Tourniquet sounds like the best answer. If it a very poisonous snake. by the time you get around to cutting your hand off the vemon is already above the wrist. You would be in a panic so the faster heartbeat would make sure the the vemon spreads quickly. There was a report a bout a year back of some australian who got several bites of a sea snake. He survived, but he was several hours away from help. I think the best one I've heard was of some prat in the US. He was drunk and had a bag full of rattlesnake. To prove how hard (See stupid) he was he put his hand in the bag several times and got bitten everytime. He did survive, but the doctor had to amputate the arm.
