Severe acute pancreatitis (SAP) is characterized by sudden onset, rapid progression, and high mortality, demonstrating marked time-dependence in its treatment. This article explores the application and significance of the "First-aid Philosophy" emphasizing "Early, Accurate, and Decisive" in the management of SAP. This article focuses on how this concept systematically optimizes SAP treatments [time-window-based goal management (e.g., early fluid resuscitation within 24 hours, early enteral nutrition), damage control strategies (e.g., avoiding early overly invasive interventions), synergy between causative and supportive treatments, and consistent multi-disciplinary therapy (MDT)] throughout patients' care. The core significance lies in integrating this proactive and decisive emergency mindset into practice to effectively block the progression of SAP, and ultimately to improve patients' prognosis.
