Powikłania u chorych leczonych metodą plazmaferezy na oddziale intensywnej terapii Complications in patients treated with plasmapheresis in the intensive care unit

Background. Plasmapheresis is one of the methods of extracorporeal blood purification involving the removal of inflammatory mediators and antibodies. The procedure is used in a variety of ailments, including autoimmune diseases. The aim of the present study was to analyse the incidence of plasmapheresis-related complications in patients treated in the intensive care unit (ICU). Methods. The analysis involved 370 plasmapheresis procedures in 54 patients. The data were collected from patients` medical records, including procedure protocols. Results. The most common diseases treated with plasmapheresis included: myasthenia gravis (33.3%), Guillain-Barre syndrome (14%), Lyell’s syndrome (9.3%), systemic lupus erythematosus (7.4%), and thrombotic thromcytopenic purpura (7.4%). The adverse side effects observed most frequently during plasma filtration were decreases in arterial blood pressure (8.4% of all procedures), arrhythmias (3.5%), sensations of cold with temporarily elevated temperature and paresthesias (1.1%, each). In most cases, the symptoms were mild and transient. Severe and life-threatening episodes, i.e. shock, drops in arterial blood pressure requiring catecholamines administration, persistent arrhythmias and haemolysis, developed in 2.16% of procedures. Conclusions. Plasmapheresis can be considered a relatively safe method of treatment of ICU patients. Continuous observation and proper monitoring of patients provided by highly trained medical personnel are essential for its safety.
