Zusammenfassung

Anwendung eines Anti-Gravitationsanzuges bei neurochirurgischen Patienten mit lagerungsbedingter Hypotonie. Akuter Blutdruckabfall bei Operationen in sitzender Lagerung kann mit Hilfe eines Luftdruckanzuges, der von den Sprunggelenken bis zum Xiphoid reicht, erfolgreich und rasch behoben werden. Der durchschnittlich gemessene Anstieg des systolischen Blutdrucks über den Ausgangswert betrug 60%, wobei ein reziprokes Verhältnis zwischen Ausgangswert und Blutdruckanstieg auffiel. Somit können im Gegensatz zu früher alle drucklabilen Patienten in schlechtem Allgemeinzustand dem indizierten Eingriff unterzogen werden. Die Wirkung äußerlichen Drucks auf die untere Körperhälfte wird mit Erhöhung des peripheren Widerstands und Abnahme der Durchströmung erklärt, aus denen Verbesserung des venösen Rückstromes, Verlagerung des zirkulierenden Volumens über das Diaphragma und Anstieg des systolischen Drucks resultieren.

Summary

The use of the “Anti-G-Suit” in patients with postural hypotension is described. Acute falls in the blood pressure during operations in the sitting position can be successfully treated with the aid of an external counter-pressure garment reaching from ankles to xiphoid process. The mean increase in systolic blood pressure was about 60% in hypotensive and 17% in normotensive control patients. A reciprocal relation between pre-treatment blood pressure and its increase after use of the “G-Suit” was noticed. In contrast to previous practice, we were able to operate on all hypotensive patients in poor condition. The effect of external counterpressure on the lower part of the body can be explained by increase of peripheral resistance and decrease of vascular flow, resulting in better venous return, displacement of the circulating blood above the diaphragm and augmentation of systolic blood pressure.
