Magnetic resonance imaging (MRI) provides key clinical and diagnostic information for care of neonates and young infants. However, to obtain quality images, they need to be motionless in the scanner, often with the aid of sedation medications, which put them at risk for complications. An immobilizer device (an airtight, chambered device that safely and securely fastens around the infant without applying pressure) allows the infant to feel snug and warm, sleepy and motionless, and can be used as an alternative to sedation for this population. We conducted a retrospective, descriptive, comparative study at The Children¡¯s Hospital of Philadelphia MRI Department in the Division of Radiology. Inclusion criteria were infants less than or equal to 90 days of age, weighing at least 2 kg, requiring a MRI brain scan that is predicted to take no more than 60 min to complete. We obtained data on 36 patients who received sedation medications for their brain MRI scan, and 36 patients who completed their brain MRI scan without the use of sedation medication, but rather were in the ¡°feed and immobilize¡± group. Results of the study showed that brain MRIs on sedated infants took longer, and those infants were more likely to experience oxygen desaturation and require supplemental oxygen post-MRI. Most importantly, we found that the MR images were considered diagnostic in 100 % of the sedated infants and 94 % of the immobilized infants, although significantly more immobilized infants had artifact from motion than sedated infants. Implications for practice include potential cost saving and increased patient¡¯s safety (e.g., more stable respiratory status).
