Snake Bites

.. ged. The danger is that they could develop an adverse reaction or even a potentially fatal allergic condition called anaphylactic shock. The Food and Drug Administration regulates antivenins as part of its oversight of biological products. The agency requires certain criteria to be met before these materials are sold, including standards for purification, packaging and potency. FDA also regulates antivenin labeling, ensuring that data on potential side effects and other pertinent information are available. The agency also periodically inspects antivenin production facilities to ensure compliance with regulations.(For Goodness Snakes) Many snakebites are caused by nonvenomous (nonpoisonous) snakes and do not require treatment beyond cleaning the wound.

Bites inflicted by venomous snakes require immediate first-aid measures. The victim should be taken as soon as possible to the nearest emergency medical facility. In the interim, the first-aid provider should not cut the area around the bite, attempt to suck out the venom, or apply ice to the wound. The focus of first aid should be to prevent the venom from spreading rapidly through the individual’s bloodstream. The victim should be kept quiet to avoid stimulating circulation of the venom.

It also aids in keeping the venom from spreading by applying a negative pressure against the tissue where the venom was initially deposited and creates a gradient which favors the movement of venom toward the external collection cup. 5.
