[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 correlated significantly with lung injury score (r = 0.46), oxygenation (r = -0.46) and with pulmonary compliance (r = -0.58) versus the central venous pressure. 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.
