Snakebite First Aid in Nigeria

One of Nigeria's most preventable deaths — immediate action saves lives

Snakebite kills an estimated 10,000–15,000 Nigerians per year and permanently disables many more. Nigeria's most dangerous snakes include the carpet viper (Echis carinatus — responsible for most deaths), the forest cobra, the black-necked spitting cobra, the gaboon viper, and the green mamba. Most bites occur in rural areas during farming or at night. Many victims die from delayed treatment, harmful traditional remedies, and lack of antivenom. Correct first aid and rapid hospital transfer are life-saving.

Signs and Symptoms

✓ Carpet viper (most common deadly species): Local swelling and pain at bite site. Spontaneous bleeding from gums, nose, wounds — coagulopathy (blood doesn't clot). Haematuria (blood in urine). Death from internal haemorrhage.
✓ Cobra: Local necrosis and tissue death. Ptosis (drooping eyelid), double vision, difficulty swallowing — neurotoxic features.
✓ Gaboon viper: Massive local swelling; haemotoxic features; death from shock and bleeding.
✓ Spitting cobra: Eye pain, tearing, and blindness from venom in the eyes — no systemic effects from spitting alone.
✓ NOT all bites from venomous snakes envenomate — 'dry bites' (no venom injected) occur in 30–50% of cases.

Risk Factors

When to Seek Help

ANY snakebiteGo to hospital immediately — even if symptoms are mild or absent. Envenomation may be delayed. Every snakebite needs assessment.
ANY bleeding from unusual sites after a biteCarpet viper coagulopathy — a medical emergency. Blood from gums, nose, wound site, or urine after a bite = go to the nearest hospital immediately.
Drooping eyelid or difficulty swallowing after a biteNeurotoxic envenomation — requires antivenom urgently.
Eye contamination from spitting cobraIrrigate the eye with water for 15–20 minutes. Then go to hospital for eye assessment.

Tests & Diagnosis

🧪 20-minute whole blood clotting test (20WBCT)
A simple, equipment-free test done at the bedside: place 2 ml of venous blood in a clean glass tube, leave undisturbed for 20 minutes. If blood does not clot (or clot is absent or fragile) = haemotoxic envenomation from carpet viper. Directs antivenom use. Can be done at any level of health facility.
🧪 Full blood count
Haemoglobin and platelet count assess severity of haemotoxic envenomation.
🧪 Coagulation screen (PT, APTT, fibrinogen)
Confirms disseminated intravascular coagulation (DIC) from carpet viper.
🧪 Renal function
Snakebite causes AKI — creatinine and eGFR essential.
🧪 Urine dipstick
Blood in urine (haematuria) from haemotoxic viper bite.

Treatment Options

1
DO: Immobilise the bitten limb
Keep the bite below heart level. Immobilise like a fracture — the limb should not move. This reduces venom absorption. A splint or sling is ideal.
2
DO: Remove watches, rings, and tight clothing near the bite
Swelling can be rapid and severe — jewellery causes constriction.
3
DO: Travel to hospital as fast as possible
Keep the patient still and calm (movement increases venom absorption). Carry them rather than letting them walk.
4
DO: If a spitting cobra has sprayed venom into eyes
Flush eyes immediately with large amounts of clean water for 15–20 minutes. This prevents permanent eye damage.
5
DO NOT: Cut and suck the wound
Dangerous — introduces infection, causes tissue damage, and does not remove significant venom.
6
DO NOT: Apply tourniquet
Causes tissue death from ischaemia — significantly worsens outcomes and leads to limb amputation. This advice is widely practiced in Nigeria and is wrong.
7
DO NOT: Apply traditional remedies (herbs, black stone)
Black stones, herbs, and cutting do not neutralise venom. They waste time and worsen outcomes.
8
DO NOT: Drink alcohol or give NSAIDs
Both worsen bleeding from haemotoxic venom.
9
Antivenom
The definitive treatment. African Polyvalent Snake Antivenom (EchiTab and others) covers Nigerian carpet vipers and cobras. Give IV in hospital as soon as haemotoxic or neurotoxic envenomation is confirmed. Repeat doses if bleeding continues. Available at government hospitals and some state health facilities. Stock levels are variable — advocate for stocking in your local hospital.

Frequently Asked Questions

How do I know if a snakebite was venomous?
You cannot tell immediately by the appearance of the bite or the snake. The 20-minute whole blood clotting test can confirm carpet viper envenomation at any health facility without laboratory equipment. ALL snakebites should be taken to hospital for assessment — do not wait for symptoms.
Is a tourniquet recommended for snakebite?
No — this is one of the most damaging snakebite myths in Nigeria. Tourniquets stop blood flow to the limb, causing severe tissue death (ischaemia) and greatly increasing the chance of amputation. They do not prevent systemic envenomation. Do not apply a tourniquet for any snakebite.
Where can I get antivenom in Nigeria?
Government hospitals (teaching hospitals and general hospitals) are supposed to stock antivenom. In practice, availability is inconsistent. Teaching hospitals in major cities are the most reliable. The Federal Ministry of Health has targeted rural antivenom distribution programmes. If antivenom is unavailable locally, advocate for patient transfer to a better-stocked facility.
Which snake is responsible for most snakebite deaths in Nigeria?
The carpet viper (Echis carinatus) is responsible for more snakebite deaths and disabilities in sub-Saharan Africa — and particularly Nigeria — than any other snake. Its venom causes a devastating coagulopathy (inability to clot blood). It is a small, inconspicuous snake found in all ecological zones of Nigeria.
What is the black stone treatment for snakebite?
The black stone (or snakestone) is a hard, porous object (often carved bone or activated charcoal) pressed against the bite wound, claimed to absorb venom. There is no scientific evidence it extracts venom from tissue, and its application wastes critical time that should be used for hospital transfer and antivenom. It should not replace medical treatment.
