Preemies: Novel feeding device may decrease risk of failure to thrive

Professor and nurse practitioner Barbara Medoff-Cooper, PhD, CRNP, of Penn Nursing invented a device that analyzes an infant's ability to organize feeding by sucking, swallowing, and breathing effectively. This device, developed in collaboration with Penn bioengineers, allows healthcare professionals to assess infants at risk for dysfunctional feeding and poor weight gain as often seen in both premature infants and infants with complex congenital heart disease. The data also can be correlated with growth or developmental problems that may occur during the first year of life.

"Feeding actually speaks loudly to us about the brain," says Dr. Medoff-Cooper. "If a child is feeding well, it gives us one fewer major issue to worry about. Conversely, even a full-term infant who is not feeding well is at high risk for developmental problems."

Dr. Medoff-Cooper conducted the first comprehensive evaluation of feeding difficulties in infants with complex congenital heart defects. Her work has demonstrated that feeding behaviors can predict developmental outcomes in high-risk infants because of the complicated interplay of movements and physiologic responses needed in the feeding process. The premise of her work is that feeding effectiveness corresponds to how well infants will achieve other developmental milestones.
