Well, Jeff, according to what Findley Russell told me, and what I've read, you are partially right. Adult snakes can and do regulate the amount of venom injected. However, the vast majority of poisonous snake bites are NOT envenomations. They don't usually even waste enough to kill a mouse or rabbit. If you DO get a massive envenomation, it is usually because you have hold of the snake (snake handlers), or you have a fang or fangs stuck in your boot, or some other aggravating factor making the snake afraid.
Baby snakes are too young to have learned this control, and thus more often envenomate humans. They are the exception to the rule.
Actually, rattlesnake collecting is fun. I used to do it in the '60's and '70's when I lived in So. CA. The thing you had to be most careful about was traumatizing the snake; we used large pickle jars with wide mouths, and would just guide the snake into them with handling sticks. We did NOT pick the snakes up. This would send them into shock and they would not eat for months.
Billpaxton: I read up on the electric shock treatment of snake bites, and this goes back to one 'researcher' who used a sparkplug from an outboard motor in a very rural area to treat people! There have been studies with animals injected with venom and then shocked. No benefit was found. The 'researcher' was probably successful, as most of the patients, remember, were NOT envenomated. Thus, an herbal treatment would have been equally effective.
TOMBSTONE; there is evidence that nothing you can do will get a significant amount of venom out once it is injected. There is a device called a Sawyer venom extractor (as mentioned above by Jebediah) available from the Univ. of AZ, but its' proponents are few, and the device doesn't remove much venom under the most ideal conditions. Cutting and sucking is a big no no.
Jebediah also mentioned a new antivenom (the word used to be antivenin, it is still spelled both ways and means the same thing); I perused the U of AZ site at length and could not find out anything about it. I would appreciate a reference.
Findley Russell told me 15 years or so ago that he had developed a human diploid antivenom (Polyvalent Crotaloid; good for all pit vipers in the USA) for Wyeth, but they wouldn't put it on the market, due to the high cost and low profit. This would make the antivenom non dangerous, as it wouldn't cause anaphylaxis, as the old horse serum often does. I would like to think that they finally got their act together and got a product on the market. The rabies vaccine was made human diploid about 20 or so years ago, and the shots are NOT PAINFUL.
Hope this helps,
