    General endotracheal anesthesia using enflurane or halothane is most effective for pediatric cerebral computer tomography. This method ensures patient immobility, preventing motion artifacts and improving airway control for clearer brain imaging.

    Area of Science:

    • Neuroradiology
    • Medical Imaging

    Background:

    • Cerebral computer tomography (CT) provides tomographic x-rays of brain sections.
    • Immobility is crucial for diagnostic accuracy, often necessitating anesthesia in pediatric and uncooperative adult patients.

    Purpose of the Study:

    • To evaluate the efficacy of different anesthetic techniques for pediatric cerebral computer tomography.
    • To identify the optimal anesthetic approach for minimizing motion artifacts and ensuring patient safety.

    Main Methods:

    • Retrospective analysis of 84 cerebral CT procedures performed under general anesthesia.
    • Comparison of anesthetic agents including ketamine, chloral hydrate, enflurane, halothane, and various sedatives.
    • Assessment of airway management and motion artifact control for each technique.

    Main Results:

    • Ketamine and heavy sedation proved unsatisfactory due to airway issues and unpredictable motion, leading to image artifacts.
    • General endotracheal anesthesia with enflurane or halothane in N2O-O2 mixture was highly satisfactory.
    • Inhalational anesthesia provided superior airway control and motion prevention compared to other methods.

    Conclusions:

    • General endotracheal anesthesia with halothane or enflurane is the preferred method for pediatric cerebral computer tomography.
    • This technique optimizes image quality by ensuring immobility and maintaining airway patency.
