A method of obtaining immediate access to the circulation by inserting a needle through the skin, subcutaneous tissues, and periosteum into the marrow cavity of a long bone, usually the proximal tibia. Once access is gained, substances may be injected into the bone marrow, where they are absorbed almost immediately into the general circulation. This avenue of access does not collapse in the presence of shock. Synonym: intraosseous injection
Drugs infused intraosseously should be followed by a bolus of 5 mL or more of normal saline.
