Pathophysiology of fluid imbalance
Fluid imbalance can arise due to hypovolemia, normovolemia with maldistribution of fluid, and hypervolemia. Trauma is among the most frequent causes of hypovolemia, with its often profuse attendant blood loss. Another common cause is dehydration, which primarily entails loss of plasma rather than whole blood. The consequences of hypovolemia include reduction in circulating blood volume, lower v...
متن کاملAngiogenic imbalance in the pathophysiology of preeclampsia: newer insights.
Angiogenesis is the process of neovascularization from preexisting blood vessels, whereas vasculogenesis is the process of blood vessel generation from angioblast precursor cells. The human placenta undergoes high levels of angiogenesis and vasculogenesis during fetal development. Additionally, the placenta undergoes a process of vascular mimicry (also referred to as pseudovasculogenesis ) in w...
متن کاملPhysiology and pathophysiology of pleural fluid turnover
A review on pleural space is certainly most welcome, for the simple reason that on opening a textbook of physiology the concepts concerning pleural fluid turnover date back to 1927 [1]. The same comment, in fact, applies in general to microvascular water and solute exchange. This appears particularly misleading, considering the major advances achieved in the field over the last 70 yrs. Around t...
متن کاملPhysiology and pathophysiology of pleural fluid turnover.
Tight control of the volume and composition of the pleural liquid is necessary to ensure an efficient mechanical coupling between lung and chest wall. Liquid enters the pleural space through the parietal pleura down a net filtering pressure gradient. Liquid removal is provided by an absorptive pressure gradient through the visceral pleura, by lymphatic drainage through the stomas of the parieta...
متن کاملFluid and electrolyte imbalance related to intracranial abnormality
Background Maintenance of the tonicity of extracellular fluids is crucial for proper cell function. In children and adults, normal blood tonicity is maintained by a coordinated interaction among the thirst, vasopressin, and renal systems. Dysfunction in any of these systems can result in abnormal regulation of blood osmolality, which if not properly recognized and treated, may cause life-threat...
