Description
Summary:Analysis of pulmonary status of pediatric patients in the postoperative phase of cardiac surgery. To assess pulmonary compliance and airway resistance in patients with congenital heart disease and pulmonary hyperflow submitted to surgical treatment with the use of extracorporeal circulation. Thirty-five patients were evaluated during surgery with measurements of static compliance and airway resistance at four different timepoints. Pulmonary measurements were performed non-invasively using end-inspiratory airway occlusion and specific mathematical formulas. The variables examined and related to pulmonary changes were: preoperative - age, weight, and relationship between systemic and pulmonary blood flow; intraoperative - perfusion times, anoxia times and minimum temperature; postoperative - time on mechanical ventilation and length of stay in the intensive care unit. Pulmonary compliance in all patients had an immediate and significant increase (P
