What is the current stance on vasopressin in modern ACLS guidelines?

• A. Vasopressin is not routinely recommended; epinephrine remains the vasopressor of choice.
• B. Vasopressin is routinely recommended alongside epinephrine.
• C. Epinephrine has been removed from guidelines.
• D. Vasopressin replaces epinephrine as first-line vasopressor.

Answer: (A)

In modern ACLS, the go-to vasopressor during cardiac arrest is epinephrine. The idea behind using a vasopressor in CPR is to constrict blood vessels and raise perfusion pressure to the heart and brain, helping restore circulation. While vasopressin can also cause vasoconstriction through different receptors, large studies have not shown a clear survival or neurological advantage over epinephrine. As a result, vasopressin is not routinely recommended as part of standard ACLS protocols and is not used alongside or in place of epinephrine in routine practice. The emphasis remains on epinephrine as the vasopressor of choice.
