What Is Fluid Retention?
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.
