Evoked potentials during isoflurane anaesthesia.
Somatosensory, visual and brainstem auditory evoked potentials were recorded in 10 unpremedicated patients anaesthetized with isoflurane in oxygen. Recordings were made at 0.5%, 1.1% and 1.65% (six patients) end-tidal isoflurane concentration. There were statistically significant increases in the latencies of the somatosensory (N20), visual and brainstem auditory potentials (waves III and V) wi...
متن کاملUptake of isoflurane during prolonged clinical anaesthesia.
Recent evidence has suggested that the rate of uptake of inhalational anaesthetic is constant during maintenance of anaesthesia, contrary to the predictions of multi-compartment uptake models. We measured isoflurane uptake using a totally closed anaesthetic system during up to 10 h of stable anaesthesia for maxillo-facial surgery on 12 adult patients. Liquid isoflurane was injected into the sys...
متن کاملHaemodynamic effects of isoflurane during propofol anaesthesia.
We have studied haemodynamic responses to 0, 0.25, 0.5, 0.75 and 1 MAC isoflurane administration in 10 patients during a zero-order propofol infusion and normocapnia. Isoflurane reduced mean arterial pressure (MAP), systemic vascular resistance and left ventricular stroke work in a dose-dependent manner (29%, 38% and 33%, respectively, at 1 MAC), while cardiac output (CO), stroke volume (SV) an...
متن کاملProcessed electroencephalogram during combined extradural and general anaesthesia.
The processed electroencephalogram (pEEG) was monitored in eight patients undergoing gynaecological laparotomy under combined extradural and nitrous oxide-isoflurane anaesthesia. Pre-incisional mean spectral edge frequency 95 percentile (SEF95) and median frequency (MF) were 11.67 (SD 1.63) Hz and 3.74 (0.24) Hz, respectively. After skin incision, both SEF95 and MF decreased to 6.61 (2.04) Hz a...
متن کاملThe practical value of the electroencephalogram during anaesthesia.
THE INTRODUCTION Of a wide variety of anaesthetac agent,;, the develo'gmcnt of many new and complex tectmlques, and the ever increasing magmtude o_" surgical procedure have so altered the practice of c~inlcal anaesthesia that the tradilaonal concepts of the signs of anaesthette depth are no longer adequate or accurate. The scheme for the clinxcal signs of anaesthesia elaborated by Guedel (1) ba...
