Background
- Colorless, flammable gas w/ rotten egg odor
- Encountered in oil/gas industries, natural product of decomposition (e.g. septic tank)
- Mechanism of toxicity is similar to CN (disruption of aerobic metabolism)
Clinical Features
- One of the few chemical asphyxiants that also possesses irritative properities
- Respiratory, ocular irritation
- High conc exposure may result in LOC, seizure, and death after only a few breaths
- Delayed pulm edema and corneal destruction should be anticipated w/ massive exposures
Treatment
- Decontamination of skin/eyes
- O2 100% NRB
- Consider giving nitrite component of CN kit (do not give thiosulfate portion)
- Low level MetHb may enhance conversion of sulfide to less toxic sulfmethemoglobin
