What this study is about

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.

A promising-looking record is not the same as confirmed eligibility. The study team must review the full criteria and current recruitment status.
