Zusammenfassung
Ein großer und weiter zunehmender Anteil der Patienten, die sich dem Anästhesisten
im Rahmen der Prämedikationsvisite vorstellen, nimmt täglich Medikamente zur Therapie
oder Prophylaxe kardiovaskulärer, pulmonaler und/oder metabolischer Erkrankungen ein.
Viele dieser Medikamente können in der perioperativen Phase pausiert werden. In manchen
Fällen kann das präoperative Absetzen aber auch zur Dekompensation zuvor kompensierter
Erkrankungen führen. Ziel dieses Fortbildungsartikels ist es, dem Leser eine Entscheidungshilfe
für das Absetzen oder Weiterverordnen der präoperativen Dauermedikation bei kardiovaskulären,
pulmonalen und metabolischen Erkrankungen an die Hand zu geben.
Abstract
Almost 50 % of all patients that are evaluated preoperatively by an anesthesiologist
are receiving concurrent medication. Many of the prescribed drugs can be omitted during
the perioperative period. However, perioperative cessation of certain drug therapies
may cause decompensation of primarily compensated diseases. After reading this CME
article, the reader should be able to decide whether any cardiovascular, pulmonary
or antidiabetic drug therapy should be continued or ceased during the perioperative
period, respectively.

Kernaussagen
-
Alle Substanzen zur Therapie der KHK, zur Prophylaxe von Angina–Pectoris–Anfällen
und für Therapie oder Prophylaxe bronchialer Obstruktionen sollen perioperativ weiter
verordnet werden. Hierzu zählen β–Blocker, α2–Agonisten, Ca++–Antagonisten, Nitrate, Statine sowie inhalative β2–Sympathomimitika, Anticholinergika und Kortikosteroide.
-
Innerhalb von 12 Monate nach Einsetzen eines Drug–Eluting–Stents und 4 Wochen nach
Einsetzen eines Bare–Metal–Stents darf eine Thienopyridin–Therapie nicht unterbrochen
werden. Elektive Eingriffe werden verschoben, bis die Thienopyridin–Therapie abgesetzt
werden kann.
-
ASS wird bei Zustand nach instabilem Koronarsyndrom und nach kürzlich implantierten
Koronarstents nur abgesetzt, wenn das Risiko der erhöhten intraoperativen Blutungsneigung
gegenüber dem Risiko einer aufgehobenen Thrombozytenaggregationshemmung überwiegt.
In allen anderen Fällen soll niedrigdosiertes ASS perioperativ weiter verordnet werden.
-
Rückenmarksnahe Regionalanästhesieverfahren können unter Einnahme von niedrigdosiertem
ASS durchgeführt werden, wenn keine gleichzeitige Heparinisierung erfolgt.
-
Über die perioperative Verordnung von ACE–Hemmern, AT1–Blockern und Diuretika muss im Einzelfall entschieden werden.
-
Orale Antidiabetika werden mindestens 12 Stunden vor einem operativen Eingriff abgesetzt,
um perioperative Hypoglykämien zu vermeiden. Biguanide werden 48 h vor einem operativen
Eingriff abgesetzt. Gegebenenfalls wird präoperativ eine Insulin–Therapie begonnen.
