It can be difficult to identify those infants who fall into the categories AABB lists as those that require irradiated products. One of the immune deficiencies encountered in infants is DeGeorge syndrome (an immunodeficiency that often occurs with cardiac anomalies). That diagnosis is not identified immediately upon admission to a NICU or CVICU. My institution has a 98 bed NICU and a 28 bed pediatric CVICU. For patient safety, we irradiate all products for infants in NICU or CVICU regardless of their birthweight. Yes, we do have our own irradiator. We also limit donor exposure by designating a specific unit for a baby and use until its expiration for small volume transfusions. If a large volume transfusion is needed (for OR) a fresh, irradiated unit is selected. And we do give fresh, < 5 day old blood to all cardiac surgery patients < 2 years of age.
