Adrenaline: It’s just a suggestion
Epinephrine and other ACLS drugs lead to more patients with ROSC but no increase in the number of patients with good neurologic outcomes after OHCA.
Something that’s very interesting is the actual 2015 ACLS recommendation for epinephrine. It reads, “it is reasonable to consider administering a 1 mg dose of IV/IO epinephrine every 3 to 5 minutes during adult cardiac arrest.” This actually leaves room to not give the medication if the physician thinks it should be withheld.
What ventricular fibrillation looks like…the ONLY treatment for this is Defibrillation. No amount of Chest Compressions will revert this to a Sinus Rhythm. Chest Compressions only maintain perfusion until you Defibrillate.
