While it is true that many head wounds bleed profusely, it is not a necessary thing. I have seen head wounds that bled so badly, even wrapped in
towels, blue pads on the bed, and compression dressings, there was a huge puddle of blood under the bed. They had four simultaneous IV's running, one
in each arm, one each side of the groin, with blood running in full speed, nurses even compressing the bags, yet, the patient bled much faster than
they could get the blood in. There are major arteries in the brain, and a place where they all come together, called the Circle of Willis. This
happens to alao be a location of anyeurisms, as well as major stroke blockages. Once these arteries are severed by trauma, a head wound can mean
sudden death if the patient is not treated quickly, and the arteries repaired quickly, the patient will die. If it is irreparable, the transfusions
are stopped, and the patient dies quickly.
However, not all head wounds are equal. I have also seen what amounts to self cauteruzing head wounds from point blank gunshots, where there is hardly
any blood. The gunshot itself is fatal, the bullet fragments, and literally rips the brain to shreds, but the blood release is quite minimal. Simply
the trauma is enough, or, even sometimes, the blood stays inside the cranium, pooling and forming a clot, or hematoma.
Evacuation of the hematoma is necessary, as it puts pressure on the brain, but it also restarts the bleed. Not all bleeds are arterial. They can be
venous, as well.
Basically, someone being shot in the head doesn't require a ridiculous scenario of them being suspended upside down to protect the clothing. I get the
sarcasm with which it was intended, but I was hoping that someone would explain this. Since they haven't I opted to.
A little anatomy, and understanding that the heat that causes powder burns can also be somewhat cauterizing is all it takes. Also, ask anyone who ever
fired a weapon. The barrel is hot, even after one shot.
