Expiratory ventilation assistance versus pressure-controlled ventilation with ambient oxygen in a hemorrhagic trauma model: a prehospital rescue option?

ABSTRACT:

Background

Prehospital airway management is critical for maintaining oxygenation after severe trauma hemorrhage. In cases of semi-obstructed airways, intubation with an endotracheal tube may fail, whereas a 14 French intubating catheter may provide an alternative for ventilation. Expiratory ventilation assistance (EVA) through such a catheter could serve as a prehospital rescue option, particularly when oxygen supply is limited. This study evaluates whether EVA with ambient air is sufficient to maintain oxygenation and compares its effectiveness with pressure-controlled ventilation (PCV).

Methods

Twenty-three anesthetized swines (mean weight 58.3 kg, SD 4.6) were subjected to 32% blood volume hemorrhage and allocated to either EVA (n = 11) or PCV (n = 12). Historical data we
