Abstract
This study was designed to determine whether the success rate in establishing intraosseous infusion (IOI) varied with four different types of needles--standard hypodermic, spinal, bone marrow, and Turkel intraosseous infusion needle. Twenty-four second-year residents from various specialties, without prior training or experience in the technique, participated in the study. Each participant attempted to establish an intraosseous infusion in a randomly assigned limb of an anesthetized piglet, using each needle in a randomly assigned order. The overall success rate was 67.7%. Success ratios varied between needles: hypodermic 54%, spinal 75%, bone marrow 75%, and Turkel 67%. Utilizing Cochran's Q-test, there was no statistical difference in success rates between needle types. However, in cases where the resident was successful with all four needles, the average time to successful infusion was significantly less for bone marrow needles.
