hydrogen sulfide poisoning

poisoning by excessive exposure to hydrogen sulfide gas, seen primarily in those who work with petroleum or petrochemicals.

Treatments include immediate inhalation of amyl nitrate, injections of sodium nitrate, inhalation of oxygen, administration of bronchodilators, and, in severe cases, hyperbaric oxygen therapy.
