ABSTRACT
Objective:To investigate the correlation between oxygen metabolism index and prognosis of children with severe sepsis.Methods:A retrospective study was conducted.Children with severe sepsis admitted to the Department of Pedaitric Intensive Care Unit, Children′s Hospital Affiliated to Xi′an Jiaotong University from April 2016 to April 2019 were enrolled.Demographic data, hemodynamic-related indexes and oxygen metabolism indexes on admission were collected, and 28-day mortality was our primary outcome.According to the prognosis, the children were divided into survival group and death group.Baseline data, hemodynamic-related indexes and oxygen metabolism indexes on admission were compared between two groups.Binary Logistic regression was used to analyze the risk factors that may affect the prognosis, and relevant risk factors were analyzed by the receiver operator characteristic(ROC)curve to verify the predictability in prognosis.Results:A total of 170 children with severe sepsis were selected, including 79 died in 28-days with a 28-day mortality of 46.47%.There were no statistically significant differences in age, gender( P>0.05). Compared with survival group, the bloodstream infection and intracranial infection incidence were increased in the death group(all P<0.05). Compared with the survival group, blood lactate(Lac) and oxygen extraction ratio(ERO 2) were all increased in the death group[Lac: (7.58±2.64)mmol/L vs.(3.14±1.16) mmol/L, ERO 2: (45.12±11.39)% vs.(32.19±6.24)%, all P<0.05]; Oxygenation index(PO 2/FiO 2), mean arterial pressure(MAP), saturation of arterial blood oxygen(SaO 2), saturation of venous blood oxygen(SvO 2), cardiac index(CI) were all decreased[ PO 2/FiO 2: (237.75±130.37)mmHg vs.(319.25±150.85) mmHg, 1 mmHg=0.133 kPa; MAP: (49±4)mmHg vs.(61±15) mmHg; SaO 2: (62.29±15.16)%vs.(83.21±16.09) %; SvO 2: (57.28±24.02)% vs.(65.32±13.15) %; CI: (1.68±0.76)mL/(min·m 2) vs.(2.56±0.25) mL/(min·m 2), all P<0.05]. The binary Logistic regression showed that Lac and ERO 2 were independent risk factors affecting the prognosis of children with severe sepsis, and the difference was statistically significant[ OR(95% CI) were 2.00(1.14-3.51)and 1.83(1.09-4.05), respectively, all P<0.05]. ROC curve analysis showed that the area under ROC curve of Lac and ERO 2 were 0.675 and 0.789, respectively.Sensitivity to predict death in children with severe sepsis were 93.75% and 85.31%, respectively, whose specificity were 87.85% and 78.39%, respectively.The combined prediction area under ROC curve of Lac and ERO 2 was 0.946, with a sensitivity of 89.15% and specificity of 88.76%, and the differences were statistically significant(all P<0.05). Conclusion:Lac and ERO 2 are independent risk factors affecting children with severe sepsis, and their combination has a good predictive value for the prognosis of children with severe sepsis.
