Zusammenfassung
Die Herz-Lungen-Maschine (HLM) wurde seit ihrer Einführung stetig weiterentwickelt und modifiziert. Trotz aller technischen Neuerungen und Sicherungseinrichtungen an einer modernen HLM treten während der Perfusion Probleme auf, die ein sofortiges und kompetentes Handeln des Kardiotechnikers und des Chirurgen erfordern. Kontinuierliche Kommunikation sowie gegenseitiges Verständnis zwischen Chirurg und Kardiotechniker sind essenziell und deshalb Voraussetzung für den reibungslosen Ablauf von extrakorporaler Zirkulation (EKZ) und auch Operation. Funktionsprinzip, technische Entwicklungen sowie Probleme von HLM und EKZ werden grundlegend dargestellt und näher betrachtet.
Abstract
The extracorporeal circulation (cardiopulmonary bypass, CPB) was first introduced for clinical use in 1953. Since then, CPB has improved significantly in all aspects (including reliability, safety, durability, etc.) due to technical innovations and application of research results into clinical practice. Despite the very high standard of the technical equipment and the safety monitoring devices, perfusion problems still occur and require fast and well-trained actions from both the perfusionist and the surgeon. Communication throughout the procedure, as well as mutual understanding of the needs of perfusionists and surgeons are prerequisites for every cardiac surgery procedure with CPB and are of utmost importance if sudden problems with extracorporeal circulation should come up. This review covers all aspects of CPB, knowledge which should be part of the training program of every cardiac surgeon.
