Method Draining Blood With Syringe

[Gorgon]

Do you think it's possible to drain your own blood as a way of CTB? Like if you took a syringe needle and stuck it in an arterie in your neck and tape it would it drain enough blood to kill you? It seems minimally painfull although messy.

Not a reasonable idea, no. It would be possible, technically, but it's also possible to die by ingesting enough plastic debris, or enough pennies or too much water.

For reference, losing 40% of your blood is usually fatal, and the average adult has 4.5 to 5.5 liters of blood, which would mean about 2 liters (half a gallon or so) of blood loss. Donating blood involves giving between 300 and 500 mls of blood, and if you've ever given blood, you know it actually takes a while to get that amount out of you with an IV. You'd need to extract at least 4 times more to deliberately die, and the more you extract, the slower it goes, because less blood means less blood pressure and a slower flow rate.

One of the more interesting case reports I've read about suicidal exsanguination was a doctor who injected himself with lidocaine (a local anesthesic) near the femoral artery, and then cut the femoral artery with a sharp blade... I've personally considered this method - basically painless, minimal risk of serious injury in the event of failure, likely to be highly effective.

Ok then could you say replace the lost blood with saline water to keep pressure? One arm has a big bag of water attached and the neck has the "drain" if the water was above body level and the neck was close to the lowest point I imagine you could get most?
Blood pressure is written as two numbers, such as 112/78 mm Hg. The top, systolic, number is the pressure when the heart beats. Aproxamintly 51 mm hg is equal to 1 psi so the human blood pressure is typically no more than 2 psi. It takes a 2.3' column of water to create 1 psi so as long as you has a hose 4.6' that was always full of salt water you would have adequate pressure.

I used to self harm this way. At my worst, I lost around 2L of blood in ten days, in three sessions of around 600-800mL. I had to go to ED and have a blood transfusion. So I say this not only as someone with medical training (I'm qualified as a paramedic), but also personal experience...

I managed to cannulate an artery twice with a large gauge cannula. Not much happens. The blood changes colour, but that's pretty much it. You need very specific equipment and skill to place a catheter in or cut an artery effectively. Often they run quite deep, and it would be a challenge to do this yourself.

I lost the bulk of my blood through cannulating large veins. To loose the 600 - 800mL each time, I'd sit at the bottom of the shower with my arm low to encourage blood flow, and let my blood drain into a container. This is not a pleasant experience, and would take hours to kill you if you let it continue. You will get hypovolemic shock - I did - and feel nausea, chills to your very core because there's not enough blood to keep you warm, your extremities will start to get pins and needles before cramping up. You won't be able to move without feeling absolutely exhausted and sweating profusely, because again, there is not enough blood anymore. Blood is effectively an organ. It has important shit to do, and you feel rotten without enough of it

Hypothetically, you could do this. But it wouldn't be easy or painless at all

Literally just yesterday I read an article about a young nurse with personality disorder killing herself by draining her blood. Seems like an efficient method if you try hard enough.

You always see stuff like that in tv shows and movies. I remember a episode of a show where a guy has to do a blood transfusion for his son that is losing a lot of blood and the doc says if he dosen't stop giving blood he would die

Yes, always pays to remember that TV and movies are entertainment products, not educational products... especially when the consequences of doing it wrong can include permanent injury.

So I wonder if you could take a blood thinner with barbiturates to knock you out and just bleed out.
