Insights
New automated external defibrillators (AEDs) are now available for pediatric use, addressing previous concerns about energy delivery and device compatibility. Further trials are needed to confirm improved outcomes for children experiencing cardiac arrest.
Area of Science:
- Pediatric Emergency Medicine
- Cardiovascular Resuscitation Technology
Background:
- Automated external defibrillators (AEDs) have been used for adults for over two decades.
- Pediatric use of AEDs was limited due to concerns regarding energy delivery, waveform effects, pad size, and rhythm detection.
- International Liaison Committee on Resuscitation (ILCOR) approved pediatric AED use in June 2003.
Purpose of the Study:
- To describe advances in AED technology for pediatric use.
- To highlight new recommendations for pediatric AEDs.
- To identify the need for further clinical trials on pediatric AED effectiveness.
Main Methods:
- Review of technological advancements in automated external defibrillators for pediatric application.
- Analysis of new data regarding pediatric AED performance and safety.
- Description of changes leading to updated ILCOR recommendations.
Main Results:
- New generation AEDs can safely identify pediatric shockable and non-shockable rhythms.
- These devices deliver fixed, lower energy shocks via appropriately sized pads.
- Encouraging data supports the safety and efficacy of newer pediatric AEDs.
Conclusions:
- Recent technological improvements have addressed previous limitations of AEDs in children.
- New AEDs are designed to better suit pediatric resuscitation needs.
- Randomized clinical trials are essential to determine if these pediatric devices improve cardiac arrest outcomes.
Abstract:
Although automated external defibrillators (AEDs) have been available for adults for more than 20 years, their use in children under 8 years of age has been approved by the International Liaison Committee on Resuscitation (ILCOR) as recently as June 2003. The following concerns about AEDs limited their use in children: amount of delivered energy, effect of biphasic waveforms in children, pad size, and capacity of detecting pediatric shockable and non-shockable rhythms. Lately, a new generation of AEDs addressed these issues and new encouraging data are available. New AEDs safely identify pediatric shockable and non-shockable rhythms and deliver fixed lower energy shocks through pads of appropriate size. This perspective briefly describes the main advances which heralded the new recommendations of ILCOR. Randomized clinical trials are now needed to identify whether these new pediatric devices can improve the outcome of pediatric cardiac arrest.
