BackgroundThe anterior tibia has been recommended as emergency vascular access site if the intravenous route cannot be used.ObjectiveThis study aims to evaluate the peripheral venous and anterior tibial intraosseous puncture as alternatives for dentists, using a human and a cadaver model.Method One group of dental students performed a venipuncture by using a standard catheter device (n = 21) on other students. Another group (n = 24) used the Vidacare EZ-IO intraosseous kit on a cadaver tibia with india ink as a tracer. Success rates as well as the time needed for a successful puncture were recorded.Results28.5% of venous and 83.3% of intraosseous punctures were successful. The relative risk of venous cannulation failure was 3.4 (95% CI 1.6-7.2; p = 0.0005). A successful venous access could be performed within 163 ± 23.2 seconds (mean ± SD), a tibial intraosseous access within 30 ± 27.8 seconds (p = 0.0003).ConclusionsWithin the limitation of this study, it can be demonstrated that the chances to perform a successful vascular access for inexperienced dentists may be higher when using the tibial intraosseous route for emergency intravascular medication.
