Here's my first lecture from SMACCgold: The New Intra-Arrest. It generated a bit of controversy amongst my critical care friends, so we'll be discussing various parts in more detail in the coming weeks.

Why Epi and not Phenylephrine
From MH Weil's Article Above:
Adrenergic agents with predominant a2 effect have been shown to be more effective as vasoconstrictor drugs, presumably because extrajunctional a2-receptors are more accessible to circulating catecholamines than postjunctional a1-receptors. This may explain why adrenergic amines that have predominant a1 actions such as methoxamine (Vasoxyl) and phenylephrine (Neo-Synephrine) are less effective than epinephrine after prolonged cardiac arrest.
Note: To do hemodynamic dosing of vasopressors properly, it is imperative you read this post (choosing the correct DBP); you should also probably listen to that podcast.
LUCAS seems equivalent to excellent manual compressions (from ResusMe)
Cardiac Arrest: To the cath lab with ongoing chest compressions?
Steve Smith has a great post on the topic with a ton of evidence
Consider Dual-Shock for Non-Converting VF/VT
Charles Bruen has a great post with the evidence
But it may fry your defib and you won't even know it2
