The "cut and suck" technique comes from an old (and severely outdated) army medical manual, and while it looks bad-ass on the silver screen, it's the wrong move. You don't want to put ice on the bite or use a tourniquet either. These increase the damage in the locality of the bite by keeping the venom in one spot. And for crying out loud, don't hunt down the snake. The last thing your ER needs is a dead snake scaring the nurses, or worse: a live, venomous snake escaping into the building. All they need to know is what color it was. Some variation of brown, black, or "camo" is a pit viper (rattler, cottonmouth, or copperhead). Red, yellow, and black stripes indicates a coral snake (much more dangerous). According to CDC averages, roughly 7,500 venomous snake bites are reported each year in the U.S. But only about five people a year die from these bites, thanks to modern anti-venom.
