Background
- White phosphorus is classically among only 2 chemical burns (other is Hydrofluoric Acid) that required an antidote
- The antidote of copper sulfate is controversial and is not universally recommended
- Incendiary agent that spontaneously burns in air and used during WWI, WWII, Vietnam, Korean wars; most recently in Iraq (OIF)
- Usually not seen unless in military or patients exposed to fireworks
- Damage due to both chemical and thermal burns
- The lethal dose when white phosphorus is ingested orally is 1mg per kg of body weight[1][2]
- Particles that penetrate tissue continue to cause caustic damage until debrided
Clinical Features
- Hypocalcemia
- Hypophosphatemia
- Hepatic necrosis
- Death may occur from burns of only 10-15% total body surface area (TBSA)
Differential Diagnosis
Chemical weapons
- Blister chemical agents (Vesicants)
- Lewisite (L)
- Sulfur mustard (H)
- Phosgene oxime (CX)
- Pulmonary chemical agents (Choking agents)
- Incendiary agents
- Cyanide chemical weapon agents (Blood agents)
- Prussic acid (AKA hydrogen cyanide, hydrocyanic acid, or formonitrile)
- Nerve Agents (organophosphates)
- Acetylcholinesterase inhibitors
- Household and commercial pesticides (diazinon and parathion)
- G-series (sarin, tabun, soman)
- V-series (VX)
- Lacrimating or riot-control agents
- Pepper spray
- Chloroacetophenone
- CS
Evaluation
Management
- ABCs to secure airway especially if there is any sign of oral or facial burns.
- Remove all O2 tanks and tubing from patient
- As healthcare provider, avoid contact with ignited white phosphorus
- Continuous irrigation and grossly debride (use Wood's lamp if available to fluoresce the white phosphorus)[3]
- Wet dressings that cut off O2 exposure to remaining white phosphorus[4]
- Monitor Calcium and Phosphorus levels
- Copper sulfate
- Traditionally used to both convert white phosphorus and visualize end product (cupric phosphate)
- However, is systemically absorbed and may lead to intravascular hemolysis, renal Failure, and cardiovascular collapse
- Update Tetanus
Disposition
- Transfer the the patient to a burn care center
