The Oxford Fibreoptic Teaching Box

Mastering fibreoptic skills requires not only a thorough understanding of the working principles of the instrument but a lot of practice in manipulation skills before performing procedures on patients (1). The main objective is to understand how the different manipulations at the body of the fibrescope are translated to the tip of the fibrescope.

Developed by an experienced team of trainers in fibreoptic intubation in Oxford, this box is an example of a dhit the hole' teaching aid. This cylindrical box is made of perplex and has 5 plates each drilled with a number of holes, the size and combination of which is precisely designed. The size and arrangement of the holes in the box is selected so that the tip of an adult tracheal incubating fibrescope (e.g. Olympus LF-2 or GP, Pentax) just passes through them only when actively manipulated. The holes have chamfered edges to prevent damage to the fibrescope.

The effectiveness of the box in improving fibreoptic manipulation skills has been confirmed in a randomised controlled trial (2). When assessed on an incubating manikin, trainees who had practiced on the box showed significantly better manipulation skills than trainees who had not.
