Défaillance cardiaque et neurologique secondaire à une intoxication accidentelle par l’hydrogène sulfuré : à propos d’un cas

Sewer gas poisoning causing transient and focal ST-segment elevation in the ECG: Case report

“…Sewer gas can lead to both left ventricular systolic dysfunction and chemical pneumonitis, both of which contribute to the pathophysiology of the development of ARDS. [ 6 ] In our case also, the patient developed reduced cardiac output along with ARDS. ARDS can be explained because of direct toxicity of various gases or because of direct effects on the heart leading to reduced contractility of the myocardium, further increasing alveolar oedema.…”

Hydrogen sulphide inhalational toxicity at a petroleum refinery in Sri Lanka: a case series of seven survivors following an industrial accident and a brief review of medical literature

“…H 2 S has been known to characteristically cause sudden loss of consciousness which is colloquially termed 'knockdown' [3,6]. Coma is often associated with severe poisonings by H 2 S [7]. Recent studies have shown that neurons have relatively high H 2 S levels that act as messengers and therefore H 2 S is a neuromodulator [8].…”

“…Studies in rats have demonstrated morpho-functional alterations in the aero-hemic barrier and surfactant system of the lungs with resultant pulmonary oedema [16]. Acute respiratory failure caused by an acute pulmonary oedema with left ventricular systolic dysfunction as a possible cause of this cardiorespiratory complication has been purported in medical literature [7]. Exposure to higher concentrations increase the risk of pulmonary oedema [3].…”
