Which of the following is a common cause of cardiac arrest in children and infants?

Answer: Cardiac arrest in children and infants is a serious medical emergency. Unlike adults, where cardiac arrest is often related to heart disease, the causes in younger populations can vary significantly. Key causes include:

  1. Respiratory Problems

    • Explanation: Respiratory distress and failure are the most common causes of cardiac arrest in children and infants. This can be due to conditions such as bronchiolitis, asthma, pneumonia, or foreign body airway obstruction. When the respiratory system fails to provide adequate oxygenation, it can lead to cardiac arrest.

  2. Congenital Heart Defects

    • Explanation: Some children are born with congenital heart defects which can lead to cardiac arrest. These defects affect the heart’s structure and function, necessitating early detection and management to prevent severe consequences.

  3. Arrhythmias

    • Explanation: Abnormal heart rhythms or electrical disturbances within the heart can result in cardiac arrest. These arrhythmias can sometimes be congenital or arise due to other underlying conditions.

  4. Trauma

    • Explanation: Severe trauma, such as from car accidents, falls, or non-accidental injuries (abuse), can lead to cardiac arrest. Injury to the heart or a significant loss of blood can compromise heart function.

  5. Sudden Infant Death Syndrome (SIDS)

    • Explanation: Although the exact cause of SIDS is not fully understood, it is a leading cause of cardiac arrest in infants under one year of age. It is often unexplained and occurs usually during sleep.

  6. Toxin or Poisoning Exposure

    • Explanation: Ingestion of harmful substances, whether accidental or intentional, can lead to cardiac arrest. This includes medications, household chemicals, and illicit drugs.

  7. Electrolyte Imbalances

    • Explanation: Imbalances in electrolytes such as potassium, calcium, and magnesium can disrupt the electrical activity of the heart and cause cardiac arrest. This can occur due to dehydration, kidney failures, or other metabolic disorders.

  8. Sepsis

    • Explanation: Severe infections leading to sepsis can cause systemic inflammation, septic shock, and cardiac arrest. Infants and children are particularly vulnerable due to their less mature immune systems.

Final Answer: The most common cause of cardiac arrest in children and infants is respiratory problems. However, other causes like congenital heart defects, arrhythmias, trauma, SIDS, toxin exposure, electrolyte imbalances, and sepsis also significantly contribute to the occurrence of cardiac arrests in this population.

For a nuanced understanding, it’s critical to get proper medical attention and diagnostic evaluation to address and prevent potential causes of cardiac arrest in children and infants.
