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

The selection of double-lumen tube sizes using traditional methods relies on two factors: height and gender. In this study, all patients planned to be enrolled are female, so the traditional corresponding relationship is roughly as follows: For patients with a height of less than 152 cm, a 32Fr (French) tube is often selected. For patients with a height between 152 - 165 cm, a 35Fr tube is often selected. For patients with a height between 165 - 177 cm, a 37Fr tube is often selected. For patients with a height of more than 177 cm, a 39Fr tube is often selected.
