What is Pediatric MRI Without Anesthesia — Feed and Wrap Technique?

Feed and wrap is a non-pharmacologic technique that uses post-prandial natural sleep in young infants to obtain diagnostic-quality MRI without sedation or general anesthesia. It is most effective up to about 4-6 months of age, when the infant has predictable feed-sleep cycles and limited spontaneous movement.

Preparation includes a controlled fasting period followed by a generous feed, swaddling with appropriate hearing protection, careful temperature control and immobilization devices such as MedVac bags. Optimized fast MRI sequences (single-shot, motion-resistant techniques) and a quiet, dim environment increase success rates above 80-90%.

Advantages include avoidance of anesthetic-related neurodevelopmental concerns, shorter recovery, reduced cost, and earlier discharge. Limitations include the need for highly cooperative infants, longer set-up, and a fail-back plan with rescue sedation for incomplete studies.

Symptoms

Indications: brain, spine and abdominal MRI in infants
Suspected neurologic abnormality
Congenital cardiac MRI evaluation
Hip dysplasia or musculoskeletal imaging
Follow-up of neonatal neuroimaging
Avoidance of anesthesia in selected patients
Daycase pediatric MRI workflow

Risk Factors

Age under 4-6 months
Stable cardiopulmonary status
Predictable feeding schedule
Cooperative parental preparation
Quiet imaging environment availability
Trained pediatric imaging team
Fast MRI sequences in protocol

When to See a Doctor?

If you experience any of the following symptoms, seek medical attention promptly:

  • Need for sedation versus feed-and-wrap selection
  • Family preference for non-anesthesia option
  • Failed prior MRI with motion artifact
  • Cardiopulmonary risk factors for anesthesia
  • Long anticipated MRI sequences

Treatment Methods

02
Swaddling with hearing protection
03
Temperature and immobilization control
04
