Evaluation of telephone-cardiopulmonary resuscitation advice for paediatric cardiac arrest

Introduction

Telephone-cardiopulmonary resuscitation (CPR) advice aims to increase the quality and quantity of bystander CPR, one of the few interventions shown to improve outcome in cardiac arrest. We evaluated a current paediatric telephone protocol (AMPDS v11.1) to assess the effectiveness of verbal CPR instructions in paediatric cardiac arrest.

Methods

Consecutive emergency calls classified by the AMPDS as cardiac arrests in children <8 years old, over an 11 month period, were compared with their corresponding patient report forms (PRFs) to confirm the diagnosis. Audio recordings and PRFs were then evaluated to assess whether bystander CPR was given, and when it was, the time taken to perform CPR interventions, before paramedic arrival.

Results

Of the 42 calls reviewed, 19 (45.2%) were confirmed as cardiac arrest. CPR was already underway in two cases (10.5%). Of the remaining callers, 11 (64.7%) agreed to attempt T-CPR, resulting in an overall bystander-CPR rate of 68.4%. The median time to open the airway was 126 s (62-236 s, n = 11), deliver the first ventilation was 180 s (135-360 s, n  = 11), and perform the first chest compression was 280 s (164-420 s, n  = 9).

Conclusion

Although current telephone-CPR instructions improve the numbers of children in whom bystander CPR is attempted, effectiveness is likely to be limited by the significant delays in actually delivering basic life support.
