Head and Neck Positions for Endotracheal Intubation Using a Videolaryngoscope

Impact of Head and Neck Positions on Endotracheal Intubation Using a McGRATH MAC Video Laryngoscope

In this study, the investigators evaluate the effect of head positions (simple extension vs. sniffing position vs. head elevation) on endotracheal intubation using a videolaryngoscope.

Inclusion Criteria:

• Patients scheduled for general anesthesia

Exclusion Criteria:

• Limited neck extension
• Anatomical anomalies or history of surgery in the upper airway
