A site for intraosseous access Intraosseous infusion is a method to obtain vascular access during critical states when a peripheral vein is not accessible to administer drugs and fluids; is used in neonates and children, although lately the tools have been adapted to be used in adults.

In 1936, Tocantins and O'Neill found that when injecting saline into a rabbit's long bone, only 2 mL were recovered on the distal side. They concluded that the solution had been absorbed into the circulatory system. Subsequent tests concluded that the absorption was that of an injection that was accompanied by a dye, in less than 10 seconds, this dye had reached the heart.
