Glottic Visualisation During Laryngoscopy

Not Applicable

Completed

• Conditions: Intubation
• Interventions: Device: Mcgrath Mac Videolaryngoscope

• Registration Number: NCT04003727
• Lead Sponsor: Tokat Gaziosmanpasa University

Brief 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.

Detailed 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.

Arm && Interventions

Group	Intervention	Description
Head Extension position	Mcgrath Mac Videolaryngoscope	Head will be on simple extension position
Sniffing Position	Mcgrath Mac Videolaryngoscope	Head and neck will be on sniffing position
Neutral Position	Mcgrath Mac Videolaryngoscope	Head and neck will be on neutral position.

Primary Outcome Measures

Name	Time	Method
Glottic view	During laryngoscopy	the percentage of glottic opening (POGO) and cormack-lehane scores will be used to rate of the glottic view
Intubation Success	During intubation	Intubation attempt number will be recorded

Secondary Outcome Measures

Name	Time	Method
Intubation time	During Intubation	The duration of the endotracheal tube placement will be recorded
Intubation difficulty	During Laryngoscopy	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.
