Interaction Between Head/Neck Position and C-MAC Blade Geometry on Videolaryngoscopic Intubation in Morbidly Obese Patients: A Randomized Controlled Trial
Source: ClinicalTrials.gov · Last updated 9 Jun 2026
Brief summary (registry, in English)
This study aims to explore the effect of head/neck position (sniffing vs ramped) and C-MAC blade geometry (MAC vs D-blade) on intubation in morbidly obese patients. The patients will be randomized into 4 groups: 1. S MAC: Sniffing + MAC blade. 2. R MAC: Ramped + MAC blade. 3. S D-blade: Sniffing + D-blade. 4. R D-blade: Ramped + D-blade.
