균혈증이 동반된 중증 지역사회 획득 Acinetobacter baumannii 폐렴 1예

Acinetobacter baumannii is a significant pathogen in nosocomial infections, especially in intensive care units. However, community-acquired A. baumannii (CAAB) pneumonia is an uncommon disease. Most of the CAAB pneumonia in the literature is characterized by an abrupt onset and rapid progression to respiratory failure and hemodynamic instability. In our case, a 51-year-old man without underlying diseases developed severe pneumonia. Respiratory distress rapidly worsened and mechanical ventilation was applied. Extra-corporeal membrane oxygenation was applied due to refractory septic shock. Fully sensitive A. baumannii pneumonia was confirmed by the sputum culture and blood culture. The patient was effectively treated by the meropenem. However, the patient died of uncontrolled ventilatorassociated pneumonia, developed on the 10th hospital day, and refractory septic shock. We report the case of severe CAAB pneumonia with bacteremia in a patient without underlying diseases in Korea. KCI Citation Count: 2
