Active clinical trials for "Pulmonary Edema"

Whole blood sample procurement study from pregnant women with signs and symptoms of Preeclampsia.

The purpose of this study is to define the current treatment of patients ospitalized with acute cardiogenic pulmonary edema. Clinical and laboratory data collected in the Emergency Department will used to investigate the primary outcome (mortality) and risk factors related to the primary outcome.

We use a new technology (Nexfin from BMEYE-Inventive Hemodynamics) to monitor Cardiac Output, Blood Pressure, Fluid Responsiveness, Pulse Oximetry, Hemoglobin Concentration, Oxygen Delivery in Climbers during their process of acclimatization on a expedition to Mount Aconcagua.

Burn injury leads to hypovolemic then distributive shock. Fluid resuscitation remains the cornerstone of initial treatment of burn shock. However, fluid rescucitation can lead to fluid overload, which manifests most notably as lung edema. The peptide NT-pro-BNP, a biomarker of cardiac congestion secreted by the myocardium, as well as plasma CD146, an endothelial factor involved in angiogenesis and a marker of vascular congestion, may help identifying patients with risk of pulmonary edema and hypoxia . Our hypothesis is that these biomarkers may predict the occurence of pulmonary edema in severe burns patients.

Pulmonary edema can be classified into "cardiogenic pulmonary edema" and "non-cardiogenic pulmonary edema" according to the underlying etiology. Cardiogenic pulmonary edema is caused by the dysfunction in the cardiac pumping capability, leading to the transudation accumulation in the pulmonary peri-capillary space. The predisposing factors of non-cardiogenic pulmonary edema are numerous, including severe infection, renal failure, auto-immun reaction, etc. The mortality rate of pulmonary edema is relatively high, especially the non-cardiogenic one. To distinguish the type of pulmonary edema at the early stage is important for its treatment. Lung sound analysis via stethoscope is a simple diagnostic method to lung diseases clinically. Among many kinds of lung sounds, the "crackle" and "rale" are frequently found in pulmonary edema. "Rale" is also called "moist rale". It is considered as low-frequency wheezes and is often seen in cardiogenic pulmonary edema. On the other hand, "crackle" is also called "dry rale", which is a kind of high-frequency wheezes and usually seen in Acute Respiratory Distress Syndrome (ARDS) that is classified into non-cardiogenic pulmonary edema. This proposed project intends to establish a digital diagnostic method for pulmonary edema. The lung sound of patient with pulmonary edema will be collected by the lung sound acquisition system. By identifying the significant spectrum characteristics of cardiogenic pulmonary edema and non-cardiogenic pulmonary edema, the diagnostic system might be established.

The aim of the work is to Assess the incidence of weaning induced pulmonary adema(WIPO). Assess the risk factors of WIPO. Evaluate the role of lung ultrasound in detecting WIPO during spontenous breathing trial(SBT). Detect the threshold of B-line increase (Delta-B-lines) that provided the best diagnostic accuracy of WIPO.
