In this regard, the authors noted the need for comparable future studies in terms of normovolaemia at the time of the study, sympathetic block level (including or excluding cardioaccelerator nerves), defining the developmental stage of sepsis (early or hyperdynamic, late or hypodynamic) and demonstration of a maintained sympathetic block (again the level including or excluding adrenal glands).
At approximately 16 hours, CLP-induced sepsis is marked by hypoglycemia, hypoinsulinemia, and hypodynamic circulation along with markedly increased lactate levels [13].

Conclusions: In the present study, we developed a novel porcine model of septic shock induced by ARDS due to severe MRSA pneumonia with characteristic hyperdynamic and hypodynamic phases in 24 h, which mimicked the hemodynamic changing of septic shock in human.

At the late, hypodynamic stage of sepsis (i.e., 18 hours after CLP) or sham operation, rats were anesthetized by inhaling 1-3% isoflurane and 40% oxygen.

In preliminary experiments, we observed a hyperdynamic physiological state followed by a hypodynamic physiological state, similar to hemodynamic alterations in septic patients.
This model produces a hyperdynamic, hypermetabolic state that can lead to a hypodynamic, hypometabolic stage, and eventual death.
This combination, the thinking goes, results in the inability of hypodynamic and hypovascular bone to meet increased demand for repair and remodeling, owing to the innate, continual physiologic stress (mastication), iatrogenic trauma (tooth extraction or denture injury), or dental infection within an environment laden with oral flora bacteria.
