well, there has to be a change in osmotic pressure for fluid to move from one place to another. isotonic loss of fluid will not change the osmotic pressure, and thus there will not be an osmotic difference between the EC and IC compartment, and no fluid shift

isotonic fluid loss such as hemorrhage,vomiting,diarrhea....water loss is from either plasma or interstitial fluid(only ECF).....but there wont be change in solute concentration as water shifts from interstitial to plasma(as in the case of hemorrhage) likewise viceversa...........so as there is no solute loss, ICF wont change(as shifting depends on mainly solute changes not water changes)
only ecf will change...so isotonic saline would be helpful for treatment (increase only in ecf....like 0.9% nacl....volume expanders).....
i hope it will be helpful........
