Clinical diagnosis of fat embolism syndrome with septic shock following polytrauma: a case report.

Introduction And Importance: Fat embolism syndrome (FES) arises from the systemic effects of fat emboli in microcirculation. While sepsis is characterized by pathological, physiological, and metabolic abnormalities caused by infection. Septic shock is identified by elevated blood lactate (>2 mmol/l) and the need for vasopressors to maintain a mean arterial pressure of 65 mmHg or higher in the absence of hypovolemia.
