Peritoneal dialysis in infants and children with acute renal failure after congenital heart surgery

Abstract

Objective To investigate the use of peritoneal dialysis (PD) therapy after cardiopulmonary bypass surgery in infants and children with acute renal failure,and to determine the risk factors associated with mortality undergoing peritoneal dialysis.Methods The clinical records of 21 children,aged 13d～3 years,who had undergone open heart surgery during 2009.3-2011.12 were reviewed.The clinical and laboratory variables were compared between the survivor and non-survivor groups of ARF patients who needed PD.Results Of the 21 patients,4died,with the overall mortality rate of 19.05％.The causes included muhi-organ failure (2 cases),arrhythmia (1cases),and airway hemorrhage (1 case).17 patients were cured,with normal urinary volume,serum BUN and serum creatinine levelat discharge.Renal function maintained well from 2 months to 6 yearsduring following up.When compared with survivors,non-survivors were more likely to have had circulatory arrest and multiorgan failure.Conclusions PD is a safe and effective method for managing patients with acute renal failure after open heart surgery.Risk factors for patient survival in young children undergoing open heart surgery are circulatory arrest and multiorgan failure.
