Abstract:
Objective:To discuss what impact prone position ventilation (PPV) plays in treatment of acute respiratory distress syndrom (ARDS)originating from pulmonary disease(ARDSp) and extra-pulmonary disease(ARDSexp).Methods: Retrospective case-control cohorts study. Sixty patients with ARDS were included, were classified two groups which were originated from pulmonary disease(n=30) and extra-pulmonary disease(n=30), they were ventilated in PPV. And oxygenation of 0,2,4, and 6 hours in PPV, static compliance(Cst), airway resistance(Raw) of were evaluated. The Ultrasonic Cardiac Output Monitor was applied to monitor the cardiac function.Results:At 2 hours after ventilation in ARDSexp group, PaO2/FiO2 have been improved significantly. The longer duration of PPV seemed to be associated with continuous improvement and peaks at 4 hours. In ARDSexp group PaO2/FiO2 after ventilation at 3 hours exceeds the other groups. At 4 hours after ventilation, PaO2/FiO2 of both ARDSp and ARDSexp groups of PPV have been improved than that of supine position. After ventilation for 4 hours, the RAW of ARDSp decreases dramatically and considerably below the other groups.Conclusion: PPV was a safe and effective maneuver for improving oxygenation in patients with ARDSp and ARDSexp. Both ARDSp and ARDSexp clearly appear to benefit from PPV, particularly in ARDSexp group. PPV aslo influenced haemodynamics in patients rarely.
