Brief Summary:

Premature infants are at high risk for variations in blood pressure and oxygenation during the first few days of life. The immaturity of the premature brain may further predispose these infants to death or the development of neurologic problems. The relationship between unstable blood pressure and oxygen levels and brain injury has not been well elucidated.

This study investigates the utility of near-infrared spectroscopy (NIRS), a non-invasive oxygen-measuring device, to identify preterm infants at highest risk for brain injury or death.

Group/Cohort Intervention/treatment
Preterm infants monitored with NIRS
All infants enrolled in the study will be monitored with cerebral near-infrared spectroscopy (NIRS monitoring) to measure cerebral oxygenation levels in the first 96 hours of life. Mean arterial blood pressure will simultaneously be monitored.
Device: NIRS monitoring
All enrolled infants will undergo NIRS monitoring of cerebral oxygenation in addition to monitoring of continuous arterial blood pressure.

Primary Outcome Measures :
  1. Mortality before hospital discharge [ Time Frame: Outcome measure will be assessed at the time of subject's initial discharge from the hospital (on average by 40 weeks postmenstrual age), but at a maximum of 1 year of life. ]
    Participants will be followed for the outcome of death prior to hospital discharge.

  2. Severe central nervous system (CNS) morbidity [ Time Frame: Outcome measure will be assessed on day 10 of life. Participants will be followed for neuroradiographic evidence of CNS morbidity in the first ten days of life ]
    Routine cranial ultrasound obtained within the first ten days of life will be utilized to detect grade 3 or 4 intraventricular hemorrhage, periventricular leukomalacia, significant ventriculomegaly, or white matter abnormalities.

Layout table for eligibility information
Ages Eligible for Study:   up to 24 Hours   (Child)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Sampling Method:   Probability Sample
Study Population
All inborn preterm infants with birth weight <=1250 grams and with an indwelling arterial catheter already in place are eligible for study enrollment if they are <24 hours old at the time of enrollment. These preterm infants are at risk for impaired cerebral autoregulation and may undergo non-invasive monitoring of cerebral oxygenation using near-infrared spectroscopy (NIRS).

Inclusion Criteria:

  • inborn
  • birth weight <= 1250 grams
  • indwelling arterial catheter in place
  • age <24 hours old

Exclusion Criteria:

  • lethal chromosomal abnormality
  • major congenital anomaly
  • skin integrity insufficient to allow placement of NIRS sensors
  • decision to not provide full intensive care
