Raised intracranial pressure and cerebral blood flow. 4. Intracranial pressure gradients and regional cerebral blood flow.
Intracranial pressure was raised by expansion of a supratentorial subdural ballon in anaesthetized baboons. Pressures were measured at several sites, both supratentorial and infratentorial, and cerebral blood flow was measured in each cerebral hemisphere separately. Pressures recorded from the right and left lateral ventricles corresponded closely throughout. Highly significant correlations wer...

متن کاملEffect of systemic arterial blood pressure on cerebral blood flow in intracranial hypertension.
In five baboons and 11 cats cerebral ischaemia was produced either by inflating an epidural balloon and or by ligating major arteries supplying the brain. Fifteen of the animals developed intracranial hypertension after cerebral ischaemia. If ICP were high, but still significantly lower than MABP, elevation of MABP by noradrenaline infusions was accompanied by a proportional increase of ICP. Ho...
متن کاملCerebral Blood Flow and Intracranial Pressure
Update in Anaesthesia | www.worldanaesthesia.org CEREBRAl BlooD FloW The brain is unusual in that it is only able to withstand very short periods of lack of blood supply (ischaemia). This is because neurones produce energy (ATP) almost entirely by oxidative metabolism of substrates including glucose and ketone bodies, with very limited capacity for anaerobic metabolism. Without oxygen, energyde...
متن کاملEffects of hyperbaric oxygen on intracranial pressure and cerebral blood flow in experimental cerebral oedema.
Increased intracranial pressure was induced in anaesthetized dogs by application of liquid nitrogen to the dura mater. Intracranial pressure and cerebral blood flow were measured, together with arterial blood pressure and arterial and cerebral venous blood gases.Carbon dioxide was administered intermittently to test the responsiveness of the cerebral circulation, and hyperbaric oxygen was deliv...
