Effect of remifentanil on plasma propofol concentration and bispectral index during propofol anaesthesia.
BACKGROUND Propofol and remifentanil are commonly administered together in clinical anaesthesia, but the effect of remifentanil on the plasma concentration of propofol has yet to be established. The aim of the present study was to investigate the effect of remifentanil on plasma propofol concentrations (Cp) in the absence of surgical stimulation. METHODS Thirty-eight patients undergoing elect...
متن کاملBispectral index monitoring during electroconvulsive therapy under propofol anaesthesia.
BACKGROUND The accuracy of the bispectral index (BIS) as a monitor of consciousness has not been well studied in patients who have abnormal electroencephalograms (EEG). METHODS We studied the changes in BIS, its subparameters, and spectral entropy of the EEG during 18 electroconvulsive treatments under propofol and succinylcholine anaesthesia. A single bifrontal EEG, and second subocular chan...
متن کاملClonidine premedication decreases propofol consumption during bispectral index (BIS) monitored propofol-ketamine technique for office-based surgery.
BACKGROUND Propofol-ketamine anesthesia is a room air, spontaneous ventilation (RASV), dissociative intravenous (IV) sedation technique reported to have a near-zero postoperative nausea and vomiting (PONV) rate. Clonidine premedication has been reported to control blood pressure intra- and postoperatively, as well as to reduce the requirements for hypnotic agents. The bispectral index (BIS) mon...
متن کاملEvaluation of the effect of intravenous lidocaine on propofol requirements during total intravenous anaesthesia as measured by bispectral index.
BACKGROUND I.V. lidocaine is increasingly used as an adjuvant during general anaesthesia. The aim of this study was to evaluate the effect of i.v. lidocaine in reducing propofol anaesthetic requirements during total i.v. anaesthesia (TIVA) maintenance and to evaluate its effect on early recovery from anaesthesia. METHODS Forty adult patients undergoing elective laparoscopic cholecystectomy un...
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...
