Extravascular Lung Water and Pulmonary Vascular Permeability Index as Markers Predictive of Postoperative Acute Respiratory Distress Syndrome: A Prospective Cohort Investigation.
Robust markers of subclinical perioperative lung injury are lacking. Extravascular lung water indexed to predicted body weight and pulmonary vascular permeability index are two promising early markers of lung edema. We aimed to evaluate whether extravascular lung water indexed to predicted body weight and pulmonary vascular permeability index would identify patients at risk for clinically significant postoperative pulmonary edema, particularly resulting from the acute respiratory distress syndrome. ⋯ Perioperative extravascular lung water indexed to predicted body weight is an early marker that predicts risk of clinically significant postoperative pulmonary edema in at-risk surgical patients. Pulmonary vascular permeability index effectively discriminated postoperative acute respiratory distress syndrome from cardiogenic pulmonary edema. These measures will aid in the early detection of subclinical lung injury in at-risk surgical populations.

[ASSESSMENT OF EXTRAVASCULAR LUNG WATER BY QUANTITATIVE COMPUTER IMAGE ANALYSIS IN PATIENTS WITH ACUTE RESPIRATORY DISTRESS SYNDROME].
To evaluate the possibility of quantitative computed tomography (CT) of the lungs in patients with acute respiratory distress syndrome (ARDS) for assessment of the severity of the condition and the effectiveness of treatment. ⋯ Quantitative analysis of CT reveals changes in the mass and volume of the lungs and can be used to diagnose and evaluate the effectiveness of the treatment. Pulmonary weight calculated by CT correlates with EVLW determined by TTD.

Multicenter Study Observational StudyNear-normal values of extravascular lung water in children.
To define near-normal values of extravascular lung water indexed to body weight in children. ⋯ Younger children have higher values of extravascular lung water indexed to actual body weight. Age categorized near-normal values of extravascular lung water indexed to body weight are presented for possible clinical use. Furthermore, we suggest to index extravascular lung water to height, which seems to be age independent.

Observational StudyAccuracy of ultrasound B-lines score and E/Ea ratio to estimate extravascular lung water and its variations in patients with acute respiratory distress syndrome.
Extravascular lung water (EVLW) could increase by permeability pulmonary oedema, cardiogenic oedema, or both. Transthoracic echocardiography examination of a patient allows quantifying B-lines, originating from water-thickened interlobular septa, and the E/Ea ratio, related to pulmonary capillary wedge pressure. The aim of our study was to assess the correlation and the trending ability between EVLW measured by transpulmonary thermodilution and the B-lines score or the E/Ea ratio in patients with ARDS. ⋯ A B-lines score≥6 had a sensitivity of 82% and a specificity of 77% to predict EVLW>10 ml/kg, with an AUC equal to 0.86 (0.76-0.93). The gray zone approach identified a range of B-lines between four and seven for which EVLW>10 ml/kg could not be predicted reliably. The correlation between ultrasound B-lines and EVLW was significant, but the B-lines score was not able to track EVLW changes reliably.
