Polarized Arrest With Warm or Cold Adenosine/Lidocaine Blood Cardioplegia is Equivalent to Hypothermic Potassium Blood Cardioplegia
This study tested the hypothesis that elective arrest in a polarized state with adenosine (400 mumol/L via adenosine triphosphate-sensitive potassium channel opening) and the Na + channel blocker lidocaine (750 mumol/L) as the arresting agents in blood cardioplegia provides cardioprotection comparable to standard hypothermic K + -blood cardioplegia.
