Trial summary

The demand for magnetic resonance imaging (MRI) in pediatric patients is increasing due to its use in medical diagnosis and surveillance. Pediatric patients often require general anesthesia (GA) for MRI due to the need for prolonged immobility during the scanning process to obtain high quality images. Read more about this study

About this study

Official title: Neurobiological, Cognitive-affective and Behavioral Changes Following Exposure to Either Sevoflurane- or Propofol-based Anesthesia in Children Undergoing MRI

The demand for magnetic resonance imaging (MRI) in pediatric patients is increasing due to its use in medical diagnosis and surveillance. Pediatric patients often require general anesthesia (GA) for MRI due to the need for prolonged immobility during the scanning process to obtain high quality images. Two widely used anesthetic techniques for pediatric MRIs are volatile-based anesthesia using sevoflurane and total intravenous anesthesia (TIVA) using propofol. Concerns have been raised regarding the potential neurotoxic effects of anesthetics on the developing brain. Within the animal literature, there is emerging evidence to suggest that both sevoflurane and propofol may cause inflammation, impacting brain cell survival and connections, thereby contributing to possible cognitive dysfunction. However, given the challenges in extrapolating the animal data to humans, and the relatively limited human cohort studies examining the long-term effects of anesthesia exposure, there is inadequate information available to make informed clinical decisions regarding the choice of optimal anesthetic agents for MRI in children. Therefore, this study will uniquely examine the mechanisms of two widely used anesthetics and their short and long-term impact on developmental outcomes in healthy children.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • PropofolDrug

    The child will be randomized via a block design to receive either a volatile anesthetic (induction: sevoflurane), or total intravenous anesthetic technique (induction: propofol)

  • SevofluraneDrug

    The child will be randomized via a block design to receive either a volatile anesthetic (induction: sevoflurane), or total intravenous anesthetic technique (induction: propofol)

  • AmetopDrug

    Each patient will receive Ametop local anesthetic to the dorsum of both hands 30-45 minutes prior to induction.

  • OndansetronDrug

    Each patient will receive the antiemetic ondansetron 0.1mg/kg IV.

Study groups in NCT03022240
Study groupRoleWhat they receive
Inhalational TechniqueExperimentalAll patients will receive Ametop local anesthetic to the dorsum of both hands 30-45 minutes prior to induction. After inhalation induction of anesthesia with sevoflurane (in 100% O2), an IV will be obtained. Anesthesia will be maintained with sevoflurane (in a mixture of air:oxygen) with a minimum alveolar concentration of 1.0-1.3, titrated to effect. No long acting opioids or nitrous oxide will be used. Airway management will be at the discretion of the anesthesiologist. Each patient will receive the antiemetic ondansetron 0.1mg/kg IV.
Receives: Drug: Sevoflurane; Drug: Ametop; Drug: Ondansetron
Total Intravenous Anesthetic TechniqueExperimentalAll patients will receive Ametop local anesthetic to the dorsum of both hands 30-45 minutes prior to IV insertion. Once an IV is established, patients will receive an IV bolus of propofol (2-6mg/kg). Anesthesia will be maintained with a propofol infusion starting at 250 mcg/kg/min and titrated to effect. Airway management will be at the discretion of the anesthesiologist. Each patient will receive the antiemetic ondansetron 0.1mg/kg IV.
Receives: Drug: Propofol; Drug: Ametop; Drug: Ondansetron

What is being measured

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

  1. Wechsler Preschool and Primary Scale of Intelligence (WPPSI-IV)

    The WPPSI - IV is designed for children aged 2.5 to 7.5 years, and is used to assess general intelligence.

    Measured: 12-15 weeks from date of randomization

Secondary outcomes (1)
  1. The Child Behavior Checklist (CBCL) 1.5 to 5 years

    The CBCL is widely used for identifying problem behaviors in children ages 1.5 to 5 years

    Measured: Change from baseline at 12-13 weeks after randomization

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Propofol, Sevoflurane and Ametop in people with Cognitive Change and Behavior, run by University of Calgary at 1 site in Canada.

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 9 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 26 Mar 2020. 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 Canada. 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.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

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?

Wechsler Preschool and Primary Scale of Intelligence (WPPSI-IV) (time frame: 12-15 weeks from date of randomization). 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 26 Mar 2020.
