Intraosseous administration of digoxin: same-dose comparison with intravenous administration in the dog model.

Intraosseous access has become the method of choice for venous access in critically ill and injured children when more traditional methods are not immediately available. However, there is a paucity of information concerning drug levels achieved via the intraosseous route. We report initial data on the comparison of serum digoxin levels after administration of the drug to dogs through both the intraosseous and intravenous routes. These data indicate that intraosseous infusion of digoxin results in similar serum levels to those attained after IV administration, and may therefore afford a reliable means of initial digitalization.
