Rigid Video Stylet Vs Conventional Lightwand Intubation

Not Applicable

• Conditions: Hoarseness; Intubation; Sorethroat
• Interventions: Device: Rigid video stylet; Device: Conventional lightwand intubation

• Registration Number: NCT02073786
• Lead Sponsor: Seoul National University Hospital

Brief Summary

Lightwand is a useful alternative device for intubation but scooping movement can induce damage and microbleeding of oral mucosa, postoperative hoarseness,sore throat. Optiscope is rigid video stylet which has camera on distal tip of device. In many previous studies, rigid video stylet has proven advantages compared with other intubating devices.

Arm && Interventions

Group	Intervention	Description
Optiscope	Rigid video stylet	Rigid video stylet, manufactural named Optiscope, will perform for intubation
Lightwand	Conventional lightwand intubation	Conventional lightwand intubation will performe for intubation

Primary Outcome Measures

Name	Time	Method
Primary success rate of intubation	within 90 sec from insertion of device	compare primary success rate of intubation using Optiscope with lightwand intubation

Secondary Outcome Measures

Name	Time	Method
postoperative complications	24 hr after operation	check the postoperative hoarseness, sorethroat and using numeric rating scale (0-10 point) we checked sorethroat score
number of intubation trial and scooping movements	during intubation time, an expected average of 1minute	Check the number of intubation tiral and scooping movements during intubation
Intubation time	within 90 seconds from insertion of device	Check the intubation time (sec) Intubation time defines "from insertion of device to oral cavity of patients to confirm successful intubation"
hemodynamic change	baseline and 1minute after intubation	check the changes of mean blood pressure, heart rate, pulse oximetry before and after intubation
