Laryngoscope Asssited Lightwand Intubation

Not Applicable

• Conditions: Cervical Spine Surgery
• Interventions: Procedure: Laryngoscope assisted lightwand intubation; Procedure: Lightwand intubation

• Registration Number: NCT01950702
• Lead Sponsor: Seoul National University Hospital

Brief Summary

To evaluate the success rate for intubation of laryngocope assisted lightwand intubation.

Detailed Description

Light wand intubation is well known for safety intubation in cervical injury patiets. Traditional method of using light wand can damage the supraglottic cavity by scooping the apparatus. The investigators try to evaluate the efficacy of laryngoscope assisted light wand intubation compared to traditional method of using light wand alone.

Arm && Interventions

Group	Intervention	Description
Laryngoscope assisted lightwand intubation	Laryngoscope assisted lightwand intubation	After standard total intravenous anesthesia using propofol and remifentanil continuous infusion, lightwand intubation using specific device(Macintosh laryngosope, female:3/Male:4) was done by pre-specified anesthesiologist who experienced more than 100 times of laryngoscope assisted lightwand intubation.
Lightwand intubation	Lightwand intubation	After standard total intravenous anesthesia using propofol and remifentanil continuous infusion, traditional lightwand intubation was done by pre-specified anesthesiologist who experienced more than 100 times of lightwand intubation. Patient's head were fixed at neutral position during all intubation period.

Primary Outcome Measures

Name	Time	Method
The success rate of intubation	up to 60 seconds	confirm the success intubation via end tidal CO2 measurement

Secondary Outcome Measures

Name	Time	Method
The times of scooping of lightwand	within 1min after insertion of lightwand	Within 1min after insertion of lightwand into oral cavity, check the scooping time of lightwand during intubation.
lightwand search (=intubation) time	from the insertion of the lightwand or laryngoscope into the oral cavity to the point of transillumination over the cricothyroid membrane within 60 sec.	Check the time(sec) from insertion of the lightwand or laryngoscopy into the oral cavity to push the endotracheal tube into the trachea.
