An acceptable depth of hypnosis reading ranges between 40-60, which can serve as a good reference for anaesthetic dosing, giving a good hemodynamic stability and faster exit from anaesthesia. A general content review … It is believed that there is a relationship between the BIS and responsiveness. BIS values range from 100 (awake patient) to 0 (flat EEG). Simoncelli. Health Canada has licensed 2 consciousness monitors: the Bispectral Index (BIS) monitor and the SNAP EEG monitor system. Using Spearman's rank correlation of Comfort versus mean BIS, the correlation coefficient was r=0.92.

The range 100-86 reflects awakeness, between 85-66 means sedation, 65 to 41 value The BIS value is constantly maintained ranged from 40 to 60 during gen-eral anesthesia through the titration of anesthetic agents [10]. The bispectral index (BIS) is a multifactorial parameter derived from the electroencephalogram (EEG) that allows monitoring of the hypnotic component of anesthesia 1. The bispectral index (BIS) offers a potential alternative to subjective scales when they do not work well or may not be sufficiently sensitive to evaluate sedation level. The relationship between SAS, RASS and MASS was direct, whereas these were related inversely to RAMSAY. The depth of anesthesia is monitored by a bispectral index sensor (target 40–60). Bispectral Index (BIS) is a new electroencephalogram ... with an age range of 18-37 years, 20 (58.8%) samples with an age range of 38-57 years and 7 (20.6%) samples with age ... it was found that distribution of demographics data based on age group was normal with p> 0.05 with mean (mean ± SB) of 49.7 ± 1.0. The model was developed by recording and studying this type of data from more than 1,000 electroencephalograms from normal volun- Bispectral Index™ (BIS™) monitoring enhances your patient-targeted . This figure is obtained from the mathematical analysis of the electroencephalogram. Dolphin is the common name of aquatic mammals within the infraorder Cetacea.The term dolphin usually refers to the extant families Delphinidae (the oceanic dolphins), Platanistidae (the Indian river dolphins), Iniidae (the New World river dolphins), Pontoporiidae (the brackish dolphins), and the extinct Lipotidae (baiji or Chinese river dolphin). A formal conflict of interest policy was developed a priori and enforced throughout the process. tried to monitor seizures using bispectral index in [3] and Ye . The BIS monitor displays a single number that ranges from 0 (silent, flat EEG) to 100 (normal awake state). Median and IQ range of stay in ICU 15.5 and 20 days, of mechanical ventilation 9 and 14 days, of SAD 6 and 5.5 days and of paralyzing drugs (PD) 2 and 5 days, respectively. Moderate to high correlations were found between the sedation scores of these scales and either electroencephalogram (EEG) or bispectral index (BIS) values (244, 246, 258). BIS™ technology ...

Capnography and the Bispectral Index—Their Role in Pediatric Sedation: A Brief Review. It is the LMB molecule which then reduces the ferric iron of metHb to the ferrous state of normal hemoglobin. Bispectral index (BIS): This technique is mostly used to monitor depth of surgical anaesthesia in the operating theatre; it provides a quantitative value between 0 and 99. A formal conflict of interest policy was developed a priori and enforced throughout the process. The bispectral index (BIS) is a common tool to deter-mine the depth of the sedative state. We report two cases who exhibited a decrease in their bispectral index (BIS™) score, associated with syncope during venipuncture in patients with suspected needle phobia. Called the Bispectral Index (BIS), this monitor provides discrete values ranging from 100 (completely awake) to less than 60 (deep sedation), to less than 40 (coma) by incorporating several frontal electroencephalogram components.

In case 1, the reduction in BIS score occurred during the development of hypotension and bradycardia and may well have been caused by cerebral hypoperfusion. Bispectral analysis is a mathematical technique of signal processing that quantifies the degree of phase coupling between different frequency components within a signal.2 In the present commercially available system (A-1000, Aspect medical systems, Natick, MA, USA), output is in the form of a dimensionless bispectral index (BIS) that Interrelation was detected between all the SRSs, with p < 0.0001.

Summary. Objectives: A daily part of emergency medicine practice includes assessing patients with altered levels of consciousness (ALOC). methods. repre-sented an anesthesia index using bispectral analysis in [4]. There was no difference in the incidence of sleep during the experimental phases, nor in the incidence of insomnia or somnolence in the following 24 hours. HR and SpO2 remained always in a normal range. Results: For the patients with OSA, the percentages of velopharynx, oropharynx, hypopharynx, and larynx obstructions under light sedation were 77.8%, 63.3%, 30%, and 33.3%, respectively.

To optimally monitor sedation levels, Bispectral Index (BIS) monitoring has been gaining increasing interest and may be useful, given its objectivity and replicability (6-8). The bispectral index (BIS) is a complex parameter derived from a multivariate analysis of the electroencephalogram (EEG) signal. The authors hypothesized that a bispectral index monitor (BIS), a processed electroencephalographic monitor traditionally used to monitor patients under anesthesia, would represent an objective quantification of impairment of … The average BIS was 45 and only 6 patients had BIS maintained below the normal lower range of 40. Bispectral index (BIS) monitoring has been used to monitor the depth of anesthesia and might also permit improved accuracy of titration of anesthetic doses to individual patient requirement; therefore, may have relevance regarding reducing recovery time.
