[Changes in vital functions in endoscopic interventions by various anesthesia and ventilation conditions].
Three different mixed anaesthesias were compared and monitored as for the behaviour of vital functions (heart frequency, RR, ECG, respiration, pO2tc, blood gases) during endoscopy of the air passages in 3 patient groups (n = 36), using one complex measuring set-up. Hypertonic blood pressure rises and increase in the heart frequency were regularly demonstrated in all methods of anaesthesia. Initial cardiac depression with a drop of frequency and blood pressure was observed for the first time within the first minute after the injection of Hexobarbital or Radenarcon in 70 per cent of the cases. The Radenarcon-succicuran-O2 combination showed the highest rate of arrhythmia. Significantly high pO2 levels (400 torr) were attained only under pure oxygen respiration and in no case with nitrous oxide or room-air oxygen mixtures (injector respiration). The time of apnoea could be extended maximally without danger signals, provided the supply of oxygen was accordingly high.
