Epinephrine, a hormone and medication, extends anesthetics' duration by constricting blood vessels, affecting a- and ß-adrenergic receptors.
Epinephrine, also known as adrenalin or adrenaline, is a hormone and medication used to treat various conditions such as anaphylaxis, cardiac arrest, and asthma. It can be administered through inhalation, intravenous injection, or subcutaneous injection.
Epinephrine prolongs the duration of action of anesthetics like propofol by constricting blood vessels, which in turn delays the absorption of the anesthetic into the bloodstream, extending its effect.
The effects of epinephrine in the body involve interaction with a- and ß-adrenergic receptors, which trigger physiological responses such as increased heart rate, bronchodilation, and improved oxygen transport.
