Videolaryngoscope Blades for Nasal Intubation
(ASING Trial)
What You Need to Know Before You Apply
What is the purpose of this trial?
This study compares two videolaryngoscope blade designs for nasal tracheal intubation in patients undergoing surgery under general anesthesia. Participants will be randomly assigned to undergo nasal tracheal intubation using either a hyperangulated C-MAC® D-BLADE® or a Macintosh-style videolaryngoscope blade.
The study will evaluate the effectiveness of each approach by measuring time to successful intubation, number of intubation attempts, airway maneuvers required, and other procedural outcomes. Safety outcomes, including airway- and anesthesia-related adverse events, will also be assessed. The findings may help identify the most effective and safe videolaryngoscope blade design for nasal tracheal intubation.
Are You a Good Fit for This Trial?
This trial is for adults who need nasal intubation while having surgery under general anesthesia. People with conditions that make nasal intubation unsafe or difficult, or those with certain airway problems, may not be eligible.Inclusion Criteria

What Are the Treatments Tested in This Trial?
Trial Overview
The study compares two types of videolaryngoscope blades—the hyperangulated D-BLADE and the standard Macintosh blade—for helping doctors place a breathing tube through the nose during surgery. Participants are randomly assigned to one of the two groups.

Experimental Treatment
Participants randomized to this arm will undergo nasal tracheal intubation using a C-MAC® Videolaryngoscope with a Macintosh-style blade (size 3 or size 4, as clinically appropriate). The assigned device will be used for the initial study intubation attempt following induction of general anesthesia. Intubation will be performed according to the study protocol, with procedural outcomes including time to successful intubation, number of attempts, and airway maneuvers recorded.
