Demographics of 16 patients with ARDS vs. 13 patients with hydrostatic edema
| Clinical Characteristics | ARDS (n = 16) | Hydrostatic Edema (n = 13) | P Value |
|---|---|---|---|
| Age | 42 [36.5, 49] | 53 [34, 66] | 0.33 |
| Sex, %men | 50% | 62% | 0.71 |
| Vasopressor use | 75% | 46% | 0.15 |
| Mortality | 44% | 15% | 0.13 |
| Edema fluid:plasma protein ratio | 0.84 [0.76, 0.96] | 0.44 [0.41, 0.54] | 1 × 10−5 |
| Primary diagnosis | 4 × 10−5 | ||
| Type (no. of cases) | Pneumonia (4), sepsis (4), anaphylaxis (2), aspiration (1), TRALI (2), fulminant hepatic failure (1), reperfusion edema (1), tumor lysis (1) | Volume overload/hydrostatic edema (5), myocardial infarction/ischemia (2), cardiac arrest (1), postobstructive (2), cardiogenic shock (1), TACO (1), neurogenic (1) |
Median [interquartile range (IQR)], with P value by Wilcoxon’s rank sum for continuous variables and Fisher’s exact for categorical variables, is shown. ARDS, acute respiratory distress syndrome; TACO, transfusion-associated cardiac overload; TRALI, transfusion-associated lung injury; Sepsis, nonpulmonary source of sepsis.
