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.
