Normal values for cardiopulmonary exercise testing in children.

Background: A reference set of data of normal values of newly developed cardiopulmonary parameters of exercise testing in an 8-18-year-old population is lacking.

Patients And Methods: Cardiopulmonary exercise testing was performed in 175 healthy school children (8-18 years old). Continuous electrocardiography was performed, and minute ventilation, oxygen uptake (VO2), and carbon dioxide (CO2) production were measured continuously with a respiratory gas analysis system.

Diastolic dysfunction in paediatric patients on peritoneal dialysis and after renal transplantation.

Background: Cardiovascular disease is the leading cause of death in children with end-stage renal disease. We investigated the presence of cardiac systolic and diastolic dysfunction in patients on peritoneal dialysis or after renal transplantation. Methods and results.

Metabolic alkalosis after pediatric cardiac surgery.

Objective: To determine occurrence, causes and associated mortality of postoperative metabolic alkalosis in pediatric cardiac surgery.

Methods: We retrospectively analyzed clinical and biochemical variables of 186 consecutive cardiac operations other than ductal ligations on children less than 2 years old during the years 1999 and 2000. Metabolic alkalosis was defined as a pH>7.
