Lula Lubchenco, MD, was a pioneering pediatrician in Colorado, where she developed protocols and tools used in delivery rooms around the world to categorize newborns and determine the risk of health complications. Dr. Lubchenco’s research insights and the use of her Lulagram chart helped shape the field of neonatology. She began publishing her research on the relationship between birth weight and gestational age in newborns. In this research, she developed a chart that allowed clinicians to plot a baby’s birth weight against its gestational age – this chart became known as the “Lulagram.” Additionally, one of her essential research studies was the follow-up of infants born prematurely due to mothers with Rh incompatibility. Her work helped obstetricians develop protocols that led to the prevention of Rh sensitization in mothers.
