Description

This is a very safe and beneficial clinical study. We hope to obtain near-real airway anatomical parameters of patients before surgery through airway three-dimensional reconstruction technology, to assist anesthesiologists in matching the most suitable double-lumen bronchial tube size for each patient, thereby reducing the rate of intubation failure and the occurrence of perioperative adverse events to a certain extent.

Interventions

3D Airway Reconstruction-Guided Double-Lumen Tube Intubation (Procedure)
Patients in this group will undergo preoperative chest CT scanning. The DICOM data will be imported into reconstruction software to create a 3D model of the trachea and bronchi. The diameter of the trachea, left and right main bronchus will be measured on the 3D model to select the appropriate size of the double-lumen tube (DLT). The 3D model can also provide suggestions on the depth of intubation and the bifurcation angle of the bronchus. During anesthesia induction, the selected DLT will be inserted based on the measurements derived from the 3D model.
Gender and Height-Based Double-Lumen Tube Selection (Procedure)
Patients in this group will undergo DLT intubation guided by conventional clinical experience. The DLT size will be selected based on the patient's gender and height according to standard clinical formulas or empirical rules. No preoperative 3D airway reconstruction will be performed for tube sizing.

Eligibility criteria

Inclusion Criteria: * ①Aged 18-75 years, undergoing elective VATS thoracic surgery, with DLT during the procedure; ②ASA physical status I-III; ③ Preoperative chest CT data available for 3D reconstruction; ④ Agree to participate in this study and voluntarily sign the informed consent form. Exclusion Criteria: * ① Preoperative presence of severe respiratory diseases, such as severe chronic obstructive pulmonary disease (COPD), pulmonary infection, and asthma exacerbation; ② Clinically assessed as a difficult airway, such as limited head tilt, spinal deformity, airway or head and neck masses, significant abnormalities in airway anatomy, etc.
