Venous Congestion and Organ Dysfunction.

Venous CongestionOrgan Dysfunction Syndrome

Venous congestion, which is a phenomenon described in cardiology and post-operative cardiac surgery, is responsible for an increase in morbidity and mortality. Indeed, it can lead to kidney failure, liver failure, prolonged ileus, scarring complications, and neurological disorders. Clinical and ultrasound indications have been described to diagnose this condition. To date, this phenomenon is poorly known and not described in intensive care patients outside the cardiac context. However, intensive care patients can present the risk factors associated with the occurrence of congestion: acute cardiac failure, significant water-salt overload, and/or fluid distribution anomalies. Thus, observational studies have found an association between the input-output balance, the quantity of salt-water intake, the presence of right heart dysfunction and the occurrence of acute kidney failure, digestive disorders, hypoxemia and a prolonged stay in intensive care. The presence of a congestive condition is medically treatable since diuretic decongestion is associated with improved cardiac outcomes. It is therefore necessary, in an intensive care context, to be able to define and diagnose this state of venous congestion, to study its prevalence, and to confirm the existence of a link with organ failure in order to pave the way to known adapted treatment options.

PORH and Response to Cold in Raynaud's Phenomenon.

Raynaud DiseaseHyperemia1 more

The main objective of the study is to determine if implication of epoxy-eicosatriénoïc acids (EETs) and NO during cutaneous post-occlusive hyperemia differs between patients with Raynaud phenomena and healthy volunteers, by studying hyperaemic postocclusive response after microinjection of fluconazole and L-NMMA at the dorsal side of the fingers.

Characterization of Endothelial Dysfunction as a Function of Hyperaemia of the Brachial Artery During...

Capillary Leak Syndrome

The glycocalyx is a layer of proteins and complex sugars covering the endothelium of vessels. Its role as capillary filtration control is important. In case of alteration of the glycocalyx, experimental models and some clinical studies show an increased capillary leak responsible for interstitial edema. The analysis of glycocalyx in routine care is important to guide volume expansion. Indeed, the literature provides evidence about the poor prognosis of excess water and its impact on organ. This analysis challenge is to justify filling solution of choice according to the characteristic of this capillary leakage.

Venous Congestion and Acute Renal Failure in Cardiac Surgery Postoperative

Acute Renal Failure (ARF)

Acute renal failure (ARF) is a frequent complication in the postoperative cardiac surgery, and is a major risk factor for mortality in this context. The right ventricular dysfunction post cardiopulmonary bypass (CPB) is also a common complication, close to 100% if one takes into account the transient dysfunction. A recent study showed that right ventricular dysfunction and the IRA seemed related, rather on the slope of venous congestion. We wish to study this phenomenon more specifically in particular to offer reliable diagnostic markers of venous congestion.
