Brief Summary:
The use of videolarygoscopy (VL) as first choice for tracheal intubation versus direct laryngoscopy (DL) is a matter of debate. These two methods were compared in several studies. Videolaryngoscopes may reduce the number of failed intubations, particularly among patients presenting with a difficult airway. They improve the glottic view and may reduce airway trauma. DM is accepted as a risk factor for difficult intubation. The aim of this study is to compare VL to DL in adult patients requiring tracheal intubation for anesthesia, in terms of intubation success, glottic view quality, intubation failure, intubation time, conversion to another laringoscopy method and adverse outcomes related to tracheal intubation.

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 110 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Intervention Model Description: Prospective randomised
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Can Videolaryngoscopy be the First Choice for Tracheal Intubation in Patients With Diabetes
Actual Study Start Date : May 9, 2018
Actual Primary Completion Date : May 31, 2019
Actual Study Completion Date : May 31, 2019

Arm Intervention/treatment
Experimental: Videolaryngoscopy
Videolaryngoscopy the trachea will be intubated using a videolaringoscope
Device: Videolaryngoscopy
Patients will be intubated with the video laryngoscope

Active Comparator: Direct laryngoscopy
Direct laringoscopy the trachea will be intubated using a laringoscope
Device: Direct laryngoscopy
Patients will be intubated with the direct laryngoscope

Primary Outcome Measures :
  1. intubation time [ Time Frame: 0-120 seconds after intubation ]
    The time elapsed between the passage of the larygoscope through the teeth and the detection of ETCO2

  2. first-attempt intubation success rate [ Time Frame: first second after intubation ]
    successful intubation with the allocated device

  3. intubation difficulty [ Time Frame: 0-120 seconds after intubation ]
    number of attempts, number of operators, number of alternative techniques, CL grade, lifting force, laryngeal pressure, position of the vocal cords,

Secondary Outcome Measures :
  1. glottic view quality [ Time Frame: during laringoscopy ]
    Cormack Lehane

  2. percentage of glottic opening [ Time Frame: during laringoscopy ]
    the percentage of glottic opening seen, defined by the linear span from the anterior commisure to the interarytenoid notch

  3. the rate of conversion to another laryngoscopy method [ Time Frame: 5 seconds after the first attempt to intubate ]
    the intubation device will be changed if the anesthetist fails to intubate with the allocated device

  4. adverse outcomes related to tracheal intubation. [ Time Frame: 1 minute after intubation ]
    Hypertension, tachycardia, desaturation, hypercarbia, airway trauma, laryngospasm, bronchospasm, sore throat,
