 Additionally, there are increased difficulties and risks for tracheal intubation in obese patients versus normal-weight patients. Studies have found that chances for a successful first attempt at oral intubation decrease as patient weight increases.6,7 Improving visualization of laryngeal structures will increase the likelihood of successful tracheal intubation, as increasing the percentage of glottic opening is correlated with the number of intubation attempts, as well as the need for rescue intubation devices.8
