Clinical Application of Right Visual Double Lumen Tube in Thoracoscopic Surgery for Adult Patients

January 14, 2026 updated by: Diansan Su

Comparison of Clinical Application of Right Visual Double Lumen Tube and Right Ordinary Double Lumen Tube in Thoracoscopic Surgery for Adult Patients

This clinical trial aims to understand whether a visual double-lumen intubation tube can improve the first-attempt success rate and reduce complications compared to a standard double-lumen tube. The trial primarily aims to answer the following questions:

Does a double-lumen tube improve the first-attempt success rate?

Does a visual double-lumen tube reduce the likelihood of obstruction of the right upper lobe bronchial opening?

Does a visual double-lumen tube require fewer adjustments during surgery?

Do patients with visual double-lumen tubes experience fewer perioperative complications compared to those with standard double-lumen tubes?

Participants will:

Use a visual double-lumen tube partially and a standard double-lumen tube partially.

Record the perioperative status of all patients.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Active Comparator: visual double-lumen tube group
Lung-isolation thoracoscopic surgery using a right-side visual double-lumen tube.
Device: visible double-lumen tube
A visible double-lumen tube on the right side
Other Names:
  • visible double-lumen tube group
Active Comparator: Non-visual dual-lumen tube (ordinary dual-lumen tube) group
Lung isolation thoracoscopic surgery was performed with fiberoptic bronchoscopy assistance using a standard double-lumen tube on the right side (non-visual double-lumen tube).
Device: lumen intubation tube
The standard double-lumen tube on the right side was positioned with the aid of a fiberoptic bronchoscope.
Other Names:
  • lumen intubation tube group

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Primary purpose
Time Frame: After anesthesia induction, the laryngoscope is inserted and the timing begins until the endotracheal tube position is confirmed. The endotracheal tube is then fixed, and mechanical ventilation is initiated (approximately 10 minutes).
To study whether the right visual double lumen tube can improve the success rate of initial intubation compared with the right ordinary double lumen tube.
After anesthesia induction, the laryngoscope is inserted and the timing begins until the endotracheal tube position is confirmed. The endotracheal tube is then fixed, and mechanical ventilation is initiated (approximately 10 minutes).

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Secondary purposes
Time Frame: After the endotracheal tube is secured, the patient is ventilated by a ventilator, and ventilation of the right single lung is initiated (lasting approximately 2-3 minutes).
Compare the obstruction of the right upper bronchial opening in the two groups of patients.
After the endotracheal tube is secured, the patient is ventilated by a ventilator, and ventilation of the right single lung is initiated (lasting approximately 2-3 minutes).
Intraoperative cannulation position adjustment
Time Frame: The entire surgery (approximately 1-3 hours).
Compare the number of times the endotracheal intubation position needed to be adjusted and the total adjustment time between the two groups of patients.
The entire surgery (approximately 1-3 hours).
postoperative complications
Time Frame: From the end of surgery to the patient's discharge (2-3 days).
The postoperative complications of the two groups of patients were compared.
From the end of surgery to the patient's discharge (2-3 days).
