Background: pnosocomial pneumonias are a health problem all over the world nowadays. In the intensive care units of hospitals, a great number of patients are admitted with requirements of mechanical artificial ventilation, risk factor associated to this kind of infections.Objective: to characterize the patients suffering from bacterial pneumonias associated to mechanical artificial ventilation admitted in the Intensive Care Unit (ICU) of “Dr. Ernesto Guevara de la Serna” Hospital during 2012.
Method: a descriptive and retrospective study was carried out in the 262 patients admitted in that unit from January to December, 2012. The sample consisted of 173 patients complicated with bacterial pneumonias. The data were collected from the patients’ health histories. The variables were age groups, radiological manifestations, most frequent germs and ventilatory modalities used.
Results: patients older than 60 years old prevailed in a 41 %, who were followed by the group of 50 to 59 years old, with a 26,5 %. The most frequent germ was the non-fermentative bacillus, in a 76,6 %. Volume control ventilator modality was the most used one, in 75 patients, for a 43,6 %. The hydro-mineral disorder was found in the 41 % of the cases, all of them with tendency to hypokalemia, which leaded to a difficult separation. The anatomic, clinic and radiological symptoms were the pneumonias related to disseminated focuses, with 95 patients, for a 54,9 %.
Conclusions: it was an achievement to characterize patients suffering from bacterial pneumonias associated to mechanical artificial ventilation.
