A Randomized Controlled Trial of 3D Airway Reconstruction for Precise Double-Lumen Bronchial Intubation

A Randomized Controlled Clinical Study on the Precise Positioning of Double-lumen Bronchial Intubation Guided by Medical Imaging-based Airway Three-dimensional Reconstruction Technology

Sponsor

Peking Union Medical College Hospital

Enrollment

174 participants

Start Date

Aug 14, 2026

Study Type

INTERVENTIONAL

Conditions

Pulmonary Nodules

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.

Eligibility

Plain Language Summary

Simplified for easier understanding

This clinical trial is studying a procedure called 3D Airway Reconstruction-Guided Double-Lumen Tube Intubation and a procedure called Gender and Height-Based Double-Lumen Tube Selection for people with pulmonary nodules. The study is currently recruiting participants at 1 location. People eligible for this study include aged 18 Years to 75 Years.

Interventions

PROCEDURE3D 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.

PROCEDUREGender 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.
