“…9,10 There is no information in the current literature concerning the influences of multiple ECTs on BIS measurements. 11 This is the first study to examine the effect of ECT course on preanesthesia BIS values. Our findings suggest that the standard interpretation of BIS values may not hold good for patients going through a course of ECT.…”

Bispectral index values of awake individuals in resting state drop significantly through a course of bitemporal brief-pulse ECT. Anesthesiologists should be aware that a considerable proportion of patients who have received a course of ECT may have BIS values in the sedated/anesthetized range even when they are awake. The BIS may not provide accurate estimation of the depth of anesthesia during ECT after the initial ECT sessions.

Background. Endovascular techniques for treatment of intracranial aneurysms are increasingly commonly applied. In general, the procedures are short, require general anaesthesia and complete immobilisation of patients. The aim of the present study was to assess the usefulness of general anaesthesia with propofol and laryngeal mask airway for endovascular management of intracranial aneurysms based on analysis of haemodynamic stability. Methods. The study encompassed 26 patients undergoing endovascular treatment of intracranial aneurysms. The mean arterial pressure (MAP), heart rate (HR), bispectral index (BIS), end-tidal CO 2 (E T CO 2 ) and haemoglobin saturation with oxygen (SpO 2 ) were determined at eight measurement points: T 1 -before anaesthesia induction, T 2 -after induction, T 3 -after LMA insertion, T 4 -during arteriography, T 5 -during "coiling" , T 6 -at completion of propofol infusion, T 7 -before LMA removal, T 8 -after LMA removal. Results. MAP and HR were found significantly reduced between T 2 and T 1 . To maintain BIS within the range of 40-60, the following propofol infusion rates (in mg kg b.w. -1 h -1 ) were required: T 2 -4.5 ± 0.3; T 3 -4.6 ± 0.7; T 4 -4.5 ± 0.8 and T 5 -4.4 ± 0.6. E T CO 2 and SpO 2 were not demonstrated to be changed. The mean duration of anaesthesia and of recovery was 64.3 ± 21.8 and 8.9 ± 4.8 min, respectively. Conclusions. General anaesthesia with propofol and LMA ensures suitable conditions for endovascular treatment of intracranial aneurysms.

“…A sensitive balance is required between providing optimal seizure duration and achieving a sufficient depth of anesthesia (1). Whereas high-dose anesthetic agents might reduce the effectiveness of ECT, low-dose agents may not provide an adequate depth of anesthesia and may also negatively affect the progress of the psychiatric disease (7,8). Direct measurement of the individual hypnosis level is reported to help in determining the anesthetic dosage and ECT application time, as well as reducing awareness (9,10).…”

Bispectral index-controlled anaesthesia for electroconvulsive therapy*

Abstract: Methohexital for ECT showed a great variability, exceeding as well as undershooting the dosage recommendations widely. BIS monitoring may be useful to secure adequate hypnosis during muscle relaxation and treatment and may optimize ECT efficacy.
