What Is a Balanced Salt Solution?

A balanced salt solution is a salt solution in which the electrolyte content in the solution is similar to that in the plasma, and is called a balanced salt solution. Isotonic saline contains 154mmol / L of Na + and Cl-, while Na + and Cl- contents in blood are 142mmol / L and 103mmol / L, respectively. Compared with the two, the Cl- content of isotonic saline is higher than the Cl- content of blood 50mmol / L. In severe dehydration or shock, kidney blood is reduced, which will affect normal chlorine excretion. Intravenous infusion of a large amount of isotonic saline will cause blood Cl-to be too high and cause hyperchloric acidosis. Danger. Therefore, the use of isotonic saline to treat dehydration is inadequate, and the use of balanced salt solution can avoid excessive Cl- input, the treatment of dehydration is more physiological, and can help correct acidosis. Commonly used balanced salt solutions are sodium lactate and compound sodium chloride solution (1 / 6M sodium lactate solution 1/3 plus compound sodium chloride solution 2/3); and sodium bicarbonate and isotonic saline solution (1.25% sodium bicarbonate solution 1 / 3 and isotonic saline 2/3). ^[1]

The balanced salt solution is mainly composed of inorganic salts and glucose. Its function is to maintain the osmotic pressure balance of cells, maintain a stable pH and provide simple nutrition. The simplest BSS (balanced salt solution) is Ringer.

Balanced salt solution

Before the intestinal examination was performed by the hospital, the drugs were specifically used for bowel cleansing, so ordinary pharmacies did not sell them. Its main components are sodium chloride, potassium chloride, and magnesium sulfate, which produce a high concentration of electrolyte environment in the intestine. It attracts a large amount of water in the blood to the intestine through osmosis, thereby producing the effect of diarrhea. Very strong, the feces in the intestine can be basically emptied within a few hours. But it must not be used for weight loss, because it will have a great impact on the body's water and electrolyte balance, and even improper use may even be life-threatening. Similarly, other electrolyte solutions, such as those containing calcium ions, magnesium ions, etc., can be used intravenously.

0.9% sodium chloride sterile aqueous solution. Its osmotic pressure is similar to human blood, and the sodium content is similar to that of plasma, but the content of chlorine is significantly higher than the content of chlorine in plasma. Therefore, physiological saline is only relatively physiological, and its purpose is to supply electrolytes and maintain the tension of body fluids. It can also be applied topically, such as when cleaning wounds or changing dressings.
