Accurate quantification of extravascular lung water is an important issue in the management of patients with pulmonary edema. The single transpulmonary thermal indicator method has been available since the late 1990s. Its simplicity and easy application make it clinically attractive. ⋯ Extravascular lung water can be considered a relevant parameter that contributes to rational management of fluid and vasoactive therapy of many critically ill patients and offers a fuller picture of their overall lung function.

Pulmonary edema is the most frequent postoperative complication following esophagectomy for thoracic esophageal cancer. We enrolled 23 patients who underwent esophagectomy with extended lymph node dissection for thoracic esophageal cancer in a prospective observational clinical trial. We used the PiCCO device to measure extravascular lung water with the aim of determining whether it correlates with the respiratory index and whether it is predictive of pulmonary complications. ⋯ The extravascular lung water measured using PiCCO correlated significantly with the respiratory index. In the intubation group, both extravascular lung water and respiratory index were elevated 12 h after surgery and were even higher 24 h after surgery. The extravascular lung water measured using PiCCO reflects the level of postoperative pulmonary edema and predicts the pulmonary complications induced by esophagectomy with extended lymph node dissection.

Case Reports[A case of idiopathic ARDS treated by sivelestat sodium and fluid management based on extravascular lung water index].
A 65-year-old woman was given emergency admission with fever, cough and dyspnea. Chest computed tomography (CT) findings showed bilateral ground-glass opacity, consolidation, and this case were fulfilled the criteria for acute respiratory distress syndrome (ARDS). ⋯ We found this treatment quite effective because there were significant improvements in the extravascular lung water index (EVLWI) measured by the PiCCO system and neutrophile elastase value and in oxygenation and the chest radiograph. This is apparently the first case report in the literature that clearly shows the treatment with sivelestat sodium and strict fluid management ended in a favorable outcome, as reducing EVLWI measured by the PiCCO system in an idiopathic ARDS patient.

[Pulmonary extravascular water in patients with acute respiratory failure].
The purpose of the investigation was to study pulmonary extravascular water levels and pulmonary vascular permeability (PVP) in the pathogenesis of acute respiratory failure (ARF)/acute respiratory distress syndrome (ARDS). Twenty-nine patients with ARF/ARDS and 10 healthy volunteers were examined. Central hemodynamics and oxygen transport were explored, by using a Swan-Ganz catheter. ⋯ Arterial hypoxemia is associated with the increase in the shunt, but, in a portion of patients, the shunt was caused with atelectasis unassociated with pulmonary edema. Increased pulmonary permeability for transferrin is detectable in ARF/ARDS irrespective the severity of pulmonary edema. The pathogenetic features of lung lesions should be taken into account while choosing a treatment for ARF/ARDS.

Extravascular lung water to blood volume ratios as measures of permeability in sepsis-induced ALI/ARDS.
We studied the relationship, and the effect of fluid loading on this, between the ratio of extravascular lung water (EVLW) to intrathoracic/pulmonary blood volumes (ITBV, PBV) and the radionuclide pulmonary leak index (PLI) to protein during sepsis-induced acute lung injury/acute respiratory distress syndrome (ALI/ARDS). ⋯ The data demonstrate that EVLW/ITBV or EVLW/PBV are imperfect measures of increased protein permeability in mechanically ventilated patients with sepsis-induced ALI/ARDS particularly when the PLI is severely increased and during pneumonia, independent of fluid status.
