Boussignac Valve and Fibroptic Intubation in Morbidly Obese Patients, Can it be a Solution?

In this study, fiberoptic intubation through Boussignac valve, while ventilation of morbidly obese patients is maintained through the ventilator, will be studied. Researchers suggest that the technique will allow more time for intubation trial rather than conventional techniques of intubation without ventilation. the Primary outcome will be the decrease of desaturation events during intubation. Secondary variables will include; stress response to intubation, the incidence of hypercapnia, hemodynamic response to intubation, successful intubation, the time required to intubation and operator satisfaction.
