An interventional study of Laryngoscope assisted lightwand intubation and Lightwand intubation in Cervical Spine Surgery, sponsored by Seoul National University Hospital. Status unknown at 1 site in Korea, Republic of. Open to participants aged 20 Years to 80 Years. Per ClinicalTrials.gov, last updated 2014-10-24.

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.
Seoul National University Hospital is the lead sponsor of 1,860 studies on the registry; 275 are open to participants now.
Of its 12 completed or terminated interventional studies of FDA-regulated products, 2 (17%) have results posted.

Exclusion Criteria:
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.
Procedure: 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.
Procedure: Laryngoscope assisted lightwand intubation
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.

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.

The success rate of intubation
confirm the success intubation via end tidal CO2 measurement
Time frame: up to 60 seconds
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.
Time frame: from the insertion of the lightwand or laryngoscope into the oral cavity to the point of transillumination over the cricothyroid membrane within 60 sec.
The times of scooping of lightwand
Within 1min after insertion of lightwand into oral cavity, check the scooping time of lightwand during intubation.
Time frame: within 1min after insertion of lightwand
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.
Time frame: at postanesthetic care unit (PACU) within 1hr after end of anesthesia
Incidence of moderate to severe postoperative sorethroat
check the postoperative sorethroat \>3 at PACU in each patient. Numeric rating scale(NRS) was used to measure the severity of pain 0 to 10. 0-3 : mild 4-7 : moderate 8-10 : severe
Time frame: at postanesthetic care unit (PACU) within 1hr after end of anesthesia
other possible postoperative complications
tinged blood to endotracheal tube or in oral cavity. hoarseness
Time frame: just after extubation, an expected average of 1hr
