Dialysis for Children: How Hemodialysis and Peritoneal Dialysis Differ

When a child with kidney failure needs dialysis, the choice is not simply about which treatment is better. It is about finding an approach that suits the child’s medical condition, daily life and growth, as well as the family’s ability to provide care.

Hemodialysis filters the blood through a machine outside the body to remove waste and excess fluid. It requires access to the bloodstream and is usually carried out at a specialist treatment center, making travel and scheduled visits important considerations for families.

Peritoneal dialysis uses the lining of the abdomen as a filter. Dialysis fluid enters and leaves the abdomen through a catheter, carrying away waste and excess fluid. It can often be performed at home after caregivers receive training, but requires careful hygiene and consistent management.

Both methods carry risks and practical demands. Hemodialysis requires care of the blood-access site, while peritoneal dialysis requires close attention to the catheter and the risk of abdominal infection. The child’s medical needs and the support available at home help determine which approach is suitable.

The decision should be made with the child’s kidney care team, taking nutrition, growth, schooling and family routines into account. Neither method is the best choice for every child, and the treatment plan may need to change as the child’s needs evolve.
