ABSTRACT

Background: The development of acute respiratory syndrome (ARDS) increase mortality. Prone position now is part of treatment of this problem. Objective: To evaluate gas exchange and hemodynamics in patient with ARDS before, during and after the change from supine to prone position. Design: Prospective, nonrandomized interventional study. Patient and methods: Five patients with ARDS and important alterations in gas exchange were included in the study. Gas exchage measurements were performed at the following time points: baseline supine; after one hour of prone position, after twelve hours of prone position and two hours after return to supine position. Results: After one hour in prone position an increase of PaO2, PaO2/FIO2 and arterial saturation of oxygen (SaO2), with decrease of intrapulmonary shunts (Qsp/Qt) was observed. Conclusion: Prone position improvement gas exchange in patient with ARS, without changes in hemodynamics.
