Avoidance of red blood cell transfusion in an extremely preterm infant given recombinant human erythropoietin therapy.
To avoid red blood cell (RBC) transfusions, recombinant human erythropoietin (rHuEPO) was given to an infant born at a gestation of 26 weeks and a birthweight of 830 g to parents who were Jehovah's Witnesses. The infant had hyaline membrane disease and required 52 days of assisted ventilation and 19 days of oxygen therapy. He received theophylline therapy for 61 days for recurrent apnoea and bradycardia. He developed bilateral intraventricular haemorrhage (IVH) and left-sided periventricular leucomalacia (PVL). Intravenous rHuEPO was started on day 1 at 200 U/kg per day for 1 month followed by subcutaneous rHuEPO 400 U/kg three times a week for 6 more weeks, supplemented with Vitamin E, folic acid and iron. Blood sampling was kept to a minimum and non-invasive blood-gas monitoring was used consistently. Consequently, the estimated cumulative volume of blood loss from sampling was only 21 mL during his hospital stay. His haemoglobin (Hb) was 150 g/L at birth and this fell to below 100 g/L from day 25 onwards. His lowest leucocyte count was 3.6 x 10(9)/L. He was discharged on day 83 with a Hb of 95 g/L, Hct of 29%, reticulocyte count of 2.8% and weight of 2400 g. At a postnatal age of 3 months, he had a Hb of 113 g/L. At 6 months, investigations showed: Hb 121 g/L, haematocrit 33%, reticulocyte 1% and a weight of 4.4 kg. He was readmitted to hospital once for an episode of vomiting and follow up to date showed developmental delay.(ABSTRACT TRUNCATED AT 250 WORDS)
