Zusammenfassung
Auch heute ist die Suche nach dem idealen Inhalationsanästhetikum nicht abgeschlossen. Die Mitte der 90er-Jahre in Deutschland eingeführten Inhalationsanästhetika Desfluran und Sevofluran zeichnen sich durch niedrige Blut-Gas-Verteilungskoeffizienten aus. Dies spiegelt sich in günstigen pharmakokinetischen Eigenschaften wieder. Hohe hämodynamische Stabilität ist besonders für Sevofluran zu erwähnen. Als Nachteil einiger Substanzen ist eine potenzielle Organtoxizität zu nennen. Enfluran und Sevofluran zeigen hypothetisch nephrotoxische Eigenschaften. Abbauprodukte im Absorberkalk sind vor allem für Sevofluran (Compound-A-Bildung) sowie Desfluran (CO-Bildung) erwähnenswert. Gegenüber intravenösen Anästhetika zeichnen sich volatile Anästhetika durch kardio- und zerebroprotektive Eigenschaften aus.
Abstract
None of the currently available inhaled anesthetics has all of the properties of an “ideal” inhaled agent. The exceptionally low solubility of desflurane and sevoflurane offers a significantly greater precision of control over maintenance of anesthesia and a potential for a more rapid recovery from anesthesia than other inhaled anesthetics. Sevoflurane appears to offer some advantages regarding cardiovascular stability. Products of metabolism or degradation can be associated with potential organ-specific toxic effects. Renal toxicity is discussed for enflurane and sevoflurane. Breakdown products of volatile agents with carbon dioxide absorbents have to be mentioned especially for sevoflurane (compound A) and desflurane (CO). In contrast to intravenous anesthetics, volatile anesthetics are associated with cardio- and cerebroprotection.
