Adverse effects secondary to the treatment with plasma exchange.

Side effects and their relationship with the material used were analyzed in 748 plasma exchanges (PE) performed in 75 patients. The total incidence of acute and mild adverse effects (chills and/or fever, paraesthesias, allergic reactions, acute anaemia, vasovagal reactions, abdominal pain and hypotension) was 18.04%. Two patients developed an episode of left cardiac insufficiency. One patient in whom all PE were performed with fresh frozen plasma (FFP) developed metabolic alkalosis. Three patients developed sepsis during treatment with repeated PE and immunosuppressive drugs; in these three patients a permanent vascular inlet was used (shunt or catheter). All patients in whom only FFP was used as replacement solution developed non-A, non-B hepatitis. Neither haemorrhagic nor thrombotic episodes were observed in these patients. It is of the greatest importance to choose the most suitable material for each patient and to develop a careful technique in order to avoid these complications during treatment with PE.
