T63.411 Toxic effect of venom of centipedes and venomous millipedes, accidental (unintentional)

Name of the Condition

• Toxic effect of venom of centipedes and venomous millipedes, accidental (unintentional)

Summary

This condition describes adverse health effects resulting from accidental exposure to the venom of centipedes or venomous millipedes. The effects can range from localized reactions to systemic toxicity, depending on the species and exposure type.

Causes

Exposure to centipede or millipede venom occurs when these arthropods inject venom through bites or stings. Venom contains toxins that can trigger inflammatory or systemic responses in the body.

Risk Factors

• Outdoor activities in regions with centipedes or venomous millipedes.
• Disturbing or handling these arthropods.
• Lack of protective gear (e.g., gloves, footwear) in high-risk environments.
• Occupational exposure (e.g., landscaping, pest control).

Symptoms

• Localized pain, swelling, or redness at the contact site.
• Itching, rash, or blistering.
• Systemic effects like nausea, dizziness, or respiratory distress (with severe envenomation).
• Neurological symptoms (e.g., muscle spasms, numbness) in some cases.

Diagnosis

Clinical evaluation of symptoms and exposure history. Identification of bite/sting marks or arthropod contact. Laboratory tests (e.g., blood work) may assess systemic effects.

Treatment Options

• Immediate wound care (cleaning, elevation).
• Pain management (e.g., analgesics).
• Antihistamines or corticosteroids for allergic reactions.
• Tetanus prophylaxis if indicated.
• Severe cases may require antivenom or hospitalization.

Prognosis and Follow-Up

Most cases resolve with supportive care. Severe reactions may require extended monitoring. Follow-up depends on symptom severity and response to treatment.

Complications

• Allergic reactions or anaphylaxis.
• Secondary infections at the bite site.
• Prolonged pain or tissue damage in severe cases.

Lifestyle & Prevention

• Wear protective clothing (e.g., long sleeves, closed shoes) in infested areas.
• Avoid handling centipedes or millipedes.
• Use pest control measures to reduce habitat near living spaces.

When to Seek Professional Help

Seek medical attention if symptoms worsen, systemic effects develop, or the bite site shows signs of infection.
