Factors Associated With Successful Completion of MRI in Children Undergoing a Vigil Sedation With Dexmedetomidin

This study looks at how well Dexmedetomidine (DEX) works for calming kids before they have an MRI scan. An MRI is a special picture of the brain taken inside a big machine. Kids need to stay very still, which can be hard, especially for those under 5 or with autism or other challenges. Normally, doctors use a strong sleep medicine called propofol, but it can be uncomfortable because it requires a tube to help with breathing. DEX is a gentler medicine given through the nose and has been shown to work well without the need for tubes. However, we don’t know if it works better or worse for different groups of kids, such as those with autism or epilepsy.

• This study is about looking back at past cases, so no new visits or treatments are needed for participants.
• It includes kids under 18 who had an MRI with DEX, but not if their medical records are incomplete.
• The study aims to help improve MRI sedation practices for all kids.
