We studied the effects of nifedipine, chlorpromazine, reserpine, furosemide, and thiopental on the mean arterial blood pressure, mean intracranial pressure, and cerebral perfusion pressure in 38 patients with increased intracranial pressure resulting from either hemorrhagic cerebrovascular disease or systemic hypertension. These agents are widely used in neurosurgical practice for the treatment...
Since without prospective randomized studies it is not possible to have a clear attitude towards the importance of intracranial pressure monitoring, this study was aimed at examining the prognostic effect of the intracranial pressure monitoring and intracranial pressure oriented therapy in severe brain trauma patients, and at defining optimal intracranial pressure values for starting the treatm...
purpose: to report a case of spinal cord tumor with visual symptoms and papilledema due to increased intracranial pressure. patient and findings: a 24-year-old woman was referred because of recent blurred vision in both eyes. visual acuity was 20/25 and 20/20 in the right and left eyes, respectively. fundoscopy revealed bilateral papilledema. other ophthalmic examinations were normal. visual fi...
OBJECTIVE To assess the impact of intracranial pressure monitoring on the short-term outcomes of traumatic brain injury patients. METHODS Retrospective observational study including 299 consecutive patients admitted due to traumatic brain injury from January 2011 through July 2012 at a Level 1 trauma center in São Paulo, Brazil. Patients were categorized in two groups according to the measure...
OBJECTIVE To determine whether there was a correlation between tonometric measurements of the intraocular pressure and transducer measurements of the intracranial pressure in the acute setting, and whether intraocular pressure can be used as a surrogate measure of intracranial pressure. Children with traumatic brain injuries commonly develop increased intracranial pressure requiring surgical pl...
Elevation of intrathoracic pressure during cardiopulmonary resuscitation generates carotid pressure and flow, but also increases intracranial pressure. This increase in intracranial pressure may limit cerebral blood flow. Therefore, we performed studies designed to quantify the extent of this transmission and to identify the mechanism of transmission of intrathoracic pressure to the intracrania...
Background: In previous studies, the neuroprotective effect of 17&beta-estradiol in diffuse traumatic brain injury has been shown. This study used ICI 182,780, a non-selective estrogen receptor antagonist, to test the hypothesis that the neuroprotective effect of 17&beta-estradiol in traumatic brain injury is mediated by the estrogen receptors. Methods: The ovariectomized rats were divided into...
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 ...
