    Abstract

    Postmortem changes in the pH of blood and selected tissues in rats were evaluated at intervals ranging from 2 min to 96 h. Cardiac blood pH was significantly and reproducibly decreased in all groups at all postmortem intervals, independent of the method of sacrifice used. A preliminary study using cardiac blood obtained at autopsy from a limited number (n = 11) of human subjects demonstrated a significant negative correlation (r = −0.908, P < 0.01) between postmortem interval (range 2 to 20 h) and cardiac blood pH.
