Compare a New Method and Formula as a Guide for the Intubation of a Left-sided Double-lumen Tube

One-lung ventilation (OLV) is required for the most of thoracic surgery to facilitate surgical visualization by collapsing the lung. The double-lumen tube (DLT) is the commonly used device for OLV. The objective of this study was to compare the accuracy of the distances between vocal cords to carina of trachea and formula base on patient's height as a guide for the intubation of a Left-sided Double-lumen tube

About this study

In previous study, investigators found that the distances between vocal cords to carina of trachea was a useful predictive method for the intubation of a Left-sided Double-lumen tube. However in some hospitals preoperative chest CT scans not contain the vocal cords slice. So in this study investigators will compare the accuracy of the distances between the midpoint of the thyroid cartilage to suprasternal notch base on body surface measurement add the distance between suprasternal notch to carina of trachea according to chest CT and formula base on patient's height as a guide for the intubation of a Left-sided Double-lumen tube.

Who can participate

Healthy volunteers accepted: Yes

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Adult patients undergoing elective left side thoracic surgery
  • Requiring a Uniblocker or DLT for one-lung ventilation

Treatment and study plan

Measurement

Other

The distances between the midpoint of the thyroid cartilage to suprasternal notch base on body surface measurement add the distance between suprasternal notch to carina of trachea according to chest CT

Formula

Other

The formula base on patient's height as a guide for the intubation of a Left-sided Double-lumen tube

Primary outcomes

  1. The incidence of the injuries of bronchi and carina

    Time frame: 1-3days

    The degree of bronchi and carina injuries: 1 clear; 2 a few petechiae; 3coalesced petechiae, hemorrhage, or ecchymosis; 4 erosion

Secondary outcomes

  1. The incidence of dislodgement

    Time frame: 1 day

    The incidence of dislodgement after repositioning

  2. The intubation time

    Time frame: 1-5min

    The intubation time (IT) was defined as the time from the anesthesiologist inserted the video laryngoscope between the teeth of patients until the double lumen-tube at the optimal position checked by Fiberoptic bronchoscopy
