Trial summary

Moderate hypothermia has been demonstrated to be the effective treatment for neonates with hypoxic-ischemic encephalopathy (HIE). However, few studies reveal the actual alterations in physiological parameters (i.e. brain temperature and cerebral blood flow) of neonates undergoing cooling, especially for HIE lesions.

  • Ages 6 hours to 4 days
  • All sexes
  • No healthy volunteers
  • Child

Study population: Neonates with hypoxic-ischemic encephalopathy who fulfill the moderate hypothermia criteria

Who may be able to join

  • Neonates in the neonatal intensive care unit who fulfill the hypothermia criteria for treating the hypoxic ischemic encephalopathy and who are scheduled to have an MRI for evaluation of the extent of their injury.
  • Parents, clinicians and physician consent to perform evaluation of MRI before and during the hypothermia.

Who cannot join

  • Neonates too unstable to have MRI exam, defined by being more than 40% oxygen on the ventilator.
  • Hypothermia treatment interruption caused by potential factors.
  • Neonates with central nervous system infection,intracranial hemorrhage and brain parenchyma lesions caused by trauma.

About this study

Official title: Magnetic Resonance Imaging of Neonates With Hypoxic Ischemic Encephalopathy Before and During Moderate Hypothermia

Moderate hypothermia has been demonstrated to be the effective treatment for neonates with hypoxic-ischemic encephalopathy (HIE). However, few studies reveal the actual alterations in physiological parameters (i.e. brain temperature and cerebral blood flow) of neonates undergoing cooling, especially for HIE lesions. Therefore, this project aims to utilize the magnetic resonance imaging (MRI), i.e. MR thermal imaging and phase contrast MRI to measure the changes of these parameters before and during hypothermia; and then make comparisons with the routine nasopharyngeal and rectal temperature. All these would provide in vivo quantitative data for therapeutic evaluation and promote the optimization.

Read the detailed description
  1. Study objects 1.1 Primary object To examine the changes of brain temperature and cerebral blood flow in neonates with HIE before and during (i.e. cooling lasting for 24~36 hr) selective brain cooling. 1.2 Secondary object To compare the differences in temperature between brain (thalamus and HIE lesions) and nasopharynx and rectum of HIE neonates during the cooling.
  2. Methods Prospective observational study; the MR thermal imaging and phase contrast MRI will be used to estimate brain temperature and cerebral blood flow.

Neonates with HIE who fulfilled the moderate hypothermia criteria will be recruited from the neonatal intensive care units. MR scans will be performed twice after informed parental consent. The first scan will be before the hypothermia and the second scan will be during the hypothermia. The first scan will be performed while the neonate is still in the intensive care unit. At the time of the second MR scan, the neonate is still in the intensive care unit, and the neonate in hypothermia group is receiving the brain selective cooling. Sedation would be used if required in these babies.

Questions about this trial

What is this clinical trial studying?

An observational study of Hypoxic-Ischemic Encephalopathy, run by First Affiliated Hospital Xi'an Jiaotong University at 1 site in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 14 Mar 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Chao Jin, Phd (jinny.369@163.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Cooling-induced changes in brain temperature and cerebral blood flow (time frame: before and during (cooling lasting for 24~36 hr) the hypothermia). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 14 Mar 2017.
