John is entombed in some sort of concrete mold, lying on his back. There is a hole in the concrete with a tube for breathing, a hole with an Iv going in to his arm, and some sort of waste disposal system (catheter + hole in concrete, hole below butt for solid waste disposal).
How long would someone stay alive like this? What would kill them first? Would their blood eventually clot from lack of movement? Would circulation get cut off to parts of the body?
Concrete gets really fucking hot when it cures. If he was placed in it before it set, he’d be cooked alive.
There would also need to be room for chest expansion, or suffocation would happen pretty quickly I’d imagine.
I would think the alkalinity of the uncured and curing concrete would kill you with full-body exposure before anything like blood coagulation would. The pH of fresh concrete can be as high as 13 or 14, which is as alkaline as lye.
Hmm, okay. Maybe a pre-molded shell in two halves that’s closed once the victim is placed in there?
The point is, breathing, feeding, and waste are taken care of, but head, arms, and legs can’t move, and there’s sensory deprivation as well.
Even disregarding the issue of concrete heating up when it cures, the body does produce heat, so it would still get really, really hot in there, leading to sweating. No real air circulation so it just keeps getting hotter.
Edit - this wasn’t my idea. I heard it on another board as part of a two-sentence horror story.
Seems to me there was a Grey’s Anatomy episode concerning this.
I’d think you could survive for quite some time, though.
The heat as well as the leaching of liquids from your body would be big problems - you’d have to be pumping a lot of fluids in, and I don’t see that going well for very long.
If nothing else, I don’t picture that catheter and IV line remaining infection-free. Are we doing just dextrose, TPN (amino acids/nutrients/minerals), or can we put drugs in there too? What kind of monitoring? And are we actively trying to keep the guy alive or are we doing the bare minimum maintenance and lettin’ him go?
I assume that with proper nutrition, some anticoagulants/other drugs when needed and keeping that concrete at a comfortable temperature, he might die of boredom.
Is there some reason for the concrete enclosure, or were you just imagining the person being immobilized?
If it’s a cured shell in a room temperature environment heat loss is going to far more of problem than heat retention as the mass of the concrete at room temp (say 80 degrees) will be a huge heat sink and will pull heat away from the body via skin contact far more efficiently than air.
If the person is awake (not drugged) and in complete darkness (or complete light) without being able to move, I think he’d go insane in a couple of days. BBC did a docu once where they put a couple of volunteers in sensory deprivation rooms - dark, goggles, headphones, gloves - with a bed. First they tried to sleep really long, but soon after, they had auditory and visual hallucinations. It was 24 or 48 hrs, so not really long, but the volunteers were all shaken and in bad shape (did really bad on memory and concentration tests afterwards compared to before). The amount of how much it influenced the subjects was a surprise both to them and to the testers (and shows why sensory deprivation is such a “good” = effective white torture method).
A wild Doper appears!

With no movement allowed at all, thrombosis is going to set in within a few days. After that it’s a toss up what will kill you first: the embolism, the necrosis or the loss of clotting factor.
Even with all the drugs in the world, the bedsores are gonna be lethal within a few months, probably within weeks. Lying on a solid material composed of grains of square-edged sand with no way to relieve pressure and no way to keep it dry? Bedsores are gonna develop within days, they’re gonna be open lesions within a week. And because they are caused by a lack of blood flow all the IV drugs in the world won’t heal them. Even if you could keep the person so full of antibiotics that the infection couldn’t spread to the bloodstream, they will still die because: 1) The ulcers will spread, and once you have 10% of you body covered in weeping ulcers you will be losing galloins of water an hours. 2) Even if you can keep the live bacteria out of the bloodstream, the autolytic breakdown products are going to kill the victim either through anaphylaxis or by overloading the liver kidneys trying to detox that crap.
My semi-educated guess would be a week max before thrombosis causes death, and if you can treat that then maybe a month before the ulcers become fatal.
Incidentally, I was recently reading of something similar, used by Abu Nidal’s terrorist organisation on its own members suspected of disloyalty:

If I managed to make it to “a few days”, I’d already be wishing for death. Then again, I may have a lower threshold of boredom.

Coma patients seem to survive okay.
That’s basically the same situation as a patient who needs an iron lung to stay alive.
The world record for survival in an iron lung is 60 years.
Coma patients are unconscious.
It’s nothing like an iron lung. Patients in iron lungs have as much mobility as a bedridden patient who is not in an iron lung. They are able to turn over, flex their limbs, stretch their spines, lift their arms and legs above their heads and so forth. Basically anything that you can do without getting out of bed, a patient in an iron lung can do.
In contrast, in the situation described int he OP the victim cannot so much as raise a single finger or turn his head.
