Place ice (wrapped in a washcloth or other suitable covering) on the site of the sting for 10 minutes and then off for 10 minutes. Repeat this process. Immobilize the affected limb. If patient has circulatory problems, decrease the time to prevent possible damage to the skin.
Keep the patient still.
Before Calling Emergency
Determine the following information:
- the patient’s age, weight, and condition
- identification of the insect if possible
- the time stung
Poison Control, or a local emergency number
They will instruct you if it is necessary to take the patient to the hospital. See Poison Control centers for telephone numbers and addresses.
If possible, bring the scorpion to the emergency room for identification.
What to expect at the emergency room
Some or all of the following procedures may be performed:
- Give an antiserum.
- Open and maintain the airway if needed.
- Treat the symptoms.
Death rarely occurs in patients older than 6 years. If symptoms rapidly become worse within the first 2 to 4 hours after the sting, a poor outcome is indicated. Symptoms usually last 24 to 48 hours. Some deaths have occurred as late as 4 days after the sting.
