Interaction Between Head/Neck Position and C-MAC Blade Geometry on Videolaryngoscopic Intubation in Morbidly Obese Patients: A Randomized Controlled Trial
Conditions: Morbid Obesity
Sex: All
Ages: 18 Years – 70 Years
Healthy volunteers: No
Phase: NA
Enrollment: 140
Sponsor: Ain Shams University
Location: Ain Shams University Cairo Egypt
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.
Eligibility Criteria
Inclusion Criteria:
* Age 18-70 years.
* BMI ≥ 40 kg/m².
* ASA physical status III - IV.
* Elective surgery requiring intubation.
* Informed consent obtained.
Exclusion Criteria:
* Anticipated difficult airway unrelated to obesity.
* Cervical spine pathology.
* Pregnancy.
* Emergency surgery.
* High aspiration risk.
* OSA requiring CPAP \>15 cmH₂O.
* Need for awake intubation.
