RESUMO
The objective is to assess the influence of infections and the microbiological spectrum on the general outcome of patients undergoing therapy with extracorporeal devices (ECDs), extracorporeal membrane oxygenation, extracorporeal life support, and pumpless extracorporeal lung assist. We performed a single-center, retrospective analysis of 99 patients receiving ECD. Infections requiring ECD, nosocomial infections occurring during treatment, the use of guideline-based antiinfective therapies, and patient outcomes were described and statistically analyzed. We analyzed 88 patients-survivors and nonsurvivors-and subdivided the infections into primary and nosocomial infections. The median patient age was 54.0 years, 85.2% were men, and 45 (51.1%) survived. Surviving ECD patients had a higher risk of nosocomial infection because of their prolonged hospital stay. Our results indicated that early, focused, antiinfective therapy was important to avoid severe infection complications. Infections causing sepsis and multiorgan dysfunction were negatively associated with outcome and successful weaning of ECD. The percentages and types of pathogens in the ECD cohort did not differ from the general colonization of intensive care units. Because a significant correlation between pathogens, infections, and outcome was not detected, we recommend focusing on clinical parameters to decide whether patients will benefit from ECD support.
