Whose at risk for RDS? Obviously preemies. In our life now, in 2004, if babies are born at less than 34 weeks gestation, we consider them to be at high risk for respiratory distress syndrome. But another funny category is infants of diabetic mothers, because they can have RDS at a higher gestational age than 34 weeks. We have often seen 36, 37 week infants of diabetic mothers who weigh 4 kg, who are lying in our ICN with grunting, flaring, and retracting, and it is a very funny picture to see a large baby with a breathing pattern of a preemie. I am not going to go into why they have that today, but perhaps at another time, we can have a talk about that. Also, babies who have some degree of perinatal asphyxia that has existed prior to delivery for some time, can have signs and symptoms of RDS. So the big thing to remember is that all of these risk categories relate to suboptimal surfactant production. So, if the fetus doesn't elaborate surfactant, the baby is going to have RDS.
