Summary
Volatile anesthetics sensitize the myocardium to catecholamines, so epinephrine can provoke ventricular arrhythmias. Desflurane is generally considered less arrhythmogenic than halothane, but risk remains.
What this interaction means in plain words
Desflurane and Epinephrine racemic can interact in a way that may be serious. Using them together is sometimes necessary, but it needs a deliberate decision by the prescriber, a plan for monitoring, and clear advice on the warning signs to watch for.
Why it happens
Pharmacodynamic myocardial sensitization to catecholamines by the anesthetic; a metabolic effect is not established.
What to do
Use the lowest effective epinephrine dose with continuous ECG monitoring and be ready to treat arrhythmias.
What to ask your pharmacist
- Does the benefit of taking both outweigh the risk in my case?
- Do I need any blood test, ECG or other check while on both?
- What early warning signs should I watch for, and what should I do if they appear?
