    Wenn die Niere im OP versagt, wird es kritisch. Erfahre, wie du durch präzise Hämodynamik und Diagnose renale Schäden frühzeitig verhinderst.

    Akutes Nierenversagen in der Anästhesie vermeiden

    Akutes Nierenversagen in der Anästhesie vermeiden最佳语录

    “

    Die Niere ist das chemische Gewissen des Körpers und oft der erste Seismograph, der ausschlägt, wenn im Organismus etwas grundlegend schiefläuft. Ein vorausschauendes Management, das über das bloße Starren auf Laborwerte hinausgeht, ist daher die beste Präventivmedizin im OP.

    Das Serum-Kreatinin gilt als Spätindikator, da es erst signifikant ansteigt, wenn die Niere bereits etwa 50 Prozent ihrer Funktion eingebüßt hat. Im klinischen Alltag wird dieser Wert oft mit einem Feuerwehrauto verglichen, das erst gerufen wird, wenn das halbe Haus bereits brennt. Daher sollte man sich eher auf die Urinausscheidung konzentrieren, wobei ein Abfall unter 0,5 ml pro Kilogramm Körpergewicht pro Stunde über einen Zeitraum von sechs Stunden als kritisches Warnsignal gewertet wird.

    Die Niere ist von einer straffen, nicht dehnbaren Kapsel umgeben. Bei einer Hypervolämie schwillt das Nierengewebe an, kann sich aber aufgrund der Kapsel nicht ausdehnen, wodurch der Druck im Inneren des Organs steigt. Dieses sogenannte Kapselödem drückt die kleinen Blutgefäße von außen zusammen und verschlechtert die Durchblutung massiv, selbst wenn der systemische Blutdruck am Monitor stabil erscheint.

    Der "Triple Whammy" beschreibt die gefährliche Kombination aus drei Medikamentengruppen: NSAR (wie Ibuprofen), ACE-Hemmer (oder Sartane) und Diuretika. Während NSAR das zuführende Gefäß der Niere verengen, stellen ACE-Hemmer das abführende Gefäß weit, was den Filtrationsdruck im Glomerulus zusammenbrechen lässt. Zusammen mit der volumenentziehenden Wirkung von Diuretika kann dies in Stresssituationen wie einer Operation zum sofortigen Nierenversagen führen.

    Bei einer Sepsis ist die Niere nicht nur durch einen niedrigen Blutdruck (Ischämie) gefährdet, sondern erleidet einen immunologisch vermittelten Kollateralschaden. Entzündungsmediatoren wie Zytokine führen zu einem "Capillary Leak" und Mikrogerinnseln in den Kapillaren. Zudem schalten die Tubuluszellen in einen energetischen "Winterschlaf", um zu überleben, wodurch sie die Urinproduktion einstellen, obwohl das Gewebe technisch gesehen noch lebt.

    Bei der regionalen Zitrat-Antikoagulation wird das Blut nur innerhalb der Dialysemaschine ungerinnbar gemacht, indem Zitrat das für die Gerinnung notwendige Kalzium bindet. Bevor das Blut in den Patienten zurückfließt, wird wieder Kalzium zugeführt. Dies verhindert das Verstopfen der Filter, ohne das systemische Blutungsrisiko für den Patienten zu erhöhen, was besonders bei frisch operierten Patienten ein entscheidender Sicherheitsvorteil gegenüber einer Heparin-Therapie ist.
