McGrath vs. C-MAC Video Laryngoscopy Comparison in Endotracheal Tube Insertion

Tracheal intubation is commonly performed using a standard Macintosh blade, but recently there has been advanced technology using video laryngoscopy (VL).In this modern era, there are various types of available VL to make it easier for anesthesiologists to perform intubation, especially in patients with difficult airway anatomy.

Various studies showed different results regarding the effectiveness of both C-MAC® and McGrath®, by assessing the comparison of the effectiveness, valuable information will be obtained for further consideration by experts in choosing the best tools in the future.

Device

Endotracheal intubation using either McGrath or C-MAC video laryngoscopy

Primary outcomes

  1. Intubation time

    Time frame: From first intubation attempt until successful intubation, an average of one minute

    Time required to perform intubation until endotracheal tube is properly positioned

  2. Ease of intubation

    Time frame: From first intubation attempt until successful intubation, an average of two minutes

    Difficulty level of intubation, scores 1-2, 1=effortless, 2=difficult

Secondary outcomes

    The number of times required for a successful intubation

  2. Glottic visualization

    Time frame: During first intubation attempt, an average of 30 seconds

    Visualization of glottic assessed by the POGO (Percentage of Glottis Opening) score, 1=best, 4=worst

  3. Complications of intubation

    Time frame: From first intubation attempt until successful intubation, an average of one minute

    Includes orotracheal trauma, presence of blood in the blades, laryngospasm, bradycardia
