[Hemodynamometabolic changes in shock in infants. Report of 2 cases].
Two cases of infants with shock are presented. Cardiac output was determined in both with dilution dye using an auricular oxymeter, with three determinations: at 0, 30 and 60 minutes while receiving intranvenous fluids. At the same time, blood gases and blood lactatewere determined. The first case showed hypodynamic shock secondary to hypovolemia due to severe dehydration, associated to low central venous pressure, low arterial tension, increased peripheral resistance and increased arteriovenous difference of oxygen. The second case was a newborn with sepsis and disseminated intravascular coagulation with hyperdynamic shock with very high cardiac output, low peripheral resistance and low arteriovenous difference of oxygen. Both cases had an initial increase of lactate and a mild decrease at the end of the period of clinical observation.
