Brief summary: Endotracheal intubation is usually required to allow unrestricted surgical approach. The Macintosh laryngoscope is the standard method. However in certain situations as difficult airway this technique is ineffective and poorly tolerated by the patient. Fiberoptic intubation is the gold standard in this scenario, however sometimes it is not possible due to failure or unavailability, so alternatives are needed. The TotalTrack (MedComflow SA, Barcelona, Spain) has been designed specifically for the airway management. However, despite its use in clinical practice, there are no comparative studies regarding direct laryngoscopy


Eligibility criteria: Inclusion Criteria:

* Patients undergoing elective general anesthesia requiring OTI.
* Patients duly informed and they have signed the informed consent during the pre-anesthetic consultation, or be sought after due meditation, expressing its consent to the inclusion in the study.

* Not presenting respiratory disease, coronary or cerebral vascular.
* Do not have a sore throat preoperative

Exclusion Criteria:

* Failure to meet the above criteria
* Pregnancy
* Allergy to any drug included in the protocol.
