Comparison of Digital Intubation (Two-finger) and Video Laryngoscopy

In the NGT Digital Intubation group (group B), the second and third fingers were placed in the posterior pharynx and depressed the tongue downwards. The NGT was passed through the nose into the posterior pharynx with the fingers in the pharynx to reach the esophagus. The thumb was placed under the jaw and pushed it forward to pave the way for tube insertion.

In the NGT Video Laryngoscopy group (group A), first, the GlideScope blade was inserted under direct visualization via color monitor through the patient's mouth by employing jaw-thrust maneuver to preserve the cervical spine and by raising the tongue to obtain better visualization of the larynx space. Then, NGT was inserted through the selected nostril, advanced through the esophagus under direct vision to meet the measured length, and fixed after confirmation.
