Popis: The circulatory effects of enflurane were studied in ten unmedicated normocarbic volunteers during anaesthesia over a period of 90 minutes or more. Cardiac output did not change significantly during anaesthesia at a mean alveolar anaesthetic concentration of 2.3 volumes per cent and ranging from 1.8 to 3.2. Systolic, diastolic and mean arterial pressures decreased significantly, as did total peripheral resistance. The heart rate increased in all cases. Cardiac output was maintained primarily by an increased heart rate, which compensated for the decreased total peripheral resistance. At recovery, all haemodynamic parameters except heart rate returned to control levels. Minimal change in cardiac output during enflurane anaesthesia in man may be related to the combination of decreased mean arterial pressure and increased heart rate.
