Plasma exchange treatment can be used for any clinical picture whose disease-causing substance is in the blood plasma.
The patient's blood cells are separated in the connected cell separator and immediately reintroduced to the patient (animation step 1).
At the same time, the blood fluid ("bad" plasma) is exchanged for a replacement fluid (albumin solution) (animation step 2).
Although plasma exchange is now considered technically outdated, it is still justified for the treatment of certain diseases or for special indications
Examples are: Multiple sclerosis (acute steroid-resistant relapse), myasthenia gravis, Lambert-Eaton syndrome, treated chronic neuroborreliosis (antibiotic-resistant late phase, experimental stage).
Instead of unspecific plasma exchange, selective procedures are predominantly used today, whereby the patient's own plasma or, more rarely, the purified whole blood is returned to the patient
