Prone Positioning Short-term Effects on Tissue Oxygen Saturation in Critical COVID-19 Patients (PRONECOVID19)

July 27, 2022 updated by: Jaume Mesquida, Corporacion Parc Tauli

Short-term Effects of Prone Positioning on Tissue Oxygen Saturation, Measured by Near-infrared Spectroscopy, in COVID-19 Patients With Acute Respiratory Distress Syndrome

The purpose of this study is to monitor short-term changes in tissue oxygen saturation and local blood flow as results of changing from supine to prone position in ARDS COVID-19 patients

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.

Design Details

What is the study measuring?

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
