Abstract

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<0.001) at the end of surgery. Patients older than 30 months experienced a greater increase (P=0.0004). Those with more than 10 kg also had a greater increase (P=0.0006). In patients on extracorporeal circulation for more than 50 minutes, the increase in pulmonary compliance took longer...Continue Reading

Birth Defects

Birth defects encompass structural and functional alterations that occur during embryonic or fetal development and are present since birth. The cause may be genetic, environmental or unknown and can result in physical and/or mental impairment. Here is the latest research on birth defects.
