Patients with suspected or confirmed sepsis usually present with hypotension, tachycardia, fever, and leukocytosis. As the condition worsens, signs of shock (e.g., skin chills and cyanosis) and signs of organ dysfunction (e.g., oliguria, acute kidney injury, and altered mental status) develop. It is important to note that these manifestations are nonspecific, and many other conditions (e.g., pancreatitis, acute respiratory distress syndrome) can present similarly. Septicemia is a syndrome of organ dysfunction resulting from a dysregulation of the body’s response to infection. It may be caused by bacteria, fungi, viruses and parasites. The main symptoms are chills, fever, panic, and altered mental status. It may develop into severe sepsis and septic shock, leading to life-threatening organ function and circulatory disorders. If the patient with sepsis develops symptoms such as persistent hypotension, oliguria, thin and rapid pulse, and altered consciousness, he should be rescued and treated in the hospital immediately.
