background: to determine if the glidescope® videolaryngoscope (gvl) could attenuate the hemodynamic responses to orotracheal intubation compared with conventional macintosh laryngoscope. objectives: the aim of this relatively large randomized trial was to compare the hemodynamic stress responses during laryngoscopy and tracheal intubation using gvl versus mcl amongst healthy adult individuals r...

OBJECTIVES Hemodynamic changes in the cerebral circulation in presence of coarctation of aorta (CoA) and their significance in the increased intracranial aneurysms (IAs) formation in these patients remain unclear. In the present study, we measured the flow-rate waveforms in the cerebral arteries of a patient with CoA, followed by an analysis of different hemodynamic indices in a coexisting IA. ...

context despite advancements in the science of surgery, minimizing bleeding from parenchymal tissue of the liver continues to be one of the challenges surgeons are facing to protect patients’ lives. however, the number of surgeries needing incisions in the liver tissue, e.g. metastatectomy, is constantly increasing. conclusions the excessive blood loss and the long time needed to control the bl...

Why we have to measure cardiac output (CO), in selected high risk surgical patients? Because fluid test can be negative and further FC has to be avoided. This is mandatory and in thoracic anesthesia with the thorax open, the anesthetist cannot use hemodynamic dynamic indices (4, 5). Only a CO (or simply the stroke volume) measurement can help you to understand if the patient is a fluid responde...

BACKGROUND AND PURPOSE We recently described an image analysis technique based on the temporal correlation mapping (TCM) of injected contrast agents that can be used to distinguish the hemodynamic core and hemodynamic penumbra after focal ischemia. In this study we used this technique for the first time to investigate the effects of the water-soluble AMPA receptor antagonist YM872 in permanent ...

OBJECTIVE Pulse pressure (PP), a strong predictor of cardiovascular events in type 2 diabetes, is a composite measure affected by several hemodynamic factors. Little is known about the hemodynamic determinants of central PP in type 2 diabetes or whether abnormalities in central pulsatile hemodynamics are already present in individuals with impaired fasting glucose (IFG). In a population-based s...

INTRODUCTION Non-invasive, continuous hemodynamic monitoring is entering the clinical arena. The primary objective of this study was to test the feasibility of such monitoring in a pilot sample of Emergency Department (ED) stroke patients. Secondary objectives included analysis of hemodynamic variability and correlation of continuous blood pressure measurements with standard measurements. MET...

The success of propranolol in treating the symptoms of angina pectoris has raised questions about the effects of beta-adrenergic blockade on the hemodynamic functions, myocardial mechanics, energetics, and metabolic functions. Five milligrams of propranolol was given intravenously to 27 human subjects, 18 with and nine without angiographically proven coronary atherosclerosis. The drug produced ...
