Ventilation efficacy during paediatric cardiopulmonary resuscitation (PEDIVENT): simulation-based comparative study.

Area of Science:

• Resuscitation science
• Pediatric emergency medicine
• Cardiopulmonary resuscitation techniques

Background:

• Effective ventilation is crucial in pediatric cardiopulmonary resuscitation (CPR), as most cardiac arrests stem from hypoxia.
• Current European Resuscitation Council (ERC) guidelines recommend initial breaths before chest compressions, but this is based on expert consensus without robust evidence.
• A knowledge gap exists regarding the efficacy of ventilation during pediatric CPR by both healthcare professionals (HCPs) and lay rescuers (LRs).

Purpose of the Study:

• To evaluate and compare the efficacy of ventilation during pediatric CPR provided by HCPs and LRs.
• To assess the number of effective breaths delivered during the initial sequence of CPR in a simulation setting.
• To determine the impact of structured CPR training on ventilation effectiveness in both HCPs and LRs.

Main Methods:

• A simulation-based study involving 90-second CPR sequences on 5-kg Baby and 20-kg Junior mannequins.
• Participants included HCPs using bag-mask ventilation and LRs performing dispatcher-assisted CPR with mouth-to-mouth ventilation.
• Ventilation efficacy was assessed before and after structured CPR training for both groups.

Main Results:

• Significant improvements in reaching the primary outcome (effective ventilation) were observed post-training for both HCPs and LRs on the Baby mannequin (p < 0.001).
• For the Junior mannequin, LRs showed a significant improvement in effective ventilation post-training (p = 0.005), while HCPs showed a non-significant improvement (p = 0.77).
• Trained HCPs and LRs demonstrated the ability to deliver effective ventilation to pediatric mannequins.

Conclusions:

• This study provides the first evidence on ventilation efficacy in pediatric CPR by HCPs and LRs using simulation.
• The findings support the ERC guideline concept of initiating pediatric CPR with breaths, particularly when delivered by trained individuals.
• Structured training enhances ventilation effectiveness, suggesting its importance for improving pediatric resuscitation outcomes.
