Abstract <p>Obesity is a global health challenge. An increasing number of patients with obesity are admitted to an intensive care unit. Airway management in these patients represents a unique challenge due to significant anatomical and physiological alterations. Increased adipose tissue in the face, cheeks, pharynx, hypopharynx, and neck narrows the upper airway, renders soft tissues more collapsible, and complicates airway management. In addition, the functional residual capacity is reduced, resulting in markedly shortened safe apnea time, contributing to severe hypoxemia during intubation. Non-invasive ventilation is effective in mitigating this risk and should be applied from pre-induction to laryngoscopy. Peri-intubation physiological optimization should include assessment of preload and cardiac contractility, with careful consideration of right ventricular strain. The transition from negative to positive intrathoracic pressure should be closely monitored, with cautious titration of positive end-expiratory pressure. Recognition of these anatomical and physiological challenges may prompt clinicians to consider awake intubation in selected patients. When rapid sequence induction is performed, both ketamine and etomidate are appropriate options; the choice between them should be guided by the clinical context, patient characteristics, local practice patterns and availability. Videolaryngoscopy increases the incidence of successful intubation on the first attempt and should be adopted routinely in the population with obesity. Several questions remain unanswered, including the safety and efficacy of pre-emptive vasopressor use to prevent post-intubation cardiovascular collapse and the optimal dosing of hypnotic agents to achieve ideal intubation conditions, while minimizing adverse events.</p> Visual abstract <p></p>
