4.2 Most important symptoms/effects, acute and delayed

Caustic action on skin and eyes. If ingested may liberate hydrogen sulfide in stomach. (USCG, 1999)

4.3 Indication of immediate medical attention and special treatment needed, if necessary

For advanced treatment: Consider orotracheal or nasotracheal intubation for airway control in the patient who is unconscious or in respiratory arrest. Positive-pressure ventilation techniques with a bag-valve-mask device may be beneficial. Monitor cardiac rhythm and treat arrhythmias if necessary . Start an IV with D5W TKO /SRP: To keep open, "minimal flow rate"/. Use lactated Ringer's if signs of hypovolemia are present. Watch for signs of fluid overload. Consider drug therapy for pulmonary edema . For hypotension with signs of hypovolemia, administer fluid cautiously. Watch for signs of pulmonary edema. Consider vasopressors to treat hypotension without signs of hypovolemia . Treat seizures with diazepam (Valium) . In severe cases use amyl nitrite and sodium nitrite ... as described for cyanide poisoning; omit the sodium thiosulfate injection. Early administration will be the most effective. DIRECT PHYSICIAN ORDER ONLY . Use proparacaine hydrochloride to assist eye irrigation . For basic treatment: Establish a patent airway. Suction if necessary. Watch for signs of respiratory insufficiency and assist ventilations if necessary. Administer oxygen by nonrebreather mask at 10 to 15 L/min. Monitor for pulmonary edema and treat if necessary . Monitor for shock and treat if necessary . Anticipate seizures and treat if necessary . For eye contamination, flush eyes immediately with water. Irrigate each eye continuously with normal saline during transport . Treat with rapid rewarming techniques ... if frostbite occurs. Hydrogen sulfide and related compounds
