The aim of the study is to compare the values of cerebral tissue oxygenation measured simultaneously using laser light (FORE-SIGHT) and LED (INVOS) cerebral oximeters.

Cerebral Oxygenation

Study Type: Observational
Study Design: Observational Model: Case-Only
Time Perspective: Prospective
Official Title: A Comparison of Cerebral Tissue Oxygenation Values in Newborns Measured Simultaneously Using Laser and LED NIRS Oximeters

Further study details as provided by Poznan University of Medical Sciences:

Primary Outcome Measures:
  • Comparison of variability and repeatability of the recorded cerebral tissue oxygenation signals between two groups of patients (clinical stable preterm and term newborns) [ Time Frame: 6 hours ] [ Designated as safety issue: No ]

    There are two FDA-approved near infrared cerebral oximeters:

    1. FORE-SIGHT- which uses laser light
    2. INVOS 5100- which uses light emmiting diode.

    Measurements in adult patients have showed that FORE-SIGHT provides more stable signal. Purpose of our study is to compare these two devices in newborn patients.

Sampling Method:   Non-Probability Sample
Study Population
Clinically stable, spontaneously breathing newborns will be included in the study. Enrolled patients will be divided into two groups: 15 term (≥37 weeks GA) and 15 preterm (32-37 weeks GA) newborns. NIRS measurements will be performed on the 1st and 3rd day of life.

Inclusion Criteria:

  • Clinically stable
  • Spontaneously breathing newborns

Exclusion Criteria:

  • Congenital heart defects or anomalies of central nervous system
  • Prematurity below 32 GA
  • Respiratory distress
