Australian Scorpions – bizarrely are less dangerous then those found elsewhere in the world. Current evidence would suggest they usually cause temporary pain and minor systemic symptoms only. Interestingly the smaller the scorpion the more painful the bite is.
- Not life threatening
Typical symptoms include:
- Pain at sting site can be severe and lasts up to 24 hours but usually has resolved by 6-12 hours.
- Other local features include erythema, mild swelling and numbness.
- Systemic symptoms can occur in 10% of patients and are listed to nausea, headache and malaise
- 1. Analgesia – Simple analgesia such as paracetamol and ibuprofen along with ice are good for initial first aid. If this is inadequate then opiates such as morphine 0.1 mg/kg has been used to good effect.
- 2. PBI dressings are not required
- Not required
- Many spiders, bees, wasps, ants and even centipedes in Australia can cause a similar presentation. Of note it would be prudent not to miss a Funnel-web spider envenomation characterised by a painful bite, sweating, agitation, pilorection, cardiovascular abnormalities and neurological changes
- Not available
- As a general rule patients do not usually require a hospital admission unless pain is an issue.
