Detailní popis
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.

Severity of neonatal opioid withdrawal
Časové okno: From birth to study completion, an average of 14 days.
|
The numerical modified Finnegan score (FNAST) or the Eat, Sleep, Console (ESC) score, depending on which tool is used for scoring at the site, will be recorded closest in proximity to measurements of cerebral physiology.
The FNAST is a long-standing scoring tool that gives a numerical score as a measure of severity of withdrawal, with higher scores being more severe, up to a maximum of 24.
The ESC score is a newer scoring tool that is not numerical but rather normal or abnormal in 3 categories of symptoms.
Having an abnormal score for any of the 3 categories may qualify for intervention.
