Comment on "Factors affecting the clinical outcomes in pediatric post-cardiotomy patients requiring perioperative peritoneal dialysis".

In a retrospective article entitled “Factors affecting the clinical outcomes in pediatric post-cardiotomy patients requiring perioperative peritoneal dialysis,” the authors investigated factors associated with mortality in pediatric patients undergoing perioperative peritoneal dialysis after cardiotomy 1 . In this study, the authors found that younger preoperative age, longer car-diopulmonary bypass time, prolonged intubation, prolonged inotropic support, and need for extracorporeal membrane oxygenation were associated with a higher risk of mortality. In our opinion, although the findings of this study are of great value, there are some issues that need to be addressed.
