Cardiac arrest & resuscitation
The association of tibial vs. humeral intraosseous vascular access with patient outcomes in adult out-of-hospital cardiac arrests
Authors' conclusion
We did not detect an association between the first-attempted intra-arrest IO site (tibia vs. humerus) and clinical outcomes.
