Abstract Background Excessive dynamic airway collapse (EDAC) is an uncommon cause of high airway pressure during mechanical ventilation. However, EDAC is not widely recognized by anesthesiologists, and therefore, it is often misdiagnosed as asthma. Case presentation A 70-year-old woman with a history of asthma received anesthesia with sevoflurane for a laparotomic cholecystectomy. Under general anesthesia, she developed wheezing, high inspiratory pressure, and a shark-fin waveform on capnography, which was interpreted as an asthma attack. However, treatment with a bronchodilator was ineffective. Bronchoscopy revealed the collapse of the trachea and main bronchi upon expiration. We reviewed the preoperative computed tomography scan and saw bulging of the posterior membrane into the airway lumen, leading to a diagnosis of EDAC. Conclusions Although both EDAC and bronchospasm present as similar symptoms, the treatments are different. Bronchoscopy proved useful for distinguishing between these two entities. Positive end-expiratory pressure should be applied and bronchodilators avoided in EDAC.

Abstract The term ‘tracheostomy’ or ‘tracheotomy’ refers to the procedure whereby a communication is made between the anterior wall of the trachea and the exterior which bypasses the upper air passages. It results in the formation of a fistulous tract between the anterior aspect of the neck and the trachea allowing air to enter the lower respiratory passages without passing through the nose, pharynx and larynx. It is performed at all ages, however, there are significant differences in the procedure when performed in adults and children. ‘Laryngotomy’ or ‘cricothyrotomy’ is the emergency operation where the airway is opened through the cricothyroid membrane in case of acute respiratory obstruction where there is no time for tracheostomy or inavailability of a competent surgeon to perform the tracheostomy. It is a relatively simple procedure and life-saving.
