Table 4.

A table representing the capabilities and limitations of kidney support therapies available to neonates. NEC, necrotizing enterocolitis

Kidney support modality Benefits Limitations Complications Mode of clearance
Peritoneal dialysis - Ease of use
- No vascular access
- Can be used if hemodynamically unstable
- Limited precision of the exact amount of fluid and waste product removal
- Unable to use if intraabdominal complications (e.g., NEC, intrabdominal surgery, congenital diaphragmatic hernia)
- Must wait until catheter heals to use for prolonged use
- Catheter migration
- Catheter malfunction
- Catheter infection
- Peritonitis
- Hyperglycemia
- Hyponatremia
- Hypoalbuminemia
Diffusion
Extracorporeal support (CARPEDIEM, Nidus, Aquadex) - Highly efficient waste product clearance
- Precise fluid removal
- Low extracorporeal volume filter/tubing enables smaller catheters, and decreases hemodynamic instability compared to traditional larger KST circuits
- May start therapy immediately after catheter placement
- Requires vascular access
- May be restricted based on size of vessel
- Requires specialized machines
- Requires higher expertise/training
- Requires anti-coagulation of the circuit
- Catheter migration
- Catheter thrombosis
- Catheter infections
- Hemodynamic instability (although this is much lower than traditional KST machines)
