The National Institute of Neurological Disorders and Stroke, part of the National Institutes of Health, is looking for individuals to participate in clinical studies. Participating in clinical trials allows you to play an active role in research on the nature and causes of many disorders of the brain and nervous system, and to possibly help physician-scientists develop future treatments. The information below is designed to help you quickly learn about actively recruiting research studies for which you or someone you know may be eligible.

Description:

This is a prospective, single-center, data collection research study for premature ELBW infants at high risk of developing brain injury. This study is being done to evaluate the changes in brain perfusion measured by the DCM using a comprehensive and innovative brain monitoring platform that encompasses direct and continuous measures of cerebral blood flow (CBF), cerebral oximetry, cerebral autoregulation, partial pressure of carbon dioxide (PCO2), and arterial blood pressure (ABP) in the hopes to both describe the physiology of brain injury and to correlate these findings to short- and long-term outcomes relevant to ELBW infants. About three hundred and ten (310) subjects are expected to be enrolled. Subjects' active participation in the study may last up to one week and the total time they will be followed after birth is approximately 24 months (2 years) depending on their prematurity. Information from the subjects' medical records may be accessed, reviewed, and recorded for an additional year after their final study visit. This study consists of about 5 study visits: Study Visit 1 (the enrollment visit), Study Visit 2 (occurs 2-7 days after the enrollment visit), Study Visit 3 (occurs approximately 2-4 months after the enrollment visit), Study Visit 4 (occurs approximately at 12 months after the enrollment visit), and Study Visit 5 (occurs approximately at 24 months after the enrollment visit). STUDY ASSESSMENTS: - Medical and Surgical History: The subjects' detailed history will be reviewed and recorded. The subjects' mothers will also be asked questions about their own medical history. The mothers' medical records may also be accessed. - Continuous Physiologic Monitoring: Monitoring will be performed that includes the transcranial Doppler ultrasound, near-infrared spectroscopy (NIRS), and partial pressure of carbon dioxide (PCO2) from birth to 7 days of life (visits 1 and 2). - Ventilator: The highest daily ventilator settings and mean airway pressure (MAP) will be reviewed and recorded from birth to 7 days of life (visits 1 and 2). - Head Ultrasound: A head ultrasound will be performed upon enrollment (visit 1) to assess for early and preexisting brain injury (IVH). - Adverse Events: Any adverse events (AEs), special events of interest, or unanticipated problems (UPs) that subjects may have experienced after enrollment will be reviewed and recorded (visits 1, 2, 3, 4, and 5). - Concomitant Medications: Review and record any medications of interest that subjects are taking from birth to 7 days of life (visits 1 and 2). - Blood Transfusions: Review and record the transfusion of blood products that are performed on the subjects as part of standard of care from birth to 7 days of life (visits 1 and 2). - Echocardiogram (ECG) and Head Ultrasound: Review and record ECG and head ultrasound results that are performed on the subjects as part of standard of care from birth to 7 days of life (visits 1 and 2). - Respiratory Interventions and Suctioning: Review and record any respiratory interventions and/or suctioning that are performed on the subjects as part of standard of care from birth to 7 days of life (visits 1 and 2). - Magnetic Resonance Imaging (MRI): Perform a MRI exam at visit 3. - Capute Scales and Neurologic Exam: Perform this assessment at visit 4 to assess the subjects' development and cognitive function and to provide an early evaluation for any neurologic abnormalities that may be related to brain injury. - Bayley-III Motor Sub-Test Exam: Perform this assessment at visit 4 to assess the subjects' development and cognitive function and to provide an early evaluation for any neurologic abnormalities that may be related to brain injury. - Complete Bayley-III Exam: Perform this assessment at visit 5 to assess the subjects' development and cognitive function and to provide an early evaluation for any neurologic abnormalities that may be related to brain injury.
