title: [Hemodynamic course in relation to mechanical ventilation in the postoperative period of extracorporeal surgery in children].
abstract: Hemodynamic evolution and its relationship with the factors that have an effect upon gaseous exchange, during the early phase after extracorporeal circulation in sixty nine children, are reviewed. They are divided into three groups: group I (APH), arterial pulmonary hypertension; group II (OF), overflow, and group III (C), control. Results in the three phases of mechanical ventilation (IPPV, IMV and CPAP), are compared. We found that only in group I (APH), the pulmonary mechanics was altered. The programmed hyperventilation (IPPV) in group III (C), underlie the results of correlation between ventilatory and hemodynamic parameters with the oxygenation. There are high pulmonary vascular resistance in group I (APH); this explains the positive correlation between diastolic pulmonary arterial pressure and cardiac output. There are a good right ventricle function in I (APH) and III (C) groups. The hemodynamic patterns in IPPV are not depending on the pulmonary state.
