AbstractIn obese patients with unfavorable airways, awake fiberoptic intubations are sometimes performed to maintain spontaneous respiration and airway reflexes, until a secure airway is attained. Obese patients may be sensitive to the effects of sedation. Rapid oxygen desaturation may occur as a result of brief moments of apnea from even minimal amounts of sedating medications, due to poor baseline functional reserve as well as common comorbid conditions such as obstructive sleep apnea and obesity hypoventilation syndrome. To maximize the chance of success when performing an awake fiberoptic intubation in a minimally sedated patient, the upper airway should be sufficiently anesthetized. Adequate topical anesthesia minimizes airway stimulation, optimizes patient comfort and facilitates patient compliance. We report two cases of awake fiberoptic intubation in two morbidly obese patients, where a simple apparatus, made of an atomizer embedded in an oral airway, was used to effectively topicalize the airway and achieve excellent intubating condition with minimal sedation.Copyright © 2015 Elsevier Inc.
