The Surviving Sepsis Campaign targets central venous pressure, mean arterial pressure, and central venous oxygen saturation as guides for resuscitation. Fluid resuscitation and the use of vasopressors are paramount to the success of the campaign's end points. Although the achievement of supranormal physiologic parameters has been associated with higher mortality in some studies, these slightly ...

Hemodynamic parameters were studied before and after rapid dextran infusion in 34 men including 17 patients with sustained essential hypertension and 17 normotensive controls. In both groups of patients, dextran infusion induced a significant increase (p less than 0.001) in central venous pressure (CVP), cardiac output (CO), and stroke volume. The percent change in stroke volume was significant...

AIM OF THE STUDY Information on central venous pressure (CVP) is helpful in clinical situations like cardiac failure and sepsis. Compression ultrasound (CU) of a forearm vein has been shown to be a reliable method for CVP measurement when assessed by experienced personal under study conditions. To test the hypothesis, that CU can be reliably used for CVP measurement after a training program and...

The physiological limitations of the Fontan circulation have been extensively addressed in the literature. Many studies emphasized the importance of pulmonary vascular resistance in determining cardiac output (CO) but gave little attention to other cardiovascular properties that may play considerable roles as well. The present study was aimed to systemically investigate the effects of various c...

BACKGROUND During the perioperative period an adequate intravascular volume must be maintained. Current recommendations overestimate perioperative volume requirements. AIM To compare perioperative volume administration using standard monitoring methods or guided by left ventricular filling parameters. MATERIAL AND METHODS Twenty-four patients subjected to colon resection were randomized to ...

Material and Resources A descriptive, retrospective study. We describe the results of a small series of potential donors (including older than 70 years) treated in single tertiary level center, from January to September 2013, in accordance with a strict protocol of protective ventilation, recruitment maneuvers, postural changes and negative fluid balance. The collected variables were: Ventilato...

Abdominal counterpulsation added to standard cardiopulmonary resuscitation improves blood flow in animal models when compared to chest compressions alone. Similar effects can be demonstrated in analog and digital computer models of the circulation. The technique generates both central aortic and central venous pressure pulses, and successful application of the method depends on maximizing the f...

Guidelines can influence physicians to act against their better judgement. For example, while only 47% of surveyed intensivists believed that central venous pressure should guide resuscitation, 86% used it because of the SSC recommendation [2]. Protocols may improve care, but what should one do when audited patient outcomes are already better than those achieved by guideline interventions – suc...

The central venous pressure (CVP) is the most frequently used variable to guide fluid resuscitation in critically ill patients, although its use has been challenged. In this viewpoint, we use a question and answer format to highlight the potential advantages and limitations of using CVP measurements to guide fluid resuscitation.
