Randomized Controlled Trial
Utility of oxygen insufflation through working channel during fiberoptic intubation in apneic patients: a prospective randomized controlled study.
Airway management is a part of routine anesthetic procedures; however, serious complications, including hypoxia and death, are known to occur in cases of difficult airways. Therefore, alternative techniques such as fiberoptic bronchoscope-assisted intubation (FOB intubation) should be considered, although this method requires more time and offers a limited visual field than does intubation with a direct laryngoscope. Oxygen insufflation through the working channel during FOB intubation could minimize the risk of desaturation and improve the visual field. Therefore, the aim of this prospective randomized controlled study was to evaluate the utility and safety of oxygen insufflation through the working channel during FOB intubation in apneic patients. ⋯ These findings suggest that oxygen insufflation through the working channel during FOB intubation aids in extending the apneic window during the procedure.

Observational Study
Effects of the anesthesiologist's experience on postoperative hoarseness after double-lumen endotracheal tube intubation: a single-center propensity score-matched analysis.
Postoperative hoarseness after general anesthesia is associated with patient discomfort and dissatisfaction. A recent large retrospective study showed that single-lumen endotracheal tube intubation by a trainee did not alter the incidence of postoperative pharyngeal symptoms compared with intubation by a senior anesthesiologist. However, there is limited information about the relationship between the anesthesiologist's experience and hoarseness after double-lumen endotracheal tube intubation. We tested the hypothesis that double-lumen endotracheal tube intubation performed by a trainee increases the incidence of postoperative hoarseness compared to intubation by a senior anesthesiologist. ⋯ Double-lumen endotracheal tube intubation by trainee anesthesiologists with < 2 years of experience increased the incidence of postoperative hoarseness 24 h after surgery compared to intubation by senior anesthesiologists with ≥2 years of experience.

Case ReportsThe Difficult Airway and Aerosol-Generating Procedures in COVID-19: Timeless Principles for Uncertain Times.
The impact of the COVID-19 pandemic on otolaryngology practice is nowhere more evident than in acute airway management. Considerations of preventing SARS-CoV-2 transmission, conserving personal protective equipment, and prioritizing care delivery based on acuity have dictated clinical decision making in the acute phase of the pandemic. With transition to a more chronic state of pandemic, heightened vigilance is necessary to recognize how deferral of care in patients with tenuous airways and COVID-19 infection may lead to acute airway compromise. ⋯ Teams should consider trade-offs among aerosol-generating procedures involving direct laryngoscopy, supraglottic airway use, fiberoptic intubation, and tracheostomy. We share clinical cases that illustrate enduring principles of acute airway management. As algorithms evolve, time-honored approaches for diagnosis and management of acute airway pathology remain essential in ensuring patient safety.
