MOST
IMPORTANT!
Do not delay in getting to a doctor!
Do NOT apply tourniquets, cutting, electric shocks or
application of medicines! These will all do more harm
than good.

In the Field:
If the snake is dead, take it, in a container, with
the patient to the doctor. If the snake has hidden
itself do not waste time looking for it. Remove patient
and onlookers out of the danger area. If you are bitten
by a dangerous snake while alone in the bush, make your
way slowly but steadily to where you can call for help.
Be very calm and reassuring to all. Excited or
hysterical onlookers will increase fear and anxiety in
the patient. Quickly arrange a method of transport to
the doctor.
Seat the patient while removing any constrictions on the
bitten area (ring, watch, tight clothes, etc).
Immobilise the bitten limb with a sling for an arm, a
splint for a leg, or wrap both legs gently together.
Carry the patient on a litter or stretcher.
While getting the patient to the doctor, question
him/her about the circumstances of the bite. This will
help to calm the patient and will give you important
information to pass on the doctor if the patient is
unable to respond by then.
Keep a watch on the patient as you travel to the doctor.
If pain is severe, administer paracetamol - tell the
doctor when you arrive. A sudden drop in blood pressure
may cause the patient to faint. If so, elevate the legs
until s/he recovers. If the patient collapses, s/he
should be placed in the recovery position on his/her
left side with chin up and out to keep airway clear and
prevent breathing in vomit. If paralysis causes the
patient to stop breathing, artificial or mouth-to-mouth
respiration must be maintained until the doctor takes
charge.
Useful questions:
-
Did you see the snake? Describe it.
- Did the snake rear up, spread hood or spit? Describe its actions.
- Did it make any sound?
- Where were you bitten - up a tree, in long grass, wading in water, in
bed?
- At what time were you bitten?
- Have you taken any medications or alcohol, including traditional herbal
medicine, before or after the bite?
Post-treatment
Recovery:
After a patient comes home from hospital, s/he will
require plenty of time to recover. Drinking a lot of
liquid will help the kidneys. If the patient fails to
pass urine regularly or experiences other problems, s/he
should return to the doctor. For a while after recovery,
the patient may have short periods of low blood pressure
and feel exhausted or might even faint. The person
should rest until the feeling passes. If the bite has
caused tissue damage, the resulting wound must be
treated very carefully with regular visits to the doctor
until it has healed properly. Such wounds can easily get
infected and become chronic ulcers, or leave the patient
permanently disabled, so it is worth taking trouble now
instead of having endless trouble later!
Simple Steps to Assist a Patient with Venom in the Eye:
- Wash the eye(s) with plenty of water or any other bland solution (in
emergency, fresh urine will do for eyes only). Then
rinse the mouth, wash the whole face, and any other
exposed body part. Change the patient's clothing if
necessary. Dried venom can easily be transferred to the
eyes.
- The affected eye will be very painful, tear copiously, nose will run and
saliva increases. Blow nose carefully, spit out extra
saliva and be careful to mop eyes softly in an outward
direction.
- Venom in the eye is very painful and alarming, so be calm and firm when
dealing with the patient. Once the eyes have been well
washed, the patient MUST go to a doctor to check for eye
damage. It is not such as acute emergency as actual
snake-bite, but treatment should not be delayed. Shade
the eyes with a hat or dark glasses as glare is very
painful for the patient.
Very
Important:
Do not allow patient to rub eyes!
Wash eyes immediately!
Apply NO medications!
Simple Steps to Living Safely with Snakes:
All snakes are killers of small animals. Snakes are
very important to us because they are a major control of
disease-carrying vermin and crop raiders like rats,
mice, bats, and birds. They are important to the balance
of nature.
Some snakes are venomous enough to endanger our lives if
they bite us, so we need to take some simple precautions
to reduce the chances of an accident. We DO NOT
advise that every snake should be killed.
In the
house: Do not keep livestock in the house,
especially chickens. Snakes can smell them and come in
to hunt. Keep your animals in secure pens at night a
little distance from your house. Store food in
containers to discourage rats and mice - rats come in to
hunt for them. Raise beds above floor level and use a
mosquito net, also a safeguard against centipedes,
scorpions and snakes.
In the compound: Clear heaps of rubbish away from
the house. Do not have piles of firewood, thatching
material, coconut husks or similar near the house. Do
not have shade trees overhanging the house. Keep grass
short or ground clear around your house, and clear
underneath low bushes so that snakes cannot hide close
to the house.
Use a lamp or torch if you have to go outside the house
at night. Wear shoes, especially during the rainy
season, because rising water levels force many snakes
hidden underground to come to the surface. Animals often
give warning of a snake in the area. Be alert to alarm
calls and unusual behaviour. It might save you from a
nasty surprise!
In the bush: Try to watch where your feet are
treading. Long, thick grass or deep leaves may be hiding
a snake. Be careful when moving rocks or fallen wood.
Lift the far side first so that any snake, scorpion or
centipede can escape away from you instead of over your
feet. Do not put your hand down holes without checking
first that no animals are living in it. Better yet, do
not put hands or feet anywhere you cannot see into
first.
Be very careful when clearing bush for planting. Look
first before grasping a handful of grass or bush to cut.
General Advice: Learn exactly which snakes in your area
are venomous enough to be dangerous. Speak to a local
snake expert; write to your National Museum's Reptile
Department or a university library; visit a zoo or good
snake park. It is easy to learn to identify the few
types of dangerous snakes and you will no longer need to
worry about the many other harmless ones. Encourage the
harmless snakes to live around you because they will be
helping to control the vermin. Learn the local names of
snakes commonly found in your area.
Do not attack dangerous snakes unnecessarily! If you are
close enough to kill it, it is close enough to hurt you.
If it is out in the bushes, just leave it alone and warn
your householders to stay away from the area until the
snake has left. If it is trying to come into your living
space, you may be able to scare it away by making a
disturbance from a distance. For example, tap the
branches well ahead of a climbing snake to turn it away,
or throw handfuls of sand ahead of a snake on the
ground. Do not use stones in case you accidentally hurt
the snake, which may then become angry. Make sure nobody
is blocking its escape route. Do not encourage a big,
excited crowd to gather. It is much safer to do the job
quietly and calmly.
Antivenom is the only specific cure for a lethal dose of
snake poison.
Do not wait for a bite to happen before finding out if
your doctor keeps a supply of antivenom. Because it is
quite expensive and needs to be kept refrigerated, many
rural clinics do not stock it. If bites are common in
your area, you may arrange a collection to purchase a
supply of antivenom to store in a centrally located
refrigerator. In this way, one stock may serve a large
area. Contact your Health Department on where to obtain
the correct antivenom for your area.
