Renal autoregulation and blood pressure management in circulatory shock
The importance of personalized blood pressure management is well recognized. Because renal pressure-flow relationships may vary among patients, understanding how renal autoregulation may influence blood pressure control is essential. However, much remains uncertain regarding the determinants of renal autoregulation in circulatory shock, including the influence of comorbidities and the effects o...
متن کاملCerebral hemodynamics, autoregulation, and blood pressure management.
INTRODUCTION Chronic hypertension may be the single most important modifiable risk factor for ischemic stroke (19). Antihypertensive therapy has been proven to reduce the risk of stroke in prospective, randomized controlled studies (7). Hypertension is common in patients presenting with acute ischemic stroke (4), but its treatment is controversial (9). In contrast to chronic hypertension, there...
متن کاملPersonalizing blood pressure management in septic shock
This review examines the available evidence for targeting a specific mean arterial pressure (MAP) in sepsis resuscitation. The clinical data suggest that targeting an MAP of 65-70 mmHg in patients with septic shock who do not have chronic hypertension is a reasonable first approximation. Whereas in patients with chronic hypertension, targeting a higher MAP of 80-85 mmHg minimizes renal injury, ...
متن کاملCerebral autoregulation and blood pressure lowering.
Despite its comparatively small size, the brain receives a disproportionate amount of blood flow compared with most other organ systems. Cerebral blood flow is closely coupled to brain metabolism and can be affected by respiratory-induced CO2 changes and arterial blood pressure. Autoregulation is the intrinsic capacity of resistance vessels in end organs, such as heart, kidney, and brain, to di...
متن کاملResetting of renal blood autoregulation during acute blood pressure reduction in hypertensive rats.
Decrease in systemic blood pressure, duration of pressure decrease, and change in the activity of the renin or the sympathetic nervous system may represent mechanisms involved in resetting the renal blood flow (RBF) autoregulation found in hypertensive rats. Autoregulation of RBF, plasma renin concentration (PRC), and the time needed for resetting to take place were studied in the nonclipped ki...
