title: Stability of procaine hydrochloride in a cardioplegic solution containing bicarbonate.
abstract: The influence of preparation methodology and storage conditions on pH and procaine stability, in a cardioplegic solution, was studied. A solution prepared with carbon dioxide in the head space and stored at -10 degrees C showed acceptable stability.
