Examples
“But in the current hyperdynamic situation, I believe we need to focus on dancing with the new, not fighting with it.”
“The contrasting effects of dopamine and norepinephrine on systemic and splanchnic oxygen utilization in hyperdynamic sepsis.”
“Generation of the hyperdynamic state is dependent on fluid repletion.”
“Inotropic Therapy in Sepsis Overview Sepsis is characterized by a hyperdynamic state, with normal-to-low blood pressure, normal-to-high cardiac index, and a low systemic vascular resistance. 1,43 Although cardiac output is usually maintained in the volume-resuscitated septic patient, a number of investigations4,125,126 have demonstrated that cardiac function is impaired.”
“Inotropic Therapy When adequately fluid resuscitated, most septic patients are hyperdynamic, but myocardial contractility, as assessed by ejection fraction, is impaired. 4 Some patients, especially those with preexisting cardiac dysfunction, may have decreased cardiac output and may require inotropic agents such as dobutamine, dopamine, and epinephrine.”
“Martin et al. 97 prospectively randomized 32 volume-resuscitated patients with hyperdynamic sepsis syndrome to receive either dopamine or norepinephrine to achieve and maintain normal hemodynamic and oxygen transport parameters for at least 6 hrs.”
“It may be used as an alternative agent in patients with hyperdynamic septic shock who require a vasopressor agent but would not benefit from a further increase in cardiac inotropic function.”
“Unfortunately, there are only a few studies evaluating the clinical use of phenylephrine in hyperdynamic sepsis.”
“In a dose-response study, phenylephrine was administered to hyperdynamic septic patients who were normotensive at the time of drug therapy. 124 In incremental doses of 0.5 to 8 µg / kg / min, phenylephrine increased MAP, systemic vascular resistance, and stroke index, while no change was seen in cardiac index.”
“Differential impairment of vascular reactivity of small pulmonary and systemic arteries in hyperdynamic sepsis.”
