    ObjectivesIn fibroscopic intubation, the fact of achieving a direct view in real time does not guarantee the correct advance of the endotracheal tube (ET) to its intratracheal position. The use of oral cannulas helps in achieving a free airway in order to pass the fibroscope and the ET. This study compares the VAMA(®) (V) and Berman(®) (B) cannulas as regards the time required for the intubation, fibroscopic view, and the ease in positioning the ET.Patients And Methods90 patients with no signs of difficult airway were randomised into 2 groups, Berman(®) (B) and VAMA(®) (V), depending on the type of cannula employed. After inducing general anaesthesia, they were intubated using a flexible fibroscope. The fibroscope and intubation times were recorded, as well as the quality of the fibroscopic view, and the level of difficulty in positioning the ET.ResultsNo statistically significant differences were observed between the cannulas, although the intubation time (P=.292) and the difficulty found in positioning the ET were slightly less (P=.447) in the VAMA(®) group compared to the Berman(®) group. The vision quality was good with both devices, with only some degree of obstruction being encountered in only 22% of the patients. In no case was there complete obstruction, thus all the patients could be intubated correctly.ConclusionsThe VAMA(®) cannula is an effective alternative to the classic cannulas for fibreoptic assisted intubation. Furthermore, the novel design provides advantages for the correct orientation of the fiberscope and the withdrawal of the cannula after intubation.Copyright © 2011 Sociedad Española de Anestesiología, Reanimación y Terapéutica del Dolor.
