would be improved by appropriate use of electrolyte-carbohydrate solutions under field conditions.

Below are the committee's recommendations developed following the workshop:

  • The solutions should provide approximately 20 to 30 meq of sodium per liter, 2 to 5 meq of potassium per liter, and chloride as the only anion.

  • The carbohydrate content should be provided as glucose or sucrose, malto-dextrin, or other complex carbohydrate in a concentration of 5% to 10%.

  • The value of additional magnesium, bicarbonate, and phosphate to compensate for gastrointestinal losses due to diarrhea or other gastrointestinal disturbances should be determined.

  • The promotion of fluid intake with such palatability and psychogenic aids as flavorings and colorings should be evaluated with respect to the promotion of fluid intake. The components of the solution must be compatible with halogens or other water purifiers.

  • A variety of training and field operations should be considered as a means for evaluating the effectiveness of prototype electrolyte-carbohydrate-containing solutions under the following conditions:

    • When soldiers are in significant negative caloric balance.

    • Under conditions of hypohydration.

    • When the solution is the principal beverage available.

    • Under conditions of environmental extremes, especially those conducive to stress. Interventions for prevention and therapy of heat-related disorders should be evaluated.

    • When used by soldiers previously on a low sodium diet (less than 3 g/day) who are suddenly exposed to hot or humid environments and who are performing heavy physical activity.

    • Under field conditions when halogen-treated water is likely to be available. Do any of the components in the prepared solution interfere with purification of the water? Is the resulting beverage sufficiently palatable to ensure an intake adequate to prevent significant hypohydration?
