About this study
Official title: Prone Position With Different Types of Cushions in Patients With Acute Respiratory Distress Syndrome - Effects on Mechanics, Oxygenation, and Electrical Impedance Tomography Imaging
The prone maneuver is a well-established therapy in ARDS. Traditionally, the maneuver is perform with thoraco-abdominal cushions. The goal of this study is assess, using electrical impedance tomography, whether the arrangement mode of the cushions alters lung recruitment during the prone maneuver in patients with moderate to severe ARDS.
Read the detailed description
The prone position is a ventilatory therapeutic strategy used in the treatment of patients with moderate to severe Acute Respiratory Distress Syndrome (ARDS) that promotes improved oxygenation with consequent reduction in mortality. Despite being safe and effective, it is not without complications, with pressure injuries being one of the main concerns. The use of cushions helps prevent such injuries, but they can interfere with ventilatory mechanics depending on where they are placed. The aim of this study is to assess whether there is a difference in ventilatory mechanics when performing the prone maneuver with a thoraco-abdominal cushion or a modified lateral cushion, based on measurements from electrical impedance tomography (EIT), gasometric data, and parameters of mechanical ventilation.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Prone position with thoraco-abdominal cushionProcedure or surgery
Prone position with cushions positioned laterally on the chest, abdomen, and pelvis
| Study group | Role | What they receive |
|---|---|---|
| Usual prone position | No intervention | Prone position with thoraco-abdominal support (cushions on the chest and hips, leaving the abdomen free) |
| Modified prone position | Experimental | Prone position with lateral support (lateral cushions on the chest, hips and abdomen) Receives: Procedure: Prone position with thoraco-abdominal cushion |
What is being measured
The primary outcome is the main question the study is designed to answer.
Lung recruitment
Change in ventilation of dorsal regions of lung (%) assessed by electrical impedance tomography
Measured: 1 hour before prone - 2 hours before supine
