Comparison of Two Different Lightwand Intubation Techniques in Cervical Immobilized Patients

Study Overview
=================
Brief Summary
-----------------
This study compares two different approaches of lightwand intubation techniques in cervical immobilized patients.

Detailed Description
-----------------
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.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Other: Group Conventional<br>Conventional approach using group in lightwand intubation | Procedure: Conventional approach<br>* Patients were positioned supine and the intubator stood above the patient's head. Opening the mouth and slightly pulling the mandible with one hand, the intubator inserted the lightwand-tracheal tube assembly at midline into the patient's mouth under the ambient light being turned off. To identify the location of the lighted tip, the intubator could move the lightwand back and forth gently, Once the red light of the tip was located at the midline of the patient's neck, the pre-launched tube was inserted smoothly into the patient's airway unless there was no resistance<br>|
| Other: Group Face-to-Face<br>Face-to-face approach using group in lightwand intubation | Procedure: Face-to-face approach<br>* A front-facing approach and insert the lightwand following the patient's tongue base curvature without scooping movement<br>|
