Ha valaki kórházban hal meg, miért nem csapolják le a vérét? Ez megoldás lenne a vérhiányra?

A legfőbb ok szerintem az, hogy nincs hagyománya a dolognak és idegenkedik mindenki a gondolattól. Ezt találtam közben egy reddites fórumon válaszként:

"I work for the organ and tissue donation industry. Blood banking is separate from us but most of our regulations are based on the blood banking industry.

If cadaveric blood is usable- the bigger issue is getting it. We have to draw blood on all of our deceased tissue and eye donors. We do it using a spinal needle and a 60cc syringe and usually draw from their subclavian or femoral vein, and sometimes from their heart.

Two issues because the person is dead: 1) no pulse. It's nothing for us to sit there and donate a pint of blood because we have a beating heart and our blood is moving through our veins, there is internal pressure that will force it through that awful needle and into the bag. Once you die, your blood stops flowing and starts pooling in your body, that's lividity, or the red-purple patches on dead bodies. So, oftentimes, we have a very difficult time getting blood out of the cadavers heart, especially if they were dehydrated when they died- their blood is pooling in their capillaries, and our "little" syringe does not have enough power to pull it up. 2)Blood clots. It starts clotting at different rates for everyone and the medications a person was on when they died can affect how viscous their blood is.

Next. Consent. It's easy when you're alive because you can answer for yourself. When we do organ, tissue, or eye donation, we have to contact a family member to authorize the donation, even if you've signed up at the DMV. Then, we need a Donor Risk Assessment Interview (DRAI) completed by the family. It's a ton of questions very similar to those asked when donating blood, but a bit lengthier. If an organ donor doesn't have this, it's fine, and the organs are listed as "high risk." For tissue and eye, it's necessary because tissues have been deemed as life-enhancing, not life-saving and so the risk-benefit analysis doesn't make high risk tissues a necessary risk. So, we would at least need the questions required for blood donation answered.

Next: Timing. It can take us a long time to get ahold of the family of the deceased. They are going through a lot of trauma and sometimes, donation is the last thing on their mind. And all that time it takes for us to reach them, the body is typically put in a morgue cooler, which is not good for blood viscosity. Our paperwork takes at least an hour to complete, to where we can then send a tech out to wherever the body is, hopefully draw enough blood, and then ship it to processing.

Edit: Also, Contamination. Once your immune system dies your microbiome immediately starts taking over and you start decomposing. Blood can still be used for serology testing at this point or even if it's come in contact with other bodily fluids, but I doubt it would be safe to transfuse it into a live person after a certain timeframe- which would need to be validated."
