Summary
Complete cerebral ischemia of 30 and 60 min was produced in normothermic cats by arterial clamping and lowering of the blood pressure. The functional impact was monitored by electrophysiological methods. In animals without functional recovery blood flow was not fully restored after ischemia. In the animals in which signs of neuronal function returned, ischemia was followed by a transient phase of hyperemia, the termination of which coincided with the return of spontaneous EEG activity. At this time cerebrovascular autoregulation was present, but CO2 responsiveness was still completely abolished, and vasoactive drugs (papaverine, aminophylline, alpha adrenergic blocking agents, hydergine) failed to increase cerebral blood flow.
Zusammenfassung
An normothermen Katzen wurde die Durchblutung des Gehirns für eine Dauer von 30 und 60 min durch Abklemmen der Aa. innominata und subclavia sinistra bei gleichzeitiger Blutdrucksenkung vollständig unterbrochen. Die Auswirkung der Ischämie auf das Hirn wurde elektrophysiologisch verfolgt. Bei Tieren ohne funktionelle Erholung war die Blutrezirkulation im Anschluß an die Ischämie erheblich vermindert. Traten jedoch Zeichen funktioneller Erholung auf, so war die Durchblutung nach der Ischämie erhöht und normalisierte sich erst, wenn die ersten spontanen EEG-Wellen zurückkehrten. Zu diesem Zeitpunkt hatte sich die Autoregulation, nicht aber die CO2-Reaktivität der Hirngefäße normalisiert. In der postischämischen Phase konnte eine Steigerung der Hirndurchblutung durch vasoaktive Substanzen (Papaverin, Aminophyllin, Alpha-Receptoren-blokkierende Substanzen, Hydergin) nicht erzielt werden.
