Summary

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.

Conditions

  • Pulmonary Nodules

Interventions

PROCEDURE

3D Airway Reconstruction-Guided Double-Lumen Tube Intubation

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.

PROCEDURE

Gender and Height-Based Double-Lumen Tube Selection

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.
