Conditions

Other: Prone decubitus
Registration Number

Lead Sponsor
University Hospital, Tours
Brief Summary

Acute Respiratory Distress Syndrome (ARDS) induces high mortality, particularly in the context of COVID-19 disease. Preliminary data from patients with ARDS related to COVID-19 disease appear to show significant effectiveness of prone positioning in intubated patients in terms of oxygenation as well as nasal high flow therapy before intubation. It should be noted that in Jiangsu province, secondarily affected, nasal high flow combined with the prone position was successfully integrated into care protocols.

The investigators hypothesize that the combined application of nasal high flow and prone positioning can significantly improve the outcome of patients suffering from COVID-19 pneumonia by reducing the need for tracheal intubation and associated therapeutics such as sedation and paralysis, resulting in both individual and collective benefits in terms of use of scarce critical care resources.

Detailed Description

Acute Respiratory Distress Syndrome (ARDS) induces high mortality, particularly in the context of COVID-19 disease. In patients with ARDS who are mechanically ventilated invasively through a tracheal tube and with a PaO2/FiO2 ratio (arterial oxygen partial pressure to inspired oxygen fraction ratio) of less than 150 mmHg, prone positioning significantly reduced mortality. Furthermore, nasal high flow, a non-invasive respiratory support and oxygenation technique, reduced the need for tracheal intubation and reduced mortality among the most severe patients (PaO2/FiO2 ratio less than 200 mmHg) suffering from acute hypoxemic respiratory failure. Prone positioning of ARDS patients treated with nasal high-flow was evaluated in 20 patients with predominantly viral pneumonia. The prone positioning was found to be feasible and associated with an increased PaO2/FiO2 ratio. Preliminary data from patients with ARDS related to COVID-19 disease appear to show a significant effect of prone positioning in intubated patients in terms of oxygenation improvement as well as nasal high-high flow appears effective in non-intubated patients. For instance, nearly half intensive care unit patients described in the princeps cohort in Wuhan City, Hubei Province, China, had received nasal high-flow. It should be noted that in Jiangsu province, secondarily affected, nasal high-flow combined with prone positioning was successfully integrated into care protocols.

Investigators hypothesize that the combined application of nasal high-flow and prone positioning can significantly improve the outcome of patients suffering from COVID-19 pneumonia by reducing the need for intubation and associated therapeutics such as sedation and paralysis, resulting in both individual and collective benefits in terms of use of scarce critical care resources.

Primary Outcome Measures
NameTimeMethod
Therapeutic failure within 14 days of randomizationFrom randomization to day 14

Therapeutic failure is defined by death or intubation or use of non-invasive ventilation at two pressure levels.

Secondary Outcome Measures
NameTimeMethod
Days spent in the intensive care unit and in the hospitalFrom randomization to day 28
Therapeutic failure within 28 days of randomizationFrom randomization to day 28

Therapeutic failure is defined by death or intubation or use of non-invasive ventilation at two pressure levels.

Timeframe of therapeutic escalation (in case of non-invasive ventilation at two pressure levels)From randomization to day 28
Evolution of the World Health Organization disease severity score of COVIDFrom randomization to day 28

Score reaches from 1 to 7, 7 indicates worse outcome

Evolution of oxygenation (PaO2/FiO2 ratio or SpO2/FiO2 surrogate) over the 14 days following randomizationFrom randomization to day 14
Patient comfort before, during and after the first prone position sessionFrom randomization to day 1

Comfort evaluted by the patient through a visual analogical scale

Evolution of the SpO2/FiO2 ratio during the first prone sessionFrom randomization to day 1
Evolution of the ROX index during the first prone sessionFrom randomization to day 1

ROX index is the ratio of pulse oximetry (SpO2)/fraction of inspired oxygen (FiO2) to respiratory rate.
