Multivariate Analysis of the Failure Risk of First Tracheal Intubation Attempt in a Population of Patients Scheduled for Bariatric Surgery.

Background: Airway management during the administration of anesthesia to patients undergoing bariatric surgery is challenging. The goal is to avoid multiple intubation attempts because the risk of complications increases with the number of attempts. The objective of this study was to determine the failed first intubation attempt rate, as well as variables associated with this failure, in patients undergoing bariatric surgery.
