Abstract
RATIONALE
Some laryngeal masses are typically asymptomatic and easily ignored. However, they can be rare causes of unanticipated difficult airway, leading to critical situations such as "cannot ventilate" or "cannot ventilate and cannot intubate" during anesthesia induction. Inappropriate airway management in such scenarios can have catastrophic consequences for an anesthetized patient. Here we report a case of sudden, unanticipated difficult mask ventilation caused by an asymptomatic supraglottic mass during sedative induction, which was quickly and effectively relieved by the Heimlich maneuver and chest compression.
PATIENT CONCERNS
We report a rare case of airway crisis occurred during sedative induction in a 63-year-old patient scheduled for a routine flexible bronchoscopy, and no evidence of respiratory difficulty or signs of obstruction was found in preoperative evaluation.
DIAGNOSES
A detailed examination of laryngopharyngeal structure under bronchoscopy revealed a supraglottic soft-tissue mass with a size of 1.6 × 0.8 cm covering the membranous part of the glottic area, which was the true cause of difficult mask ventilation in this patient during sedative induction.
INTERVENTIONS
As the unanticipated difficult mask ventilation occurred, 2-handed mask ventilation was initiated immediately for 9 attempts but failed. Fortunately, the airway crisis was successfully relieved with 2 Heimlich attempts and 3 chest compressions, and no need for a laryngeal mask airway.
OUTCOMES
Once the airway crisis was relieved and the supraglottic mass was confirmed, the patient underwent a second sedative anesthesia and a successful laryngeal mask airway-assisted bronchoscopy, with no post-bronchoscopy adverse events.
LESSONS
Asymptomatic supraglottic masses can cause valve-like upper airway obstruction and lead to unanticipated difficult mask ventilation. The Heimlich maneuver and chest compression may be effective in such critical situations and can serve as an emergency intervention.
