Computers in anaesthesia

Abstract

The application of computers to anaesthesia has increased steadily in recent years. This trend will likely accelerate as advances in computer technology produce increasingly powerful computer systems that continue to decline in cost. The growing role of the computer makes it reasonable to expect some knowledge of its capability as part of the training of any anaesthetist.l Few professional areas can match the potential for computer applications that exist in anaesthesia and medicine generally. The need for fast, accurate information and reliable, precise electronic instruments is striking. Moreover, the relatively late development of medical applications means that much of the required technology has already been developed by faster-moving disciplines.The basic principles of computer systems, hardware, and software will be reviewed in order to facilitate a discussion of specific application areas of interest to the anaesthetist. We will identify six main areas: (a) record management, (b) departmental organization, (c) patient monitoring, (d) automation of anaesthesia, (e) computer-assisted learning, and (f) consultation systems. Other areas include many conventional functions which are not specifically aimed at anaesthetists, such as word processing, financial management, and statistics; these will not be dealt with here.

Artificial Intelligence-Supported Systems in Anesthesiology and Its Standpoint to Date—A Review

“…For example, computer AI is able to interpret X-ray investigations and generate a report or another example is a computer large language model (LLM), such as ChatGPT is able to read, think, understand and answer questions [18]- [23]. Forty years ago, applications of computer technology in anesthesiology were reviewed in the literature [24]. Twenty-five years later, automatic intravenous anesthesiology was discussed [25].…”

Computer in der Anästhesie - Wo stehen wir heute?

“…Die vorliegende Ubersicht von Petersen u.Mitarb. (6) verdeutlicht jedoch, daß selbst im Bereich von Expertensystemen der Computer ärztliches und pflegerisches Personal lediglich beraten, Entscheidungen absichern (10) und möglicherweise auch komplexere Venvaltungsaufgaben erleichtern kann. Dieses sollte dazu beitragen, die Qualität der medizinischen Versorgung zu verbessern und die Informations-und Entscheidungsdichte für das Personal zu erhöhen.…”
