Fever due to an influenza A infection outbreak in Amazonas demonstrated that patients with fever had a significantly increased reactance and decreased resistance and impedance that may be attributed to a decrease in the extracellular water
Total body water and intracellular and extracellular water were also significantly decreased especially during 4 weeks, suggesting that weight reduction for 0-4 weeks from baseline was mainly dependent on water loss.
Since intracellular and extracellular water was equally reduced, reduction of both water might have been related with the reduction of body weight.
The fast distribution volume of glucose is not altered by insulin and it includes the plasma volume and extracellular water of highly perfused organs.
Prolonged overexpansion of extracellular water in ederly patients with sepsis.

Extracellular water decreased near significantly (p = 0.05) from 20.6 Liters to 18.5 Liters, a 10% drop (Table III).
Consistent with this use of stored nutrients are shifts in intra- and extracellular water
, and findings by Finn et al.
Assessing total body and extracellular water
from bioelectrical bioelectrical response spectroscopy.
The extracellular water
content is approximately 45% of the body weight in neonates compared with 20% in adults.
A physiologic decrease in extracellular water
volume, as well as a transient increase in serum potassium and transient decreases in plasma glucose and total plasma ionized calcium concentrations must be taken into account.
