Introduction:

Fundamental responsability of anesthesiologist is to secure and to maintain a secure airway. The complications that arise in the failure of intubation are cause of morbidity and mortality. The use of video laryngoscopes give us a better view of glottis, although it may increase the intubation time due to its shape. No studies have been found made in anesthesiology residents; most of the studies are carried out in experienced personnel in the use of video laryncoscopes.

Material and methods:

25 laryngoscopies were performed with each videolaryngoscope in patients over 18 years old, ASA I-III, without difficult airways predictors, under general anesthesia. The differences between hemodynamic variables (blood pressure, heart rate, oxygen saturation) as well as time and number of intubation attempts were determined.

Results:

We found statistical significance for the number of intubation attempts (p = 0.037) and for the intubation time (p = 0.011).

Conclusions:

The better handling was in favor of the Truview EVO, we could observe a greater difficulty to introduce the endotracheal tube in King Vision. The results obtained in our study are comparable with those obtained in other studies perform in experienced personnel.
