Healthcare providers often apply suboptimal paddle force during pediatric defibrillation. This study found that forces applied to infant and child manikins were frequently below recommended levels, potentially impacting defibrillation success.

Area of Science:

  • Pediatric Emergency Medicine
  • Cardiovascular Resuscitation
  • Medical Device Usability

Background:

  • Transthoracic impedance affects defibrillation success; optimal paddle force minimizes this.
  • Established optimal forces are 2.9 kgf for infants (<10 kg, pediatric paddles) and 5.1 kgf for children (>10 kg, adult paddles).

Purpose of the Study:

  • To compare actual defibrillation paddle forces used in simulated pediatric scenarios with established optimal values.
  • To assess adherence to recommended paddle force guidelines during pediatric defibrillation simulations.

Main Methods:

  • 72 healthcare professionals simulated pediatric defibrillation on infant and child manikins.
  • Paddle force was measured during simulated shocks using pediatric and adult paddles.
  • Applied forces were compared against known optimal values for different pediatric weight categories.

Main Results:

  • Median force for infant manikins was 2.8 kgf, with only 47% of operators achieving optimal force.
  • Median force for child manikins was 3.8 kgf, with only 24% of operators achieving optimal force.
  • Significant variability in applied paddle force was observed, with some exceeding 10 kgf.

Conclusions:

  • Paddle force applied during simulated pediatric defibrillation frequently falls below optimal levels.
  • Inconsistent application of recommended paddle force may compromise defibrillation efficacy in pediatric patients.
