Use of Bedside Ultrasound to Assess Neonatal Body Composition in the Neonatal Intensive Care Unit


This is an observational study to evaluate the ability of ultrasound measurements to measure and routinely monitor the body composition of healthy preterm infants in the neonatal intensive care unit (NICU) in response to nutritional intake and to generate a prediction equation for percent body fat from three ultrasound measurements of adipose tissue (biceps, abdomen, quadriceps). We will assess ultrasound as a method to measure neonatal body composition by comparing it to the validated method of air displacement plethysmography.
