The Peripheral(-Muscle) Oxygenation and Perfusion Score as a New Non-invasive Tool to Predict Elevations in C-reactive Protein Levels in Neonates
Sponsor: Medical University of Graz
Summary
This is a prospective, single-center Phase II observational study investigating the predictive value of the "Peripheral(-muscle) Oxygenation and Perfusion Score" (POP-Score), a novel non-invasive composite index, for early detection of infection/inflammation in neonates. The POP-Score combines peripheral muscle oxygenation measured via near-infrared spectroscopy (NIRS) with routinely monitored clinical parameters (heart rate, oxygen saturation, systolic blood pressure, and subcutaneous fat thickness). The study aims to determine the optimal cut-off value of the POP-Score measured within the first 6 hours after birth to predict elevated C-reactive protein (CRP ≥20 mg/L) within 48 hours. Additionally, multi-site NIRS measurements (cerebral, peripheral muscle, intestinal, and flank) will be evaluated to assess their association with inflammation. The study includes term and moderate-to-late preterm neonates (birth weight ≥2000g) with respiratory distress, admitted to the neonatal intensive care unit at the Medical University of Graz.

POP-Score Assessment
A non-invasive score calculated within the first 6 hours after birth using peripheral muscle oxygenation (pTOI, measured via near-infrared spectroscopy), heart rate, arterial oxygen saturation (SpO2), systolic blood pressure (SABP), and subcutaneous fat layer thickness. The score is evaluated for its ability to predict C-reactive protein (CRP) levels ≥ 20 mg/L within 48 hours.
Near-Infrared Spectroscopy (NIRS)
NIRS measurements are performed within 6 hours after birth using the NIRO 200NX device at four anatomical sites (forearm, forehead, infraumbilical region, and left flank). Measurements assess peripheral muscle, cerebral, intestinal, and flank oxygenation to identify possible differences in tissue perfusion associated with early inflammation or infection.
