What Are the Different Types of Dehydration Treatment?

Dewatering is a chemical unit process and a reverse process of hydration. It is relatively easy for pure hydrates to release water molecules from material molecules. Generally, it only needs to be heated to remove water from evaporation. If sodium carbonate hydrate crystals are heated, they will be dehydrated into sodium carbonate powder. But for a new substance that is only combined with water molecules, dehydration must be aided by a catalyst or other conditions, such as dehydration of ethanol to ethylene or ether.

Hypotonic dehydration has more sodium loss than water loss, serum sodium concentration <130mmol / L (<130mEq / L),

When water and sodium are lost in proportion to their concentration in normal plasma, it can cause isotonic dehydration. Even if it is not proportionally lost, it is adjusted by the body after dehydration. Those whose blood sodium concentration is still maintained at 130-145mmol / L and osmotic pressure is still maintained at 280-310mOsm / L are also isotonic dehydration. Cause and mechanism

No matter what type of dehydration, they are dehydrated first, that is, there is a decrease in extracellular fluid volume. Extracellular fluid accounts for approximately 20% of normal body weight and intracellular fluid accounts for 40% of body weight. Extracellular fluid is divided into plasma (5% of body weight) and interstitial fluid (15% of body weight). Under normal circumstances, the volume of fluid between different individuals is quite large, which is mainly determined by age, sex and obesity. The distribution of plasma interstitial fluid and intracellular fluid is relatively stable, and they are constantly exchanged. A layer of plasma and interstitial fluid

People with normal thirst rarely get hypertonic dehydration when they can get and drink water, because in the early stage of water loss, when the plasma osmotic pressure is slightly increased, the thirst center will be stimulated . After drinking water, plasma osmotic pressure can be restored. Dehydration

1. The primary disease should be prevented and prevented from acting for some reason.

This is a chemical change, also called corrosion. It refers to the hydrogen and oxygen atoms in the substance, according to the composition ratio of water molecules (H20), which is hydrogen: oxygen = 2: 1.

It is not water molecules that are removed in this process, but the hydrogen and oxygen elements in the material.

For example, concentrated sulfuric acid has strong dehydration ability, which can remove the oxygen and oxygen elements in paper, wood, skin, and sucrose (composed of the three elements of CHO). As the HO element is gone, only the C element is left. It becomes black carbon.
