Polycythemia in the newborn.
Polycythemia (venous PCV greater than 65%) in neonates is not an infrequent occurrence. Over the last 2 years out of approximately 1500 admissions to the Neonatal Unit, polycythemia was detected in 46 babies (3.06%). Seventeen (36%) of these babies were preterm and 29 (63%) were term. Approximately one third were small for dates while 2 babies (4%) were large for dates. Four of them had been born to mothers with gestational diabetes and 7 were twin deliveries. Severe perinatal asphyxia (5 minute Apgar score less than or equal to 5) was present in 12 cases (26%). Symptoms suggestive of polycythemia included lethargy in 15%, refusal to feed in 13%, respiratory distress in 10%, vomiting in 8% and abdominal distension in 6%. Associated hypoglycemia was seen in 5 cases (10.8%) while twelve babies (26%) had significant jaundice (bilirubin greater than or equal to 12 mg/dl). Twenty eight babies (60.8%) were given a partial plasma exchange transfusion through the umbilical route. There was 6.5% mortality in these 46 babies with polycythemia. Blood letting through a peripheral vein along with a plasma infusion may be a safer alternative to partial plasma exchange transfusion through umbilical route in babies with polycythemia.
