[An attempt to determine optimum dosage of fentanyl in neurolept analgesia (author's transl)].

In a retrospective study a comparison was made of the doses of Fentanyl used by anaesthetists to induce and maintain neurolept analgesia for a variety of surgical operations (158 cases). Dosages differed widely both for different surgical procedures and for different anaesthetists. A method, based on pharmacokinetic considerations, was developed for calculating Fentanyl requirements during any stage of anaesthesia. The dose/time relation, as represented by y = At + B (1--e-kt) makes it possible to calculate the required doses of Fentanyl; this enables the anaesthetist to maintain a stable level of anaesthesia and makes antagonization of Fentanyl unnecessary. Methods for determining the coefficients of the dose-time equation are described. Simulation by an analogue computer showed that by using the suggested procedure substantial variations of Fentanyl concentration in the brain and other body compartments can be avoided.

First experiences with a documentation system via display terminals.

A documentation and monitoring system has been developed by members of the Department of Anesthesiology and the Department of Medical Data Processing of the Rheinisch-Westfälische Technische Hochschule Aachen. It is conceived in such a way that it should cover all the needs of the department, which is to say that every anesthesia done by a staff member should be documented, supervised and assisted by the computer service. The anesthesiological staff works only with 16 color visual display units, which are installed in the different operation theatres and in the intensive care unit of the department. These devices are used as an inquiry-response system for the dialogue between medical operator and computer. They display both alphanumerics and graphics in four different colors and modes. Information is entered in the system via so-called masks, which contain a larger section of information, and by on-line data recording.
