BACKGROUND: The purpose of this study was to determine: (1) whether stable heart failure patients with reduced ejection fraction (HFrEF) have elevated extravascular lung water (EVLW) when compared with healthy control subjects; and (2) the effect of acute β2-adrenergic receptor (β2AR) agonist inhalation on lung fluid balance. METHODS: Twenty-two stable HFrEF patients and 18 age- and gender-matched healthy subjects were studied. Lung diffusing capacity for carbon monoxide (DLCO), alveolar-capillary membrane conductance (DmCO), pulmonary capillary blood volume (Vc) (via re-breathe) and lung tissue volume (Vtis) (via computed tomography) were assessed before and within 30 minutes after administration of nebulized albuterol...

BACKGROUND: The synthetic peptide solnatide is a novel pharmacological agent that reduces extravascular lung water, blunts reactive oxygen species production and improves lung function due to its ability to directly activate the epithelial sodium channel ENaC. We aimed to investigate the effect of solnatide in pulmonary edema induced by acute hypobaric hypoxia and exercise in rats, which is considered a model for high altitude pulmonary edema. METHODS: Sprague-Dawley rats were assigned to low altitude control and eight treatment groups...

BACKGROUND: Lung ultrasounds show vertical artifacts known as B-lines in the presence of increased extravascular lung water (EVLW). We aimed to investigate whether lung ultrasound could estimate EVLW after congenital cardiac surgery. METHODS: This prospective observational study comprised 61 children (age range 3 days to 7.4 years) undergoing congenital cardiac surgery. We compared postoperative B-line scores from lung ultrasounds, early postoperative ultrasound as our primary interest, with corresponding postoperative chest radiography (CXR) lung edema scores, with static lung compliance, and with short-term clinical outcome interpreted as time on mechanical ventilation and length of pediatric intensive care unit (PICU) stay...

OBJECTIVE: To evaluate lung and cardiac ultrasound for the assessment of fluid tolerance and fluid responsiveness before and after delivery in pregnant women with severe pre-eclampsia (PE). METHODS: This was a prospective observational study of singleton pregnant women with severe PE and healthy term controls. Lung ultrasound echo comet score (ECS), which denotes the amount of extravascular lung water, was obtained using the 28-rib interspaces technique. The echocardiographic E/e' ratio, measured by pulsed-wave and tissue Doppler, was used as a marker of diastolic left ventricular function...

INTRODUCTION: The ability to judge intravascular volume is fundamental in the management of patients with severe preeclampsia. Insufficient intravascular volume can result in decreased oxygen delivery to tissues and exacerbates organ dysfunction. On the other hand, fluid excesses can lead to fluid extravasation and pulmonary edema. Outside of pregnancy, transthoracic echocardiography and lung ultrasonography have become important diagnostic and monitoring tools in critically ill patients...

OBJECTIVES: Recent literature suggests that bedside lung ultrasound may have a role in the evaluation of infants with bronchiolitis. B lines, which are multiple and diffuse vertical artifacts spreading from the lung pleural interface to the edge of the ultrasound screen, have been associated with thickened interlobular septa, extravascular lung water, and diffuse parenchymal disease. The aims of this study were (1) to describe the prevalence of B lines in children younger than 24 months presenting to the emergency department with wheezing, (2) to determine the interrater reliability of lung ultrasound findings in this setting, and (3) to determine the association of B lines with atopy and other clinical findings...

BACKGROUND/PURPOSE: Postoperative acute lung injury (ALI) after liver transplantation is clinically relevant and common. The perioperative thoracic fluid indices changes as well as the association with ALI in liver transplantation have not been thoroughly investigated. METHODS: A total of 52 consecutive adult recipients for elective living donor liver transplantation were enrolled. Each recipient received the same perioperative care plan. Thoracic fluid indices, including the cardiac index, intrathoracic blood volume index (ITBVI), extravascular lung water index (EVLWI), and pulmonary vascular permeability index (PVPI), were obtained at seven time points (pretransplantation, anhepatic phase, 30 minutes after reperfusion, 2 hours after reperfusion, and postoperative days 1-3) using the pulse contour cardiac output system...

