Infusion fluids do not damage blood, Why?

Hello All Steemian around the world..
I hope you are healthy and full of blessing.
Today I visit my niexe at hospital. She has fever and must be hospitalized for some days. We visit her with my son.

When he saw his cousin being given an IV drip he noticed the fluid flowing through the IV tube. He looked at the drip after drop that continued to flow. He saw this fluid enter the body through a needle that was injected through his arm.

"Father, why are IV fluids that enter the body not rejected, even though IV fluids and blood are completely different types. Why don't IV fluids damage blood cells or blood fluid?"

I was surprised to hear that question. However, I was also proud to hear him ask something like that. One sign that he has high curiosity. A good sign that a child has a high interest in learning.

Isotonic fluids

Finally, I asked him to leave the room and then explained it so that his knowledge would increase.

I remember biology lessons at school. The infusion given to patients is safe and does not damage blood plasma. This is because the infusion fluid is an isotonic fluid The isotonic fluid in the infusion is applied to the patient via intravenous injection. In patients treated in hospital.

The isotonic fluid in the infusion has an osmolality value that is almost the same or balanced as blood plasma. With the same osmolality, the injected infusion does not damage blood cells. Likewise, infusion fluids do not damage blood vessel endothelial cells.

This isotonic infusion fluid is very useful for increasing the amount of fluid in the body. Lack of fluids, either plasma or nutritional integrity, can occur due to blood loss due to wounds, surgery, or dehydration.

By giving an infusion, you can meet your nutritional needs. That's why patients in hospital, even though they don't eat much, can still survive because there are IV fluids that are injected into the body.
After I explain about the reason of undamage blood vessel caused by IV my son looks satisfied.
I jus smile when saw him.

That all my writing this time. may useful for all of us.

Thank you for stopping by and reading my post

Warm regard from Indonesia
