BACKGROUND Processed electroencephalographic indices, such as the bispectral index (BIS), are potential adjuncts for assessing anesthetic depth. While BIS® monitors might aid anesthetic management, unprocessed or nonproprietary electroencephalographic data may be a rich source of information for clinicians. We hypothesized that anesthesiologists, after training in electroencephalography interpr...

BACKGROUND The Bispectral Index (BIS) has been calibrated for several general anaesthetic agents including isoflurane. Halothane is still used in paediatric anaesthesia. Compared with other volatile anaesthetics, halothane has a different receptor affinity and differing effects on the EEG. There are limited data evaluating the BIS with halothane. We set out to compare the BIS using halothane an...

the aim of this study was to assess the effect of bleaching on elution of monomers from nanofilled and microhybrid composites.80 samples (5mm diameter and 3mm thickness) of each composite were prepared. after curing, half of them were randomly polished. each group was divided into 8 subgroups and immersed in water or 10%, 20% and 30% h2o2 for 3 or 8 hours. eluted bis-gma (bis-phenol a glycidyl ...

Color stabilities of experimental composite resins based on Bis-EFMA (a novel bisphenol A [BPA]-free monomer system) with 3M ESPE FiltekTM Z250 (FZ) and A-glycidyl methacrylate (Bis-GMA) urethane dimethacrylate (UDMA) were compared. was synthesized via the reaction between 9,9-bis[4-(2-hydroxyethoxy)phenyl]fluorene 2-(methacryloyloxy)ethyl isocyanate. Experimental Bis-EFMA-, Bis-GMA-, UMDA-base...

BACKGROUND Evaluating depth of sedation in the intensive care unit (ICU) is crucial for the management of mechanically ventilated patients but can be challenging in some situations. Because the depth of hypnosis is correlated with the decrease in photomotor reflex (PMR), we suggest using pupillometric video as an automated, noninvasive, simple, and reproducible technique to evaluate the depth o...

The phthalocyanine analogue containing nonperipheral long alkyl-substituted benzenoid rings and pyridine rings, zinc bis(1,4-didecylbenzo)-bis(2,3-pyrido) porphyrazine, was synthesized. Zinc bis(1,4-didecylbenzo)-bis(2,3-pyrido) porphyrazine reacted with dimethyl sulfate and monochloroacetic acid to produce their quaternized products and diethyl sulfate to produce the sulfo-substituted products...

Regional cerebral oxygen saturation (rSO2) and the bispectral index (BIS) are used to detect cerebral perfusion abnormalities. However, whether rSO2 and BIS values change during ligation of the internal jugular vein (IJV) is unknown. We report a case in which BIS values were decreased, despite increased rSO2 during ligation of the IJV. A 72-year-old man was diagnosed with metastasis of renal ca...

We report a case of an erroneously elevated bispectral index (BIS) during robot assisted thyroidectomy using an electromyographic endotracheal tube (EMG tube), which is safe and useful for laryngeal electromyographic monitoring. Ten minutes after start of the operation, a sudden increase of BIS value up to 98 was noticed. The BIS values were not decreased to < 65 with supplemental anesthetics. ...

Today, business intelligence system (BIS) is universally considered as an essential tool to aid business decision making process. There is consensus that BIS has significant effects on predicting current and prospective views of business operations. These effects will only be realized if, and when, BIS are widely spread and used. An imperative study of BIS adoption theories is crucial in order ...
