Therapeutic leukapheresis of a 10‐year‐old girl with adult‐type chronic myelocytic leukemia is described. The efficiency of WBC removal was noted to improve significantly after addition of hydroxyethyl starch to the anticoagulant infusion. In fact, the percentage of white cells removed more than doubled (39% vs. 16%) when comparing procedures of similar duration, with and without the sedimenting agent. Of particular interest was the relief of the patient's respiratory distress concomitant with the decline in her leukocyte count, a finding that has not previously been documented in pediatric patients. The arterial oxygen pressure remained greater than 95 mmHg after the procedure with hydroxyethyl starch compared with 70 tnmHg after the procedures without it la addition, her respiratory rate decreased from 70 on admission to the low 20s after the final procedure. Leukapheresis with hydroxyethyl starch was shown to be a safe procedure, and the use of hydroxyethyl starch was shown to be of particular benefit for prevention of prolonged aphercsis procedures.
