How To Do Intraosseous Cannulation, Manually and With a Power Drill
Warnings and Common Errors for Intraosseous Cannulation
When the tip of the intraosseous needle first contacts the bone surface, at least 5 mm of the needle should be visible outside the skin so that the needle tip will be able to reach the marrow cavity. If the needle does not extend that far, a longer needle may be needed. Avoid drilling until the needle hub is flushed with, or indenting into, skin surface. This can cause damage and skin necrosis.
