I have v difficult veins for ivs, even if they get one they collapse asap. i need iv fluids soon, how unreasonable is it to ask for a different sort of access? i just know i don't want another 6 in 24 hours that all collapse?

There are several alternatives to repeated IV puncture, but it depends on why and how often you need IV access. Usually, some form of an indwelling line is used. They are not without their own complications but the benefit of more permanent IV access will often outweigh the risk of repeated venipuncture.

It would be much more reasonable to focus on avoiding the need for iv fluids or trying to treat the cause for getting dehydrated. For this reason, your request will sound suspicious to hospital staff.
