PURPOSE Cerebral desaturation occurs frequently in patients undergoing one-lung ventilation for thoracic surgery. The mechanism of this desaturation is unclear regarding its etiology. The objective of this study was to investigate whether or not decreases in cerebral oxygen saturation associated with one-lung ventilation were a consequence of decreased cardiac output. METHODS A blinded observ...

Background: This is a case study of 70 cases admitted in our hospital post covid-19 infection with different complaints and signs symptoms indicating Rhino-Orbital-Cerebral-mucormycosis (ROCM). Materials Methods: All the were again screened for COVID infections comorbidities like Diabetes mellitus, Hypertension or any other immunocompromised state. The level involvement nasal cavity, septum, tu...

Body Weight, Cerebral A therosclerosis and Cerebral Vascular Disease: An Autopsy Study • The severity of atherosclerotic involvement of intracranial cerebral arteries was assessed at autopsy in 3,315 adult subjects. Ponderal index values were calculated for each sex and ten-year age group. In most age groups, subjects with cerebral vascular disease, or one or more of several conditions known to...

BACKGROUND It has been suggested that a moving correlation index between mean arterial blood pressure and intracranial pressure, called PRx, can be used to monitor and quantify cerebral vasomotor reactivity in patients with head injury. OBJECTIVES To validate this index and study its relation with cerebral blood flow velocity and cerebral autoregulation; and to identify variables associated w...

BACKGROUND AND PURPOSE Impairment of cerebrovascular autoregulation may promote secondary brain injury in acute brain insults. Until now, only limited data are available on autoregulation in patients with spontaneous intracerebral hemorrhage. In the current study, we aimed to investigate cerebrovascular reactivity and its significance for outcome in spontaneous intracerebral hemorrhage. METHO...

BACKGROUND Neuropsychological dysfunction is a major cause of morbidity and mortality after cardiac surgery. AIM To evaluate if intraoperative cerebral desaturation and depth of anesthesia measured by bispectral index are related to postoperative cognitive dysfunction in cardiac surgery. MATERIAL AND METHODS Prospective study in patients undergoing elective cardiac surgery with cardiopulmon...

BACKGROUND AND PURPOSE External counterpulsation (ECP) is a novel noninvasive method used to improve the perfusion of vital organs, which may benefit ischemic stroke patients. We hypothesized that ECP may augment cerebral blood flow of ischemic stroke patients via induced hypertension. METHODS We recruited ischemic stroke patients with cerebral intracranial large artery occlusive disease and ...

cognitive impairment may be a common even at the onset of multiple sclerosis (ms). in this case-control study, we tried to find out the probable relationship between homocysteine levels and cerebral atrophy or cognitive impairment in patients with multiple sclerosis. one hundred fifty six patients who had ms according to mcdonald diagnostic criteria were included in this study. patients’ age, g...

BACKGROUND The purpose of this study was to validate a new level of consciousness monitor derived from the EEG, called the index of consciousness (IoC), by comparing it with the bispectral index (BIS) and the cerebral state index (CSI) during general anaesthesia for cardiac surgery using sevoflurane, remifentanil, and atracurium. METHODS After ethical committee approval and written patient co...
