CRP/Albumin Ratio as a Predictive Inflammatory Marker for Postoperative SIRS and/or Sepsis
Study Details
Study Description
Brief Summary
The goal of this observational study is to determine the value of CRP/Albumin Ratio as an inflammatory marker for predicting the development of postoperative Systemic Inflammatory Response Syndrome and/or Sepsis in polytraumatized patients admitted to Intensive care unit.
The main question it aims to answer is whether CRP/Albumin Ratio can be used as predictive inflammatory marker for postoperative Systemic Inflammatory Response Syndrome and/or Sepsis or not.

Detailed Description
The development of postoperative Systemic Inflammatory Response Syndrome (SIRS) or Sepsis is a very serious complication that has been associated with high morbidity, mortality, and increased length of inpatient stay.
Sepsis is a life-threatening organ dysfunction caused by a dysregulated host response to infection.
As surgical interventions lead to well-understood metabolic, neuroendocrine, and immune responses, the stress responses to surgery contribute to increased postoperative complications mostly caused by increased levels of Pro-inflammatory cytokines in response to surgical injury, which leads to changes of circulating acute phase proteins, such as albumin and C-reactive protein (CRP).
The CRP to albumin ratio (CAR) is a new index calculated by dividing CRP by the albumin level. It has been assumed to have predictive value in determining morbidity and mortality in many critical diseases.
