Prone Positioning Short-term Effects on Tissue Oxygen Saturation in Critical COVID-19 Patients (PRONECOVID19)
Short-term Effects of Prone Positioning on Tissue Oxygen Saturation, Measured by Near-infrared Spectroscopy, in COVID-19 Patients With Acute Respiratory Distress Syndrome
Study Overview
Status
Conditions
Detailed Description
After obtaining consent to participate in the study, the subjects included in the study will undergo a baseline 15-minute measurement of tissue oxygen saturation (StO2) measured non-invasively on the forearm by means of near-infrared spectroscopy (NIRS). Once a baseline stable StO2 value is obtained, a provocative test, consisting of a transient vascular occlusion, will be performed. The test will allow the obtention of a local metabolic rate, and a StO2 recovery rate after the ischemic stimulus.
Tissue oxygenation measurements will be performed in supine position, immediately before changing to prone positioning, and repeated after 20 minutes of stabilization, once in prone position.

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Change in tissue oxygenation (StO2)
Time Frame: 20 minutes
|
Tissue oxygenation is measured as percent of oxyhemoglobin over total hemoglobin content in the sensed area (skeletal muscle)
|
20 minutes
|
Change in local hemoglobin content (THC)
Time Frame: 20 minutes
|
THC is measured as microMols
|
20 minutes
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Compare changes in tissue oxygenation (StO2) and arterial oxygenation (SaO2)
Time Frame: 20 minutes
|
Arterial oxygenation (SaO2) is obtained from blood gas analysis, from an arterial blood sample, while StO2 is derived from the sensed tissue, by means of NIRS/DCS technology
|
20 minutes
