Hydrogen sulfide (H2S), better known as a poisonous gas, has emerged as the third gaseous transmitter in mammals, next to nitric oxide (NO) and carbon monoxide (CO). Increased production and higher serum concentrations were shown in inflammatory diseases, septic shock and stroke. The investigators will test the hypothesis that higher serum H2S concentrations on admission to intensive care unit (ICU) are linked with higher mortality in patients with shock of any reason.

Further study details as provided by University Medical Centre Ljubljana:

Primary Outcome Measures:
  • Prognostic value of H2S [ Time Frame: In hospital; ICU mortality 30days ] [ Designated as safety issue: Yes ]

    relationship between H2S and mortality of patients during intensive care treatment,

    comparison of H2S and lactate prognostic value

Secondary Outcome Measures:
  • Correlation of H2S with vasopressor requirements [ Time Frame: ICU treatmennt 30days ] [ Designated as safety issue: No ]
    relationship between H2S and dose of vasopressors (noradrenaline, epinephrine) used
