Prone position ventilation is frequently used in the ICU to treat severe hypoxemia in patients with COVID-19 associated acute respiratory distress syndrome (ARDS). The aim of the PROVENT-COVID study is to assess whether applying prone position ventilation immediately after intubation reduces the duration of mechanical ventilation compared to prone position ventilation according to standard criteria for prone position.
In patients with COVID-19 the incidence of ARDS is 15% and the all-cause mortality 4%. No treatment has been shown to improve the outcome of these patients.
Mechanical ventilation in the prone position decreases mortality with around 50% when applied to patients with severe respiratory failure. Applying prone position earlier in patients with COVID-19 could have several benefits, but may also carry significant side-effects and an increased workload for the health-care personnel. It is urgently needed to assess whether this potential life-saving intervention is effective.
The aim of the PROVENT-COVID is to determine whether prone position ventilation, initiated immediately after intubation, lead to more days alive without respiratory support compared to prone position initiated according to standard indication in patients with COVID-19 associated respiratory failure.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Accelerated prone position | Experimental | Prone position ventilation initiated as soon as possible following intubation. The patients are maintained in a prone position for 12-16 hrs daily for 5 days, unless one of the following criteria are met: Substantial improvement and/or imminent extubation, Worsening oxygenation with prone position, Serious Adverse Reactions (SARs) occurring during a prone session and leading to its immediate interruption. Following the five day intervention period, prone position ventilation will be continued according to the intervention in the control group |
|
| Standard prone position | Active Comparator | Standard of care: Prone position applied according to standard indications (severe ARDS not improving with 12-24 hours of mechanical ventilation with PaO2-to-FiO2 ratio (PAF) < 150 mmHg with FiO2 of ≥0.6, a positive end-expiratory pressure (PEEP) of ≥5 cm of water, and a tidal volume of about 6 ml per kilogram of predicted body weight). Until one of the following are met: Substantial improvement and/or imminent extubation, Worsening oxygenation with prone position, Serious Adverse Reactions (SARs) occurring during a prone session and leading to its immediate interruption. |
