central venous pression

PURPOSE: While intra-abdominal hypertension (IAH) has been associated with adverse outcomes in multiple settings, the epidemiology and clinical implications of IAH in the context of cardiac surgery are less known. In this study, we aimed to describe the prevalence of IAH in patients undergoing cardiac surgery and determine its association with patient characteristics and postoperative outcomes. METHODS: We conducted a single-centre prospective cohort study in which intra-abdominal pressure was measured in the operating room after general anesthesia (T1), after the surgical procedure (T2), and two hours after intensive care unit (ICU) admission (T3) in a subset of patients...

BACKGROUND: Traditionally, fluid administration during kidney transplant surgery is guided by central venous pressure (CVP) despite its limited reliability as a parameter for assessing intravascular fluid volume, particularly in patients with cardiovascular diseases. The recommended goals at graft reperfusion are a mean arterial pressure of 90 mm Hg and a CVP of 12-14 mm Hg. This approach may increase the risk of significant adverse effects due to volume overload. Perioperative fluid therapy guided by dynamic indices of fluid responsiveness has been shown to optimize intravascular volume and prevent complications associated with overzealous administration of fluids in major abdominal surgeries...

UNLABELLED: Inferior acute myocardial infarction (IAMI) is often associated with right ventricle involvement (RVAMI). Echocardiogram (Echo) shows the ischemic involvement of the right ventricle with an initial dilatation (RVD) and segmental cinetic abnormalities (RVSCS). During RVAMI the normal convexity of the interatrial septum (IAS) toward right atrium is inverted (IASI). 53 patients with IAMI were studied with ECG, echo and hemodinamic monitoring by a Swan-Ganz catheter. Echo was early performed and patients were subdivided into three groups: 1...

Central venous catheter for chronic hemodialysis can present primary or secondary dysfunctions. The first are related to malpositions or kinking, diagnosis is radiological. A postoperative chest radiography has to be done, but during the first session an initial evaluation of the catheter functioning is useful: a 'pressions test' (recording of arterial depression and venous counter-pression for progressively increasing blood flow) and recirculating test have to be performed. Later, clotting or thrombosis of catheter are often involved, detection and management are different according to the type of manifestations and to the moment of occurrence (when aspiration of residual heparin or when initiating dialysis)...
