What happens when a snake bites you? Signs and Symptoms of Snakebite, Diagnosis, and Treatment.
What happens when a snake bites you: A snakebite is an injury brought on by a snake’s bite, particularly one that is poisonous. Two puncture wounds from the animal’s teeth are a typical indication of a poisonous snake bite.
Venom injection from a bite may take place sometimes. [This may cause the region to become red, swollen, and extremely painful, with symptoms taking up to an hour to manifest. Sweating, nausea, hazy vision,
and tingling in the limbs are possible side effects. The hands, arms, or legs seem to get bit the most. The signs of fear after a bite includes dizziness and a rapid heartbeat.

The venom may result in breathing difficulties, renal failure, a severe allergic response, haemorrhage, or tissue death around the bite. Bites can lead to the amputation of a limb, other chronic conditions, or even death.
The species of snake, the part of the body that was bitten, the amount of snake venom injected, the overall health of the person who was bitten, and whether or not anti-venom serum was promptly provided by a physician all affect the result.
Due to their smaller stature than adults, children frequently have problems that are more severe. Anaphylaxis and other allergic responses to snake venom can further complicate treatments, need more care, and in rare circumstances even result in fatalities.
Signs and symptoms of Snake bite
An overpowering panic is the most typical initial symptom of all snake bites. This anxiety can lead to additional symptoms such as nausea and vomiting, diarrhoea, vertigo, fainting, tachycardia, and cold, clammy skin. Depending on the kind of snake bitten, there may be a range of different signs and symptoms.
Even non-venomous snakebites and dry snakebites can result in serious harm. The saliva from the snake might cause the bite to get infected. The fangs can occasionally contain dangerous microorganisms like Clostridium tetani, necessitating a recent tetanus vaccination.

First aid for Snake bite
Because various snakes have different forms of venom, there are distinct first aid guidelines for snakebites. Some have little local effects but potentially fatal systemic consequences, in which case pressure immobilisation is preferable to keeping the venom in the bite area under control.
Some venoms cause localised tissue damage around the site of the bite, and immobilisation may exacerbate this damage while also reducing the overall area impacted. Whether this trade-off is preferable is still up for debate. First aid procedures differ since snakes vary from one country to the other.
The American Medical Association and American Red Cross are two organisations that advise cleansing the bitten with soap and water. Cleaning the wound is discouraged in Australian advice for snake bite treatment.
Snake bite identification kits can be used in conjunction with traces of venom left on the victim’s skin or bandages to determine the type of snake that bit them. This expedites choose which antivenom to use in the emergency department.
Pressure Mobilization
Clinical evidence for pressure immobilisation with an elastic bandage is inadequate as of 2008. It is advised for snakebites that happened in Australia (due to elapids which are neurotoxic).
It is not advised for non-neurotoxic snake bites such as those prevalent in North America and other parts of the world. In all situations when the type of snake is unclear, the British military advocates pressure immobilisation.
The goal of pressure immobilisation is to keep venom inside a bitten limb and keep it from spreading to crucial organs via the lymphatic system. This treatment consists of two parts: pressure to impede lymphatic drainage and immobilisation of the bitten limb to hinder skeletal muscle pumping.
Antivenom
Prior to the development of antivenom, snake bites were virtually always fatal. Despite significant breakthroughs in emergency medicine, antivenom is frequently the sole effective treatment for envenomation.
In 1895, French surgeon Albert Calmette produced the first antivenom for the treatment of Indian cobra stings. Antivenom is created by injecting a little quantity of venom into an animal (typically a horse or sheep) in order to stimulate the immune system. The antibodies produced are then extracted from the animal’s blood.
Antivenom is given intravenously into the patient and acts by binding to and neutralising venom enzymes. It cannot reverse venom damage, thus antivenom treatment should be undertaken as soon as feasible.
Current antivenoms are often polyvalent, which means they are effective against the venom of a wide range of snake species. Pharmaceutical manufacturers that manufacture antivenom focus their medications against species local to a certain region.
Although some people may experience major adverse responses to antivenom, such as anaphylaxis, this is typically treated in an emergency setting, and so the benefit exceeds the possible dangers of not taking antivenom. Adrenaline (epinephrine) used to avoid antivenom-induced adverse responses may be justified in circumstances when they occur often. Antihistamines appear to have little value in terms of avoiding unpleasant responses.

Types of Snake bite
Dry bites
A dry bite occurs when a snake bites but no venom is released. Dry bites are unpleasant and might cause swelling and redness in the region where the snake bit victim.
After seeing a doctor, you should not require any more treatment, such as antivenoms (which are medicines that act against the effects of venom). Because many snake bites in Australia do not result in venom entering your body (known as envenomation), they can be treated without the use of antivenom.
Venomous bites
Venomous bites occur when a snake bites you and injects venom into the wound. Snake venom includes chemicals intended to paralyze, numb, or kill other creatures.
A poisonous bite might cause the following symptoms:
intense discomfort surrounding the bite – this may take some time to manifest
swelling, bruising or bleeding from the bite
bite marks on the skin — these might be obvious puncture wounds or almost invisible small scratches
Once venom starts to spread within the body, you may develop symptoms including:
- headache, confusion, or dizziness
- blurred vision
- irregular heartbeat
- muscle weakness or paralysis (being unable to move)
- breathing difficulties
- nausea (feeling sick), vomiting (being sick), or abdominal pain

How long does it take for symptoms of snake bite?
Swelling might appear within 15 minutes and reach a peak in 2-3 days. It can last up to three weeks. Swelling develops quickly from the biting site and may encompass the entire leg and ankle boot. Regional lymphadenopathy is possible.

How can I prevent snake bites?
- The majority of snake bites occur when people attempt to kill or catch them.
- If you come across a snake, don’t be alarmed.
- Back up to a safe distance and let it go. When snakes are agitated, they frequently attempt to flee.
- Additional precautions you may take to avoid snake bites include being cautious of where you walk or lay your hands when in the wilderness, especially at night when snakes are more active.
- If you’re out in the forests at night, carry a torch.
- When strolling in the bush, make a noise and stamp your feet to alert any snakes to your presence.
- Wear heavy clothes, such as trousers and footwear, to protect yourself against bites.
Diagnostic tests and tools for Snakebite

There is now just one commercial diagnostic test available to confirm the kind of snake venom found in the body of an envenomed patient. This test employs antibodies to identify distinct kinds of venom generated by various snake species.
Snake bite treatment protocols
Antivenom treatments
When taken early and in an acceptable therapeutic dose, antivenoms remain the only specialized therapy that can possibly prevent or reverse the majority of the symptoms of snakebite envenoming. They are on the World Health Organization’s Model List of Essential Medicines.
Early access to safe, inexpensive, and effective antivenoms is crucial for reducing morbidity and death, and enhancing access is a key component of a new WHO approach to minimize snakebite envenoming.
Additional therapy to treat envenoming
To properly treat snakebite victims, further medical measures such as the administration of various medications, artificial respiration, renal dialysis, wound care, reconstructive surgery, and prosthesis, as well as complete rehabilitation services, are required in addition to antivenom. Anticholinesterases are a family of medications that can help restore neuromuscular function after being bitten by some species of neurotoxic venomous snakes.
Many medications are also being investigated for their potential to work as anti-necrotic agents, minimizing the local tissue damage that can result in severe impairment and even amputation following snake bites.
