Introduction:

pneumonia associated with mechanical ventilation has a high incidence and mortality in intensive care units.

Objective:

to characterize patients with mechanical ventilation admitted the Intensive Care Unit No. 2 at Abel Santamaría General Teaching Hospital during 2018.

Methods:

a descriptive, observational and cross-sectional study was conducted in patients with a diagnosis of pneumonia associated with mechanical ventilation. The target group consisted of 92, working with the totality of them. Chi Square and Odds Ratio tests were used, as well as the distribution by absolute frequency and relative percentage.

Results:

a predominance of male patients (54,35 %) was found, age group 70 to 79 years old (32,60 %) and diagnosis on admission of cerebrovascular disease (36,96 %). Pneumonia associated with prolonged mechanical ventilation represented 76,08 % and Gram-negative germs 86,96 %, patients with Enterobacter.sp (47,83 %) predominating. Mechanical ventilation of more than 14 days represented 58,7 %. Patients older than 70 years old (OR=10,8) and those with mechanical ventilation of more than 14 days (OR=2,93) had a higher risk of death.

Conclusions:

cerebrovascular diseases were common as a diagnosis at admission. Infection with Gram-negative germs developed during a prolonged mechanical ventilation process was common. Ages over 70 years and prolonged mechanical ventilation were risk factors for mortality.
