[Difficult intubations and proposed solutions. Intubation by fiberscopy]

After a review of the various techniques used in difficult intubations, the authors emphasize recent progress in the field of fiber endoscopy. The advantages of this technique, e.g. absence of trauma, increased field of exploration and reduction in dose of anaesthetic drugs, exceed the present disadvantages, e.g. high price of this material, relatively fragile apparatus, too long and diameter too great for use in children.
