II. Management: Approach
- ABC Management
-
Decontamination Immediately
- Hypochlorite 0.5%
- M291 Kit
- Copious amounts of water
- Systemic Antidote for suspected severe exposure
- Sodium thiosulfate (sulfur donor)
- May be helpful if given within 20 minutes
- British-Anti-Lewisite (BAL, Dimercaprol) IM
- Indicated only if Lewisite exposure suspected
- Used now to chelate Heavy Metals
- Reduces Lewisite systemic effects
- Topical BAL for eye and skin also effective
- Caution: Potential significant adverse effects
- Sodium thiosulfate (sulfur donor)
- Other agents with potential benefit
- Supportive care
- Hydration
- Moderate fluid Resuscitation
- Losses are not nearly as great as for burn patients
- Systemic Analgesics and antipruritics
- Consider Parenteral nutrition
- Hydration
III. Management: Skin Changes
- Erythema
- Calamine or 0.25% camphor/Menthol/calamine
-
Blisters
- Unroofing larger Blisters (>2 cm) is controversial
- Denuded skin
- Irrigate 3-4 times per day with saline
- Cover liberally with Silver Sulfadiazine or mafenide
- Topical Antibiotics for unroofed skin Blisters
- Whirlpool bath irrigation for large involvement
- Fluid therapy associated with burns
- Less fluid needed than in standard Burn Management
IV. Management: Eye Changes
-
Conjunctival irritation
- Homatropine ophthalmic ointment
- Prevents synechiae formation
- Erythromycin ointment or other Topical Antibiotic
- Vaseline to Eyelids
- Prevents adhesions and scarring
- Permits drainage of underlying infection
- Topical Steroids may be useful in first 48h
- Confirm no concurrent infection
- Usually heals in 1-3 weeks
- Homatropine ophthalmic ointment
- Pain
- Avoid Topical Analgesics except for Eye Exam
- Use systemic Analgesics
- Sunglasses for photophobia
V. Management: Pulmonary Changes
- Upper airway effects (Pharyngitis, cough)
- Steam inhalation
- Cough Suppressants
- Lower airway effects (Productive cough, Dyspnea)
- Avoid Antibiotics in first 24 hours
- Usually sterile Bronchitis or pneumonitis
- Respiratory Infection onset at 72 hours
- Evaluate clinically (fever, Sputum Gram Stain)
- Bronchodilators
- Consider systemic or Inhaled Steroids
- Avoid Antibiotics in first 24 hours
- Impending Airway compromise
VI. Management: Gastrointestinal Changes
- Antiemetic prn
VII. Management: Severe Marrow Suppression
-
Granulocyte Colony Stimulating Factor (GCSF, Neupogen)
- Resource: Bill Young Marrow Donor (1-800-MARROW-3)
