The bacteriemia of hospital period after cardio-surgical operations

Abstract

The study was carried out to determine specter of agents of bacteriemia and their sensitivity to antibiotics in patients after cardiosurgery operations during hospital period. The analysis of bacteriemia after 850 cardiosurgery operations of 2013 was implemented. The agents of bacteriemia were identified using panels BD Crystal and database BBL Crystal MIND. The sensitivity of microorganisms to antibiotics was determined using disk-diffusion test according standards NCCLS. During monitored period after cardiosurgery operations occurrence of bacteriemia was established in 8.4% (71 out of 850 patients). The Gram-positive microflora with dominance of methicillin-resistant and coagulase-negative staphylococci prevailed in specter of microflora of hemocultures of patients of profile departments. In patients of reanimation and intensive therapy department sixfold increasing of amount of non-fermentative Gram-negative bacteria with prevalence of acinetobacters was marked. The poly-resistance of main agents of bacteriemia to antibiotics, including non-fermentative Gram-negative bacteria to carbapenems, was noted. In deceased patients, acinetobacters dominated under prevalence of Gram-negative agents in hemocultures.
