Successful management of CAPD in infants with cardiac failure
Insights
Continuous ambulatory peritoneal dialysis (CAPD) effectively manages infants with cardiac and renal failure, improving growth and development. Early CAPD initiation is crucial for optimal outcomes in these vulnerable pediatric patients.
Area of Science:
- Pediatric Nephrology
- Pediatric Cardiology
- Neonatal Intensive Care
Background:
- Infants with cardiac failure often experience concurrent renal failure.
- Dysplastic kidneys and ventricular septal defects (VSD) are common causes of combined cardiac and renal dysfunction in neonates.
- Continuous ambulatory peritoneal dialysis (CAPD) is a potential treatment for fluid and electrolyte imbalances in these infants.
Observation:
- Two infants with cardiac failure (VSD) and renal failure (dysplastic kidneys) were treated with CAPD.
- CAPD was initiated early in one infant (14 days old) and later in another (7 months old).
- Both infants showed improved water balance and physical growth with CAPD, alongside normal mental development.
Findings:
- The infant who received earlier CAPD demonstrated better weight gain and overall clinical progress.
- Delayed CAPD initiation in the second infant correlated with slower physical growth, despite CAPD management.
- Successful surgical correction of cardiac defects was achieved in the first infant while on CAPD.
Implications:
- CAPD is a recommended primary dialysis method for uremic infants with cardiac failure.
- Earlier initiation of CAPD may lead to improved clinical outcomes, including post-operative recovery after cardiac surgery.
- This study highlights the importance of timely intervention with CAPD for managing complex pediatric cases involving cardiac and renal comorbidities.
Abstract:
Continuous ambulatory peritoneal dialysis (CAPD) was selected and introduced as a primary dialysis method in two infants with cardiac failure. CAPD was started at 14 days after birth with body weight of 2125 gm and at 7 months of age with body weight of 2325 gm. In both cases, cardiac failure was due to large ventricular septal defect (VSD) and renal failure was due to dysplastic kidneys. In the first case (case 1), direct closure of atrial septal defect and patch closure of VSD were successfully completed at 9.5 months of age with body weight of 4844 gm. CAPD has been managed well for 1 year and 8 months and the child reached a body weight of 8440 gm. In the second case (case 2), CAPD was managed well for 11 months with body weight increasing to 4920 gm at the age of 1 year and 7 months. This marked deterioration of this boy's physical growth was mainly caused by the delay in introducing CAPD and partly due to his cardiac dysfunction which has not been corrected surgically. Both cases show almost normal mental development and are managed well at home. Although CAPD introduction yielded water balance and physical growth in these infants, earlier introduction of CAPD may result in better clinical outcomes including management following open heart surgery. Selection of CAPD as a primary dialysis maneuver is strongly recommended for uremic infants with cardiac failure.
