Along with the technological advances in medicine, videolaryngoscope is the most commonly preferred technique for intubation of expected difficult airway management such as morbidly obese patients. In this prospective controlled clinical study, the purpose is to compare C-MAC videolaryngoscope and McGrath MAC videolaryngoscope in respect to duration of intubation, haemodynamic response, and complications related intubation of morbidly obese patients undergoing bariatric surgery.
It is very important for anesthesiologists to evaluate and make the airway safe in order to start and continue surgical operations. Endotracheal intubation has many important reasons such as ensuring airway control safely during surgical procedure, increasing the depth of anesthesia, need interventions for surgical or anesthetic complications, reduction of dead space, reduction of respiratory effort and prevention of aspiration risk. Mask ventilation and tracheal intubation in morbidly obese patients can be difficult with the anatomical changes caused by obesity. Reduced functional residual capacity in morbidly obese patients makes it difficult to maintain peripheral oxygen saturation at normal limits. Videolaryngoscope, developed in recent years and beginning to take place in the algorithms, facilitate difficult airway management and hence intubation. The use of videolaryngoscope in patients with difficult intubation such as morbid obesity, has been frequently reported in the literature. McGrath videolaryngoscope has a high-resolution video camera, a length-adjustable angle blade, and a light source at the tip of the blade. At the same time, the C-MAC videolaryngoscope is another advanced videolaryngoscope with a better quality video and camera system and improves the performance of videolaryngoscope with some technological changes. In this prospective controlled clinical study, the purpose is to compare C-MAC videolaryngoscope and McGrath MAC videolaryngoscope in respect to duration of intubation, haemodynamic response, and adverse events associated with intubation of morbidly obese patients undergoing bariatric surgery.

Time to intubation
Time to intubation was defined as the time from when the anesthesiologist picked up the videolaryngoscope to when the anesthesiologist successfully placed the endotracheal tube through the vocal cords
Time frame: From beginning of holding videolaryngoscope to seeing two meaningful end-tidal carbon dioxide levels up to 3 minutes

Heart Rate
Time frame: From beginning of Anesthesia induction to 5th minutes of intubation
Mean Arterial Pressure
Mean Arterial Pressure
Time frame: From beginning of Anesthesia induction to 5th minutes of intubation
Adverse Events
Bleeding in the mouth, edema in the mouth, burst of intubation tube cuff, external laryngeal press, presence of head position change, laryngospasm, hypoxia, hoarseness, throat ache
Time frame: During the first 24 hour postoperatively
