McGrath Series 5 Videolaryngoscope for Double-lumen Tube Intubation

1. Double-lumen tube intubation is difficult, compared with single lume tube. 2. McGrath Series 5 videolaryngoscope hase been used in difficult airway management, both in anesthetized and awake patients. 3. But there was little information about McGrath Series 5 videolaryngoscope for double-lumen tube intubation.

Treatment and study plan

Videolaryngoscope

Device

McGrath Series 5 videolaryngoscope is one kind of portable videolaryngoscopes, which has been usde in both unexpected and anticipated difficult intubation.

Primary outcomes

  1. intubation time

    Time frame: at intubation

    defined as time from inserting blade to mouth to three cycles on capnograph

Secondary outcomes

  1. number of successful intubation at first attempt

    Time frame: at intubation

Other outcomes

  1. BMI

    Time frame: one day before operation

  2. mouth opening

    Time frame: one day before operation

    measure with a ruler

  3. Thyromental distance
