Frequency of isolation of nosocomial pneumonia pathogens from the respiratory tract of cardiac surgery hospital patients who are under extended artificial lung ventilation and efficiency of oral cavity sanitation with chlorhexidine solution

Objective. To assess the frequency and degree of bacterial contamination respiratory tract in patients cardiac surgery hospital, who are on prolonged mechanical ventilation, to evaluate efficiency sanitation oral cavity with a solution chlorhexidine.
 Materials methods. A comparative analysis tracheobronchial microbiota operated hospital undergoing (4872 hours) artificial lung ventilation (ALV) was carried out. Microbiological assessment effectiveness sanation 0.1 % aqueous chlorhexidine is given.
 Results. The ALV represented by gram-positive (S. epidermidis) gram-negative (K. pneumoniae, P. aeruginosa, A. baumannii) microorganisms as well Candida fungi. It found out that indices intensity microbial isolation from samples lower parts content were comparable those cavity. exception S. epidermidis, number which airways compared upper ones low. There statistically significant decrease after procedure an solution.
 Conclusions. Frequency opportunistic inaumannii, fungi) surgical under have no differences. whose numbers low ones. microbiological process has been established.
