ABSTRACT

Introduction: Acute Respiratory Distress Syndrome (ARDS) is relatively frequent in intensive care.
Objective: To characterize the patients who presented ARDS in the intensive care unit at Enrique Cabrera Hospital in the period of time between March 2012-2014.
Method: A descriptive observational and prospective study in 101 patients with ARDS was performed. The quantitative variables resulted by mean arithmetic and standard deviation and by minimal and maximum values. The qualitative variables were offered in percentage. Statistically significant differences between the categories of some of the studied variables were identified by contingency tables and the statistical test value (X2) was obtained with a trusting interval of 95% (p=0.05).
Results: Pneumonia represented 56.4% of ARDS causes, the patients with mild ARDS were discharged alive in 85.7%; those patients who did not present complications were discharged alive in 91.7%. The complications were pneumonia associated to ventilation in 33%. The patients with APACHE II more than 19 points had a mortality of 76% and with mechanical ventilation more than 19 days a mortality of 83.3%.
Conclusions: The main ARDS cause was pneumonia. The medium value of PO2/FIO2 relation was 196.6 ± 69.9 and PEEP was 8.5 ± 3,3 cm H20. Patients with severe distress, who presented serious complications, three or more organs failure, APACHE II ≥ 20 points and ventilation for 20 or more days presented higher mortality.
