Intranasal Midazolam Dosing for Procedural Sedation

Dosing Considerations

For procedural sedation in a 14.8kg 5-year-old male, the recommended intranasal midazolam dose is 0.2-0.3 mg/kg (approximately 3-4.4 mg total dose) 1
For children under 6 years old, higher doses of oral midazolam (up to 1 mg/kg) may be required compared to older children, suggesting that younger children may need doses at the higher end of the recommended range 1
The standard dosing range for midazolam when used for sedation/anxiolysis is:
- IV: 0.05-0.10 mg/kg given over 2-3 minutes (maximum single dose: 5 mg) 1
- PO: 0.25-0.50 mg/kg (maximum: 20 mg) 1
- For intranasal administration, doses similar to IM dosing (0.2 mg/kg) are appropriate 1

Continuous monitoring of oxygen saturation via pulse oximetry is essential during procedural sedation 2
Capnography is valuable to detect respiratory depression or airway obstruction earlier than pulse oximetry alone 2
Paradoxical agitation may occur, especially in younger children 1

Have resuscitation equipment readily available including supplemental oxygen and airway management tools 2
Flumazenil (benzodiazepine antagonist) should be available to reverse severe respiratory depression if needed, though it may also reverse the anticonvulsant effects 1
The sedation failure rate with midazolam is approximately 1-2%, so have a backup sedation plan available 3

Recovery time is significantly shorter than with other sedatives such as pentobarbital 4
