Accurate characterization of extravascular lung water in acute respiratory distress syndrome.
Measurements of extravascular lung water (EVLW) correlate to the degree of pulmonary edema and have substantial prognostic information in critically ill patients. Prior studies using single indicator thermodilution have reported that 21% to 35% of patients with clinical acute respiratory distress syndrome (ARDS) have normal EVLW (<10 mL/kg). Given that lung size is independent of actual body weight, we sought to determine whether indexing EVLW to predicted or adjusted body weight affects the frequency of increased EVLW in patients with ARDS. ⋯ Indexing EVLW to PBW or AdjBW reduces the number of ARDS patients with normal EVLW and correlates better to Lung Injury Score and oxygenation than using ActBW. Studies are needed to confirm the presumed superiority of this method for diagnosing ARDS and to determine the clinical treatment implications.

Multiple artifacts B lines (B+) at transthoracic lung ultrasound have been proposed as a sonographic sign of pulmonary congestion. Our aim is to assess B+ clearance after medical treatment in acute decompensated heart failure (ADHF) and to compare the usefulness of sonography with other traditional tools in monitoring resolution of pulmonary congestion. ⋯ B line pattern mostly clears after adequate medical treatment of ADHF and represents an easy-to-use alternative bedside diagnostic tool for clinically monitoring pulmonary congestion in patients with ADHF.

[Effects of small volume resuscitation on the hemodynamics and extravascular lung water of septic shock dogs].
To observe the effect of small volume resuscitation by hypertonic-hyperoncotic solution on the hemodynamics and extravascular lung water of septic shock dogs. ⋯ All these four solutions can improve the hemodynamics of septic shock dogs. Small volume hypertonic-hyperoncotic solution has a similar effect in hemodynamics as NS, HS, and HES. Meanwhile, it does not increase the extravascular lung water.
