The cerebral microcirculation is protected during experimental hemorrhagic shock.
OBJECTIVE Decreases in buccal microcirculation are indicative of the severity of hemorrhage, but incidental observations suggest that this may not apply to the cerebral microcirculation. We therefore hypothesized that the cerebral microcirculation may be preserved in hemorrhagic shock in which systemic and buccal microcirculatory flow are reduced. We propose to relate changes in the macrocircul...
متن کاملHemorrhagic shock hemodynamic and metabolic behavior: experimental study in dogs.
BACKGROUND AND OBJECTIVES Different experimental models have been used to illustrate hemodynamic and metabolic changes during hemorrhagic shock. This study aimed at observing hemodynamic and metabolic behaviors during a sequential and progressive model of hemorrhagic shock in dogs to determine which indices are earlier changed. METHODS The study involved 13 dogs under total intravenous anesth...
متن کاملChanges in Left Ventricular Global and Regional Longitudinal Strain During Right Ventricular Pacing
BACKGROUND Our study aimed to demonstrate the short-term impacts of right ventricular apical pacing (RVAP) and right ventricular septal pacing (RVSP) on left ventricular (LV) regional longitudinal strain (RLS) and global longitudinal strain (GLS) in patients with preserved ejection fraction (EF). LV strain and functions may be altered by RVAP. RVSP might be a better alternative. The detrimental...
متن کاملExperimental models of hemorrhagic shock: a review.
Massive blood loss leading to hypovolemic shock is still a life-threatening situation. Recently, a great number of investigations have been conducted in order to understand the pathophysiological and immunological changes taking place during shock and to develop treatment strategies. These preclinical trials are based on animal studies. Although a wide spectrum of species and experimental model...
متن کامل[Hemodynamics in hemorrhagic infarction--an experimental study].
Using our previously reported "thalamic infarction model in the dogs", it was found that hemorrhagic infarction can be produced at a high frequency following recirculation after 6-12 hours of vascular occlusion. In the present study, in order to elucidate the pathophysiology of hemorrhagic infarction, we have undertaken a study of the relations among the histological findings, degree of ischemi...
