopardize a strict compliance towards prevention of nosocomial infections.
