Effect of Small Double-lumen Tube on the Intubation Time of Thoracoscopic Pulmonectomy in Asian Women

The purpose of this experiment is to verify whether selecting a double-lumen tube one size smaller based on the traditional personalized method can shorten the intubation time without increasing ventilation complications when performing tracheal intubation for thoracic surgery in Asian women.Patients receive double-lumen tubes of a size selected based on the traditional personalized method or one size smaller than that chosen by the traditional method during tracheal intubation. The primary outcome is the time duration required to complete Double-lumen tube intubation and positioning.
