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

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Lightwand intubation | Active Comparator | 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. |
|
| Laryngoscope assisted lightwand intubation | Experimental | 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. |

| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| Laryngoscope assisted lightwand intubation | Procedure | After standard monitoring(EKG, pulse oximetry, NIBP), participants were induced with remifentanil and propofol continuous infusion, using targe-controlled infusion device with prexoygenation with 100% oxygen. Manual in-line stabilization was applied with velcro during intubation to maintain neutral head position. The Macintosh laryngoscope (female: 3rd blade, male: 4th blade) was inserted into the oral cavity to provide direct view of the epiglottis and then the tip of the lightwand was placed below the epiglottis. |
| Measure | Description | Time Frame |
|---|---|---|
| The success rate of intubation | confirm the success intubation via end tidal CO2 measurement | up to 60 seconds |
| Measure | Description | Time Frame |
|---|---|---|
| lightwand search (=intubation) time | Check the time(sec) from insertion of the lightwand or laryngoscopy into the oral cavity to push the endotracheal tube into the trachea. | from the insertion of the lightwand or laryngoscope into the oral cavity to the point of transillumination over the cricothyroid membrane within 60 sec. |
| Measure | Description | Time Frame |
|---|---|---|
| score of postoperative sorethroat | check the postoperative sorethroat at PACU in each patient. Numeric rating scale(NRS) was used to measure the severity of pain 0 to 10. | at postanesthetic care unit (PACU) within 1hr after end of anesthesia |
| Incidence of moderate to severe postoperative sorethroat |

| Lightwand intubation | Procedure | After standard monitoring(EKG, pulse oximetry, NIBP), participants were induced with remifentanil and propofol continuous infusion, using targe-controlled infusion device with prexoygenation with 100% oxygen. Manual in-line stabilization was applied with velcro during intubation to maintain neutral head position. After 2min from administration of rocuronium, the clinician holds the wand similar to a pencil, stands directly behind the patient's head, inserts the device into the side of the mouth and sweeps the tip to the midline. After confirmation of precise location via clear light source on anterior neck, endotracheal tube was inserted and withdrawn lightwand. |
