Videolaryngoscopy vs Direct Laryngoscopy for Intubation in Patients With Diabetes

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.
