Intubation in Supine Versus Lateral Position Using Different Tools of Laryngoscopy in Patients With Neck Masses

Endotracheal Intubation in Supine Versus Lateral Position Using Different Tools of Laryngoscopy in Patients With Neck Masses: A Comparative Study

This study is aimed to compare different tools of endotracheal intubation in supine versus lateral position in patients with neck masses.

Primary outcome: is time taken for intubation.

Secondary outcomes:

• The success rate of first intubation trial.
• Hypoxia, Spo2 < 90%.
• Airway trauma like; dental and lip injury.

Study Plan

How is the study designed?

Number of groups / cohorts

4

Cohorts and Interventions

Group / Cohort
Group-SM; patients will be intubated in supine position in whom the Macintosh laryngoscope will be used
Group-SV; patients will be intubated in supine position in whom the video-assisted laryngoscopy will be used
Group-LM; patients will be intubated in lateral position in whom the Macintosh laryngoscope will be used
Group-LV; patients will be intubated in lateral position in whom the video-assisted laryngoscopy will be used

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
time taken for intubation	the time for the laryngoscope to pass level of incisors till confirmation of tracheal intubation by capnography	periprocedural (less than 60 seconds)

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
- The success rate of first intubation trial.	Number of intubation attempts (an intubation attempt will be deemed failed if desaturation occurs Spo2 <90 % or intubation failed in <60 seconds). Intubations will be deemed failures after 3 intubation attempts.	through study completion (about 8 months)
