Laryngoscope Asssited Lightwand Intubation

Laryngoscope Assisted Lightwand Can Provide More Successful Intubation Than Lightwand Alone in Patients With Cervical Spine Injury : A Prospective Randomized Study

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.
