3.7 — Snake Bite, and What People Get Wrong

Start with the reassurance, because it is genuine and it changes behaviour.

Most snakes are not venomous. Many bites by venomous snakes deliver little or no venom — a "dry bite" — and with antivenom and supportive care, the great majority of people who reach hospital survive.

And the single largest determinant of outcome is how fast the person reaches a hospital that has antivenom.

Which means: the correct first aid is mostly about getting them there calmly and quickly, and about not doing the things that make it worse.

What not to do

This section comes first, because harmful traditional first aid causes a substantial part of the damage in snakebite, and the practices are widespread.

Do not cut the wound. It causes bleeding, infection and tissue damage, and removes no meaningful amount of venom.

Do not suck the venom out. **By mouth or with a device. **It does not work and it wastes time. Extraction devices have been tested and do not remove a useful quantity.

Do not apply a tight tourniquet. This is the most damaging of the traditional practices. A tight ligature cuts off blood supply, concentrates venom in the limb, and causes tissue death — and people have lost limbs to the tourniquet rather than to the bite.

Do not apply ice.

Do not apply chemicals, herbs, pastes, cow dung, or traditional preparations. Several cause infection and all delay treatment.

Do not give alcohol.

Do not electrically shock the wound.

And do not try to catch or kill the snake. This is how second bites happen, and identification is not required for treatment in most systems — polyvalent antivenom covers the common species.

A photograph from a safe distance is fine if it happens without risk.

What to do

Seven things, in order.

1. Move away from the snake

Calmly. Most second bites happen during attempts to kill or capture it.

2. Reassure them, and keep them still

Fear and movement both speed circulation.

And a large proportion of the immediate symptoms after a bite — racing heart, dizziness, breathlessness — are panic rather than envenoming, which is worth knowing because it makes the reassurance genuinely effective.

Tell them: most bites are not fatal, treatment works, and you are getting them to hospital.

3. Keep the bitten limb still

Immobilise it as you would a fracture — a splint if available, or a sling for an arm.

Position: at or slightly below the level of the heart.

And the person should not walk if it can be avoided. Carry them, or bring transport to them.

4. Remove anything constricting

Rings, watches, bangles, tight clothing, footwear — immediately, before swelling starts.

Swelling can be considerable and jewellery becomes a tourniquet.

5. Call and go

112, or 108 for an ambulance in most Indian states.

And find out in advance which nearby hospital stocks antivenom, if you live where snakebite is a real risk. Not every hospital does, and arriving at the wrong one costs the time that matters most.

6. Mark the swelling

Genuinely useful and almost nobody does it.

Draw a line at the edge of the swelling with a pen and write the time. Repeat every fifteen to thirty minutes.

This gives the treating doctor a direct record of how fast envenoming is progressing, which is clinically valuable.

7. Watch breathing

Some venoms — particularly from cobras and kraits in the Indian context — affect the nerves and can progressively paralyse the muscles of breathing.

Early signs: drooping eyelids, difficulty swallowing, slurred speech, blurred vision.

If breathing fails, be ready to give rescue breaths and CPR (3.2). A person with respiratory paralysis whose breathing is supported can survive until antivenom works.

The pressure immobilisation question

Worth addressing because guidance differs and readers will encounter both.

Pressure immobilisation bandaging — firmly bandaging the whole limb and splinting it — is recommended in Australia, where the dangerous snakes are predominantly neurotoxic.

In India, the standard national guidance has generally not recommended it for general use, because it is frequently done wrongly, because many Indian bites cause local tissue damage that a tight bandage worsens, and because it can delay transport.

Practical position for a non-medical reader in India: do not attempt pressure immobilisation.

Immobilise the limb, keep it at or below heart level, keep the person calm and still, and get to hospital. That is the guidance, it is simpler, and it is safer to do incorrectly.

What happens at hospital

Because knowing it reduces fear considerably.

They will observe. Many bites are dry and require nothing but monitoring, and observation for a period is standard.

They will test. A simple whole-blood clotting test is used in many places to detect venom effects on clotting.

They will give antivenom if indicated. It works, and it works better the earlier it is given.

And they will support breathing if needed, which is why respiratory paralysis is survivable in hospital and frequently is not outside one.

Prevention, which is most of it

Because the highest-value section in this chapter is the one about not being bitten.

Most bites are on the foot or lower leg, at night, in rural areas, during agricultural work or while walking.

Wear shoes. **Closed footwear, particularly at night and in fields. This single measure prevents a large share of bites.

Use a light at night. A torch when walking outdoors after dark.

Do not sleep on the floor in areas where kraits are present. **A substantial number of krait bites happen to people sleeping on the ground, and the bite is often almost painless — people wake with abdominal pain and progressive weakness. A raised bed and a tucked-in mosquito net are genuinely protective.

Do not put hands into holes, woodpiles, grain stores or under rocks without looking.

Keep the area around the house clear of rubbish and rodent food, because snakes follow rodents.

And leave snakes alone. Almost all bites happen during attempts to handle, kill or move one.

What to do with this page

Do not cut, suck, tourniquet, ice, or apply anything. The traditional first aid is the danger.

Keep still, immobilise the limb at or below heart level, remove rings and watches, and go.

Mark the swelling with a pen and the time.

Watch for drooping eyelids and difficulty swallowing, and be ready to support breathing.

And wear shoes at night and do not sleep on the floor. Prevention is the highest-value part of this chapter by a wide margin.
