Scorpion sting management

Most scorpion stings cause only local pain and can be managed symptomatically. Severe envenomation is uncommon but can progress quickly, especially in children, and needs urgent hospital care.

1) First aid (immediate)

  1. Move away from the scorpion, reassure the patient, keep them calm.
  2. Wash sting site with soap and water.
  3. Apply a cold pack intermittently (10 minutes on/off).
  4. Immobilize the affected limb if possible.
  5. Remove rings/tight items near the sting area.
  6. Do not incise/suck wound, apply tourniquet, or use electric shock/traditional harmful measures.
(General supportive measures and cold packs are recommended in Harrison’s treatment section for scorpion stings, p. 13101.)

2) Assess severity

Mild/local envenomation
  • Local pain, tingling, mild swelling only
  • No cranial nerve, neuromuscular, respiratory, or cardiovascular signs
Concerning/systemic envenomation
  • Agitation, involuntary movements, cranial nerve findings
  • Excess salivation, sweating, vomiting
  • Tachycardia/hypertension, then possible hypotension/shock
  • Respiratory distress, pulmonary edema
  • Children are at higher risk of severe toxicity
(Harrison’s notes that nonlethal stings are often local-only; neuromuscular/cranial nerve symptoms indicate severe disease needing aggressive care, p. 13101.)

3) Treatment by setting

A) Home/Outpatient (mild cases only)

  • Oral analgesics (paracetamol/NSAID if appropriate)
  • Local cold compress
  • Observe for progression for several hours
  • Clear return precautions: breathing difficulty, drooling, restlessness, muscle jerks, persistent vomiting, worsening pain/swelling

B) Emergency department / hospital (systemic signs)

  • ABC stabilization, oxygen, IV access, cardiorespiratory monitoring
  • Treat pain and agitation (benzodiazepines can help with neuromuscular agitation; monitor closely for respiratory depression)
  • Manage BP abnormalities, arrhythmias, pulmonary edema as needed
  • Early toxicology/poison center consultation
  • Antivenom when moderate-severe systemic envenomation is present (species/region-specific availability and indications)
(Harrison’s: aggressive supportive care plus judicious antivenom for severe envenomation; midazolam infusion may control agitation/involuntary movements, with close respiratory monitoring, p. 13101.)

4) Antivenom: practical points

  • Most useful in clinically significant systemic toxicity, ideally early.
  • Use only antivenom appropriate to local scorpion species/available formulation.
  • Monitor for immediate hypersensitivity/anaphylaxis and delayed serum sickness.
  • In many regions, antivenom access and protocols vary; local poison center guidance is important.

5) Who should always be observed in hospital

  • Children (especially young/small body weight)
  • Elderly
  • Pregnancy
  • Patients with cardiopulmonary disease
  • Any patient with autonomic, neurologic, or respiratory symptoms

6) Red flags needing urgent transfer now

  • Difficulty breathing, wheeze, frothy sputum
  • Altered sensorium, severe agitation, jerking movements
  • Excess drooling, inability to swallow
  • Chest pain, persistent tachycardia or BP instability
  • Recurrent vomiting, worsening generalized symptoms
If you want, I can give a one-page ED protocol (triage, monitoring, drug sequence, and discharge criteria) tailored for adults vs pediatrics.
