It is made according to the concentration of saline in the human body
It can be drunk or injected
Saline prevents cells from rupturing, and its osmotic pressure is the same as that of extracellular fluid
Saline doesn't dehydrate or over-absorb the cells, so it's used for many of the various medical operations where fluids are needed.
Formulation 1 Saline for various animals
Mammals The concentration of saline required is 0.9%. Weigh 0.9 grams of sodium chloride, dissolve in a small amount of distilled water and dilute to 100 ml.
Birds The saline concentration required is 0.75%. Weigh 0.75 g of sodium chloride, dissolve and dilute to 100 ml with distilled water.
Amphibians The saline concentration required is 0.65%. Weigh 0.65 g of sodium chloride, dissolve and dilute to 100 ml with distilled water.
Formulation II Ringer's Saline
Sodium chloride 6.5 g sodium bicarbonate 0.2 g
Potassium chloride 0.14 g sodium bicarbonate 0.01 g sodium dihydrogen phosphate
Calcium chloride 0.12 g
First, dissolve sodium chloride, potassium chloride, sodium bicarbonate, and sodium bicarbonate in a small amount of distilled water. dissolved in a small amount of distilled water, mixed and diluted to 980 ml with distilled water. Then take calcium chloride dissolved in 20 milliliters of distilled water, add the calcium chloride solution drop by drop to the above solution, while dropping, while stirring, so as not to produce undissolved calcium phosphate precipitation.
This solution is used for variable temperature animals, especially commonly used for amphibians.
Formulation III Locke's saline
Sodium chloride 9.0 g sodium bicarbonate 0.1-0.3 g
Potassium chloride 0.42 g calcium chloride 0.24 g
Dissolve sodium chloride, potassium chloride, and sodium bicarbonate in a small amount of distilled water, mix them together, and add distilled water to 980 ml. . Dissolve calcium chloride in 20 ml of distilled water and add it drop by drop to the above solution.
The above solutions are used for thermostats and are especially commonly used for mammals.
