Study hypothesis
The aim of the present study was to investigate whether the evolution of Intra-Abdominal Pressure (IAP), liver function assessed by the Plasma Disappearance Rate of Indocyanine Green (PDRICG) and extravascular lung water is related to the type of support during PP. We therefore prospectively compared, in a population of medical-Acute Respiratory Distress Syndrome (ARDS) patients, the effects of an air-cushioned mattress and a conventional foam mattress during PP.

Condition
Acute Respiratory Distress Syndrome (ARDS)
Intervention
Baseline measurements were performed in the supine position after one hour of steady-state conventional mechanical ventilation. Then the following two periods of PP were randomised:
1. 6 hours of PP on the moulded foam mattress
2. 6 hours of PP on the air-cushioned mattress
A period of 18 hours in the supine position separated the two periods in the prone position. Each patient was his or her own control. Measurements were achieved in the supine position, after 1 and 6 hours of PP.

Eligibility
Participant inclusion criteria
Twenty consecutive patients with ARDS were included and turned prone in the medical intensive care unit of Sainte Marguerite University Hospital in Marseille, France. Patients were prospectively included in this study after obtaining written informed consent from the next of kin. The study design was approved by the Comité Consultatif de Protection des Personnes dans la Recherche Biomédicale of Marseille. ARDS was defined in accordance with the recommendations of the American/European Consensus Conference.
