A useful application of BIS in ICU is monitoring for seizures that might be subclinical or unrecognised in patients receiving NMB 68. The BIS device consists of a transducer that's connected to a monitor on one end and the patient's forehead via an adhesive electrode sensor strip on the other. All patients that are receiving neuromuscular blockade.

Hello. Nineteen studies comparing the BIS with sedation scales were evaluated, revealing that the BIS trends lower with increasing sedation. Neurophysiological assessment of brain dysfunction in critically ill patients: an update. BIS index is a practical processed EEG parameter that measures the direct effects of sedatives on brain. M8002A BIS interface # J16 board for MP30 In the ICU, BIS monitoring has been shown to reduce recall of unpleasant experiences and provide objective sedation assessment during: • Mechanical ventilation • Neuromuscular blockade • Barbiturate coma • Bedside procedures Well managed sedation levels in the ICU can also aid in ventilator weaning. doi: 10.1002/14651858.CD011240.pub2.  |  Most studies were done on consecutive ICU admissions. Bispectral Index (BIS) has been used to measure the level of sedation in critically ill patients [].The biggest problems were the artefacts raising from facial muscle or eye movements, and the wide variability of analysed clinical conditions [].BIS-XP is a new available device (Aspect, USA), with one more frontal electrode, that should minimise the movement related artefacts. IEEE Trans Biomed Eng. The BIS appeared to correlate better when sedation scores were grouped rather than individual values. Data sources: The bispectral index is a statistically based, empirically derived complex parameter.

The 2002 Society of Critical Care Medicine Sedation Guidelines recommendation that more data are needed before the BIS should be used routinely in the ICU remains unchanged. REFERENCES Indications for Use: 1. Overall, BIS monitoring is an easy-to-use adjunct to monitoring sedation in the critically ill patient that may reduce costs, morbidity, and mortality related to seda-tion in the ICU. Continuing Education Disclosure Statement What is BIS monitoring in ICU? 2000;4(suppl 1):S110. The BIS represents a method of monitoring that can be an important adjunct to clinical assessment and other monitoring modalities used in the ICU setting. St. Joseph Regional Medical Center, Mishawaka, IN, No Product/Research Disclosure Information. Nevertheless, one of the potential uses of BIS monitoring in the ICU should be to detect oversedation. Crit Care. The aim of this study was to clarify whether or not therapeutic drug monitoring is useful to assess the sedation depth in intensive care patients. Epub 2019 Sep 23. Nurses Nursing. Shetty RM, Bellini A, Wijayatilake DS, Hamilton MA, Jain R, Karanth S, Namachivayam A. Cochrane Database Syst Rev. Outcomes data are lacking. Article BIS monitoring versus clinical assessment for sedation in … BIS monitoring, however, has been shown to be less reliable in anesthetics involving higher-dose opioids and is insensitive to several commonly used anesthetic agents such as ketamine and nitrous oxide. Cite. • REFERENCES 1. To assess the effects of BIS monitoring compared with clinical sedation assessment on ICU length of stay (LOS), duration of mechanical ventilation, any cause mortality, risk of ventilator-associated pneumonia (VAP), risk of adverse events (e.g.  |  BIS Monitoring in ICU. ICU: minimize over/undersedation, potentially lowering costs Kaplan L ,Bailey H. Bispectral Index (BIS) monitoring of ICU patients on continuous infusions of sedatives and paralytics reduces sedative drug utilization.

RESULTS: Average number of patients evaluated was 27. Published by Elsevier Inc. All rights reserved. Implementation of BIS™ technology is often associated with OR clinicians monitoring brain function during sedation. To monitor a patient, you will need a monitor or a module and a sensor. This technology is finding its way into the ICU to provide a means of assessing the adequacy of sedation and preventing oversedation of critically ill patients. 20th Sep, 2019. Thank you all so much. ECMO. The study aimed to investigate the correlation between the BIS index and the prognosis of patients with coma in the ICU. 2018 Sep 14;6:62. doi: 10.1186/s40560-018-0331-7. The bispectral (BIS) index is a processed electroencephalogram (EEG) parameter with extensive validation and demonstrated clinical utility. Purpose: Appropriate treatment of generalized convulsive refractory status epilepticus (RSE) requires general anesthesia in the intensive care unit (ICU) with continuous electroencephalography (cEEG) monitoring. For those working in Intensive Care Do you ever use BIS Monitoring when you have sedated and ventilated patients, and if so, I would like to know what you think from your experience both with and without Neuromuscular Blocking Agents. NLM Some controlled studies have found that using the BIS reduced the incidence of memory but this was not confirmed in several very large multicenter studies on awareness. Please enter a term before submitting your search. Interpreting literature on the usefulness of the BIS in the ICU is difficult for reasons that include heterogeneous populations, different methods of collecting BIS data, and use of different versions of BIS software and hardware. COVID-19 is an emerging, rapidly evolving situation. 27. Data synthesis: Nineteen studies comparing the BIS with sedation scales were evaluated, revealing that the BIS trends lower with increasing sedation. HHS Earlier emergence with desflurane, compared with sevoflurane and propofol, was also reported when bispectral index (BIS) monitoring was used to titrate the hypnotic agents. This site needs JavaScript to work properly. It is a weighted sum of electroencephalographic subparameters, including a time domain, frequency domain, and high order spectral subparameters. A manual search of abstracts was also performed using the key search terms BIS, sedation, and critical care. The sensor on forehead sends raw EEG information to the BIS engine. BIS values increased, indicating that his sedation could be increased without oversedating him. Both loss of consciousness and awakening from anesthesia are correlated with this scale. 2015 Nov 12;13:Doc19. The BIS is an electroencephalogram-derived multivariant scale that, when a drug such a propofol is used, correlates with the metabolic rate of glucose. The experts suggest closely monitoring the signs of secondary infection, especially in critically ill patients with COVID-19 who have been admitted to ICU > 48 h (expert opinion). 2018 Feb 21;2(2):CD011240. The correlations between serum concentrations and subjective monitoring procedures (RASS and Ramsay Scores) as well as objective monitoring procedures (BIS-monitoring) were investigated in this study. NIH Randomized, controlled trials demonstrating improved outcomes with BIS monitoring have not been reported. To review and critique evidence for the use of the bispectral index (BIS) in intensive care unit (ICU) patients. This system al-lowed for easier, more prompt extubation and a de-creased stay in the ICU. , those who were exposed to a risk of oversedation much more than others.

BIS™ Monitoring Technology Increases Sedation Assessment Capabilities in the ICU. The BIS monitor provides a single dimensionless number, which ranges from 0 (equivalent to EEG silence)to 100 (equivalent to fully awake and alert). Posted Jun 20, 2015. Bispectral index (BIS) monitoring, an objective measure of the patient's response to sedation, has been used in anesthesia for over a decade. The two to four sensors on the strip each have numbers that indicate where on the forehead they should be placed for optimal EEG signal analysis. The Bispectral Index (BIS) monitor can be used to assess the hypnotic component of general anesthesia. BIS monitoring has been used for monitoring anesthesia effects in the operating room for a number of years.
