Cardiac arrest is a rare occurrence in the pediatric population. When it does occur, the outcome can be devastating. Death may result or if the patient is resuscitated, permanent brain damage is possible. The etiology of cardiac arrest in a child differs from an adult. Cardiac arrest in the pediatric patient is the result of prolonged respiratory depression and apnea. These situations are often associated with local anesthesia toxicity as a result of overdose or intravascular injection and with the administration of CNS depressant drugs for behavior management.
Comprehensive BLS training is not within the scope of the course and it is recommended the reader seek out formal BLS instruction. Because the etiologies for cardiac arrest differ for adults (cardiac disease) and children (depleted oxygen in the myocardium) differ, the 2010 American Heart Association guidelines for BLS differ.
For unwitnessed and witnessed cardiac arrests with two or more rescuers present, assess the patient, initiate CPR, activate the emergency response system and obtain an automated external defibrillator (AED) simultaneously.
For the lone rescuer, the sequence varies:
Comprehensive CPR training is not within the scope of this course, and it is recommended the reader seek out formal BLS instruction. It is important for BLS providers to realize because of different etiologies for cardiac arrest in adults (cardiac disease) and children (depleted oxygen in the myocardium) there is a significant difference in BLS protocols for adults and children.
In adults, after initial assessment of the unresponsive patient, EMS is activated immediately (before starting BLS) so access to trained personnel and defibrillation equipment is available as soon as possible. In children, since the likely cause of cardiac arrest is lack of oxygen in cardiac muscle, BLS is started immediately and EMS is contacted after delivery of BLS for 2 minutes. If two rescuers are present, one starts BLS while the other activates EMS and obtains the defibrillation equipment.16,17
