Sepsis is a serious infection that involves multiple organs and systems throughout the body, causing multiple organ failure and even death. The inflammation is not effectively controlled and treated, resulting in the proliferation of inflammation through the bloodstream and the spread of inflammation to other tissues and organs, causing a systemic inflammatory response, which can lead to the weakening of organs and the development of multiple organ failure, resulting in life-threatening conditions. This disease occurs mostly in patients after major surgery or serious diseases such as trauma and burns, and clinically in patients with heavy inflammation, such as pneumonia, peritonitis, meningitis, urinary tract infections of the urinary system, etc.
