[Study upon oxygen conveyance in severe anaemia. About a very serious case of hemolytic anaemia which led to a myocardial infarct (author's transl].

To understand the orientation the metabolism of a sick person whose arterial content in oxygen had collapsed (CaO2 reaching 1,9 vol/100 ml) the cardiac output and the rate myocardic extraction of the lactates have been measured. The cardiac index was very high 7,4 l/m/m2 and in spite of a low D (a-v) (2,5 vol/ml) the consumption of oxygen was normal. Three days after a first measure the steep (or brutal) fall of the cardiac and the reversal of the rate of myocardic extraction of lactate led up to diagnose an acute coronary insufficiency. The electrocardiogramm only cortoborated the myocardic necrosis in a second time. This result invites (or calls for) a constant electrographic watching of sick persons who suffer from severe anaemia, even with sane coronary vessels, to avoid diagnosing coronary insufficiency through so circuitous means.
