Snake Bites – Everything you need to know in a nutshell 

Snake bites are a life-threatening injury, and must be treated with utmost seriousness. If you or anyone you know gets bitten by a snake, you must call for an ambulance immediately and seek emergency medical services[14] at the nearest hospital. Do not try to cut the wound and suck out the poison or apply a tourniquet. Instead, remove all tight clothing and keep the patient as calm as possible until help arrives. Snake bites are of 2 types – venomous and non-venomous. Although non-venomous snake bites are less dangerous, always err on the side of caution and take the patient to the hospital immediately. At the hospital, the doctors will treat the patient on an emergency basis and administer antivenin (if required) to save the patient’s life. Prevention is better than cure when it comes to snake bites, so always be very careful when you are outdoors.

What is a Snake Bite?

A snake bite is a wound caused by a snake, usually by sinking its fangs into the victim’s flesh. Snake bites are much more common and life-threatening than most people realise. The WHO estimates the around 5.4 million people all over the world are bitten by snakes every year. Of these, around 1.8 to 2.7 million people are bitten by venomous snakes.

What’s the difference between Venomous and Non-venomous snake bites? 

When a snake bites you, it may inject poison into your veins. If it does so, it is a venomous snake. Once injected into the bloodstream, the toxins can spread throughout the body and affect key organs like the heart and the brain, causing partial or complete paralysis, and eventual death. The purpose of the venomous injection is to prevent the snake’s prey from thrashing around or moving away. Having said that, non-venomous snake bites can be as dangerous and should not be treated lightly.

Which are the most dangerous snakes in India? 

In India, we have about 300 species of snakes, of which only about 15 are venomous enough to kill a human being. Four species of snakes are responsible for a majority of snake bites in India:

  1. The Indian Cobra
  2. The Common Krait
  3. Russel’s Viper
  4. Saw-scaled Viper.

If you or someone you know gets bitten by a snake, it would be good to make note of the approximate length, girth and colour of the snake. This could help the rescue team or first aid team identify the correct protocol for treatment. In case there is any doubt about whether the snake is venomous or non-venomous, it is usually safe to treat it as a venomous snake bite.

What is the correct First Aid for Snake Bites? 

Snake bites are life-threatening and should be treated with urgency. First and foremost, you need to call an ambulance. While waiting for medical assistance, you can take the following steps:

  1. Maintain distance from the snake. Avoid a second bite at all costs.
  2. Remain calm and try to slow your breathing. Panic will increase your blood circulation and cause the toxins to spread more quickly throughout the body.
  3. Remove any jewellery or tight clothing. This will help avoid swelling of the bitten area.
  4. If possible, take a photograph of the snake that bit you and make note of the time at which the bite happened.

Here are some outdated first aid techniques for snake bites, which are no longer prescribed by doctors and should be avoided:

What are the symptoms of a Snake Bite?

The symptoms of the snake bite are based on the type of snake that bit you.

A non-venomous snake bite typically causes:

Venomous snake bites cause:

In case you have an allergic reaction to the snake venom, the body could go into anaphylactic shock. The symptoms of anaphylactic shock are:

Anaphylactic shock is a very serious, life-threatening complication of snake bites. It is crucial to get emergency medical help as quickly as possible.

Who is at Risk? 

 Snake bites are more common in rural areas and forested areas. In cities, snake bites are rare, and usually only occur in parks, gardens or along waterbodies. Water-logged areas are breeding grounds for snakes, and residents who live in areas prone to flooding are at a higher risk of snake bites. In areas where manual scavenging is still common, the sanitary workers are at very high risk of encountering snake bites in the dark underground pipelines.

In rural areas, agricultural workers are primarily at risk of getting bitten by snakes while working in the fields. In small towns and villages where open defecation is still practised (despite schemes and subsidies from the government to construct toilets), snake bites are a common danger to people who go out into the fields to relieve themselves.

Travellers, nature explorers and trekking enthusiasts also have a significant risk of snake bites on their expeditions. Zoologists, herpetologists and zoo staff are also vulnerable to snake bites.

The following groups of people are particularly vulnerable, and have higher chances of mortality once bitten by a snake:

How are snake bites diagnosed? 

Once the snakebite victim has been taken to the nearest emergency hospital[16] or clinic, the doctor will check the wound and diagnose the snakebite. Blood tests will be performed to check if there is venom in the body, and if so identify the type of snake venom. This step is crucial, as anti-venom formulations are highly specific to the species of snake. At this stage, it is important to give the doctor all the details you remember about the snake that bit the victim, as this can help them identify the venom correctly.

What is the Treatment for snakebites? 

Non-venomous snake bites are not life-threatening. In most cases of non-venomous snake bites, the doctor will simply clean the wound thoroughly, and give the patient a tetanus shot.

Venomous snake bites are treated with anti-venom. Anti-venom is a type of anti-body therapy. A serum of concentrated anti-bodies to counteract the venom’s toxic effects are injected into the patient’s blood stream. Anti-venom can prevent damage to the body, but it cannot repair damage that has already occurred due to the toxin. It is for this reason that identifying the venom and administering the anti-venom as fast as possible is so crucial. Depending on the strength and amount of venom injected by the snake, the patient may need multiple doses of antivenin to successfully neutralise all the poison.

Some patients experience side-effects of anti-venom treatment such as:

How is Anti-venom made? 

Anti-venom is manufactured by injecting controlled amounts of the venom into animals like horses. Small doses of the venom are injected over time to gradually build up the animal immunity to the venom. The animal then begins producing antibodies to the venom. The blood from these animals is harvested, and the plasma is concentrated to isolate the anti-venom.

What are the long-term consequences of a snake bite?

The long-term outlook for a snake bite victim is highly variable.

For non-venomous snake bites the outlook is very good, provided the wound is cleaned and treated properly immediately. Shallow bites heal very quickly and usually have no long-term effects. The patient may simply be left with a scar to remember the incident by. Deeper bites, depending on where they are located, can cause serious damage to nerves and blood vessels, which take time to heal. Do not ignore a snake bite just because it is non-venomous, as the wound can get infected and cause complications.

Patients with venomous snake bites can avoid fatalities by seeking prompt treatment and ensuring the correct antivenin is administered to the patient. The patient may be left with certain complications caused by the venom in the time taken to get treatment. The patient may be left with discoloured skin, blisters and tissue loss which may never fully recover to its original condition. In rural and forested areas, where immediate medical assistance is hard to come by, snake bites can be fatal or result in permanent damage to limbs.

How can Snake Bites be prevented? 

Prevention is better than cure – Especially with snake bites!
