title: Complications of therapeutic plasma exchange: a recent assessment.
abstract: The use of therapeutic plasma exchange, particularly for management of patients with neurological disorders, has steadily increased in our hospital since 1991, thus highlighting the need for continuing quality assurance of these services. We have reviewed the hemapheresis records of all 381 therapeutic plasma exchange procedures performed on a total of 63 patients from January 1991 through December 1992. Patients were referred for therapeutic plasma exchange for the following indications: acute Guillain-Barre syndrome, 31 patients (49.2%); chronic inflammatory demyelinating polyneuropathy, 15 patients (23.8%); myasthenia gravis, five patients (7.94%); paraproteinemic neuropathy, five patients (7.94%); thrombotic microangiopathies, six patients (9.52%) and Goodpasture syndrome, one patient (1.6%). Overall, 89% of patients were treated for neurological disorders. Complications of plasma exchange were noted during 17% (n = 65) of procedures involving 49% (n = 31) of patients treated. Approximately 91% of complications were classified as mild (55.4%) or moderately severe (35.4%) and did not prevent successful completion of the procedure. These were largely related to use of citrate-containing anticoagulants and additionally may have reflected the autonomic instability of many of the neuropathy patients. All four (6.15%) severe complications and one of two fatalities were related to the use of central venous access catheters. We conclude that therapeutic plasma exchange can be performed safely with acceptable toxicity caused by mild and moderately severe complications. Major complications may be minimized by careful management of central venous catheters when required for access.
