BACKGROUND Intracranial pressure elevation, peaking three to seven post-stroke is well recognized following large strokes. Data following small-moderate stroke are limited. Therapeutic hypothermia improves outcome after cardiac arrest, is strongly neuroprotective in experimental stroke, and is under clinical trial in stroke. Hypothermia lowers elevated intracranial pressure; however, rebound in...

background :there is not any data available about the effect of high bar pressure condition on intracranial pressure. in this study, the effect of diving on the optic nerve and sheath diameters as non-invasive markers of intracranial pressure has been investigated.   methods : twenty professional male divers from twenty one volunteers were chosen for this cross-sectional study. only one person ...

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...

Intracranial pressure is normally transmitted to the perilymph of the cochlea via the cochlear aqueduct. The relationship between perilymphatic pressure, indirectly measured by tympanic membrane displacement, and mean intracranial pressure defined either clinically or by direct measurement has been examined in 58 patients (aged 5-77 years), with hydrocephalus, benign intracranial hypertension, ...

This study applied multiscale entropy analysis to investigate the correlation between the complexity of intracranial pressure waveform and outcome after traumatic brain injury. Intracranial pressure and arterial blood pressure waveforms were low-pass filtered to remove the respiratory and pulse components and then processed using a multiscale entropy algorithm to produce a complexity index. We ...

BACKGROUND Intracranial hypertension due to primary and secondary injuries is a prime concern when providing care to patients with severe traumatic brain injury. Increases in intracranial pressure vary depending on compensatory processes within the craniospinal space, also referred to as intracranial adaptive capacity. In patients with traumatic brain injury and decreased intracranial adaptive ...

OBJECTIVES Randomized trials have suggested that hypertonic saline solutions may be superior to mannitol for the treatment of elevated intracranial pressure, but their impact on clinical practice has been limited, partly by their small size. We therefore combined their findings in a meta-analysis. DATA SOURCES We searched for relevant studies in MEDLINE, EMBASE, the Cochrane Central Register ...

The intravenous administration of Althesin 50 /d/kg to 9 patients undergoing neurosurgery during general anaesthesia with controlled ventilation resulted in a fall in intracranial pressure (i.c.p.) measured in one lateral ventricle. The extent of the reduction in intracranial pressure was directly proportional to the starting value of pressure. Intracranial pressure gradually returned to contro...
