Comparative Study
Simplified lung ultrasound protocol shows excellent prediction of extravascular lung water in ventilated intensive care patients.
Ultrasound of the lung and quantification of B lines was recently introduced as a novel tool to detect overhydration. In the present study, we aimed to evaluate a four-region protocol of lung ultrasound to determine the pulmonary fluid status in ventilated patients in the intensive care unit. ⋯ Lung ultrasound is a useful, non-invasive tool in predicting hydration status in mechanically ventilated patients. The four-region protocol that we used is time-saving, correlates well with transpulmonary thermodilution measurements and performs markedly better than chest radiography.

Lung ultrasound (LUS) can diagnose extravacular lung water (EVLW) through the visualization of B lines in both humans and large animals. However, there are no published data on the use of ultrasound to detect EVLW in rats, the gold standard to evaluate of EVLW in rats is post-mortem gravimetric analysis. The present study was designed to determine the similarity between lung sonography and gravimetric measurements of EVLW in rats in an acute lung injury (ALI) model. ⋯ The data suggest that, in an experimental rat model of ALI, B lines score as assessed by LUS can provide an easy, semi-quantitative, noninvasive. Real-time index of EVLW which is strongly correlated to experimental gravimetric assessments.

[Assessment of fluid volume in critically ill patients with extravascular lung water index].
To examine the effect of rapid infusion test guided by extravascular lung water index ( EVLWI ) on hemodynamics in critically ill patients at different states in order to guide volume resuscitation. ⋯ Rapid fluid replacement in critically ill patients with crystalloid, regardless of whether the EVLWI was normal or increased, the short-term response was affected by the volume and cardiac function of patients. Different status of patients showed different volume effect curve: no significant changes in hemodynamic parameters were found in patients with normal EVLWI and volume parameters. In patients with potential cardiac dysfunction, CI and EVLWI increased significantly; regardless of PVPI increased or normal, EVLWI and CI were increased in patients with elevated EVLWI; two different changes could be found in the two types of pulmonary edema while ITBVI was increased.

[Value of detection of pentraxins 3 value combined with measurement of vascular lung water index in prognosis of patients with sepsis].
To evaluate prognostic value of pentraxin3 ( PTX3 ) content combining with extravascular lung water index ( EVLWI ) in patients with sepsis. ⋯ PTX3 can serve as a novel prognostic indicator at early stage in septic patients. Combined with EVLWI, it shows important value in predicting prognosis of septic patients, and it also provides guidance in treatment of high-risk patients.

Prognostic value of extravascular lung water assessed with lung ultrasound score by chest sonography in patients with acute respiratory distress syndrome.
The prognostic value of extravascular lung water indices (EVLWI) has been widely investigated, which is determined by lung ultrasound B-lines. However, the clinical value of lung ultrasound B-lines for determining prognosis/intensive care unit (ICU) outcomes in patients with acute respiratory distress syndrome (ARDS) has been rarely reported. ⋯ Lung ultrasonography is a non-invasive, economic, simple, user-friendly, and radiation-free bedside method for predicting the prognosis of ARDS patients. Early measurement of LUS is a better prognostic indicator in patients with ARDS.
