Hoarseness, Intubation, Sorethroat
Conditions
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.
Interventions
DEVICEConventional lightwand intubation
Conventional lightwand intubation technique will perform during intubation
DEVICERigid video stylet
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.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Primary success rate of intubation | within 90 sec from insertion of device | compare primary success rate of intubation using Optiscope with lightwand intubation |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| 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 |
| postoperative complications | During PACU stay time expected up to 1hr | check the postoperative hoarseness, sorethroat and using numeric rating scale (0-10 point) we checked sorethroat score |
| hemodynamic change | baseline and 1minute after intubation | check the changes of mean blood pressure, heart rate, pulse oximetry before and after intubation |
| 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 |
