STUDY OBJECTIVES To compare infusion rates from various intraosseous sites (tibial, medial malleolar, distal femoral, and humeral) and at a peripheral IV site under gravity and pressure flow in normovolemic and hypovolemic states. DESIGN AND SETTING A piglet model was used to assess rates of infusion under varying conditions in a university hospital(More)
OBJECTIVES To examine: a) the rate and extent of delivery of radioactive tracers to the central circulation from the tibial, medial malleolar, distal femoral, and humeral intraosseous sites, as well as from a peripheral intravenous site; and b) the end-tidal CO2 response to injected sodium bicarbonate at these sites.
