VICTOR RCT – IO or IV for OHCA?
Spoon Feed
Attempting initial vascular access in the field by intraosseous (IO) vs. intravenous (IV) route made no difference in survival to hospital discharge for out-of-hospital cardiac arrest (OHCA), despite greater IO success rates.Source
Intraosseous versus intravenous vascular access in upper extremity among adults with out-of-hospital cardiac arrest: cluster randomised clinical trial (VICTOR trial). BMJ. 2024 Jul 23:386:e079878. doi: 10.1136/bmj-2024-079878. PMID: 39043416. -

VF or VT – Earlier Defibrillation Is Better?
Spoon Feed
In a retrospective study of 142 patients with an initial shockable rhythm and 4 to 5 episodes of recurrent/refractory ventricular fibrillation (VF) or pulseless ventricular tachycardia (pVT), shorter duration of VF and pVT was associated with higher rates of ROSC.Source

Mechanism of Calcium for Hyperkalemia – Not What You Think
Spoon Feed
Giving calcium for hyperkalemia restores normal cardiac conduction velocity but does not restore resting membrane potential, as is commonly stated.Source
