Exposed to AnesthesiaNCT01229514
Functional Magnetic Resonance Imaging (fMRI) Findings in Children With Early Exposure to General Anesthesia
An observational study of Exposed to Anesthesia, run by Nationwide Children's Hospital at 1 site in United States.
Trial summary
General anesthetic medications have been shown to cause neuronal cell death in the brains of infant rodents. Ethanol and general anesthetics both act on NMDA and GABA receptors,and appear to have similar mechanisms of toxicity in the immature rodent brain. Read more about this study

About this study
Official title: A Comparison of Functional Magnetic Resonance Imaging (fMRI) Findings in Children With and Without a History of Early Exposure to General Anesthetics
General anesthetic medications have been shown to cause neuronal cell death in the brains of infant rodents. Ethanol and general anesthetics both act on NMDA and GABA receptors,and appear to have similar mechanisms of toxicity in the immature rodent brain. Functional MRI (fMRI) is a technique developed for mapping brain activation and has been utilized to examine how the brains of children with a history of early exposure to ethanol function differently from children without such a history. This study will utilize fMRI to look for specific changes in brain activation patterns in children with a history of early exposure to general anesthesia, as compared to children without such exposure.

Where is the study taking place?
The record lists 1 site in United States. 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?
Use of fMRI as a tool (time frame: one time 10 to 17 yrs. post-anesthesia). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT01229514, which also lists 2 linked publications.
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 2 Aug 2012; AzTrials last refreshed its copy on 8 Nov 2026.
