NIRS Monitoring in Premature Infants

Summary

Third Opinion Trial Synopsis:
This study is looking at how a special technology can be used to measure blood flow and oxygen in the brains of newborn babies. The researchers are comparing babies with bleeding in their brains or swelling in their heads to healthy babies. They think that problems with how the brain uses energy might be a better way to tell how bad the bleeding or swelling is and how well treatment is working. The study has been approved by a hospital review board and is being done at different hospitals. Pei-Yi Lin is in charge of the study and is getting funding from the National Institute of Health.

Trial Summary
This study uses frequency domain near-infrared spectroscopy coupled with diffuse correlation spectroscopy (FDNIRS-DCS) technology for monitoring cerebral blood flow (CBF) and cerebral oxygen metabolism (CMRO2) at the bedside for newborns with germinal matrix-intraventricular hemorrhage (GM-IVH) and/or post-hemorrhagic hydrocephalus (PHH) in comparison to newborns with hydrocephalus of a different etiology (VC) and healthy controls (HC). We hypothesize that baseline cerebral metabolic dysfunction is a better biomarker for GM-IVH and PHH severity and response to PHH treatment. This is a Boston Children's Hospital (BCH)-institutional review board(IRB) approved, multi-site study that includes collaboration with Brigham and Women's Hospital (BWH) and Beth Israel Deaconess Medical Center (BIDMC). Pei-Yi Lin receives funding from The National Institute of Health (NIH) to support the study and is the overall principal Investigator (PI) overseeing the study.

Enrollment Criteria

Third Opinion Criteria Synopsis
This is a study that focuses on four groups of babies. The first group is called GM-IVH group. Babies in this group were born between 24 and 32 weeks of pregnancy. They should be less than 3 months old or can be measured within 12 weeks after they turn 40 weeks old. These babies should have been diagnosed with grades I-III IVH (intraventricular hemorrhage) using a cranial ultrasound or MRI. Babies with certain conditions like chromosomal abnormalities, metabolic disorders, or CNS infection are not included in this group.The second group is called PHH group. Babies in this group were born between 24 and 37 weeks of pregnancy. They should be less than 3 months old or can be measured within 12 weeks after they turn 40 weeks old. These babies should have been diagnosed with PHH (post-hemorrhagic hydrocephalus) using a cranial ultrasound or MRI. Babies with certain conditions like chromosomal abnormalities, metabolic disorders, or CNS infection are not included in this group. They should not have any implanted devices or other devices that prevent the use of MRI.The third group is called HC group. Babies in this group were born between 24 and 32 weeks of pregnancy. They should be less than 3 months old or can be measured within 12 weeks after they turn 40 weeks old. These babies should have an Apgar score higher than 7 at 5 minutes after birth. Babies with brain injuries, chromosomal abnormalities, metabolic disorders, or critical congenital heart disease are not included in this group.The fourth group is called VC group. Babies in this group can be less than 12 months old or can be measured within 1 year after they turn 40 weeks old. These babies should have symptomatic hydrocephalus or be at high risk of developing hydrocephalus. They should not have any signs of IVH (intraventricular hemorrhage). Babies with certain conditions like metabolic disorders or CNS infection are not included in this group. They should not have implanted devices or other devices that prevent the use of MRI.
