Not Applicable

Completed

• Conditions: Anesthesia; Intubation Complication; Intubation;Difficult
• Interventions: Device: McGRATH laryngoscopy; Device: Macintosh laryngoscopy

• Registration Number: NCT04509453
• Lead Sponsor: Udayana University

Brief Summary

Various techniques have been developed to get a good LMA position, one of them is using a laryngoscope. The most popular laryngoscope used for LMA installation is the Macintosh type. Technological developments have brought laryngoscopes into the video era, one of which is McGRATH's laryngoscope, which from several studies about having an advantage in terms of the first attempt, time, complications, and hemodynamic stability of intubation. It needs to be proven through research on the comparison of clinical outcomes of LMA installation with McGrath laryngoscope and Macintosh laryngoscope.
