Buffer agents do not reverse intramyocardial acidosis during cardiac resuscitation.


We investigated the effects of carbon dioxide-producing and carbon dioxide-consuming buffers on intramyocardial pH and on cardiac resuscitability. In 29 pigs, intramyocardial pH was continuously measured with a glass electrode advanced into the midmyocardium of the posterior left ventricle through a diaphragmatic window. Ventricular fibrillation (VF) was… (More)
