Why the study?
Does infusion of cold blood following potassium arrest improve acute recovery and reduce ventricular fibrillation in a canine model of elective cardiac arrest?
Population
Dogs undergoing elective cardiac arrest (normothermic and hypothermic to ~20℃)
Comparison
Infusion of cold blood into coronary arteries… vs Potassium arrest alone, acetylcholine arrest…

Animal data on cold blood post-arrest remain preliminary; leaves open translation to human cardioplegia strategies.
Does infusion of cold blood following potassium arrest improve acute recovery and reduce ventricular fibrillation in a canine model of elective cardiac arrest?
In a canine model, myocardial hypothermia achieved by infusing cold blood after potassium arrest minimized ventricular fibrillation and optimized acute physiological recovery.
Berne et al. (1958) studied this question.
