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.
• Healthy, premature infants 25-34+6 weeks gestational age at birth
• Admitted to the University of Minnesota Masonic Children's Hospital NICU
• Stable on room air or can be removed from respiratory support for 5 minutes
• Written or verbal (telephone) informed consent can be secured from a parent within 1 week of admission to the NICU
