Abstract:
Objective:To observe the changes of lactate clearance rate (LCR) and serum polyligandosan-1 (SDC-1) in patients with septic shock complicated with acute respiratory distress syndrome (ARDS) and to evaluate its prognostic value.Methods:Patients with septic shock and ARDS who were admitted to the Respiratory Intensive Care Unit (RICU) of Zhengzhou Central Hospital Affiliated to Zhengzhou University from February 2021 to April 2022 were selected as subjects. The patients were divided into the survival group and death group according to their 28-day survival status. General clinical data and related indicators of patients in the two groups were collected and compared. The related factors influencing the 28-day death of patients with septic shock and ARDS were screened, and receiver operating characteristic (ROC) curve was drawn to evaluate the individual and combined forecast value of LCR and SDC-1 for the prognosis of patients with septic shock and ARDS.Results:Compared with the survival group, sequential organ failure score (SOFA) and acute physiology and chronic health status score Ⅱ(APACHE Ⅱ) at admission to RICU, the levels of 24 h Lac, 6 h SDC-1, 24 h SDC-1 and 72 h SDC-1 in the death group increased significantly (all P< 0.05), and the levels of 6 h LCR, 24 h LCR, 6 h OI, 24 h OI and 72 h OI significantly decreased (all P<0.05). Spearman correlation analysis showed that SDC-1 at 6 h, 24 h and 72 h was significantly negatively correlated with OI at corresponding time points (all P<0.05), and LCR at 6 h and 24 h was significantly positively correlated with OI at corresponding time points (all P<0.05). Multivariate Logistic regression analysis showed that SOFA score, 24 h LCR, 24 h SDC-1 and 72 h SDC-1 were the risk factors of 28-d death in patients with septic shock and ARDS (all P<0.05). The areas under ROC curve of each related factor were SOFA score, 24 h LCR, 24 h SDC-1 and 72 h SDC-1, which could predict the prognosis (all P<0.05). 24 h LCR combined with 24 h SDC-1 had the maximum area under the curve (AUC=0.805, 95% CI: 0.691-0.920, with a sensitivity of 75.0% and a specificity of 74.4%). Conclusions:24 h LCR, 24 h SDC-1 and 72 h SDC-1 are the risk factors of the 28-day death of patients with septic shock and ARDS. 24 h LCR combined with 24 h SDC-1 can improve the test efficiency compared with the single indicator.
