What Is Fluid Replacement?

Rehydration is a medical term, a popular term for medical treatment of fluids. It is a fluid (such as glucose water, physiological saline, electrolytes, colloids, blood, acidic or alkaline liquids, etc.) that enters the human body environment through infusion devices or orally treatment method.

Rehydration is a popular term, medical term is fluid therapy,

Usually in the peripheral veins (commonly the back of the hand, arms, scalp in children). Mild cases can also be obtained orally (such as water, saline, potassium-containing fluids, oral rehydration salts). Large or rapid rehydration can be done with deep veins (

Hydration needs

Physiological needs: the amount of health a person needs, that is, not because of the need to treat a disease.

A patient with fasting water (without eating or drinking) has a normal daily physiological requirement: 5% glucose 1500ml plus 0.9% normal saline 500ml plus 10% potassium chloride 30-40ml.

Rehydration pathology needs

To treat different diseases, the amount of fluid is different. Patients in shock can infuse 10,000ml, mostly crystalline fluid and colloidal fluid and blood; diabetic patients receive infusions of up to 10% of body weight, mostly saline, and when glucose drops below 13.9mmol / L, 5% glucose can be given; Most infusions are more than 4000ml, mainly sugar water and colloids ...

Fluid dehydration

Divided into hypertonic dehydration, isotonic dehydration, hypotonic dehydration. According to the degree, it is divided into light, medium and heavy three degrees.

The treatments are different.

Fluid rehydration

There are many ions in the body, such as potassium, sodium, calcium and calcium, and their concentrations have a certain range. Too much or too little need to be adjusted, such as hyperkalemia, hypokalemia, hypernatremia, hyponatremia ... specific Treatment reference related links.

Disorders of acid-base rehydration

The pH of normal human blood, that is, the pH value, is always maintained at a certain level, and the range of its variation is small. Illness can cause acid or alkali. Refer to related links for specific treatment of acid-base disorders.
