RESUMO
Ten neonates, asphyxiated at birth, were studied by Apgar score, ECG ischaemic score grading (ECGisg), Cardiothoracic (CT) ratio, biochemical parameters like CPK, CPK-MB fraction during life; and they were subjected to postmortem study with particular attention to the changes in the heart. The study revealed that 7 out of 10 asphyxiated neonates showed variable evidences of myocardial damage; but the extent of damage though well correlated with biochemical parameters, did not correspond well with the extent of asphyxia and the survival period. In rest 3 cases, myocardial damage was not overt though there was evidence of asphyxia and evidence of myocardial damage in the form of elevated CPK-MB level. These patients probably had died of "Biochemical Lesion" as described by Rudolf Peter.
