[Inhalation anesthesia and intravenous anesthesia from the medical and economic viewpoint]

The unique pharmacokinetic properties of propofol gave rise to a widespread use of the technique of total intravenous anaesthesia. These properties of propofol are reviewed and compared to those of barbiturates and benzodiazepines. Based on this comparison and with respect to their respective intra- and postoperative effects, a cost-benefit analysis of both inhalational- and intravenous anaesthesia is presented. The choice of an anaesthetic technique must not only be made with regard to medical implications; economical aspects have also to be taken into account without challenge to the quality of care. A consequent use of low-flow techniques and a market oriented purchase of drugs and disposables may allow cost savings in anesthesia.
