Abbreviations and measurement units: BMI: body-mass index; MAP: mean arterial pressure (mmHg); H.R.: heart rate (beats per minute); Temp: temperature (degrees Celsius); PaCO2: arterial carbon dioxide tension (mmHg); HCO3-: bicarbonatein arterial blood (mmol/L); PaO2/FiO2: arterial oxygen tension/fraction of inspired oxygen; Lact.: lactic acid in arterial blood (mmol/L); Hb.: hemoglobin (gr/L); Leuk.: leukocytes (x1000); Plat.: platelets (x1000); Serum urea (mg/dL); Creat.: serum creatinine (mg/dL); Na+: sodium ion (mmol/L); K+: potassium ion (mmol/L); INR: international normalized ratio; MR-proADM: mid-regional proadrenomedullin (nmol/L); ns: not significant.

 

Note: The means are expressed followed by standard deviation and refer to variables with normal distribution while the medians are expressed followed (in parentheses) of the interquartile range and refer to non-parametric variables.
