Cerebral haemodynamics during experimental intracranial hypertension.
Intracranial hypertension is a common final pathway in many acute neurological conditions. However, the cerebral haemodynamic response to acute intracranial hypertension is poorly understood. We assessed cerebral haemodynamics (arterial blood pressure, intracranial pressure, laser Doppler flowmetry, basilar artery Doppler flow velocity, and vascular wall tension) in 27 basilar artery-dependent ...
متن کاملIntracranial hypertension in Africans with cerebral malaria.
The causes of death and neurological sequelae in African children with cerebral malaria are obscure. Intracranial pressure (ICP) was monitored and cerebral perfusion pressure (CPP) calculated in 23 Kenyan children with cerebral malaria. Four children had severe intracranial hypertension (ICP > 40 mm Hg, CPP < 40 mm Hg): two died, one with an ICP of 158 mm Hg and signs of transtentorial herniati...
متن کاملHaemodynamics in essential hypertension
The arterial blood pressure is mainly determined by the cardiac output and the total peripheral resistance. The blood pressure and the cardiac output are measured and the total peripheral resistance is calculated by dividing mean arterial blood pressure by cardiac output. This calculation is valid only for laminar flow in rigid straight tubes, but still this calculation is currently used to est...
متن کاملCerebral venous etiology of intracranial hypertension and differentiation from idiopathic intracranial hypertension.
This study presents the characteristics that distinguish between idiopathic intracranial hypertension (ICH) and ICH caused by intracranial vascular damage. Twenty-one patients with ICH were included in this study. The analysis of the symptomatology correlated with the values of intracranial pressure, and the imaging findings revealed significant differences between these two types of ICH. ICH c...
متن کاملCerebral haemodynamics and carbon dioxide reactivity during sepsis syndrome
BACKGROUND Most patients with sepsis develop potentially irreversible cerebral dysfunctions. It is yet not clear whether cerebral haemodynamics are altered in these sepsis patients at all, and to what extent. We hypothesized that cerebral haemodynamics and carbon dioxide reactivity would be impaired in patients with sepsis syndrome and pathological electroencephalogram patterns. METHODS After...
