Success of Laryngeal Mask Airway (LMA) Insertion During Continuous Chest Compressions in Neonatal Resuscitation: A Randomized Crossover Simulation Study

The purpose of this study is to evaluate the time required for laryngeal mask airway (LMA) insertion, first-attempt success rates, and airway sealing quality (air leak) during neonatal resuscitation with and without interrupting chest compressions. Standard resuscitation guidelines recommend pausing chest compressions for airway interventions due to the difficulty of inserting devices during physical movement. However, interrupting compressions drops coronary and cerebral perfusion. This study tests whether an LMA can be successfully inserted without pausing compressions in a high-fidelity simulation model. A total of 32 anesthesiologists participate in this randomized, crossover simulation study using a high-fidelity neonatal manikin. Participants perform two different scenarios in a randomly allocated order: Scenario A involves standard LMA insertion with interrupted chest compressions, and Scenario B involves LMA insertion during continuous, uninterrupted chest compressions. The primary objective is to determine if performing the procedure under continuous chest compressions affects the procedure time, clinical success, air leak volumes, or the perceived workload and stress of the practitioners.
