What do you expect to happen after administration of a dose of intravenous epinephrine during a resuscitation?

This may enhance the heart rate.

Further Explanation:

Epinephrine is used in delivery room for the resuscitation of the newborn. It is associated with mortality. It is rarely required by the newborn, so this is the uncommon event and those who do require extensive cardiopulmonary resuscitation including epinephrine have high risk of mortality. Those who survives mostly suffer from worst long term neuro-developmental outcome.

Epinephrine is used to stimulate the heart muscle which is deprived of oxygen molecule, increase diastolic pressure, improving the perfusion of the coronary arteries. The epinephrine has periphery vasoconstriction property which in turn enhances the blood flow to the brain and coronary arteries so as to increase the availability of oxygen to the heart.

There are various routes for epinephrine delivery, they are:

1. Intravenous: Most preferred and efficacious route.

2. Endotracheal: Less effective than intravenous.

3. Intraosseous: Limited evidence compared to intravenous route.

4. Intramuscular: It has very limited evidence.
