About

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

Full description

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.

Lightwand intubation

Active Comparator group

Description:

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.

Treatment:

Procedure: Lightwand intubation

Laryngoscope assisted lightwand intubation

Experimental group

Description:

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.
