What is the appropriate adrenaline dosage for treating anaphylaxis in a 12-month-old?

The appropriate dosage of adrenaline for treating anaphylaxis in a 12-month-old is indeed 0.01 mL/kg of 1:1000 solution administered intramuscularly. This dosage aligns with established pediatric guidelines, which recommend administering adrenaline at a concentration of 1:1000.

In this scenario, dosing is based on weight, and the correct concentration allows for effective management of anaphylactic reactions in young children. The 0.01 mL/kg dosage ensures that children receive a safe and effective amount of the medication without the risk of overdose, which is particularly critical in young patients who may have lower bodyweights.

Using any alternative concentrations or dosages would either provide insufficient treatment or risk harmful side effects. For instance, using a 1:10,000 concentration is inappropriate for non-cardiac arrest scenarios and could lead to underdosing. Hence, following the 1:1000 concentration and the recommended weight-based calculation guarantees appropriate and effective treatment in cases of anaphylaxis.
