MEDELL GAGO, Manuel; HART CASARES, Marcia  e  MORA DIAZ, Isabel. Acinetobacter baumannii versus Pseudomonas aeruginosa. Behavior in mechanically-ventilated patients. Rev cubana med [online]. 2012, vol.51, n.3, pp. 239-246. ISSN 0034-7523.

Both Acinetobacter baumannii and Pseudomonas aeruginosa are considered to be causal agents of severe lower respiratory tract infections in patients under mechanical ventilation in intensive care units. A descriptive cross-sectional study was conducted with 36 mechanically ventilated patients from intensive care units to compare the importance of the two species. The most relevant results showed that of 20 patients with A. baumannii, 15 (75.00 %) developed ventilator-associated pneumonia, and 10 (50.00 %) died with sepsis vs. 13 (100 %) patients with Ps. aeruginosa, of whom 12 (92.30 %) developed ventilator-associated pneumonia and 4 (30.76 %) died with sepsis. It is concluded that of the two microbial species, Acinetobacter baumannii was found in most patients with ventilator-associated pneumonia and in those for whom sepsis played a significant role as a cause of death.
