Overview

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.

Eligibility

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.
