Considerable planning has to be made prior to the onset of the medical operation and this planning should be made in conjunction with personnel familiar to the locale as well as to the needs of the personnel. Sanitation and waste disposal present a problem in a temporary operation such as this. Permafrost is constantly present and many accepted methods of disposal are impractical in this situation. In general, health matters seem not be appreciably altered from other locales. Respiratory infections, minor trauma, and dental complaints comprised the majority of patients seen. Weather conditions make air evacuation undependable and overground or oversnow vehicles the most reliable. Medical problems that arise appear essentially unchanged from medical problems arising elsewhere. More personal concern of health from unit leaders and individuals is mandatory for future good health of the unit. Minor alterations in equipment and packaging of supplies is needed for an operation of this type.
