Blood samples were immediately drawn upon admission. The serum lactate levels in mmol/L (ADVIA Chemistry XPT^® LAC Assay, Siemens, Germany; reference level 0.5.2.2 mmol/L) were assessed as a serum biomarker for CP parameters. Furthermore, C-reactive protein (CRP) in mg/L (ADVIA Chemistry XPT^®, Siemens, Germany), white blood cell count in giga/L (XE 5000 Hematology Analyzer, Sysmex, Germany), hemoglobin levels in g/dL (XE 5000 Hematology Analyzer, Sysmex, Germany), hematocrit levels in L/L (XE 5000 Hematology Analyzer, Sysmex, Germany), cholinesterase in U/L (ADVIA Chemistry XPT^®, Siemens, Germany), blood glucose levels in mg/dL (ADVIA Chemistry XPT^®, Siemens, Germany), pH values (ABL800 FLEX; Radiometer, Copenhagen, Denmark and Krefeld, Germany), albumin levels in g/L (ADVIA Chemistry XPT^®, Siemens, Germany), creatinine in mg/dL (ADVIA Chemistry XPT Crea assay, Siemens, Germany), cortisol levels in µg/dL (ADVIA Centaur XPT^®, Siemens, Germany), and troponin I in µg/dL (ADVIA Centaur XPT^®, Siemens, Germany) upon admission were analyzed in the entire study population.

Blood samples were immediately drawn upon the patients’ admission to the neurosurgical department. Serum lactate levels in mmol/L (ADVIA Chemistry XPT^® LAC Assay, Siemens, Germany) were defined as serum biomarkers for CP parameters. In addition, white blood cell count in giga/L (XE 5000 Hematology Analyzer, Sysmex, Germany), hemoglobin level in g/dL (XE 5000 Hematology Analyzer, Sysmex, Germany), hematocrit level in L/L (XE 5000 Hematology Analyzer, Sysmex, Germany), cholinesterase in U/L (ADVIA Chemistry XPT^®, Siemens, Germany), blood glucose level in mg/dL (ADVIA Chemistry XPT^®, Siemens, Germany), serum lactate level in mmol/L (ADVIA Chemistry XPT^®, Siemens, Germany), troponin I in µg/dL (ADVIA Centaur XPT^®, Siemens, Germany), cortisol level in µg/dL (ADVIA Centaur XPT^®, Siemens, Germany), C-reactive protein (CRP) in mg/L (ADVIA Chemistry XPT^®, Siemens, Germany), albumin level in g/L (ADVIA Chemistry XPT^®, Siemens, Germany), creatine in mg/dL (ADVIA Chemistry XPT Crea assay; Siemens, Germany), prothrombin time in % (Atellica^® COAG 360 System, Siemens, Germany), partial thromboplastin time in sec (Atellica^® COAG 360 System, Siemens, Germany), antithrombin III in %/NORM (Atellica^® COAG 360 System, Siemens, Germany), and fibrinogen in g/L (Atellica^® COAG 360 System, Siemens, Germany) upon admission were recorded and analyzed in all of the included patients.
