[Intraosseous device of perfusion. Apropos of 3 cases before hospitalization].

A renewal of interest in the intraosseous route has appeared lately in France. It concerns pediatric patients. After anatomophysiological and technical quotes, we report the indications, contraindications, method of supervision and complications of the placement of an intraosseous infusion. Our modest experience enables us to present three observations where intraosseous route has been used outside hospital in children suffering a cardiopulmonary arrest on arrival of the practitioner belonging to the mobile emergency unit. This rapid and easy to place technique seems to be attractive as an alternative to the intravenous route in situations of utmost emergency, this all the more so since there are few reported contraindications and complications.
