Abstract:
Objective:To analyze the influencing factors of death in patients with acute respiratory distress syndrome (ARDS) combined with acute kidney injury (AKI) in intensive care unit (ICU) after continuous renal replacement therapy (CRRT).Methods:The demographic and clinical data of ICU patients with ARDS combined with AKI after CRRT at Henan Provincial People's Hospital from January 1, 2018 to December 31, 2018 were collected. According to the final treatment results of this hospitalization, the patients were divided into death group and survival group. Survival was defined as the improved patient's condition and hospital discharge. Death was defined as the patient's death during the ICU hospitalization or confirmed death after abandoning treatment and automatically being discharged from the hospital in the follow-up. The basic clinical characteristics and CRRT status between the two groups were compared. Multivariate logistic regression method was used to analyze the influencing factors of death in patients.Results:A total of 132 patients were enrolled, of which 90 patients (68.2%) died, with 84 males (63.6%) and median age of 59(45, 73) years. Compared with the survival group, the death group had higher age, proportion of malignant tumors, sequential organ failure assessment (SOFA) score, number of organ dysfunction and proportion of positive balance of fluid accumulation at 72 hours, longer time from entering ICU to CRRT, and lower mean arterial pressure (minimum value) and oxygenation index (all P<0.05). Multivariate logistic regression analysis results showed that the age≥60 years old ( OR=4.382, 95% CI 1.543-12.440, P=0.006), large number of organ dysfunction ( OR=1.863, 95% CI 1.109-3.130, P=0.019), high SOFA score ( OR=1.231, 95% CI 1.067-1.420, P=0.004) and long time from ICU admission to CRRT ( OR=1.224, 95% CI 1.033~1.451, P=0.020) were independent influencing factors of death in patients with ARDS combined with AKI after CRRT, and high oxygenation index ( OR=0.992, 95% CI 0.986-0.998, P=0.010) was an independent protective factor for patients' prognosis. Conclusions:The mortality of patients with ARDS combined with AKI after CRRT is still high. The age≥60 years old, large number of organ dysfunction, high SOFA score and long time from ICU admission to CRRT are independent influencing factors for death, and high oxygenation index is an independent protective factor for prognosis in patients with ARDS combined with AKI after CRRT.
