What is the use of dextro?

Question

do i need to be dextrose when for example i have an wound and many blood was lost?

Answer 1

Hmmm...  D5W which is an intravenous fluid will not restore the oxygen-carrying capacity of blood but will restore its volume so that proper pressure can be maintained.  Other IVs will also work for the same purpose  D5W means dextrose 5% in water.  With that, you should probably not be hungry.  

Depending on the amount of blood loss, transfusion might be more important, or for those whose religion prevent transfusions, a fluorocarbon fluid which can carry oxygen (sometimes called breathing fluid because it can be used in pressure suits for really deep dives).

Answer 2

Dextrose is just a sugar. If you can eat, you can take in sugars without the bother.

Answer 3

Dextrose means glucose. It means the solution predominantly rotates the polarised light to the right side. If there is a  heavy blood loss the blood should be transfused. Glucose has many uses.For example  When a diabetic patient haue taken insulin without taking breakfast, he will develop hypoglycemia. In this situation glucose is very useful.
