Hypertonic dehydration

What is Hypertonic dehydration?
Hypertonic dehydration is the loss of water and sodium at the same time, but the lack of sodium than water, it is higher than the normal range of serum sodium, extracellular fluid status was hypertonic. When lack of water than sodium, the increase in extracellular osmotic pressure, increased secretion of antidiuretic hormone, renal tubular reabsorption of water increased, reduced urine output. Aldosterone secretion, sodium and water reabsorption to increase in order to maintain blood volume. Such as water shortages continue, extracellular fluid osmolality increased further, the cell towards the extracellular fluid, cells are finally dry than the extracellular fluid of the degree of water shortage. Water will cause the brain cells of brain dysfunction.

What're causes of Hypertonic dehydration?
There are causes of hypertonic dehydration include: a. insufficient intake of water, such as trauma, coma, esophageal disease, dysphagia, can not eat, inadequate water supply in critically ill patients, diet or infusion of hypertonic nasal feeding a large number of aqueous solutions such as hypertonic saline; b. excessive water loss, not in time to add, such as high fever, sweating a lot, a large area burns, tracheotomy, chest and abdomen visceral surgery Long time exposure, such as diabetic coma.
