Deletion of Deep hypothermic circulatory arrest

Comment: For now. Yes, these techniques are both about cooling, sort of like model rockets and Apollo Program are both about rockets. But in practice they are quite different procedures, are not done by the same people (it would be a disaster if they were), and have quite different goals. DHCA is done by major vascular surgeons, and it cools way down till the heart stops so (very fast) surgery can be done without blood pressure. The other technique cools a little to get some effects of cooling on the brain, but the goal is NOT to stop the heart. The DHCA article will probably need to be expanded when the EPR-CAT trial results come in. The emergency people are pushing the latter term EPR (Emergency Preservation and Resuscitation) for the trauma procedure in which a patient arrives to the ER with a penetrating wound to the chest which can only be fixed after an (otherwise fatal) period with no blood pressure, and so "DHCA" is induced emergently with cold washout (rather than in a controlled way, as is done for aneurism repair). But here, the U. Pittsburgh people who got the grant money to try this in humans (after success in pigs) want to call it something else. http://www.popsci.com/article/science/how-it-works-putting-humans-suspended-animation. People trying for grant money always want to split so they can have their own cool term (sorry), and people who aren't getting the money always want to lump.  Speaking of lumping, it's also fine with me if the articles are merged, provided the DHCA material all gets put into the Targeted_temperature_management article and gets its own section (despite comments above, the DHCA material is certainly NOT covered in the Targeted_temperature_management article, one major reason being that DHCA sometimes does not aim for a targetted temp which is managed, but cools much as one can till before you are stopped by other circumstances).  But after EPR results are added, this thing is going to be too long, and somebody will be back here again, saying we should have a split per , and somebody else will wonder whose idea it was to shove these different things together in the first place
