“…The wide diversity in indices seen in the present study was also seen by Recart et al [16], who compared BIS and auditory evoked potential during general surgery, and was also similar to the results of Schneider et al [10]. The latter compared BIS and patient state index in patients undergoing heart surgery [10].…”

“…Whether the use of anaesthetic depthmonitors would affect the outcome was not studied. Our study design is purely explorative and identical to the design that Schneider et al [10] used to compare the BIS and patient state index.…”

Clinical comparison of three different anaesthetic depth monitors during cardiopulmonary bypass

SummaryThe lack of a gold standard complicates the evaluation and comparison of anaesthetic depth monitors. This randomised study compares three different depth-of-anaesthesia monitors during cardiopulmonary bypass (CPB) at 34°C with fentanyl ⁄ propofol anaesthesia adjusted clinically and blinded to the monitors. Coronary artery bypass grafting patients (n = 21) were randomly assigned to all three possible paired combinations of three monitors: Bispectral Index (Aspect Medical), AAI TM auditory evoked potential (Danmeter), Entropy TM (Datex-Ohmeda). Indices were manually recorded every 5 min during CPB. Agreement between paired indices was classified as good, non-, or disagreement. Anaesthesia was classed as adequate, inadequate, or excessive according to recommended index values. Of the 255 paired indices recorded, 62% showed good agreement, 33% showed non-agreement, and 5% showed disagreement. Using good agreement between two monitors as a gold standard, a quarter of the measurements indicate inappropriate anaesthetic depth monitoring during CPB with clinically titrated anaesthetic depth.

“…The Pk concept can also be used for measuring whether changes in a drug concentration during ongoing surgery is reflected more monotonously by one monitor or the other (12). Further on, comparisons in the form of simple correlations between two indexes have also been published (13).…”

Can the Cerebral State Monitor replace the Bispectral Index in monitoring hypnotic effect during propofol/remifentanil anaesthesia?

“…When the hypnotic effects of single anesthetic agents (volatile or intravenous) are assessed with BIS technology, a surgical level of anesthesia is usually encountered between a BIS of 40 and 60. There is some controversy about the clinical usefulness of measuring anesthetic depth with processed EEGs (441,450,451,550,614), but in the absence of surgical stimulation and during the use of a single agent there is a good inverse linear relationship between the numerical BIS value and increasing anesthetic plasma concentrations. Hoshino et al (279) assessed respiratory timing and upper airway responses to decreases in nasal pressure in nine propofolanesthetized healthy subjects.…”

This article provides a comprehensive, up to date summary of the effects of volatile, gaseous, and intravenous anesthetics and opioid agonists on ventilatory control. Emphasis is placed on data from human studies. Further mechanistic insights are provided by in vivo and in vitro data from other mammalian species. The focus is on the effects of clinically relevant agonist concentrations and studies using pharmacological, that is, supraclinical agonist concentrations are de-emphasized or excluded.
