Abstract:
Objective:To explore the difference of coagulation function and its correlation with prognosis in patients with acute respiratory distress syndrome (ARDS) caused by extrapulmonary sepsis and pulmonary infection.Methods:ARDS patients caused by extrapulmonary sepsis and pulmonary infection admitted to the ICU were retrospectively analyzed at the First Affiliated Hospital of China Medical University from July 2017 to June 2019. The clinical characteristics were collected including sequential organ failure assessment (SOFA), coagulation parameters [prothrombin time (PT), international normalized ratio (INR), activated partial thromboplastin time (APTT), fibrinogen (Fib), D-Dimer (D-D), fibrinogen degradation product (FDP), antithrombin Ⅲ(AT-Ⅲ), platelet (PLT)], duration of mechanical ventilation, length of stay (LOS) in ICU and 28-day mortality. According to the risk factors, the patients were divided into extrapulmonary sepsis group and pulmonary infection group. The correlation analysis between coagulation parameters and the prognosis of ARDS patients were analyzed by multivariate logistic regression analysis.Results:A total of 268 ARDS patients were screened and 28 cases were excluded. Finally, 240 ARDS patients were enrolled, including 145 caused by extrapulmonary sepsis and 95 by pulmonary infection. PT, INR and APTT in the extrapulmonary sepsis group were significantly higher than those in pulmonary infection group ( P<0.05). AT-Ⅲ level was lower than that in pulmonary infection group ( P<0.05). Ninty-three patients survived at 28 days in the non-pulmonary sepsis group, the mortality rate was 35.9% (52/145). PT, INR, APTT in patients who died at 28 days were significantly higher than those of the patients who survived ( P<0.05), while AT-Ⅲ level was lower than those of the patients who survived ( P<0.05). 49 patients survived at 28 days in the pulmonary infection group, the mortality rate was 48.4% (46/95). There was no significant difference in the coagulation parameters between two groups. Multivariate logistic regression analysis showed that SOFA score without PLT( OR=1.210,95% CI 1.067-1.372, P=0.003) and INR ( OR=2.408,95% CI 1.007-5.760, P=0.048) were independent risk factors for 28-day mortality in extrapulmonary sepsis group. Coagulation parameters are not independent risk factors for 28-day mortality in ARDS patients related to pulmonary infection. Conclusion:There are significant differences in coagulation function between ARDS patients caused by extrapulmonary sepsis or pulmonary infection. INR is an independent risk factor for 28-day mortality in extrapulmonary sepsis group.
