There is no difference between sepsis and septicemia; they are the same disease. Sepsis and septicemia are both diseases caused by dysfunction of organs due to dysregulation of the body’s response to inflammation, which can be triggered by infections in any part of the body as well as severe trauma, and the two names actually refer to the same disease, with septicemia being the name in the past, and now clinically referred to as sepsis. At the onset of sepsis, symptoms such as fever (or hypothermia), panic, abnormal mental status, shortness of breath, chills, etc. usually occur. As the disease progresses, without timely intervention, there is also the possibility of developing severe sepsis and septic shock, which can lead to serious consequences such as dysfunction of the cardiovascular, cerebral, pulmonary, renal, and other organs, insufficient perfusion of the tissues, impaired consciousness, and death. In order to prevent the occurrence of the above symptoms, those who are diagnosed with sepsis should actively cooperate with professional doctors for treatment.
