Intraosseous access is indicated in emergency situations, such as when a person experiences some type of major trauma like shock, cardiac arrest, severe dehydration, [8] or severe gastrointestinal hemorrhage. [9] IO access can provide the quickest way to rapidly infuse needed medications and fluids in an emergency situation. [8]
In emergency situations when peripheral access cannot be easily achieved, such as in arrest scenarios, intraosseous methods can be used to gain rapid access to the venous system. These methods usually involve inserting an access device into the tibia or femur bones in the legs, humerus in the upper arm, or sometimes the sternum in the chest. [2 ...
Intraosseous infusion (into the bone marrow) is, in effect, an indirect intravenous access because the bone marrow drains directly into the venous system. This route is occasionally used for drugs and fluids in emergency medicine and pediatrics when intravenous access is difficult.
Intraosseous access is commonly obtained by inserting a needle into the bone marrow of the humerus or tibia, and is generally only considered once multiple attempts at intravenous access have failed, as it is a more invasive method of administration than an IV. [17]
