Centrifugal Therapeutic Plasma Exchange in Pediatric Patients

To assess the safety of centrifugal therapeutic plasma exchange (TPE) in pediatric patients.

The authors did a retrospective analysis of all TPE procedures performed in pediatric patients over a period of 19 y (2001-2019). Procedures were done on different apheretic devices, daily or on alternate days depending on the clinical condition of the patient. Adverse events during the procedure were noted and analyzed.

A total of 672 TPE (with mean of 6.77 ± 4.85) procedures were performed for 99 pediatric patients with different indications like hematological (n = 68), renal (n = 12), neurology (n = 18) and hepatology (n = 1). The mean age was 7.00 ± 3.11 y and weight was 20.72 ± 9.17 kg. Adverse events (AEs) were observed during 34 (5%) procedures, most common were allergic reactions to replacement fluid (2.24%) followed by hypotension (1.04%), symptomatic hypocalcemia (1.04%), line occlusion (0.59%), and febrile non hemolytic transfusion reaction (0.41%). A significant correlation of AEs was observed with weight (p = 0.045), total blood volume of the patient (p = 0.04), increasing number of procedures (p = 0.000) and replacement fluid [Fresh frozen plasma (FFP)] (p = 0.04). All AEs were managed as per departmental standard operating procedures (SOPs) completing procedures successfully except one which was abandoned. No mortality was observed during the procedures.

TPE is a safe therapeutic modality in pediatric patients when performed under expert technical supervision with proper SOPs in place.
