First Aid
|
Description: First aid for scorpion stings (in areas where no potentially dangerous species may be found)
|
Details
1. Reassure the victim. Despite sometimes intense local pain, usually lasting less than one hour, these scorpions are not able to cause major of lethal envenoming and most stings will settle rapidly. 2. Do not apply a bandage or tourniquet, or cut, suck or incise the wound or apply electric shock. Neither the application of local heat or cold are proven as effective. 3. If the victim develops general symptoms or the pain remains severe after one hour, seek medical advice.

Treatment
|
Treatment Summary
Stings by these scorpions are likely to cause only short lived local effects, such as pain, without systemic effects. Treatment is therefore reassurance and symptomatic, with analgesia only for severe and persistent pain, as short lived pain will likely resolve before analgesics can take effect. Update tetanus immune status. Be more cautious in young children, observing for several hours post-sting. No antivenom is available, or is required.
|
Key Diagnostic Features
Not well defined. Most likely limited to local pain ± local swelling, without significant systemic effects. See detailed clinical summary for more specific detail, if known.
|
General Approach to Management
Most cases will be minor & not require admission.
|
Antivenom Therapy
No antivenom available
