For vagal maneuvers using ice packs on newborns, what is the recommended duration for each application?

• A. 5 seconds
• B. 10 seconds
• C. 15 seconds
• D. 30 seconds

Answer: (C)

When trying vagal maneuvers in a newborn, the goal is to provoke a brief vagal (parasympathetic) response by a cold facial stimulus. Applying an ice pack to the face for about 15 seconds provides a strong enough trigger to slow the heart rate and AV conduction without keeping the stimulus on too long. If you use too short a duration, the reflex may not be reliably elicited; too long a duration increases the risk of excessive bradycardia, apnea, or skin injury and can delay further treatment. After the application, reassess the infant’s heart rate and rhythm and continue with the appropriate management if the SVT persists, ensuring safety and ongoing monitoring.
