Objective To evaluate the relationship between the extravascular lung water (EVLW) and other markers of lung injury and determine whether or not EVLW predicts survival in patients with acute respiratory distress syndrome (ARDS) and examine if indexing EVLW with predicted body weight (EVLWp) strengthens its discriminative power.Methods EVLW and other markers of lung injury [including:PaO2/FiO2(P/F),oxygenation index (OI) =mean pressure (Pm) × FiO2 × 100/PaO2,static compliance (Cst) and lung injury score (LIS)] were measured prospectively for 3 days in 27 patients with early ARDS between January 2011 and December 2011 at intensive care units (ICU) of Subei People's Hospital.The relationship between indexing EVLW with actual body weight (EVLWa),EVLWp and other markers of lung injury,the 28-day mortality were evaluated.Results Acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ),fluid balance in first 3 days,days of mechanical ventilation and ICU stay were significantly higher on admission in nonsurvivors compared with survivors (P < 0.05).Nonsurvivors had higher OI,LIS,EVLWa and EVLWp than survivors at Days 1 and 3 (P < 0.05).EVLWa and EVLWp were correlated positively with LIS (r =0.471,0.528 P < 0.05) and OI (r =0.527,0.627,P < 0.05) and negatively with P/F (r =-0.467,-0.646,P < 0.05).EVLWp had a stronger correlation to LIS,OI and P/F than did EVLWa.No obvious correlation existed between EVLWa,EVLWp and Cst (r =-0.260,0.226,P > 0.05).ROC curve analysis indicated that EVLWp (0.759,P < 0.05) but not EVLWa (0.661,P>0.05) discriminated between survivors and nonsurvivors.Three-dav average EVLWp ≥12.5ml/kg predicted the 28-day mortality with 62.5% specificity and 80% sensitivity.Conclusion Increased extravascular lung water is a feature of early ARDS and predicts survival.EVLWp,instead of EVLWa,improves the predictive value of extravascular lung water for survival and it is correlated with markers of disease severity.

Objective:To investigate the epidemiological characteristics of septic cardiomyopathy and explore the relationship between the relevant indexes measured by echocardiography and the prognosis of patients with sepsis.Methods:A case-control study was conducted. The data of patients with sepsis admitted to the department of critical care medicine of Jiangsu Subei People's Hospital Affiliated to Yangzhou University and the department of critical care medicine of Beijing Electric Power Hospital of State Grid Corporation of China from June 2018 to June 2021 were enrolled. The general information and 28-day prognosis were recorded. At the same time, ultrasonic parameters obtained by transthoracic echocardiography within 24 hours after intensive care unit (ICU) admission were recorded. The differences in ultrasound indexes between the death group and the survival group on 28 days were compared. Parameters with significant statistical differences between the death group and the survival group were included in the Logistic regression analysis to find the independent risk factors for the prognosis of patients with sepsis, the predictive value of each index for the prognosis of patients with sepsis was evaluated by receiver operator characteristic curve (ROC curve).Results:A total of 145 patients with sepsis were enrolled, including 106 patients with septic shock. Among the 145 patients, septic cardiomyopathy was found in 73 patients, with the incidence of 50.3%. The incidence of left ventricular diastolic dysfunction cardiomyopathy was 41.4% ( n = 60), the incidence of left ventricular systolic dysfunction cardiomyopathy was 24.8% ( n = 36), and the incidence of right ventricular systolic dysfunction cardiomyopathy was 12.4% ( n = 18). At 28 days, 98 patients survived and 47 died, with the mortality of 32.4%. The peak e' velocity by tissue Doppler imaging (e') and right ventricular myocardial systolic tricuspid annulus velocity (RV-Sm) of the death group were significantly lower than those of the survival group [e' (cm/s): 7.81±1.12 vs. 8.61±1.02, RV-Sm (cm/s): 12.12±2.04 vs. 13.73±1.74, both P < 0.05], left ventricular ejection fraction (LVEF) and left ventricular systolic mitral annulus velocity (LV-Sm) in the death group were slightly higher than those in the survival group [LVEF: 0.550±0.042 vs. 0.548±0.060, LV-Sm (cm/s): 8.92±2.11 vs. 8.23±1.71], without significant differences (both P > 0.05). Parameters with significant statistical differences between the two groups were included in the Logistic regression analysis and showed that e' and RV-Sm were independent risk factors for the 28-day prognosis of patients with sepsis [e': odds ratio ( OR) = 0.623, 95% confidence interval (95% CI) was 0.410-0.947, P = 0.027; RV-Sm: OR = 0.693, 95% CI was 0.525-0.914, P = 0.010]. ROC curve analysis showed that the area under the ROC curve (AUC) of e' for predicting the 28-day prognosis of patients with sepsis was 0.657, 95% CI was 0.532-0.781, P = 0.016, the best cut-off value was 8.65 cm/s, the sensitivity was 62.1%, and the specificity was 73.4%. The AUC of RV-Sm for predicting the 28-day prognosis of patients with sepsis was 0.641, 95% CI was 0.522-0.759, P = 0.030, the best cut-off value was 14.80 cm/s, the sensitivity was 96.6%, and the specificity was 26.6%. Conclusions:The incidence of septic cardiomyopathy is high. The LVEF measured by early echocardiography has no predictive value for 28-day prognosis in septic patients, while RV-Sm and e' are important predictors for 28-day prognosis.
