Adequate Bending Angle of a Lightwand

Not Applicable

Completed

• Conditions: Tracheal Intubation
• Interventions: Procedure: bending angle of a lightwand

• Registration Number: NCT03693235
• Lead Sponsor: Seoul National University Hospital

Brief Summary

For tracheal intubation with a lightwand, adequate bending angle was not exactly investigated. The purpose of the study is compare three bending angles of lightwands for safe and efficient tracheal intubation.

Detailed Description

Lightwands are very useful device for difficult airway management due to small moth opening, weak teeth, and cervical spine instability. Experienced clinicians use a lightwand while bending it adequately. However, there has been not previous studies to investigate the adequate angle to bend it.

This randomized controlled trial is to compare three angles (70, 80, and 90 degrees) as bending angle of lightwands for safe and efficient tracheal intubation in cases which require the use of lightwands.

Arm && Interventions

Group	Intervention	Description
70 degrees	bending angle of a lightwand	During tracheal intubation using a lightwand, the tracheal tube combined with a lightwand will be bent by 70 degrees.
80 degrees	bending angle of a lightwand	During tracheal intubation using a lightwand, the tracheal tube combined with a lightwand will be bent by 80 degrees.
90 degrees	bending angle of a lightwand	During tracheal intubation using a lightwand, the tracheal tube combined with a lightwand will be bent by 90 degrees.

Primary Outcome Measures

Name	Time	Method
sore throat	After surgery	After surgery, investigators evaluate VAS score for sore throat of the patients.
Intubation time	Intraoperative	from initiation of tracheal intubation with a lightwand after bending it to completion of tracheal intubation
