Peritoneal Dialysis Access
The GFR criteria in chronic kidney disease guidelines do not apply to children less than 2 years of age; these children can only be categorized as having normal, moderately reduced, or very severely reduced age-adjusted GFR. — Jan Scober, Managing Advanced Chronic Kidney Disease: Cincinnati Fetal Center · 20:42

- PD is the least technically difficult dialysis modality for small children; catheters should heal 2 weeks before use when possible, though immediate low-volume use is feasible.
- G-tube placement must be high on the lesser curvature to preserve stomach for future bladder augmentation; inadequate spacing from PD catheter causes infection.
- Infants on PD can be transplanted at 8 kg (vs. 10 kg off PD) due to abdominal wall laxity; all infant recipients receive adult donor kidneys extraperitoneally.
- Early PD after pediatric cardiac surgery reduces mortality, shortens ventilation and ICU stay; high-volume dialysis centers have 3× hospital survival and 2× one-year survival.
- PD catheter failure occurs in 30–50% of cases; hernias develop commonly but are managed conservatively unless they compromise dialysis mechanics.
When a baby has severe kidney problems before birth, doctors focus first on whether the lungs will develop normally, because that determines survival more than the kidney issues themselves . If the baby's amniotic fluid can be restored to normal levels through medical procedures, the chance of the lungs working well enough increases to about 80% [e622-c2, e916-c2]. Even babies who survive the delivery room may face ongoing breathing challenges, and their lung function may never be completely normal [e622-c6, e916-c5]. Many of these babies make large amounts of urine, even though their kidneys aren't working properly, which actually helps doctors manage their care . The medical team monitors growth carefully—if the baby stops gaining weight or growing in length, or if they can't control dangerous chemical imbalances in the blood with medicines alone, dialysis may be needed [e622-c20, e916-c14]. Peritoneal dialysis, where fluid is cycled through the belly to clean the blood, is the most practical option for small babies [e622-c21, e916-c15]. Most families find that one parent needs to stop working to care for the baby full-time [e622-c22, e916-c16]. When babies reach about 8-10 kilograms (roughly 18-22 pounds), usually in their second year, they may be large enough for a kidney transplant [e622-c10, e916-c19].
