No results posted yet for this study

Summary

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.

Interventions

DEVICE

Selecting the size of a Left Double-lumen endobronchialtube one size smaller than the traditional method

During tracheal intubation，choose a Left Double-lumen Endobronchial Tubethat is one size smaller than the traditional method.In this study, all patients planned to be enrolled are female. In experimental group the relationship between height and size is roughly as follows: For patients with a height between 152 - 165 cm, a 32Fr (French) tube is often selected. For patients with a height between 165 - 177 cm, a 35Fr tube is often selected. For patients with a height of more than 177 cm, a 37Fr tube is often selected.

DEVICE

Selecting the size of a Left Double-lumen endobronchialtube according to traditional methods

During tracheal intubation，choose the regular Left Double-lumen endobronchial tube according to the traditional method. 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.
