Zusammenfassung

Anästhesisten werden durch den steigenden Einsatz von Phytopharmaka vermehrt mit diesen Medikamenten konfrontiert. Im vorliegenden Fallbericht wird am Beispiel von Silexan demonstriert, welche möglichen Probleme entstehen können. Silexan ist ein pflanzliches Anxiolytikum, das zur Therapie von Unruhezuständen und ängstlicher Verstimmung eingesetzt wird. Aufgrund seines potenziellen Wirkmechanismus über γ-Aminobuttersäure- (GABA-)Rezeptoren ist eine Interaktion mit Narkosemedikamenten möglich. Es wird der Fall einer 18-jährigen Frau beschrieben, die sich während der dauerhaften Einnahme von Silexan einer Operation in Vollnarkose unterzog. Dabei konnte die gewünschte Narkosetiefe, nach erfolgloser i.v.-Hypnoseinduktion mit Propofol und Thiopental, erst durch Anwendung einer inhalativen Sevofluraneinleitung erreicht werden. Mögliche Erklärungswege und Gründe für die inhalative Einleitung als mögliche Alternative werden diskutiert.

Abstract

The increased use of phytotherapeutic drugs means that anesthetists are more often confronted with these drugs. In this case report possible problems which can occur are demonstrated exemplified by silexan. Silexan is a phytotherapeutic anxiolytic which is used in anxiety disorders. Because of its potential mechanism of action via the neurotransmitter gamma-aminobutyric acid (GABA) receptors interactions with narcotic drugs are possible. The case of an 18-year-old girl who underwent an operation under general anesthesia while taking silexan as long-term medication is presented. The desired depth of narcosis could only be reached by inhalative induction with sevoflurane after unsuccessful induction attempts using intravenous propofol and thiopental. Possible explanations for this route and inhalative induction as a possible alternative are discussed.
