Why is Saline used?

Question

Why is saline often put into the blood and why is it often warm?

Thank you

Answer 1

"Normal" saline (0.9%) is isotonic with normal body tissues, which is to say that it will not draw water out from body tissues causing dehydration, nor will it cause water to enter body tissues unnecessarily (overhydration). Dextrose 5% and half-normal saline IV solution is also considered isotonic.

As another posted (and I missed the "warming" aspect in your question originally,) it is warmed only to prevent a sudden drop in body temperature in suseptible patients (I worked on inpatient med-surg units where IV solutions were rarely warmed.

Answer 2

it's isotonic. matches your plasma.

Answer 3

its clean

Answer 4

It is isotonic with blood. It replenishes fluid & certain electrolyte loss.Any fluid to be pushed in to the system should be at body temperature to avoid rigors &chills specifically when a lot of fluid is to be replaced.

Answer 5

normal saline is an isotonic solution, so it is used when there is need to increase the blood volume without changing the the osmotic pressure of the blood, and it is warm so it won't increase or decrease the body temperature.

Answer 6

it cleans out impurities....I do believe

Answer 7

It supplies water and salt (essential).

This means that it is often used for dehydrated people.

I guess if it is warm, its because its going straight into the blood, so if it were colder than the blood, it would lower your blood temperature.

Answer 8

It's used because all doctors are told that it is isotonic with body fluids, as several people have explained. But it isn't - it actually has a high sodium and chloride concentration (154mmol/L in 0.9% saline). So I don't really know why it's used!

Answer 9

to give some flavoring ,the vamps hate unsalted blood.!!

Answer 10

Because our blood is basically salt water with some other chemicals and cells mixed in. Saline is a cheap approximation of what our blood is made of.

It is warmed because you can drop a patient's body temperature by giving a large volume of "room temperature" saline, which is 20-30 degrees F cooler than body temperature. Warming is not routine, but is often used in trauma patients or with small children.
