BACKGROUND The purpose of this study was to validate a new level of consciousness monitor derived from the EEG, called the index of consciousness (IoC), by comparing it with the bispectral index (BIS) and the cerebral state index (CSI) during general anaesthesia for cardiac surgery using sevoflurane, remifentanil, and atracurium. METHODS After ethical committee approval and written patient co...

results seventy-five patients completed the study. compared to saline, patients who received 1 and 5 mg/kg of aminophylline demonstrated decreased extubation times (mean ± sd) (12.26 ± 7.33 vs. 11.15 ± 8.62 and 10.4 ± 4.78 min, respectively, p = 0.001) with higher bis values (p = 0.001). however, the recovery and discharge times from the pacu were no different between the aminophylline and sali...

PURPOSE To compare the depth of sedation determined by Ramsay sedation scale (RSS) with electroencephalogram-based bispectral index (BIS) and patient state index (PSI). MATERIALS AND METHODS Fifty mechanically ventilated cardiac surgical patients undergoing propofol and morphine sedation were assessed hourly for up to 6 hours or until tracheal extubation using the BIS, PSI, and RSS. Correlati...

EEG (Electroencephalography) signals can express the human awareness activities and consequently it can indicate the depth of anesthesia. On the other hand, Bispectral-index (BIS) is often used as an indicator to assess the depth of anesthesia. This study is aimed at using an advanced signal processing method to analyze EEG signals and compare them with existing BIS indexes from a commercial pr...

BACKGROUND Anesthetic administration is increasingly guided by electroencephalography (EEG)-based monitoring, such as the bispectral index (BIS). However, during cardiopulmonary bypass (CPB), factors other than the administered hypnotic agents may influence EEG signals, and their effects on BIS values are unknown. METHODS This report is a secondary analysis of data from a prospective, control...

BACKGROUND Accuracy of consciousness level assessment is very important. It may determine and influence further clinical decisions, thus influences patients' outcomes. The widest method in determining the level of awareness is the Glasgow Coma Scale (GCS). Despite its common use, GCS scores obtained by one clinician may differ from others depending on their interpretations and past experience. ...

مقدمه: bis (bispectral index) نوعی پارامتر مشتق از الکتروانسفالوگرافی (electroencephalography یا eeg) است. بی حسی اسپاینال اگر همراه با داروی سداتیو باشد سبب افت سطح هوشیاری و bis بیمار می شود. در بعضی مطالعات نشان داده شده است که در بی حسی اسپاینال حتی بدون استفاده از داروهای سداتیو، میزان هوشیاری بیمار کاهش می یابد. از جمله عواملی که روی این پارامتر تأثیر می گذارد، باریسیته است که در ارتباط ب...

مقدمه: بی حسی اسپینال روی هوشیاری و bis (bispectral index) بیمار تأثیر می گذارد. برخی مطالعات نشان داده اند بی حسی اسپینال حتی بدون داروی سداتیو باعث کاهش سطح هوشیاری می شود. در مطالعات دیگری نیز نشان داده شده است که بی حسی اپی دورال باعث کاهش عدد bis شده است. با توجه به این که تاکنون مطالعه ای برای بررسی نمره ی bis در بیماران تحت بی حسی اپی دورال حین عمل سزارین و همچنین مقایسه ی تأثیر بی حسی ا...

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 evaluated as a tool for measuring depth of anaesthesia, but the use of BIS in a paediatric population is still controversial. This study was designed to evaluate the correlation of BIS with end-tidal sevoflurane concentration and age in infants and children. METHODS Eighty-one patients undergoing elective urology surgery were allocated into three...
