McGrath Videolaryngoscopy for Nasotracheal Intubation

A Comparison of McGrath Videolaryngoscopy and Macintosh Laryngoscopy for Routine Nasotracheal Intubation

McGrath videolaryngoscopy avoids the use of Magill forceps for nasotracheal intubation, thereby reducing intubation time and complications, especially in patients with a difficult airway. This study was performed to investigate whether McGrath videolaryngoscopy is superior to Macintosh laryngoscopy for routine nasotracheal intubation in expected normal airways, as judged by the time to intubation and ease of intubation.

Inclusion Criteria:

• patients for dental or maxillofacial surgery requiring nasotracheal intubation

Exclusion Criteria:

• known difficult airway
• required rapid sequence induction
• history of bleeding
• cervical spine injury
