MATERIALS AND METHODS
All necessary ethical approvals for conducting the study have been obtained. This is a retrospective study, conducted in a tertiary cardiac hospital ICU’s with 30 beds. We evaluated patients who underwent adult cardiovascular surgeries during the period from March 2010 to February 2012. Cases were defined as new acquisitions of MDR-AB from specimen taken ≥48 hours following ICU admission, with clinical signs of infection. Data on the characteristics, laboratory results, applied treatments were collected from the electronic medical records and patients’ charts. The Hospital’s Infection Committee managed antibiotic treatment. Recorded data were as follows: age, gender, medical history, SOFA score on the day of infection diagnosis, type of surgery, postoperative days until infection, infection site, antibiotic susceptibility, complications (such as organ dysfunction, thrombocytopenia), days of mechanical ventilation after infection and length of CS-ICU stay.
