Brief Summary

The researchers are attempting to improve the cerebral monitoring of extremely low gestational age (ELGA) infants, such that in the future, real-time monitoring will be possible, to aid clinicians in management of these infants. The researchers wish to establish a new NIRS device, diffuse correlation spectroscopy (DCS), as a safe, noninvasive and informative bedside tool for assessing and monitoring brain health in ELGA infants during the first few days of life. It is hoped that this method will provide detailed information on changes in oxygen consumption and metabolism, and cerebral perfusion. This technique will have wide applicability, but for this research study, the researchers wish to focus on the effect of blood flow instabilities, intermittent hypotension and hypoxic episodes, pressure passive CBF periods, and hypoperfusion on the preterm brain during the first days of life, and the relationship with incidence of intraventricular hemorrhage (IVH). The researchers aim to recruit 100 premature infants to obtain data to:

  1. 1.Test the feasibility of NIRS-DCS to monitor cerebral activity, perfusion and oxygen consumption in extremely premature infants during the first week of life.
  2. 2.To assess if these baseline values are impacted by intermittent hypoxic episodes.
  3. 3.To assess if cerebral blood flow disturbances correlate with incidence of intraventricular hemorrhage.
  4. 4.Correlate the NIRS-DCS findings with clinical outcome at hospital discharge.

Study Arms (1)

ELGA group

EXPERIMENTAL

\*Less than 29 weeks Gestational Age (GA) preemies (100) DCS monitoring will be performed for up to 72 hours starting within 2 days after birth. In a subgroup of infants, we will also perform additional measurements with aEEG and FDNIRS. At a second stage we will add Transcranial Doppler Ultrasound (TCD)

Device: Diffuse Correlation Spectroscopy (DCS)Device: Amplitude Integrated Electroencephalography (aEEG)

Interventions

Amplitude Integrated Electroencephalography like EEG it is used clinically to monitor brain function in intensive care settings over longer periods of time. aEEG data will be correlated with CBF variation over time

ELGA group

Diffuse correlation spectroscopy uses light in the near infrared spectral region to quantify non-invasively cerebral blood flow. The DCS device will be use to monitor blood flow changes over time in all ELGA enrolled babies

Intervention Model
SINGLE GROUP
Model Details: Approximately 1.5% of infants born every year in the United States are born at an extremely low gestational age (ELGA \<29 weeks GA). As reported in the 2015 VON database, the risk for developing any grade of intraventricular hemorrhage (IVH) in ELGA infants is about 20% and in more than 90% of these cases it occurs during the first three postnatal days. The major risk factor for IVH is the gestational age of the infant with greater immaturity being associated with the highest risk. The degree of prematurity of the infant relates to the immaturity of the vascular bed within the germinal matrix as well as challenges in the regulation of the cerebrovascular circulation. Specifically, increases, decreases and significant fluctuations in cerebral blood flow (CBF) have been shown to play important pathogenic roles in IVH. We are investigating the possibility of using a novel optical method to quantify cerebral perfusion, continuously, at the bedside in the NICU preterm population.
