Interethnic differences in debrisoquin and mephenytoin hydroxylation have been compared between normal white (n = 183) and Japanese (n = 100) subjects with the 8-hour urinary metabolic ratio of debrisoquin and the urinary S/R enantiomeric ratio of mephenytoin to identify extensive (EM) and poor (PM) metabolizers. In white subjects the frequency of PMs was(More)
Central nervous system complications continue to be major causes of morbidity and mortality after cardiac surgery. The purpose of this study was to identify the risk factors for postoperative cognitive dysfunction after coronary artery bypass graft (CABG) surgery. Eighty-eight patients scheduled for elective CABG were studied. After the induction of(More)
Propofol is commonly used for anesthesia and sedation in intensive care units. Approximately 53% of injected propofol is excreted in the urine as the glucuronide and 38% as hydroxylated metabolites. Liver, kidneys and intestine are suspected as clearance tissues. We investigated the contribution of the liver and kidneys to propofol metabolism in humans(More)
We report a unilateral hypoglossal nerve paralysis following the use of a laryngeal mask airway in a 62-year-old woman with rheumatoid arthritis undergoing a shoulder joint replacement. Cervical epidural anaesthesia was combined with general anaesthesia using nitrous oxide administered via a laryngeal mask airway with the patient in the right lateral(More)
BACKGROUND Propofol is used during living-related donor liver transplantation because its metabolism is not greatly affected by liver failure. However, the pharmacokinetics of propofol during liver transplantation have not been fully defined. The purpose of this study was to evaluate the apparent systemic clearance of propofol during the dissection,(More)
BACKGROUND AND PURPOSE The purpose of this study was to examine the effects of diabetes mellitus and its severity on the cerebral vasodilatory response to hypercapnia. METHODS Thirty diabetic patients consecutively scheduled for elective major surgery were studied. After induction of anesthesia, a 2.5-MHz pulsed transcranial Doppler probe was attached to(More)
We describe a new method for radio-frequency mandibular nerve rhizotomy under CT fluoroscopy. A patient with cancer had severe intractable and drug-resistant pain in his left mandibular region. Because he had an anatomic deformity due to cancer invasion and radiation therapy, we planned a mandibular nerve rhizotomy under CT fluoroscopic imaging. The needle(More)
In 236 consecutive lumbar epidural anesthesia patients, epidurography was performed in seven patients who developed unilateral loss of cold sensation to clarify the cause of unilateral block. Epidurography demonstrated the epidural catheter tip location in the anterior epidural space in four patients (57%) and in the transforaminal passage in three patients(More)
The aim of the present study was to compare the influence of volatile anesthetics on transcranial motor-evoked potentials (tcMEP) in humans anesthetized with propofol/fentanyl/nitrous oxide and on partial neuromuscular blockade (NMB). The authors studied 35 ASA I and II patients who were undergoing elective craniotomy and brain tumor resection. The patients(More)
The present study was conducted to elucidate the role of activin A in capillary formation. When bovine aortic endothelial cells (BAEC) were cultured in a collagen gel, basic fibroblast growth factor (FGF-2) induced tube formation. Activin A also induced tube formation and the addition of two factors together was more effective. BAEC produced both FGF-2 and(More)
