Plasma exchange therapy in pediatric patients. Plasma filtration with a unipuncture technique

Therapeutic apheresis in children is limited by technical considerations, such as circuit blood volume, venous access and hemodynamic instability. Here we report our experience with 310 plasma-filtration sessions in 44 children (aged 9 months-17 years). We used a miniaturized circuit with a unipuncture technique and a "balancing system" which assured a permanent fluid equilibrium. This procedure is well adapted to children and always made pediatric plasma exchange therapy easier and safer. The more common indications remain Guillain-Barré syndrome and acute severe glomerular diseases.
