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

Not Applicable

Completed

• Conditions: Intubation; Difficult or Failed
• Interventions: Device: Endotracheal intubation

• Registration Number: NCT04936516
• Lead Sponsor: Udayana University

Brief Summary

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.
