[Intraoperative bacteriological examination of patients operated on under extracorporeal circulation]

Results of bacteriological examination of 41 patients during surgical operations on the heart under conditions of artificial blood circulation are presented. The frequency of contamination of intraoperative++ samples and species composition of the isolated microflora were analyzed. It was shown that representatives of nonfermenting gram-negative++ bacteria isolated during the operations and characterized by high antibiotic resistance could be the agents causing purulent septic complications in the patients during the postoperative period. It is concluded that intraoperative++ bacteriological examination of cardiosurgical patients with successive investigation of several samples from the pericardium before and after perfusion, as well as specimens of perfusion blood at various stages and resected heart valves is advisable.
