ABSTRACT

Introduction: there are clinical variables at the beginning of the ventilation that are proper of the ventilatory treatment and the complications associated with mortality.
Objective: to identify and quantify the influence of different factors hypothetically related to the evolution of the patients, the prognosis of patients with artificial mechanical ventilation.
Method: a cohort study was designed in the Intensive Care Unit of the University General Hospital "Carlos Manuel de Cespedes" of Bayamo, Granma, Cuba, since June 1st of 2013 to December 31, 2014. There were included 96 patients ventilated for more than 48 hours. Death was considered as a variable marker of prognosis.
Results: the risk of dying increased after 53 years (RR 2.3, 95% CI 1.0 to 5.4) was almost 5 times higher because of the crash (RR 4.5, 95% CI 1,8 11.1); it was tripled in the presence of comorbidities (RR 2.5, 95% CI 1.0 to 5.9) and 2-4 organ failure (RR 3.4, 95% CI 1.4 to 8.2). Other prognostic factors were the Fi02 › 47 (RR 23.4, 95% CI 7.6 to 71.3, p = 0.00), acidosis (RR 95% CI 4.1 to 46.7 14), the pneumonia associated to ventilation (RR 3.6, 95% CI 1.3 to 9.5) and the use of inotropes (RR 2.5, 95% CI 1.0 to 2.9). Among them, the FiO2, acidosis and pneumonia associated with mechanical ventilation had an independent relationship with death.
Conclusions: FiO2, acidosis and pneumonia associated with mechanical ventilation are the prognostic factors in patients with invasive mechanical ventilation.