OBJECTIVES: This study aimed to assess the short-term respiratory tolerance and haemodynamic efficiency of low-volume resuscitation with hypertonic saline and hydroxyethylstarch (HS/HES) in a pig model of lung contusion and controlled haemorrhagic shock. We hypothesised that a low-volume of HS/HES after haemorrhagic shock did not impact contused lungs in terms of extravascular lung water 3hours after trauma. METHODS: A lung contusion resulting from blunt chest trauma was induced in 28 anaesthetised female pigs with five bolt-shots to the right thoracic cage, followed by haemorrhagic shock and fluid resuscitation...

BACKGROUND: Heart failure is known to be a major public health problem. Fluid redistribution contributes to acute heart failure; therefore, knowledge of hemodynamic parameters could be important for optimizing outcomes. The pulse contour cardiac output monitor PiCCO uses the single thermal indicator technique and pulse contour analysis to calculate hemodynamic parameters of preload, afterload, cardiac output, systemic vascular resistance and extravascular lung water. OBJECTIVES: We primarily aimed to describe values and parameters seen in acute heart failure patients admitted to the intensive care unit (ICU) and secondly to investigate associations between hemodynamic measurements and survival data...

BACKGROUND: After lung transplantation (LT), early prediction of grade 3 pulmonary graft dysfunction (PGD) remains a research gap for clinicians. We hypothesized that it could be improved using extravascular lung water (EVLWi) and plasma biomarkers of acute lung injury. METHODS: After institutional review board approval and informed consent, consecutive LT recipients were included. Transpulmonary thermodilution-based EVLWi, plasma concentrations of epithelial (soluble receptor for advanced glycation endproducts [sRAGE]) and endothelial biomarkers (soluble intercellular adhesion molecule-1 [sICAM-1] and endocan [full-length and cleaved p14 fragment]) were obtained before and after LT (0 [H0], 6, 12, 24, 48 and 72h after pulmonary artery unclamping)...

Several studies address the accuracy of lung ultrasound (LUS) in the diagnosis of cardiogenic pulmonary edema (CPE) evaluating the interstitial syndrome, which is characterized by multiple and diffuse vertical artifacts (B-lines), and correlates with extravascular lung water. We studied the potential role of LUS in monitoring CPE response to therapy, by evaluating the clearance of interstitial syndrome within the first 24 h after Emergency Department (ED) admission. LUS was performed at arrival (T0), after 3 (T3) and 24 (T24) hours...

Positive end-expiratory pressure is one of the main parameters of respiratory support influencing the gas exchange. However, despite the number ofpositive effects, PEEP can compromise venous outflow from the cranial cavity, increased intracranial pressure, decreased venous return and cardiac output and, consequently, reduced blood pressure and cerebral perfusion. The article presents the results of a survey of 39 patients with intracranial hemorrhage in critical state, undergoing respiratory support with different levels of positive end-expiratory pressure...

Heart failure (HF) is often associated with pulmonary congestion, reduced lung function, abnormal gas exchange, and dyspnea. We tested whether pulmonary congestion is associated with expanded vascular beds or an actual increase in extravascular lung water (EVLW) and how airway caliber is affected in stable HF Subsequently we assessed the influence of an inhaled short acting beta agonist (SABA). Thirty-one HF (7F; age, 62 ± 11 years; ht. 175 ± 9 cm; wt. 91 ± 17 kg; LVEF, 28 ± 15%) and 29 controls (11F; age; 56 ± 11 years; ht...

Aquaporin 1(AQP1) and AQP5 have an important role in eliminating extravascular lung water, an increase of which contributes to lung injury in patients with sepsis and its consequent mortality. It has been reported that hydrogen-rich saline (HRS) has protective effects against sepsis-related lung injury. In this study, we hypothesized that the protective effect occurred by preserving the expression of AQP1 and AQP5. To test this hypothesis, male Sprague-Dawley rats received intratracheal administration of lipopolysaccharide (LPS) followed by intraperitoneal injection of HRS...
