The primary objective of this study was to evaluate the electrophysiologic effects of large-dose propofol, used as the sole anesthetic in patients with epilepsy. Nine patients with medically intractable complex partial epilepsy undergoing a three-stage approach to the surgical management of epilepsy were recruited. State I involved placement of the(More)
OBJECTIVE To survey a large number of neurosurgical spine surgeons for data regarding the presence of risk factors in patients experiencing visual loss after spine surgery. METHODS A survey was sent to current members (as of 1997) of the American Association of Neurological Surgeons/Congress of Neurological Surgeons, Section on Disorders of the Spine and(More)
Blood temperature at the jugular bulb was monitored in 10 patients undergoing neurovascular procedures that used induced mild hypothermia, and its correlation with surface brain, core, and peripheral temperatures was determined. The study was motivated by the difficulty encountered in directly measuring global brain temperature and the poor correlations(More)
Hypothermia for cerebral protection is usually achieved by administration of intravenous fluids at room temperature, cooling ambient air, ice packs, and a temperature-adjustable circulating water mattress. We compared cooling by conduction by using a water mattress to cool by convection by using a forced-air cooling device. Twenty patients were(More)
Midazolam and sufentanil are commonly used for sedation. Cerebrovascular effects of low-dose midazolam have not been studied previously, and cerebrovascular effects of sufentanil remain controversial. Forty ASA I and II patients were studied preoperatively. These patients were given midazolam (20 or 40 micrograms/kg) or sufentanil (0.1 or 0.2 micrograms/kg)(More)

Estrogen and estrogen receptor (ER)-mediated signaling pathways play important roles in the etiology and progression of human breast, endometrial, and ovarian cancers. Attenuating ER activities by natural products and their derivatives is a relatively practical strategy to control and reduce breast, endometrial, and ovarian cancer risk. Here, we found(More)
Indications for carotid endarterectomy (CEA) have been expanded recently, and a consensus statement has been made regarding these changes. However, the debate regarding the "ideal" anesthetic for CEA remains on-going. This study was designed to evaluate the actual anesthetic techniques used by anesthesiologists for CEA. A total of 426 1-page questionnaires(More)
