conclusions although propofol remains a standard agent for such types of surgeries, lidocaine proved equally effective and coupled with its low cost, minimal side effects and omission of other hypnotic agents was a plausible induction agent and a maintenance drug in the selected cases. case presentation lidocaine was applied as the sole anaesthetic for induction and maintenance during aneurysm ...

Intracranial pressure (ICP) is one of most important factors in determining health and function of cerebroscular system. However the methods of measuring ICP are usually invasive . In an attempt to find a noninvasive method to assess ICP, in previous study web found a reverse relationships between changes in ICP and blood flow in scalp (SBF) and leg skin (LSBF) . In this study the role of sympa...

although measurement of intracranial pressure by noninvasive methods has been suggested, but mainly invasive methods are used for this purpose-increase in episcleral venous pressure can be expected to result in a linear increase in intraocular pressure. congested oculat veins with capillary leakage and hemorrhage are seen when the icp is increased, thus theoretically measurement of intraocular ...

conclusions although, the exact cause of pseudotumor cerebri in most individuals is unknown, but we should remind tuberculosis specially in endemic area for this infection. case presentation here, we presented a 14-year-old girl who referred to our hospital for fever, headache, vomiting and diplopia which has not respond to antibiotic therapy for acute meningitis. finally, with more evaluations...

Thiopentone was administered in bolus doses (1.5–3.0 mg/kg) 26 times to 18 neurosurgical patients undergoing craniotomy. Intracranial pressure and blood pressure responses to thiopentone were evaluated and the cerebral perfusion pressure calculated. Thiopentone given 21 times to treat chronic or acutely elevated intracranial pressure significantly reduced the mean pressure from 40 1.5 to 22 1.4...

The pathophysiological changes of progressive neonatal hydrocephalus include: increased intracranial volume of cerebrospinal fluid, progressive dilatation of cerebral ventricles, decreased intracranial compliance, raised intracranial pressure, alteration of cerebral circulation and subsequent secondary brain tissue damage (decreased cerebral blood flow, hypoperfusion, ischaemia), alteration of ...

Post-lumbar puncture (LP) headache may be due to "low CSF pressure", leading to stretching of pain sensitive intracranial structures. The low intracranial pressure is secondary to net loss of intracranial CSF. It has, however, not been possible to measure intracranial CSF volume accurately during life until recently. Intracranial CSF volume can now be measured non-invasively by a MRI technique....

Background and Importance: Arachnoid cysts are benign nontumoral lesions that are usually found incidentally in brain imaging. Suprasellar Arachnoid Cysts (SSACs) are rare. They can cause hydrocephalus and increased intracranial pressure, lower cranial nerve impairment and endocrine disorder. Sometimes arachnoid cysts become complicated by subdural hematoma/hygroma.  Case Presentation: We...
