Re: How to stop bleeding from cuts and swelling?How do I dectect bloodclots etc

-- On controlling bleeding:

This is most commonly done with a styptic pencil.  These are available
in any pharmacy.  They usually consist of iron or aluminum sulfate, which
when applied to a small cut causes constriction of the blood vessels.
Please note that this is useful for *small* cuts.  Very large cuts must be
stitched, and I do not recommend trying that on your own.

I've not found information on "homostatic" products; did you perhaps mean
"homeopathic"?  These, for the most part, are simply glorified styptic
pencils.  

-- On controlling swelling:

As for the cold metal, an ice pack would do just as well, and is probably
more comfortable for the boxer.  It works the same way, by constricting
the blood vessels at the site of the wound and preventing fluid from 
building up in the tissues.

-- On continuing to fight with a broken hand:

I'm not going to touch this one with a sixty-foot pole.

-- On identifying a broken bone:

The first sign is pain, and lots of it.  Another sign is swelling.  Another
is deformation -- the hand may bend in a place that it's not supposed to.
Yet another is crepitus -- the broken ends of the bone can be heard (and
felt) grating against one another.

-- On identifying blood clots:

This cannot be done easily at ringside.  It requires x-rays or CAT scans.
A sharp pain or numbness might be a sign of a blood clot, but I imagine
these are both common in boxing.

I would recommend going to the library and looking in the card catalog 
under the heading SPORTS MEDICINE.  You can also search the World Wide Web
for those two terms.  It is a very active field of medicine these days,
and I am certain you could find enough information.
