Rigid Video Stylet Vs Conventional Lightwand Intubation

N/AUnknownNCT02073786

Seoul National University Hospital168 enrolled

Overview

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.

Conditions

Hoarseness Intubation Sorethroat

Interventions

Conventional lightwand intubationDEVICE

Conventional lightwand intubation technique will perform during intubation

Rigid video styletDEVICE

Rigid video stylet will inserted through endotracheal tube before induction. After induction with propofol and remifentanil using TIVA infusion pump, rocuronium 0.6mg/kg were used to facilitate intubation. After 2minutes, board-certificated anesthesiologist perform intubation using Optiscope.

Outcomes

Primary Outcomes

Primary success rate of intubation

compare primary success rate of intubation using Optiscope with lightwand intubation

Time frame: within 90 sec from insertion of device

Secondary Outcomes

Intubation time

Check the intubation time (sec) Intubation time defines "from insertion of device to oral cavity of patients to confirm successful intubation"

Time frame: within 90 seconds from insertion of device

postoperative complications

check the postoperative hoarseness, sorethroat and using numeric rating scale (0-10 point) we checked sorethroat score

Time frame: During PACU stay time expected up to 1hr

postoperative complications

check the postoperative hoarseness, sorethroat and using numeric rating scale (0-10 point) we checked sorethroat score

Time frame: 24 hr after operation

hemodynamic change

check the changes of mean blood pressure, heart rate, pulse oximetry before and after intubation

Time frame: baseline and 1minute after intubation

number of intubation trial and scooping movements

Check the number of intubation tiral and scooping movements during intubation

Time frame: during intubation time, an expected average of 1minute
