Eeg Atlas For Anesthesiologists

This atlas offers a collection of EEG spectral analyses and their corresponding conventional recordings under anes thesio10gical procedures. The EEGs presented here were re corded on general surgical and gynecological patients during the last few years. Premedication, induction and maintenance of anesthesia, recovery the immediate postoperative period, and intensive care are covered. Techniques for operating the necessary equipment and artefacts relevant to the routine clinical use of EEG are briefly outlined. Typical examples of characteristic EEGs are presented at the beginning of each chapter, followed by illustrations of deviations from the norm showing the great variety of anesthesiologically induced changes of cerebral function. The description of each EEG course is assessed in relation to clinical parameters. Sometimes no satisfactory interpreta tion can be made, because many physiological and patho physiological causes of alterations in cerebral function are unknown. Time and again it proves impossible to estimate wether deviations from the norm have their origin in cerebral changes or are secondary to extracerebra1 disturbances. The atlas comprises a complete survey in itself, but it can also be seen as a supplement to the book The Electroenceph alogram in Anesthesia by I. Pich1mayr, U. Lips, and H. Kunkel (Springer, 1983), in which detailed lists of references are quoted that are omitted here.

Neurological, neurovegetative, and psychic changes following surgery or in tensive care indicate alterations in cerebral function. When these changes are analyzed exactly, they are found to be by no means rare; at the same time, they present a wide spectrum of clinical manifestations. While optimal circulatory monitoring - including continuous EEG recording during anes thesia or intensive care - is today regarded as routine, the problem of objec tive and continuous monitoring of cerebral function under various forms of anesthesia, surgery, and intensive care has not been solved. Considerable improvements in clinical neurophysiology, mainly through visual and spectral analytic evaluations of the EEG, show func tional neurophysiological changes to be equivalent to, or the cause of, clinical, neurological, and psychic changes. The question of current interest, therefore, is whether anesthesiological EEG monitoring is able, both theo retically and practically, to detect and adequately interpret cerebral altera tions following perioperative measures such that these alterations can be treated or avoided accordingly. In the long run, the basic questions are to what extent can anesthesiological measures be guided by the EEG pattern and managed effectively, and can EEG analysis be significant both for the individual patient and in the general interpretation of the effect of anes thesiological procedures? Questions of the relevance and practicability of anesthesiological EEG monitoring are dealt with in this book. This study is based on an analysis of more than 1500 EEGs of patients who underwent anesthesia during surgery.

Organized by wave features rather than pattern names, this atlas helps guide the reader to an EEG interpretation even when the waveform is unfamiliar. The first section takes the reader through the process of characterizing EEG waves by their features. The second section organizes EEG patterns by their features, so provides EEG waveform differential diagnoses. The third section is organized alphabetically by pattern name with each pattern described in a way that allows the reader to distinguish it from similarly appearing patterns. Examples of the patterns also are provided.

First multi-year cumulation covers six years: 1965-70.
