Instead of only carrying crystalloids, also carry hetastarch (Hextend ©, or an equivalent volume expander), which is a colloid and will stay in the vascular system longer and it will "expand" the blood volume. One 500cc bag of hetastarch is equal to 3 1000cc bags of crystalloid fluid.
So, back to fluids. There is still a need for crystalloids and that is dehydration and burns. We use a fluid replacement for burns at 2 to 4 ml per kg x percent burn give on half over first 8 hours from time of burn and the second one half over the next 16 hours for a starter and measure urine output.
Back to your question...500 or 1000cc, it does not matter and it is just a preference. Since I am treating burns and dehydration I will carry 1000cc bags as with even a min burn it takes a lot of fluid, example = a 70kg pt with 10% burn x 4ml will equal 2800 cc of fluid and one half will be 1400 given the first 8 hours. I spread the carrying of the fluids over the whole team as one man can not carry the load. Next question is how long will it take to extract.
Good luck, probably more than you wanted to know. If you have any more questions or if I need to clarify any point further please feel free to contact me....

Hola Mr. glenyork,
Thanks for participating in the medical forum...as a courtesy:
PLEASE FILL OUT YOUR PROFILE
so we have an idea of who you are, what your level of training is and the type of background you are giving your advice or experience from.
There is a wide variety of experience levels wihtin these boards, Trauma Surgeons, Anesthetists, Dentists, down to the buddy aid bubba.
Your statements regarding standards for trauma IV therapy may be fine for your current area of expertise or work, but if a battlefield injury comes to my BAS or Forward Trauma Team without a lifeline, it had better be because there wasn't even a piece of bamboo for that medic to sharpen and use as a needle. And with a systolic of 80 or less...decompensation is already well under way.
