Clinical Trial Summary

In this study, we aimed to investigate the effects of head and neck positions on the visualization of glottis and the success of intubation during videolaryngoscopy in obese patients.

Description:

Tree different head and neck positions will compare for glottic visualization and intubation success rates in obese patients (BMI> 30 kg / m2) who required endotracheal intubation for general anesthesia between 18-65 years of age.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Glottic view	the percentage of glottic opening (POGO) and cormack-lehane scores will be used to rate of the glottic view	During laryngoscopy
Primary	Intubation Success	Intubation attempt number will be recorded	During intubation
Secondary	Intubation difficulty	Intubation Difficulty Scale(IDS) score will be recorded.The IDS score is derived from seven variables. N1 represents the number of additional intubation attempts, N2 represents the number of additional operators, N3 is the number of alternative intubation techniques used; N4 represents the laryngoscopic view, N5 represents the lifting force applied during laryngoscopy, N6 represents the necessity to apply external laryngeal pressure to optimize glottic exposure, N7 represents the mobility of vocal cord. The IDS score is the sum of all variables and ranges from zero to infinity. A score of 0 indicates an easy tracheal intubation. Intubation is considered difficult if the score is greater than 5.	During Laryngoscopy
Secondary	Intubation time	The duration of the endotracheal tube placement will be recorded	During Intubation
