The management of unanticipated difficult airway is a clinical challenge to anesthesiologists. The ETView Tracheoscopic Ventilation Tube (ETView), which is capable of real-time video imaging of the airway without needing additional equipment, may provide a promising settlement for the cases. Here, we reported a successful management of unanticipated difficult bag-mask ventilation airway with the ETView. More importantly, we successfully maintained oxygenation by modifying its injection and suction port.
