If a child becomes bradycardic, what is the first-line drug to administer?

• A. Adrenaline
• B. Vagolytic (atropine)
• C. Calcium gluconate
• D. Amiodarone

Answer: (B)

In the case of a child experiencing bradycardia, the first-line drug to administer is a vagolytic agent, specifically atropine. Atropine works by blocking the action of the vagus nerve on the heart, which effectively increases the heart rate. This mechanism is particularly useful in pediatric patients, where vagal stimulation can often lead to bradycardia. Atropine is generally recommended as the initial treatment due to its rapid onset and ease of administration in emergency situations. In contrast, other agents listed, such as adrenaline and amiodarone, may be utilized in specific scenarios but are not the first choice for addressing bradycardia in children. Calcium gluconate, while important in managing calcium deficiencies or hyperkalemia, does not directly treat bradycardia. Therefore, atropine stands out as the appropriate agent for this specific condition in pediatric patients.
