Dehydration
SPECIAL CONSIDERATIONS:
1. Troops in the field are often chronically dehydrated.
2. Prolonged missions, acute diarrhea (gastroenteritis), viral/bacterial infections, and envi-
ronmental factors (heat stress or strenuous activity) all may exacerbate dehydration.
3. May also occur in colder high-altitude environments from dry air and hyperventilating
with vapor loss from breathing.
Signs and Symptoms:
1. Lightheadedness (worse with sudden standing)
2. Mild headache (especially in the morning)
3. Dry mucosa
4. Decreased urinary frequency and volume
5. Dark urine
6. Degradation in performance
Management:
1. Increase oral fluids if tolerated:
a. Use carbohydrate/electrolyte drink mixes for fluid replacement, diluted (1:4 solution)
b. Avoid fluids containing caffeine
2. If unable to tolerate PO fluids, use an initial bolus of 1 liter normal saline IV, followed by repeat
attempt at PO hydration. If still unable to tolerate PO hydration, repeat 1 liter bolus of normal
saline IV. If normal saline is not available, use available IV fluids.
DISPOSITION:
1. Monitor closely for recurrence of dehydration.
2. Priority evacuation if dehydration persists after treatment.
