Sepsis and septic shock result from a dysregulated host response to infection that leads to organ dysfunction. Management involves immediate resuscitation within 1 hour with IV fluids, antibiotics, and vasopressors if needed. Ongoing care includes source control, frequent reassessment of volume status, and supportive care such as mechanical ventilation and nutrition. The goals are to treat the underlying infection while supporting failing organs until the host response normalizes. Sepsis affects millions worldwide and requires swift treatment to prevent progression to septic shock and death.
