[Effect of ethrane on the circulatory parameters of geriatric patients (author's transl)]

The cardiovascular effects of enflurane in geriatric patients have been compared with the effects of this anaesthetic agent in a group of young patients. The degree of cardiovascular depression in geriatric patients was much greater than in the young patients despite the smaller inspired concentration of enflurane necessary to produce a similar depth of anaesthesia. In comparison with halothane and neuroleptanaesthesia, enflurane produced the greatest decrease in cardiac output. The mean arterial pressure, however, was quite well maintained due to a simultaneous increase in total peripheral resistance.
