The Rate of Successful Intubation and the Required Time for Intubation, Using Vie Scope and Macintosh Laryngoscope Will be Compared, in Order to Evaluate the Efficacy of Vie Scope in Comparison With Macintosh: Hence, a Randomized Controlled Prospective Single-blind Clinical Trial Will be Conducted

Study Overview
=================
Brief Summary
-----------------
The rate of successful intubation and the required time for intubation, using Vie Scope and Macintosh Laryngoscope will be compared, in order to evaluate the efficacy of Vie Scope in comparison with Macintosh. Hence, a randomized controlled prospective single-blind clinical trial will be conducted. Inclusion criteria: patients of both sexes, positive or negative rapid test for COVID-19 or possible contamination, age ≥18 years old, BMI: 18.5 - 30 kg/m2, visualization of the glottis grade 1 or 2, according to Cormack-Lehane Classification. Exclusion criteria: age under 18 years old, BMI under 18.5 kg/m2 and BMI over 30 kg/m2, visualization of the glottis grade 3 - 4, according to Cormack-Lehane Classification. The laryngoscopy and intubation of the patients will be attempted by the same person-resident of Anesthesiology, under the supervision of experienced Anesthesiologist consultants.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Patients being intubated using Macintosh laryngoscope<br> | Device: Macintosh laryngoscope<br>* Macintosh laryngoscope has been the gold standard for endotracheal intubation since the middle of 20th century. During laryngoscopy and direct vision of the vocal cords, an endotracheal tube is passed into the trachea, establishing the airway.<br>|
| Experimental: Patients being intubated using Vie Scope laryngoscope<br> | Device: Vie Scope<br>* Vie Scope is a laryngoscope, whose function is relied on Seldinger technique. Firstly, bougie is passed through the translucent barrel of Vie Scope under direct vision between the vocal cords and into the trachea. Then, Vie Scope is removed and an endotracheal tube is passed over the bougie, which will be finally removed. The inflation of the endotracheal tube&#39;s cuff is followed by ventilation and confirmation of the tube placement.<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Rate of successful intubation |  | This outcome depends on whether the intubation of each patient will be successful or not, during | 
| Required mean intubation time |  | From insertion of the laryngoscope into the patient's mouth to the inflation of tube's cuff on each patient | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| rate of successful intubation with the first attempt |  | This outcome depends on whether the intubation of each patient will be successful or not, during | 
| Visualization of glottis, according to Cormack Lehane classification |  | This outcome will be evaluated during intubation of each patient |
