López-Torres et al. Ventrain device for difficult or obstructed airway: 4 case report. Abstracts / Trends in Anesthesia and Critical Care 2017; 12:31

Dr. J. López-Torres and colleagues present four case reports of Ventrain use: laryngeal microsurgery, foreign body in the airway emergency, subglottic stenosis and assistance to guide extubation in Pierre-Robin syndrome. They indicate that laryngospasm, edema or anatomical distortion, combined with over-vigorous jet insufflation can result in air trapping with subsequent barotrauma and hemodynamic instability. They state that Ventrain is the only ventilation device that provides full ventilation for these situations.
