Conditions

Difficult Intubation, Difficult Mask Ventilation

Brief summary

Videolaryngoscopy provides a better laryngeal view and do not need airway alignment for tracheal intubation.

Detailed description

The C-MAC-VS can be connected easily to the same C- MAC monitor and Pocket Monitor without requiring any additional light source and camera. This device is great for cases with limited mouth opening, airway obstruction and difficult intubation. C-MAC-VS has no lumens so it's very easy to clean and it can accommodates a size ETT 6.0 and greater.

Interventions

DEVICEC-MAC VS

patients undergoing tracheal intubation using the C-MAC VS

DEVICEC-MAC VL D -blade

patients undergoing intubation using the C-MAC VL D-blade.

Masking

DOUBLE (Subject, Investigator)

Intervention model description

The patients will be randomly assigned into two equal groups using computer-generated randomization technique. Group C-MAC VS (VS group) included patients undergoing tracheal intubation using the C-MAC VS. Group C-MAC VL D -blade (D group) included patients undergoing intubation using the C-MAC VL D-blade.
