What happens if a snake bites you?
Bites by venomous snakes result in a wide range of effects. They range from simple puncture wounds to life-threatening illness and death. The findings following a venomous snakebite can be misleading. A victim can have no initial significant symptoms, and then suddenly develop breathing difficulty and go into shock.
How does snake venom affect the nervous system?
Nervous system effects: The effect on the nervous system can be experienced locally close to the bite area or affect the nervous system directly. Venom from elapids and sea snakes can affect the nervous system directly. Cobra ( Naja and other genera) and mamba ( Dendroaspis) venom can act particularly quickly by stopping the breathing muscles, resulting in death without treatment. Initially, victims may have vision problems, speaking and breathing trouble, and numbness close to or distant to the bite site.

Pit viper bites can cause a leakage of blood cells out of the blood vessels, even on parts of the body away from the bite site.
How do poisonous snakes inject venom?
Poisonous snakes inject venom using modified salivary glands. During envenomation (the bite that injects venom or poison), the venom passes from the venom gland through a duct into the snake's fangs, and finally into its prey. Not all bites lead to envenomation.

Treatment was immobilization of the extremity with a splint and the application of a firm crepe bandage to the length of the extremity. This intervention resulted in low levels of circulating venom relative to controls. Neither application of a splint alone nor of the pressure bandage alone delayed systemic detection of venom.
How does a venom extractor work?
Venom extractors are suction devices that are proposed to work by applying suction to the site of a snakebite. These devices are marketed by companies that target outdoorsmen. The purported design is supposed to apply negative pressure over fang marks to induce venom extraction. Venom extractors can still be purchased through major retailors online and instores, despite several studies proving their ineffectiveness [12,13]. A human study by Alberts et al., modeling western diamondback envenomation, demonstrated only a mean 2.0% decrease in total body venom load and an average 0.04% decrease of mock venom at the site of envenomation after 15 min of extraction. A porcine model with Crotalus atroxvenom, by Bush et al., demonstrated concerns for injury by the extraction device and no benefit in decreasing local tissue injury after 30 min of extraction [13]. Alberts et al. suggested that the extractors could have collapsed the subcutaneous tissue, and pulled fluid from superficial capillaries that contain minimal venom load [12]. Our opinion is that any significant change in clinical outcomes is doubtful with such minute changes in venom load.

Pressure immobilization bandage consisting of an ace bandage wrapped beginning at the site of bite and wrapping the entire extremity, followed by a splint, in a porcine model of eastern coral snake envenomation. From [24], used with permission of the publisher.
What system transports venom from the envenomation site to the systemic circulation?
The lymphatic system transports venom from the envenomation site to systemic circulation. Application of a tourniquet will sequester venom locally, potentially leading to increased local tissue destruction when the venom is from those snakes that cause local tissue damage. Additionally, tourniquets can impede venous blood flow and arterial blood flow, leading to limb ischemia, gangrene, and potentially amputation.
Is antivenom available for snake bites?
Intravenous antivenom is the definitive treatment for venomous snakebites but is expensive, often in short supply, and not available in many rural and poorly developed regions [1,2]. Timely transportation to facilities that stock and administer antivenom may not be available in areas with poorly developed emergency medical services. These factors have led to consideration of measures to delay onset of toxicity or alternatives to antivenom therapy.
Can pit vipers be suctioned?
Current guidelines from the Wilderness Medical Society and American Heart Association do not support the use of mechanical suction for pit viper envenomations [7,17]. An initial search of the medical literature did not yield results addressing the use of suction for other types of snake envenomations, such as elapids. Despite the evidence against use of mechanical suction, there are many unreliable sources available to the public. One study found that of 48 websites reviewed for accuracy of information regarding pre-hospital care of snakebites, 26 (54.1%) contained inappropriate recommendations [18]. Education for clinicians and the public regarding safe and effective pre-hospital care is imperative in preventing further harm to snakebite victims.
Can electric shock be used for snake bites?
Electric shock has been advocated as a treatment for ve nomous snakebites, though there is no scientific rationale for use of electric shock and no data to support its use, other than case reports. Its use was advocated in a letter to the editor of Lancet in 1986, in which it was claimed that the experience in the jungles of Ecuador of applying a high-voltage, low-amperage electric current to the grounded extremity prevented both local and systemic toxicity [19]. Electric shocks have been administered from outboard motors and stun guns. It was ineffective in a controlled study of mice injected with northern Pacific rattlesnake (Crotalus virldis oreganus) venom at varying doses [20]. The shocks neither reduced toxicity in rats injected with sublethal doses of fer-de-lance (Bothrops atrox) venom nor lethality in mice injected with lethal doses [21]. In a case report, administration of electric shock resulted in coma and incontinence [22]. The United States Food and Drug Administration has banned the use of these devices, which were previously sold to the public for the treatment of snakebites and spider bites (United States of America vs. CONO).
How to treat a snake bite?
