Dose ranges
Totals use the formulas above. Verify local dose caps and formulations.
Measured weight: Use the child’s current measured weight when available. For a weight between rows, calculate from the formula rather than rounding. Use neonatal references for newborn-resuscitation care.
Atropine is selective, not routine. Verify indication, age-specific maximum, local concentration, and pediatric pharmacy guidance.

Major cautions
- Atropine
- May be considered in selected infants and children; not routine for every emergency intubation.
- Fentanyl
- Analgesia reference. Administer slowly and verify local pediatric maximum and concentration.
- Midazolam
- Sedation reference, not an analgesic. U.S. labeling uses age-specific initial doses and provides limited guidance for infants younger than 6 months; verify age, indication, cumulative sedatives, and the local maximum.
