Hydrogen Sulfide Poisoning in a Hospital Setting

The Emerging Roles of Hydrogen Sulfide in the Gastrointestinal Tract and Liver

“…This procedure has been successfully used in the resuscitation of several victims of H 2 S poisoning. 9,10 Sulfur Amino Acid Metabolism Sulfur-containing amino acids are the key precursors for endogenous H 2 S synthesis. They are also important factors for cellular stability-through their antioxidant and scavenging properties-and have many metabolic functions.…”

Hydrogen sulfide toxicity: two case reports

“…21 Low and moderate exposure to hydrogen sulfide mainly causes local tissue irritation with cyanosis, coma and rapid death in severe exposure. [22][23][24][25] Minimal local reaction due to H2S in these two individuals indicated that victims were exposed to high level of H2S than lower level. Mild frothy fluid seen on cut sections of lungs in both the diseased indicates the possibility of asphyxia due to rapid exposure to high concentrations than local irritation which occurs in low and moderate exposure.…”

Hydrogen Sulfide

“…103 Hyperbaric oxygen treatment is safe in skilled hands but transport to a facility should not delay supportive care, which is a more important factor in survival. 48,107 –109…”

“…103 Hyperbaric oxygen treatment is safe in skilled hands but transport to a facility should not delay supportive care, which is a more important factor in survival. 48,[107][108][109] Nitrite treatment is based on the theory that methemoglobin generated by nitrite would displace the sulfide, as it does cyanide, and regenerate the active cytochrome oxidase. 99 Although methemoglobin is more effective in binding sulfide than oxyhemoglobin, the complex between sulfide and methemoglobin does not last long enough to make a difference.…”
