Experimental Healthy control |
A total of 20 healthy age-matched newborns will have daily bedside FD-NIRS/DCS measurements of cerebral oxygen saturation (SO₂), cerebral blood flow (CBF), and cerebral metabolic rate of oxygen consumption (CMRO₂). |
|
|
Experimental Pharmacologic Treatment |
A group of 6 newborns with POE who are treated pharmacologically for severe neonatal opioid withdrawal syndrome will have daily bedside FD-NIRS/DCS measurements of cerebral oxygen saturation (SO₂), cerebral blood flow (CBF), and cerebral metabolic rate of oxygen consumption (CMRO₂). |

Detailed Description
The investigators propose to use a novel optical-based device that combines two advanced NIRS techniques, frequency-domain NIRS (FD-NIRS) and diffuse correlation spectroscopy (DCS), to quantify regional cerebral oxygenation (SO2), cerebral blood flow (CBF) and cerebral oxygen consumption (CMRO2) in neonates with similar ease of use as commercial NIRS devices, offering a more comprehensive metabolic profile of early brain function. Our technology has been validated in infant populations, demonstrating robust biomarkers of brain health and function in both healthy and at-risk infants. A pilot study at Riley Hospital for Children has already revealed differences in absolute cerebral oxygenation (SO2) as measured by quantitative FD-NIRS instrumentation in a small sample of neonates with POE and age-matched controls on the first 24 hours of life. The investigators hypothesize that infants who develop severe NOWS will exhibit early measurable alterations in cerebral oxygenation, blood flow, and/or metabolism in the early postnatal period. Thus, the investigators propose to acquire FD-NIRS/DCS measurements in infants with prenatal opioid exposure (POE) in their first days of life. Aim 1: Determine early trajectories of cerebral physiology in neonates with POE using a non-invasive FD-NIRS/DCS device. Aim 2: Investigate early associations between FD-NIRS/DCS measurements and short-term clinical outcomes in neonates with POE. Aim 3: Monitor changes in cerebral physiology during pharmacologic treatment in infants with severe NOWS.
