Snake bite

Snake bites in Australia most commonly happen in the warmer months when snakes are more active. Australia has some of the world’s deadliest snakes. They mainly live in rural and remote areas and are found out and about on farms looking for water or food.

Snake bites often occur if a snake needs to be defensive. If bitten by a snake, it is important to recognise the type of snake as different types of snakes bite differently, release venom differently and have venom which will affect the body differently. Common sites to be bitten are hands, arms, feet and ankles. Medical assistance is urgent after a snake bite.

Symptoms of snake bite may include:

  • pain
  • local effects – swelling or bruising around the bite
  • widespread effects – including abdominal pain, nausea, vomiting, blurred vision, slurred speech, muscle weakness and respiratory distress.

First aid for snake bite aims to stop the venom moving around the body. Depending on the volume of venom injected, research indicates very little venom reaches the circulation if pressure is applied over the site and the limb is immobilised. If the snake is angry and stirred up, it may release more venom when it strikes.

What you should do:

  • Call an ambulance
  • DO NOT wash the bite or attempt to catch/kill the snake.
  • Do not apply a tourniquet or remove clothing.
  • Apply pressure to bite area.
  • If a limb is bitten, bandage the area of the bite firmly with a broad (10-15cm wide) pressure bandage (as firmly as you would for a sprained ankle).
  • Apply another broad bandage starting at toes or fingers and bandage up limb as far as possible.
  • Crepe and compression bandages are ideal – but use anything available if no bandages are available. E.g., tear up a shirt, towel or sheet.
  • Splint limb to prevent any muscle, limb or joint movement.
  • Mark the bandaged area over the snake bite with a X. This will allow the doctor to quickly locate the bite without removing the bandage.
  • If the bite is to the trunk or torso still apply a firm bandage.
  • If the bite cannot be bandaged then apply and keep constant firm pressure.
  • DO NOT walk! Keep still, remain calm and try not to panic. Movement and panicking will cause the venom to circulate faster.
  • Activate your emergency plan to get help and medical assistance urgently
  • If the snake bite victim collapses or stops breathing, apply CPR (cardiopulmonary resuscitation) until medical help arrives.

Fast facts:

  • Avoid being bitten by a snake.
  • If bitten – don’t panic and don’t try to catch the snake.
  • Follow basic first aid for snake bite, even if you’re not sure if the snake was venomous.
  • Don’t wash the skin, venom traces may help identify the snake.
  • Send for help by calling triple (000) immediately.
  • Remain still and calm until help arrives.
  • Do not raise the limb.
