Bleeding from the hepatic vein is closely related to central venous pressure (CVP). To evaluate the effect of low central venous pressure during a hepatectomy, the infrahepatic inferior vena cava (IVC) was half clamped. Between 2006 and 2007, 20 patients undergoing major hepatectomy with the IVC half clamping (half-clamping group) were compared with 58(More)
The present study examined the modulator role of the phosphatidylinositol 3-kinase (PI3K)-Akt pathway activated by the alpha-1 adrenoceptor agonist phenylephrine in ATP-sensitive K(+) channel function in intact vascular smooth muscle. We evaluated the ATP-sensitive K(+) channel function and the activity of the PI3K-Akt pathway in the rat thoracic aorta(More)
BACKGROUND Vascular dysfunction induced by hyperglycemia has not been studied in cerebral parenchymal circulation. The current study was designed to examine whether high glucose impairs dilation of cerebral parenchymal arterioles via nitric oxide synthase, and whether propofol recovers this vasodilation by reducing superoxide levels in the brain. METHODS(More)
BACKGROUND It is not known whether thromboxane A2 impairs adenosine triphosphate (ATP)-sensitive K channel function via increased production of superoxide in blood vessels and whether propofol as a nicotinamide adenine dinucleotide phosphate (NADPH) oxidase inhibitor restores this modification. METHODS Rat aortas without endothelium were used for(More)
BACKGROUND An acetylcholinesterase inhibitor donepezil currently is used to treat patients with Alzheimer disease. However, its direct effect on cerebral blood vessels has not been evaluated. The present study was designed to examine whether donepezil induces acute cerebral arteriolar dilation and whether neuronal nitric oxide synthase contributes to this(More)
We report a 49-year-old woman with intravenous and intracardiac extension of uterine leiomyomatosis. After subtotal hysterectomy and salpingo-oophorectomy, an intravenous and intracardiac tumor was removed under normothermic cardiopulmonary bypass without cardiac arrest. Postoperatively, occlusion of the artery supplying the remaining uterine cervical stump(More)
The purpose of this study was to conduct a survey of emergency or complication during sedation and change of attitude toward sedation by simulation-based sedation training course (SEDTC) hosted by the Japanese Association of Medical Simulation. We used a questionnaire survey to non-anesthesiologists who participated in the 1st to 13th SEDTCs from 2011 to(More)
Participation in the American Heart Association advanced cardiac life support provider course is a prerequisite for taking the anesthesiology specialist examination in Japan. The course teaches fundamental resuscitation methods for different types of cardiac arrest. However, crisis in the perioperative period can result from airway trouble, central venous(More)
PURPOSE Recent guidelines for cardiopulmonary resuscitation emphasize that all rescuers should minimize the interruption of chest compressions, even for intravenous access. We assessed the utility of needle guides during ultrasound-guided central venous catheterization (US-CVC) with chest compressions via simulation. METHODS Twenty-five anesthesiologists(More)
