Question

The adrenaline dose (1:10000 dilution) recommended in the Neonatal Resuscitation Program (NRP) is:

• A. 0.2 mL/kg
• B. 0.3 mL/kg
• C. 0.4 mL/kg
• D. 0.5 mL/kg

Hint:

NRP 8th Edition Epinephrine Dosing Rules:
- Concentration: 1:10,000 ($0.1\text{ mg/mL}$).
- IV IO Route (Preferred): $0.02\text{ mg/kg} = \mathbf{0.2\text{ mL/kg}}$ (range: $0.1\text{--}0.3\text{ mL/kg}$), followed by normal saline flush.
- Endotracheal Route: $0.1\text{ mg/kg} = \mathbf{1.0\text{ mL/kg}}$ (range: $0.5\text{--}1.0\text{ mL/kg}$).

Answer 1

The Correct Option is A

Concept:
In the Neonatal Resuscitation Program (NRP 8th Edition AAP AHA guidelines), Epinephrine (Adrenaline) is indicated if the neonate's heart rate remains strictly below 60 beats per minute ($< 60\text{ bpm}$) despite at least 60 seconds of coordinated effective positive pressure ventilation (PPV) with 100% oxygen and chest compressions.
Explanation:
• The concentration of epinephrine used in neonatal resuscitation is exclusively the 1:10,000 dilution (0.1 mg/mL).

• The recommended intravenous (IV) or intraosseous (IO) dose of 1:10,000 epinephrine is 0.02 mg/kg, which corresponds mathematically to an injection volume of 0.2 mL/kg (acceptable range: $0.01\text{ to }0.03\text{ mg/kg}$, equivalent to 0.1 to 0.3 mL/kg).

• Intravenous or intraosseous administration is the preferred and most effective route of delivery, followed immediately by a $0.5\text{ to }1.0\text{ mL}$ normal saline flush.

• If umbilical venous access is being established, an endotracheal (ET) dose may be given as a temporary bridge: the ET dose is significantly higher at 0.05 to 0.1 mg/kg (equivalent to 0.5 to 1.0 mL/kg of 1:10,000 solution) due to unreliable pulmonary absorption.

• Thus, for the standard IV/IO route, the targeted single bolus volume of 1:10,000 dilution is 0.2 mL/kg.
Final Answer:
The recommended intravenous dose volume of 1:10,000 dilution epinephrine in the Neonatal Resuscitation Program is 0.2 mL/kg (0.02 mg/kg).
