Intraosseus (IO) Line Pearls – Dr. Paul Hannam
Choosing and Landmarking a Site for an Intraosseus Line
Proximal Tibia: Find the tibial tubercle, move 2cm inferiorly and 1 cm medially and insert the IO line 90 degrees to the bony plane
Proximal Humerus: Place your thumb on anterior humerus, feel for bicepital groove, the lateral “bump” is the greater tubricle – which is the site of a humeral IO.
Advantages of Humerus site: faster infusion rates and is easily landmarked.
Disadvantage of Humerus site: The arm must be immobilized in adduction, across the abdomen to prevent dislodging the needle. Requiring the arm to be immobilized may interfere with other resuscitative measures.
Avoid all bone sites where there is: a fracture, previous attempt, trauma or circulatory compromise proximal to the site
Choosing an IO Needle Length
EZ-IO kits have three needle lengths (15mm, 25mm and 45mm) and comes with weight-based recommendations for which needle to use for a given patient. Rather than using weight-based recommendations, our experts find it more useful to select the needle length according to the soft tissue thickness between the skin and bone of the patient at the given site. Estimate the soft tissue thickness and choose the needle that would accommodate that thickness. It is better to overestimate than underestimate the length of the needle required.
Update 2015: The squeeze test is an additional method to confirm IO placement, check it out on ALiEM.
Stabilizing and Securing the IO Needle
Ensuring that the needle does not move once it is placed is vital to avoiding leaking from the si...
