Zusammenfassung
Hintergrund
Die regionale Zitratantikoagulation (RCA) ermöglicht eine effektive Antikoagulation des Dialysekreislaufs, ohne die systemischen Nebenwirkungen einer Heparinisierung zu haben. Insbesondere ist sie bei den kontinuierlichen Verfahren gut etabliert und stellt ein sicheres Verfahren dar, das zu längeren Filterlaufzeiten und weniger Blutungskomplikationen führt.
Ziel der Arbeit
Um Indikation, Vor- und Nachteile sowie die Anwendung der RCA aufzuzeigen, werden aktuelle Empfehlungen der Sektionen Niere der Deutschen Gesellschaft für Internistische Intensivmedizin und Notfallmedizin (DGIIN), der Österreichischen Gesellschaft für Internistische und Allgemeine Intensivmedizin und Notfallmedizin (ÖGIAIN) und der Deutschen Interdisziplinären Vereinigung für Intensiv- und Notfallmedizin (DIVI) dargestellt.
Material und Methoden
Die Empfehlungen dieser Arbeit basieren auf den aktuellen KDIGO-Leitlinien (Kidney Disease: Improving Global Outcomes), diversen sonstigen publizierten Leitlinien und Protokollen sowie der Expertenmeinung und klinischen Erfahrung der Autoren.
Ergebnisse
Maßgeblich für die Sicherheit der RCA bei Nierenersatzverfahren ist eine hinreichende Schulung, die Verwendung konfektionierter Systeme mit gekoppelten Pumpensystemen und die feste regionale Etablierung des Verfahrens optimaler Weise mit Standardarbeitsanweisungen (SOP). Auch bei Patienten mit Leberversagen oder Kreislaufschock mit Laktatacidose besteht entgegen früherer Empfehlungen keine absolute Kontraindikation zur RCA mehr, jedoch sollte insbesondere hier auf die Zeichen einer möglichen Zitratakkumulation geachtet werden
Abstract
Background
Regional citrate anticoagulation (RCA) in continuous renal replacement therapy can effectively anticoagulate dialysis circuits without having adverse effects on systemic heparin application. In particular, in continuous renal replacement therapy RCA is well established and represents a safe procedure with longer filter lifetimes and fewer bleeding complications.
Objectives
To provide guidance on the indications, advantages and disadvantages, and use of RCA, current recommendations from the renal section of the DGIIN (Deutschen Gesellschaft für Internistische Intensivmedizin und Notfallmedizin), ÖGIAIN (Österreichischen Gesellschaft für Internistische und Allgemeine Intensivmedizin und Notfallmedizin) and DIVI (Deutschen Interdisziplinären Vereinigung für Intensiv- und Notfallmedizin) are stated.
Materials and methods
The recommendations in this paper are based on the current KDIGO (Kidney Disease: Improving Global Outcomes) guidelines, other published guidelines and protocols as well as the expert knowledge and clinical experience of the authors.
Results
The use of commercially available machines with coupled pumps and integrated safety features, effective personal training and standardized protocols for clinical usage (SOP) is particularly important for the safe clinical use of RCA in renal replacement therapy. Contrary to previous recommendations, even liver failure or shock with lactic acidosis may no longer be an absolute contra-indication for RCA. However, these particular patients have to be carefully monitored for signs of citrate accumulation.
