研究目的: |
系统分析降钙素原(PCT)动态特征(峰值下降率、谷值水平、达标时间)与脓毒症患者短期(28 天 / 90 天死亡率、器官功能损伤)及长期(6 个月 - 1 年再感染率、再住院率)预后的关联,明确其预后评估价值。 |
||||||||||||||||||||||
|
Objectives of Study: |
To systematically analyze the correlation between the dynamic characteristics of procalcitonin (PCT) (peak decline rate, trough level, time to reach the standard) and the short-term (28-day/90-day mortality, organ function injury) and long-term (6-month to 1-year reinfection rate, readmission rate) prognosis of patients with sepsis, and clarify its prognostic evaluation value. |
