| Summary: | 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
