AbstractThe technique of target controlled infusion (TCI) has influenced the development of intravenous anaesthesia substantially and opens the possibility of many new and exciting applications in peri-operative anaesthetic care. The launch of "Diprifusor" as the first commercially available TCI system for propofol was the cornerstone of a successful research period within the last decade, which evaluated the pharmacokinetic foundations of computer assisted intravenous drug delivery. We are now in a period where TCI technology is becoming a part of routine anaesthesia technique for the practitioner rather than a research tool for specialists and enthusiasts. This review gives an update on the rational pharmacokinetic basis of TCI development, the preliminary clinical experience with the new technique, the performance and accuracy of TCI devices and potential technical pitfalls in clinical routine. Besides clinical application in anaesthesia with "Diprifusor" TCI, target controlled systems are expected to play a significant role as research tools in the evaluation of drug interactions in anaesthesia and in the development of novel control techniques for the administration of sedative and analgesic drugs in the peri-operative period.
