BACKGROUND:Acute respiratory distress syndrome (ARDS) is a type of hypoxic respiratory failure that RESULTS: To determine if the use of inhaled epoprostenol produced a 10% or greater increase in the ratio of arterial partial pressure of oxygen (PaO2) to fraction of inspired oxygen (FiO2) in ARDS patients and to review adverse events and medication errors.METHODS:An observational chart review was performed based on a report generated from the electronic medical record system. Patients who received at least 1 dose of inhaled epoprostenol from January 1, 2008, to December 31, 2010, at any hospital within the Florida Hospital Health System were considered for inclusion. Demographics, dose, duration of therapy, adverse effects, medication errors, and outcomes data were collected.RESULTS:Sixteen patients were included in the study. Oxygenation improved by 10% or more in 62.5% (10/16) of the patients, with an initial (within the first 4 hours) median increase of 44.5% in PaO2/FiO2. The mean (SD) starting dose was 30 (10) ng/kg/min. Medication errors were observed in 25% (4/16) of patients. Hypotension was the most frequently observed adverse event, with a rate of 18.8% (3/16).CONCLUSIONS:Based on study findings, inhaled epoprostenol may improve oxygenation in patients with ARDS, with findings suggesting a 62.5% response to therapy. The significance of these effects on improving survival remains unknown. The frequency of medication errors observed in this study poses a significant concern regarding the administration of epoprostenol. Further controlled prospective studies are needed to determine the role of inhaled epoprostenol in improving survival in patients with ARDS.
