[Surviving Sepsis Campaign guideline update:problems and progress]

Sepsis is a clinical syndrome, the core of which is the disorder of the host's response to infection. Sepsis progresses to septic shock, which can lead to increased mortality, so early identification and standardized management are particularly important. Over the past 30 years, the definition of septic shock has gradually changed, with efforts to improve the identification and screening of early septic shock, and to emphasize the importance of organ dysfunction in patients with septic shock. The birth of the rescue systemic infection movement has played an important role in the management of septic shock patients. Although the cluster management of septic shock patients has reduced the overall mortality of septic shock patients, the management still faces many challenges. How to provide personalized treatment to patients, especially some controversial treatments, is still a major area for us to consider and explore.
