Enemas for rehydration?

Love it! Another zombie popped into my feed.

Yes, you can rehydrate via plain water enema (all the reasons already given), but you will rehydrate faster if you drink the water. In such cases speed is often a critical consideration.

Concerning the use of rectal administration to a wounded warrior on the battlefield - only if the patient cannot drink (unconscious or face/throat wound) and he/she is not gut shot.

The article states hydration for casualties during WW-I was common. IV’s weren’t available then but they are now used in the battlefield and are more effective. Medics carry them (IV’s) and in some cases they are carried in combat packs.

In combat or survival situations in the ocean salt water or dirty contaminated water can be used in enemas that orally could or would sicken or kill you .

Depending on how dehydrated someone is the colon can absorb up to approximately one liter (quart) per hour. no salt should be added.

when i am in the desert i will pre-emptively inject a liter as 'spare" ..
