Quantification of lung water by transpulmonary thermodilution in normal and edematous lung.
To analyze the accuracy of the transpulmonary thermodilution method in the determination of extravascular lung water (EVLW). ⋯ The transpulmonary thermodilution method is very accurate to detect changes in EVLW in normal lungs. In edematous lung, this method may underestimate the EVLW.

PEEP decreases atelectasis and extravascular lung water but not lung tissue volume in surfactant-washout lung injury.
To examine the effects of positive end-expiratory pressure (PEEP) on extravascular lung water (EVLW), lung tissue, and lung volume. ⋯ The main findings are as follows: (a) PEEP effectively decreases EVLW. (b) The decrease in EVLW is closely correlated with the PEEP-induced decrease in nonaerated lung volume, making EVLW a valuable bedside parameter indicating alveolar recruitment, similar to measurements of transpulmonary shunt. (c) As excess tissue volume remained constant, however, EVLW may not be suitable to reflect overall severity of lung disease

The temporal evolution of lung injury following post-traumatic shock is poorly understood. In the present study we have tested the hypothesis that manifestations of pulmonary vascular dysfunction may be demonstrable within the first hour after the onset of shock. ⋯ Pulmonary vascular injury manifesting as relative pulmonary hypertension and increased PVR may occur within the first hour after the onset of shock. These changes may not be accompanied by overt changes in oxygenation, compliance, or EVLWi. Br J Anaesth 2003; 91: 224-32

Comparative Study
Perfusing and ventilating the patient's lungs during bypass ameliorates the increase in extravascular thermal volume after coronary bypass grafting.
To test the hypothesis that bilateral extracorporeal circulation (ECC) (Drew technique) ameliorates the increase in extravascular thermal volume (ETV) observed after conventional cardiopulmonary bypass (CPB) in patients undergoing coronary artery bypass grafting. ⋯ Despite a significantly greater prime volume and a more positive intraoperative fluid balance, ETV did not change with bilateral ECC but increased with conventional CPB. Thus, using the patient's lungs as an oxygenator during bypass mitigates the increase in extravascular pulmonary fluid.

Case Reports[Monitoring of extravascular lung water in patients with severe sepsis].
The key objective of the case study was the possibility to monitor the extravascular lung water (EVLW) in severe cases. Twelve mechanically ventilated patients with severe sepsis complicated by septic shock and by an acute lung injury (ALI) were involved in the prospective study. The measurements, performed on days 1 and 3 after the onset of sepsis, comprised hemodynamics, EVLW as assessed by Pulsion PiCCO method, blood gases and severity scores. ⋯ The EVLW and lung injury scores were found to be essentially higher in non-survivors on day 3. The clinical situations, described in the present article, are indicative of a potential EVLW value applicable to sepsis treatment. Finally, the monitoring of EVLW is a useful tool in the purpose-oriented therapy of sepsis-induced ALI; moreover, the method has an important prognostic value.
