Trauma Clinical Trial
Official title:
Detection of Exhaled Methane Levels for the Recognition and Monitoring of Hemorrhagic Shock - Study Protocol for a Prospective Observational Study
This prospective observational study aims to test the efficacy of the continuous measurement of exhaled methane levels in monitoring the hemodynamic state of severely injured, bleeding trauma patients.

Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Primary | Association between exhaled methane levels and vital signs | We intend to investigate the relation between exhaled methane levels and systolic blood pressure and heart rate. | First 72 in-hospital hours | |
Primary | Association between exhaled methane levels and blood gas and laboratory markers | We intend to investigate the relation between exhaled methane levels and blood gas and laboratory markers (base deficit, lactate, hemoglobin, hematocrit). | First 72 in-hospital hours | |
Primary | Association between exhaled methane levels and sublingual microcirculation | We intend to investigate the relation between exhaled methane concentrations and sublingual microcirculation. | First 72 in-hospital hours | |
Secondary | Association between exhaled methane levels and mortality | The relation between exhaled methane levels and mortality will be assessed. | First 72 in-hospital hours | |
Secondary | Association between exhaled methane levels and number of packed red blood cells required for transfusion/massive transfusion | The relation between exhaled methane levels and the number of packed red blood cells required for transfusion/massive transfusion will be assessed. | First 72 in-hospital hours |
