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 کاملEffect of sugammadex or neostigmine neuromuscular block reversal on bispectral index monitoring of propofol/remifentanil anaesthesia.
BACKGROUND Sugammadex is a modified γ-cyclodextrin with a novel mechanism of action for reversing the steroidal neuromuscular blocking agent rocuronium. Bispectral index (BIS) is an EEG-derived measure which can be sensitive to frontal electromyographic (EMG) artifacts. We compared BIS values before and after sugammadex or neostigmine neuromuscular block (NMB) reversal in patients with or witho...
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 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 کاملEffects of fentanyl, alfentanil, remifentanil and sufentanil on loss of consciousness and bispectral index during propofol induction of anaesthesia.
The bispectral index (BIS) and a sedation score were used to determine and compare the effect of propofol in the presence of fentanyl, alfentanil, remifentanil and sufentanil. Seventy-five non-premedicated patients were assigned randomly into five groups (15 in each) to receive fentanyl, alfentanil, remifentanil, sufentanil or placebo. Opioids were administered using a target-con-trolled infusi...
