Electronic Pediatric Emergency Ruler vs the Broselow Tape.

Time Until Identification of Defined Parameter

Weight estimation, Patient safety

Comparison of two different pediatric emergency rulers for length-based body weight estimation in pediatric emergencies. Primary outcome is the time needed to identify four defined parameters from the pediatric emergency rulers during a low-fidelity pediatric emergency scenario (cardiac arrest). Secondary outcome is the correctness of the identified parameters and the percentage deviation from the correct value.

Medical team members (Paramedics, EMT) of Schutz und Rettung Zurich, Zurich Switzerland were asked to participate in this study. If they were not familiar with one of the three devices written informed consent was obtained and the participant included in this study. This exclusion criteria was necessary to prevent a bias by already knowing where to find the information of interest. The pediatric emergency rulers investigated were the electronic Pediatric Emergency Ruler (ePER) and the Broselow Tape (BT) All participants were instructed for the use of the two pediatric emergency rulers and were given time to practice with each device using one training manikin (Sim-Baby) After they felt comfortable using the devices the participants were randomly assigned to use each device only once with one of two different manikins: Resusci Baby, Laerdal/Dräger Medical Switzerland AG, Liebefeld, Switzerland Ambu® Junior, Ambu® GmbH, Bad Nauheim, Germany Each manikin was only used once for the same participant. This guaranteed that the participants were blinded for the manikins. The low-fidelity pediatric emergency scenario simulated was a cardiac arrest and the participants were asked to identify the following information from the pediatric emergency rulers: Estimated body weight Joule suggested for defibrillation Recommended epinephrine dose Suggested endotracheal tube size Participants stood aside from the manikin with a pediatric emergency ruler in their hand. After they stated they were ready, the facilitator started a countdown from three and gave the command to start. This setting was identical for all two pediatric emergency rulers and all two manikins. The time until each parameter was identified and the value of the parameter were recorded. Primary outcome was the time needed to identify the four above defined parameters. Secondary outcome was the correctness of the identified parameters and the percentage deviation from the correct value.
