4hw.com.cn: we will inevitably encounter bumps and bumps in our daily life. Many people will choose to use normal saline for disinfection. What is the difference between normal saline and normal saline? What are the effects and functions of normal saline?
What is normal saline
Physiological saline is also called aseptic physiological saline. Its osmotic pressure is similar to that of human blood, and the content of sodium is similar to that of plasma, but the content of chlorine is significantly higher than that of chlorine in plasma. Therefore, physiological saline is only more physiological, and its purpose is to supply electrolyte and maintain the tension of body fluids. It can also be used for external use, such as cleaning wounds or dressing change. 0.9% normal saline can maintain the normal morphology of cells.
The difference between normal saline and normal saline
It is different from ordinary salt water except for salt content;
Physiological salt usually refers to 0.9% sodium chloride aqueous solution, which is used for medical purposes. Of course, its purity and concentration are strictly required. There is no other addition. If you want to eat it, it is OK, meaningless and wasteful. Edible salt, salt for general use, even refined salt, has a lot of poor purity, and some things like iodized salt have been added specially.
Does saline have antiphlogistic effect
Physiological saline has the effect of disinfection, so if you have rhinitis, you can use physiological saline to clean the nasal cavity, which can play a very good disinfection role. If you want to use normal saline, you'd better not do it by yourself, because you can't control the concentration properly, and it will cause too much concentration and damage the nasal cavity. You just need to go to the drugstore to buy it. At the same time, when using normal saline, it must be used with the help of doctors. At the same time, it can also be replaced by chloramphenicol eye drops, and the effect will be better.
Effect and function of normal saline
1. Avoid cell rupture
The osmotic pressure of normal saline is the same as that of extracellular solution, which will not cause the cell to break due to dehydration or excessive water absorption.
2. Clean the wound
In fact, normal saline is low concentration saline, which is often used to clean wounds and replenish blood volume.
3. Correct acidosis
The method of alternate static point with normal saline and 5% or 10% GS solution can supplement electrolyte, correct acidosis, overcome ketosis, and supplement water and heat card.
4. Maintain the tension of body fluids
Physiological saline can supply dielectric and maintain the tension of body fluid. It can be used for rehydration and other medical purposes. It is also commonly used for in vitro culture of living tissues and cells.
The medicinal value of normal saline in the treatment of rhinitis is generally only used for atrophic rhinitis. According to the curative effect of normal saline, metabolic alkalosis can be divided into two categories: effective metabolic alkalosis treated with normal saline and ineffective metabolic alkalosis treated with normal saline.
