Comparison of Two Different Lightwand Intubation Techniques in Cervical Immobilized Patients

Comparison of the Intubation Success Rate Between Two Techniques Using Lightwand in Patients Undergoing Spine Surgery: Conventional vs. Face-to-face Technique

This study compares two different approaches of lightwand intubation techniques in cervical immobilized patients.

This study compares two approaches in lightwand intubation techniques in cervical immobilized patients. One is a conventional approach that involves scooping movement with mandible protraction. The other is a face-to-face approach that inserts lightwand with a front-facing position. This study is conducted as a randomized, prospective, single-blinded design.
