Study Overview
Brief Summary
This clinical study is designed to compare two different techniques used for inserting a breathing tube (a process known as intubation) in adult patients undergoing thyroid surgery who are predicted to have a difficult airway. A difficult airway refers to a situation where it may be challenging to place the breathing tube due to specific anatomical or physical factors such as restricted neck movement, enlarged thyroid gland (goiter), reduced mouth opening, short neck, or increased soft tissue around the neck. The two techniques being assessed are conventional direct laryngoscopy, which is the traditional method requiring neck extension for a direct view of the windpipe, and video laryngoscopy, a modern approach that uses a camera to visualize the vocal cords on a screen with less need for neck manipulation.
In this randomized controlled trial, a total of 60 patients meeting the eligibility criteria will be included and randomly assigned into two equal groups. One group will undergo intubation using the conventional laryngoscope, while the other group will be intubated using the video laryngoscope. The primary aim of this research is to evaluate which method provides a higher success rate of placing the endotracheal tube correctly on the first attempt. Additional outcomes that will be assessed include the total time taken for intubation, whether the intubation was ultimately successful regardless of the number of attempts, and the occurrence of any immediate injuries within the mouth or throat area during or after the procedure.
The underlying hypothesis of the study is that video laryngoscopy will result in a significantly higher first-attempt intubation success rate as compared to conventional laryngoscopy in patients with predicted difficult airways. This study intends to provide clinically useful evidence to guide anesthesiologists in selecting the most effective and safe intubation technique for patients undergoing thyroid surgery, with the goal of minimizing complications and improving procedural outcomes.

Arms & Interventions
Group A - Conventional Laryngoscopy
Received endotracheal intubation using conventional direct laryngoscope with a Macintosh blade, performed under general anesthesia in patients undergoing thyroid surgery.
Intervention: Conventional Direct Laryngoscope (Device)
Group B - Video Laryngoscopy
Received endotracheal intubation using video laryngoscope under general anesthesia in patients undergoing thyroid surgery.
Intervention: Video Laryngoscope (Device)
Outcomes
Primary Outcomes
First-Attempt Intubation Success Rate
Time Frame: During intubation at the time of induction of anesthesia (Day 0, intraoperative)
Successful placement of the endotracheal tube through the vocal cords into the trachea on the first attempt, confirmed by bilateral chest auscultation and capnography.
Secondary Outcomes
- Overall Intubation Success Rate(During intubation at the time of induction of anesthesia (Day 0, intraoperative))
- Intubation Time(During intubation at the time of induction of anesthesia (Day 0, intraoperative))
- Incidence of Immediate Oropharyngeal Injuries(Immediately post-intubation (within 5 minutes of tube placement, intraoperative))
