Ideal Point of Transluminal Light in Tracheal Intubation With a Light Wand

If the patients's teeth are weak or the mouth dose not open well, the lightwand is a useful device when endotracheal intubation is necessary.

Therefore, if the appropriate position of the light beam is determined and the distance of the light source suitable for intubation using the lightwand is obtained from anatomical structures such as thyroid cartilage and cricoid cartilage, it is clinically useful. Because it can prevent unnecessary deep insertion or shallow insertion that can cause damage to anatomical structures during intubation.

About this study

Studies have been reported on the proper position to bend the lightwand and the appropriate angle to bend when performing endotracheal intubation with lightwand. For ease of procedure, the assistant has to lift the patient's lower jaw or perform a neck extension.

However, there is no report on the position of the lightbulb when the light passes through the front of the airway and neck and appears bright in the midpoint.

The prodcedure is as follows.

  • FOB examination and check position of light below 1cm from vocal cord
  • lightwand intubation aimed at checkpoint
  • measurement of distance from thyroid cartilage/cricoid cartilage to light point

Who can participate

Healthy volunteers accepted: No

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

Inclusion criteria

  • impossibility of neck extension
  • trismus
  • weak teeth

Exclusion criteria

  • previous history of larynx or neck surgery
  • no informed consent

Treatment and study plan

lightwand intubation

Procedure

intubation using lightwand

Primary outcomes

  1. distance from lightbeam of the FOB to thyroid cartilage

    Time frame: before intubation

    we will measure straight distance from lightbeam of the FOB to thyroid cartilage on the surface of patient's neck

  2. distance from lightbeam of the FOB to cricoid cartilage

    Time frame: before intubation

    we will measure straight distance from lightbeam of the FOB to cricoid cartilage on the surface of patient's neck

Secondary outcomes

  1. distance from lightbeam of the FOB to sternal notch

    Time frame: before intubation

    we will measure straight distance from lightbeam of the FOB to sternal notch on the surface of patient's neck
