Airway Management in Surgical Patients With Obstructive Sleep Apnea.

Anesth Analg 2021 05;132(5):1321-1327

Department of Anesthesia, Toronto Western Hospital, University of Toronto, Ontario, Canada.

Obstructive sleep apnea (OSA) is the most common sleep-related breathing disorder, and the difficult airway is perhaps the anesthesiologists' quintessential concern. OSA and the difficult airway share certain similar anatomical, morphological, and physiological features. Individual studies and systematic reviews of retrospective, case-control, and large database studies have shown a likely association between patients with OSA and the difficult airway; OSA patients have a 3- to 4-fold higher risk of difficult intubation, difficult mask ventilation, or a combination of both.

Ventilating the Bearded: A Randomized Crossover Trial Comparing a Novel Bag-Valve-Guedel Adaptor to a Standard Mask.

Mil Med 2020 08;185(7-8):e1300-e1308

Institute for Research in Military Medicine (IRMM) of the Faculty of Medicine, The Hebrew University of Jerusalem, Israel and the Israel Defense Forces Medical Corps, Israel.

Introduction: Emergency field ventilation using bag-valve face mask devices can be difficult to perform, especially in bearded individuals. In view of the increasing numbers of servicemen and civilians sporting a beard or moustache, the issue of finding a technical solution for ventilation in this population has gained importance. We therefore developed a novel adaptor that enables the direct connection of a bag-valve device to a Guedel-type oropharyngeal airway device thereby directly connecting the oral airway to the bag valve, eliminating the need for a face mask.
