[Use of a single-use fiberscope for the training in tracheal intubation under fiberscopy on labyrinth]

Goal of the study: To evaluate a single-use fiberscope, the Ascope-Trainer, for the training in the intubation under fiberscope.

Type of study: Prospective randomized study approved by the local ethic committee.

Methodology: After evaluation of their level of expertise, "experienced" or "novices" in intubation under fiberscope, the doctors attending the Training for Referents in Difficult Airway Management performed a test on labyrinth with a standard fiberscope (T1). After they were assigned to two groups, training with the Ascope-Trainer (group A, n=35) or with a classic fiberscope (group C, n=29), they trained during 15 minutes and performed a new test (T2). An analysis of variance was used to compare means. A goal for the training was determined according to the "experienced" doctors' mean T1. A test of Khi(2) was used for the comparison of the number of participants having reached this goal as well as the progress in both groups A and C.

Results: The T1 in the "experienced" group was 76 ± 31 s and the training improved significantly T2 (53 ± 17 s). Considering the novices, T2 was significantly lower than T1 in the group A (77 ± 38 s versus 135 ± 68 s) as well as in C (64 ± 28 s versus 122 ± 60 s), and the proportion of the novices having reached the goal of training was comparable in both groups.

Conclusions: Because its use is similar to the standard fiberscope, the Ascope-Trainer may be interesting for this type of training.
