Trial summary

Cardiac surgery under extracorporeal circulation (ECC) in newborns with congenital heart disease causes significant morbidity and mortality. The perioperative period is a period of major vulnerability implicated in the appearance of these sequelae, and it is therefore essential to monitor brain function during ECC.

About this study

Cardiac surgery under extracorporeal circulation (ECC) in newborns with congenital heart disease causes significant morbidity and mortality. The perioperative period is a period of major vulnerability implicated in the appearance of these sequelae, and it is therefore essential to monitor brain function during ECC. The quality of cerebral oxygenation in the perioperative period is routinely monitored non-invasively by infra-red spectroscopy, which makes it possible to estimate cerebral tissue oximetry from a surface electrode (NIRS). The association between time spent outside the limits of cerebral autoregulation and the occurrence of perioperative encephalopathy is not known. The purpose of this study is to determine whether disturbances in brain autoregulation during the operative period are associated with the occurrence of postoperative encephalopathy in children operated on for congenital heart disease in the neonatal period. The main objective of the research is to determine the association between time spent outside individually determined cerebral autoregulation limits and the appearance of brain lesions suggestive of low brain output. Secondary objectives will investigate the association between time spent outside autoregulatory limits and the occurrence of postoperative encephalopathy defined by clinical and encephalographic criteria and will study factors predictive of the development of postoperative encephalopathy.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. determine the association between time spent outside individually determined cerebral autoregulation limits and the development of brain lesions suggestive of low brain output.

    duration of period outside cerebral autoregulation limits, Number, size and extent of new lesions on post-operative MRI.

    Patients will be classified into 2 categories according to whether or not there are new lesions on MRI.

    The lesions retained will be infarcts, white matter lesions and intraparenchymal hemorrhages, classified according to the Magnetic Resonance Imaging Abnormality Scoring System.

    Measured: 6 weeks after cardiac surgery

Secondary outcomes (7)
  1. describe association between time spent outside autoregulation limits and the occurrence of postoperative encephalopathy defined by clinical and encephalographic criteria.

    duration of period outside cerebral autoregulation limits, Standardized clinical examination according to Amiel Tison at hospital discharge.

    Measured: 6 weeks after cardiac surgery

  2. describe predictive factors of postoperative encephalopathy

    duration of extra-corporal circulation,

    Measured: day 1 (cardiac surgery)

  3. describe predictive factors of postoperative encephalopathy

    duration of aortic clamp

    Measured: day 1 (cardiac surgery)

  4. describe predictive factors of postoperative encephalopathy

    duration of selective cerebral perfusion,

    Measured: day 1 (cardiac surgery)

  5. describe predictive factors of postoperative encephalopathy

    duration of hypothermia deepness

    Measured: day 1 (cardiac surgery)

  6. describe predictive factors of postoperative encephalopathy

    duration of critical NIRS

    Measured: day 1 (cardiac surgery)

  7. describe predictive factors of postoperative encephalopathy

    duration of critical median arterial pression (PAM)

    Measured: day 1 (cardiac surgery)

Questions about this trial

What is this clinical trial studying?

A study testing MRI in people with Congenital Heart Disease in Children and Extracorporeal Circulation; Complications, run by Nantes University Hospital at 1 site in France.

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 1 inclusion and 8 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: finished, as of the sponsor's last update on 29 Jul 2024. 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 France. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

determine the association between time spent outside individually determined cerebral autoregulation limits and the development of brain lesions suggestive of low brain output. (time frame: 6 weeks after cardiac surgery). 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 29 Jul 2024.
