A 3-year-old child is brought into the Emergency department with pulseless electrical activity.

Which one of the following is the correct dose of epinephrine (adrenaline) in these circumstances?

(Please select 1 option)

3 ml of 1:10,000

15 mcg of 1:1000

1.5 ml of 1:10,000 Correct

30 mcg of 1:1000

1.5 ml of 1:1000

Explanation

In paediatric cardiac arrest the dose of adrenaline is 10 micrograms per kilogram = 0.1 ml/kg of 1 in 10,000 solution.

Weight can be estimated using the formula:

2 × (age + 4), or

(3 × age) + 7

These formulae are asked about in both the written and structured oral examinations.

For a 3-year-old child these give 14 or 16 kg respectively. For a 15 kg child this equals 150 mcg, which is 1.5 ml of 1:10,000 of adrenaline.

1.5 ml is easiest to measure during a cardiac arrest so the correct dose would be 1.5 ml of 1:10,000 of adrenaline.
