Summary
Inhaled anesthetics such as ether sensitize the myocardium to catecholamines. Epinephrine given during anesthesia may provoke ventricular tachycardia, other arrhythmias and hypertension.
What this interaction means in plain words
Epinephrine and Ether 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
Myocardial sensitization to catecholamines by the anesthetic, increasing arrhythmogenicity.
What to do
Avoid epinephrine during ether anesthesia where possible, or use minimal doses with continuous ECG and blood pressure monitoring. Have antiarrhythmic treatment available.
What to ask your pharmacist
