[Demystifying the intraosseous infusion technique]

Intraosseous infusion provides a safe and effective access to the vascular system that allows for administration of urgent therapies in both adults and children. It has few contraindications and complications are rare. The needle is most commonly inserted in the proximal tibia or anterior humerus. Different devices are available but those with a traditional drill are the most widespread. The intraosseous infusion procedure is easy and the learning curve is short, making it the best alternative when traditional intravenous access is not possible or delayed.
