Prone Position in Patients on High-flow Nasal Oxygen Therapy for COVID-19 (HIGH-PRONE-COVID-19)

COVID-19 Clinical Trial

Official title: Evaluation of Prone Position in Conscious Patients on Nasal High-flow Oxygen Therapy for COVID-19 Disease Induced Acute Respiratory Distress Syndrome

Status Completed

Clinical Trial 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.

Clinical Trial 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.
