Original article: cardiovascularPredictors of mortality at initiation of peritoneal dialysis in children after cardiac surgery
Section snippets
Study population
The records of all children with peritoneal dialysis after cardiac surgery by means of cardiopulmonary bypass who were treated in our pediatric intensive care unit between June 1993 and December 2001 were reviewed retrospectively. Exclusion criteria were a postoperative course of extracorporeal membrane oxygenation, peritoneal dialysis for less than 1 day, or incomplete data. Hemodynamic data were continuously monitored by means of a Hewlett-Packard monitoring system (Model 68 S;
Results
Between June 1993 and December 2001, 1,141 children underwent a cardiac operation on cardiopulmonary bypass at the University hospital of Vienna. A total of 62 of the 1,141 children (5.4%) were treated with peritoneal dialysis and were eligible for this retrospective study. Table 1shows the different congenital heart defects and the operations performed. Table 2shows the number of patients of each indication for peritoneal dialysis. The cause of death was low cardiac output in 21 cases (acute
Comment
In this retrospective study we reviewed the medical records of pediatric intensive care unit patients treated for renal dysfunction after cardiac surgery. When we compared survivors and nonsurvivors we found that pH, base excess, lactate, PIP, and TV/kg could significantly identify children at high risk of mortality at time of peritoneal dialysis initiation after cardiac surgery whereas mean arterial pressure, central venous blood pressure, central venous oxygen saturation, and urinary output
