We investigated the relationship between electroencephalogram (EEG) activity and autonomic nervous system function using spectral analyses of EEG and heart rate variability (HRV) in healthy subjects during sleep. Eleven subjects were enrolled in this study. From EEG, the spectral edge frequencies (SEFs including SEF50, SEF90 and SEF95) were calculated. From(More)
Mitochondrial disease has been uncommon conditions, still results in death during childhood in many cases. The ideal anesthetic pharmacological management strategy for adult patients with mitochondrial disease is currently unclear. In this study, we presented features of the anesthesia methods employed and the perioperative complications of patients in our(More)
BACKGROUND AND AIM The aim of the present study was to evaluate the efficacy and safety of sedation with a combination of propofol (PF) and dexmedetomidine (DEX) compared with sedation with benzodiazepines in esophageal endoscopic submucosal dissection (ESD). METHODS We retrospectively reviewed clinical data for 40 consecutive patients who had undergone(More)
In isolated area in Japan, only one anesthesiologist must often do new anesthetic techniques such as ultrasound-guided procedures without receiving any teaching. One solution to this problem may involve teleanesthesia, by which experienced anesthesiologists teach novices in remote places, by utilizing information communicatioin technologies. FaceTime™(More)
BACKGROUND During sedation for upper gastrointestinal endoscopy, oxygen delivery via a nasal cannula is often necessary. However, the influences of the oxygen delivery route and breathing pattern on the F(IO2) have not been thoroughly investigated. The aim of this simulation study was to investigate the difference in the F(IO2) with a pharyngeal cannula(More)
We examined fish community structures in floodplain backwaters in the Kiso River, Central Japan, in an uncommon drought year. Nine floodplain backwaters with varying levels of flood inundation frequency were surveyed for winter fish communities, and measured for local environmental variables in summer and winter periods. The winter fish community was better(More)
BACKGROUND Studies have compared sealing effects of the newly developed tapered endotracheal tube cuff with the conventional cylindrical cuff. In this study, we compared the difference between cuffs with regard to the increase in intracuff pressure during nitrous oxide (N(2)O) exposure. METHODS Two types of cuffs were studied using a model trachea(More)
We present the management of a 15-year-old girl with acute myeloid leukemia who presented with massive hyperleukocytosis and neurological deficit due to intracerebral hemorrhage. Surgical intervention was considered but ultimately not undertaken because of the presence of massive hyperleukocytosis, thrombocytopenia, hypokalemia, and considerable discrepancy(More)
STUDY OBJECTIVE The glass vial of acetaminophen as an intravenous preparation (Acelio®, Terumo, Japan) has a strong internal negative pressure. The aim of our study was to determine if this negative pressure could result in medication administration errors if not released prior to connecting to the IV set. DESIGN Questionnaire survey and simulation study.(More)
BACKGROUND In surgical repair of abdominal aortic aneurysm (AAA), excessive bleeding which causes postoperative complications is sometimes observed. To determine the risk factors of perioperative excessive blood loss, this retrospective study was performed. METHODS Design. A retrospective study. Setting. An academic medical center. Participants.
