Comparison of Storz C-MAC and D-MAC Orotracheal Intubation Systems in Morbidly Obese Patients

Completed · Phase 4

Conditions studied: Obesity

In brief

The investigators hypothesize that the D-MAC (Dblade with C-MAC system) may be a suitable alternative device for difficult laryngoscopy and tracheal intubation in morbidly obese patients. The D-MAC will enable superior view of the glottic structures as well as easier endotracheal intubations than the C-MAC blade. This is the first study to investigate the individual and comparative performances of C-MAC and D-MAC in this patient cohort.
