Why?

why normal saline use to treat DKA i know that D5W with insulin and Kcl used to treat DKA?
why mixing dextrose with blood cause hemolyze?

5% dextrose solution is also considered hypotonic compared with blood, because although it is isotonic while infusing, the dextrose is metabolized and free water is left, which is hypotonic. too much internal pressure, caused by water, will come from a hypotonic solution. when there is more concentration of water outside of a cell, it will compensate by taking in as much as possible to reach its equilibrium. if the pressure is too great, the cell will rupture.hope this helps.

Check out this link : Diabetic Ketoacidosis: eMedicine EndocrinologyAlso, this one: Diabetic Ketoacidosis: Treatment & Medication - eMedicine EndocrinologyFluids: Initial correction of fluid loss is either by isotonic sodium chloride solution or by lactated Ringer solution.....I hope this helps!

Boy, with all the help you are getting on your homework, you should be done with nursing school in no time.

This is off the topic, but...pansyrose, I love your "I want to know, I want the answer now, and why" lines. You make me chuckle to no end. I hope the service here in AllNurses have been pronto (or stat) enough for ya. My guess is that too much sugar is really bad for people who suffer from DKA...so salty water it is!

I dont like your comment.you are silly

D5W is hypotonic, and a solution of a lower concentration will automatically diffuse to a higher concentration, and so D5W can lead to hyponatraemia which may cause cerebral edema.
