Superiority of the Bag-Valve-Guedel Adaptor Over the Standard Face Mask for Preintubation Ventilation of Bearded Patients by Trainees With Limited Experience: Prospective Controlled Cross-Over Clinical Trial.

ABSTRACT:

Objectives

Ventilation of bearded patients using the standard face mask (FM) is often difficult, particularly in field settings and mass casualty events. The current study compares the effectiveness of a novel Bag-Valve-Guedel Adaptor (BVGA) with the standard FM when applied to anesthetized patients by anesthesiology trainees with limited experience.

Methods

Male patients scheduled for elective surgery (American Society of Anesthesiology physical score 1-2) were recruited for this prospective, randomized, cross-over trial. Beard length was categorized as <0.5 cm (none/stubble), 0.5 to 1 cm, 1 to 5 cm, or ≥5 cm. Anesthetized patients were ventilated by anesthesiology trainees using the BVGA and an FM. The main outcome included end-tidal CO₂, expiratory tidal volume
