NCT05899270

Brief Summary

Lung isolation techniques are commonly used to facilitate surgical exposure and to provide single-lung ventilation for patients. We have developed an automatic comparison software for 3D reconstruction based on CT data (3DRACS). It reconstructs the trachea and bronchus and compares them with the DLT, predicting the most suitable size and depth of the DLT for lung isolation.The aim of this study was to compare whether the use of 3DRACS to select a DLT size compared to conventional empirical selection methods could improve incidence of DLT intubation success and reduce airway injury.

Outcome Measures

Primary Outcomes (1)

  • Incidence of correct endobronchial intubation.

    Conventional blindly endobronchial intubation is performed firstly and clinical verification was made by the same anesthesiologist, followed by the supervising anesthesiologist using a FOB to check DLT position and successful intubation was considered if the position was proper.

    after intubation

Secondary Outcomes (6)

  • Time to successful intubation

    after intubation

  • Degree of pulmonary atrophy

    after surgery begin

  • Grading of airway injury

    When extubation

  • Postoperative sore throat and hoarseness

    At 1 hour and 24 hours after extubation

  • Oxygenation during one-lung ventilation

    Intraoperative(from beginning of one lung ventilation to end),an average of 2 hours

  • +1 more secondary outcomes

Study Arms (2)

3D group

EXPERIMENTAL

In 3D group, the investigator will intubate using DLT chosen by an automatic comparison software for 3D reconstruction based on CT data (3DRACS).

Other: 3D reconstruction automatic matching system

control group

PLACEBO COMPARATOR

In control group, the size of DLT is based on patient's sex and weight and the height is used to guide the depth of DLT insertion.

Other: traditional method for selecting double lumen tube
