title: Laryngeal problems in space travel.
abstract: A start has been made in enumerating possible problems of the larynx, in short or moderately long space voyages, based on our current knowledge of laryngeal diseases. The gravity-free state does not seem to be a threat to the physiology of the larynx. A relatively nonspecialized medical team must be able to recognize and manage Earth-type diseases. They must also be capable of managing both the special problems associated with various degrees of decompression sickness and the increased possibility of inhaling a foreign body, which are inherent in the gravity-free state. In crew selection, a special attempt should be made to eliminate those members with an increased risk of laryngeal disease development. Simplified methods of examining the larynx, including flexible fiberoptic laryngoscopy, should be available. Airway management, including coaxial endotracheal intubation with a bivalved laryngoscope, would be possible. An audiovisual tape library of simple and moderately complex procedures would be highly valuable.
