Scorpion anatomy

Most stings from North American scorpions do not need treatment. Children 6 years and younger are more likely to have harmful effects from venomous types of scorpions.

• Clean the area thoroughly with soap and water.
• Place ice (wrapped in a clean cloth) on the site of the sting for 10 minutes and then off for 10 minutes. Repeat this process.
• If the person has problems with blood circulation, decrease the time that the ice is on the area to prevent possible skin damage.
• Keep the affected area still, if possible, to prevent the venom from spreading.
• Loosen clothing and remove rings and other tight jewelry.
• Give the person diphenhydramine (Benadryl and other brands) by mouth if they can swallow.

Investigations

A thorough history is critical for proper diagnosis. In addition, the following tests maybe done:

• Blood and urine tests
• Breathing support, including oxygen, tube through the mouth into the throat, and breathing machine (ventilator)
• Chest x-ray
• ECG
• Fluids through a vein
• Medications to help reverse the effect of the venom
• Symptomatic and supportive care

Prognosis

• Death from scorpion stings rarely occurs in people older than 6 years.
• If symptoms rapidly become worse within the first 2 to 4 hours after the sting, a poor outcome is more likely.
• Symptoms may last several days or longer. Some deaths have occurred as late as weeks after the sting if complications develop.
• Scorpions are nocturnal predatory animals that usually spend the day under rocks, logs, or floors and in crevices.
• DO NOT put your hands or feet in these hiding places.
