Correlation and agreement between bispectral index and state entropy of the electroencephalogram during propofol anaesthesia.
BACKGROUND Bispectral index (BIS) and state entropy (SE) monitor hypnosis. We evaluated the correlation and the agreement between those parameters during propofol anaesthesia and laryngoscopy with and without muscle relaxation. METHODS A total of 25 patients were anaesthetized with propofol. At steady state (SS: BIS 40-50), they randomly received rocuronium (R) or saline (S); 3 min thereafter...
متن کاملDUPLICATE PUBLICATION: Comparison of entropy and bispectral index values during propofol induction.
OBJECTIVE To identify the entropy levels that would correspond to bispectral index (BIS) levels in general anesthesia (GA) induction in patients who will undergo elective lumbar disc surgery (LDS). METHODS Thirty cases who underwent LDS under GA were included in our study after obtaining patient consent and approval of the Ethics Committee of Afyon Kocatepe University Medical School, Afyonkar...
متن کاملEffect of landiolol on bispectral index and spectral entropy responses to tracheal intubation during propofol anaesthesia.
BACKGROUND beta1-Adrenoceptor antagonists suppress the haemodynamic and arousal responses to tracheal intubation. The Entropy Module shows two spectral entropy-based indices, response entropy (RE) and state entropy (SE). The difference between RE and SE (RE-SE) may reflect nociception during general anaesthesia. In the present study, we investigated the effect of landiolol on entropy indices in...
متن کاملSignal Persistence of Bispectral Index and State Entropy during Surgical Procedure under Sedation
INTRODUCTION Bispectral index (BIS) and state entropy (SE) are prone to artifacts, especially due to electrocautery (EC). We compared the incidence of artifacts in BIS and SE during surgery under local anesthesia and sedation. METHODS 28 females undergoing breast surgery under local anesthesia and sedation were studied. Simultaneous BIS and SE measurements were recorded every 10 seconds. Arti...
متن کاملSpectral entropy measurement of patient responsiveness during propofol and remifentanil. A comparison with the bispectral index.
BACKGROUND We compared two spectral entropies, state entropy (SE) and response entropy (RE), based on the irregularity of the EEG, to measure loss of response to verbal command (LOR(verbal)) and noxious stimulus (LOR(noxious)) with the bispectral index (BIS) during propofol infusion with and without remifentanil. METHODS Three groups of 20 patients received an effect-site controlled propofol ...
