Thousands of peripheral venous accesses are inserted every day all over the world. Some of them, such as those inserted in emergency and / or in critical patients, are absolutely vital. In the particular context of prehospital care, the rate of failure of the first attempt to insert a peripheral venous access has been evaluated at 25%. Success rates of successive attempts were about 75%. Nevertheless, the final success rate is close to 100%.
Failure or delay in obtaining venous access can be life-threatening. Thus, alternatives to peripheral venous access have been proposed including intraosseous route recently made easier by the development of an automated puncture device (EZ-IO®), but still rarely used, especially on conscious patient.
Currently, the place of intraosseous venous access in critical patients is not determined.

| To demonstrate that the early recourse to the intraosseous route, from the first failure, makes it possible to obtain more quickly the correction of the failure of critical patient managed in prehospital setting. | • In patients with cardiac arrest: Time required for a return of spontaneous circulation (ROSC). Only the first ROSC will be considered. | • In patients with cardiac arrest: Return of spontaneous circulation (ROSC), an average of 1 hour |
| To demonstrate that the early recourse to the intraosseous route, from the first failure, makes it possible to obtain more quickly the correction of the failure of critical patient managed in prehospital setting. | • In patients with hemodynamic failure: delay to reach a systolic blood pressure correction, i.e. systolic blood pressure > 90 mm Hg. Systolic blood pressure will be assessed every 5 minutes after the placement of the intravenous line. Two consecutive measures are required to reach the end-point. In the cases where continuous invasive blood pressure monitoring will be available, systolic blood pressure > 90 mm Hg > 1 minute will be required. | • In patients with hemodynamic failure: Reach a systolic blood pressure correction, an average of 1 hour |
| To demonstrate that the early recourse to the intraosseous route, from the first failure, makes it possible to obtain more quickly the correction of the failure of critical patient managed in prehospital setting. | • In patients requiring endo-tracheal intubation: time required to achieve intubation. | • In patients requiring endo-tracheal intubation: Achieve intubation, an average of 1 hour |
