PEREZ MORALES, Ledys et al. Clinical, Epidemiological and Microbiological Study of Patients Admitted to Intensive Care Units with Mechanical Ventilation Related Pneumonia. Medisur [online]. 2012, vol.10, n.4, pp. 268-278. ISSN 1727-897X.

Background: Mechanical ventilation related pneumonia is a very current issue due to its frequency, severity and etiologic and therapeutic implications. Objective: To characterize, from a clinical, epidemiological and microbiological point of view, patients with ventilation related pneumonia who are admitted to intensive care units. Methods: Descriptive case series study, conducted from January 2007 to December 2009, at the Laboratory of Microbiology and intensive care units of the Dr. Gustavo Aldereguía Lima General Hospital in Cienfuegos.  We analyzed the following variables: service that remitted patients, age, sex, cause of admission to intensive care unit, discharge status, microbiological results, isolated microorganisms, antimicrobial disks tested and antimicrobial resistance in vitro. Results: mechanical ventilation related pneumonia in intensive care units was observed mainly in male patients over 65 years old (43.1%) with multiple trauma (20.9%); 20.9% were patients with cerebrovascular disease. Acinetobacter baumannii was the most frequently isolated organism in all units (41.4%), except in the Surgical Intensive Care Unit. It also reported a high mortality rate and in vitro resistance to all antimicrobials tested. Conclusions: Acinetobacter baumannii was the most isolated germen in cases of mechanical ventilation related pneumonia in intensive care units` patients. It affected mainly patients with multiple trauma and cerebrovascular disease.
