Summary

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.

Conditions

  • Morbid Obesity
