I​​ntraosseous (IO) devices are traditionally used in the initial stages of resuscitation when peripheral intravenous (IV) access is not readily obtainable. This can happen for a variety of reasons such as edema, burns, obesity, or IV drug abuse among others. Although ultrasound can be used to obtain peripheral or central venous access, the most rapid route is the IO. The device has been used both in adults and children with great success. It can safely facilitate the delivery of fluids, medications, and blood. There are very few contraindications and it is rare to have a complication.
