Abstract

Although apheresis techniques in children are well established, published experience with very low-weight children is limited. We reviewed 68 procedures performed in 19 children weighing less than 7 kg, including hematopoietic progenitor and T-cell collections and plasmapheresis. With significant modifications of standard techniques, all but one procedure was successfully and safely completed without serious citrate toxicity. Access was a major challenge. For plasmapheresis, the mean plasma volume removed was 1.2 × total plasma volume, but the mean total blood processed was 1.74 × total blood volume (TBV). For collections, the mean number of whole blood volumes processed was 4.1 × TBV. For T cell collections, the median CD3+ yield was 243.6 × 10⁶/kg. For HPC collections, the median CD34+ cell yield was 14.8 × 10⁶/kg. Mean durations for collections and plasmapheresis were 247.00 and 120.67 min, respectively. Of the CBC parameters, only platelet count was significantly lower after collections.
