Detailní popis
Traumatic brain injury is a major cause of morbidity and mortality worldwide and represents a significant challenge in intensive care units. In addition to the primary neurological damage, patients with moderate to severe traumatic brain injury frequently develop systemic inflammatory responses that may lead to secondary organ dysfunction. These systemic effects are mediated by activation of inflammatory cytokines, endothelial injury, and coagulation abnormalities.
Acute respiratory distress syndrome is a common and serious complication in patients with traumatic brain injury, even in the absence of direct chest trauma. Epidemiological studies indicate that acute respiratory distress syndrome develops in approximately 19-30% of severe traumatic brain injury patients, typically within the first week after injury, with a median time to onset of around 3 days.
The fibrinogen-to-albumin ratio has recently emerged as a novel biomarker reflecting both inflammatory and nutritional status. Fibrinogen is a positive acute-phase reactant that increases in response to inflammation and tissue injury, while albumin is a negative acute-phase protein that decreases during systemic inflammatory states. Previous studies have demonstrated that fibrinogen-to-albumin ratio is altered in patients with traumatic brain injury and correlates with injury severity and clinical outcomes.
Given that the same inflammatory and coagulation pathways influencing fibrinogen-to-albumin ratio in traumatic brain injury also play a central role in the development of acute respiratory distress syndrome, it is biologically plausible that early fibrinogen-to-albumin ratio measurements may predict acute respiratory distress syndrome occurrence in this patient population. However, the predictive value of fibrinogen-to-albumin ratio for acute respiratory distress syndrome in patients with traumatic brain injury has not yet been adequately investigated.

Acute respiratory distress syndrome group
patients who will develop ARDS within 7 days of ICU admission, defined according to the Berlin criteria. Fibrinogen (g/L) and albumin (g/L) levels in the blood will be measured from the first routine blood sample after ICU admission. Fibrinogen-to-albumin ratio will be calculated as: FAR = Fibrinogen (g/L)/Albumin (g/L) |
Fibrinogen (g/L) and albumin (g/L) levels in the blood will be measured from the first routine blood sample after ICU admission. Fibrinogen-to-albumin ratio will be calculated as: FAR = Fibrinogen (g/L)/Albumin (g/L) |
|
Non acute respiratory distress syndrome group
patients who will not develop ARDS within 7 days of ICU admission. Fibrinogen (g/L) and albumin (g/L) levels in the blood will be measured from the first routine blood sample after ICU admission. Fibrinogen-to-albumin ratio will be calculated as: FAR = Fibrinogen (g/L)/Albumin (g/L) |
