A national survey of medication utilization for cardiac resuscitation in the emergency department: A survey of emergency medicine pharmacists

Purpose: Vasoactive medications are used during advanced cardiac life support (ACLS) to shunt oxygenated blood to vital organs and after return of spontaneous circulation (ROSC) to maintain hemodynamic goals. However, limited evidence exists to support vasoactive medication recommendations in such scenarios, and it is unknown how practices vary among emergency departments across the US.

Methods: A survey questionnaire (15 questions) was electronically distributed to emergency medicine pharmacists (EMPs) in the US through various professional listservs. Demographic information, American Heart Association ACLS algorithm medication use, and use of continuous vasopressor infusions and adjunct medications following ROSC were assessed and are reported descriptively.

Results: The survey was distributed to 764 EMPs, with a 23% response rate from a wide geographic distribution and 48% of respondents practicing in academic medical centers. Epinephrine dosing and administration during cardiac arrest were reported by most to be in accordance with ACLS cardiac arrest algorithms. Calcium, magnesium sulfate, and sodium bicarbonate were the most common adjunct intravenous medications given during cardiac arrest. Norepinephrine was the first-choice vasopressor (81%) for post-ROSC hypotension, while epinephrine was preferred less frequently (17%). Antibiotics and sodium bicarbonate were the most frequently administered post-ROSC adjunct medications.

Conclusion: This survey of a geographically diverse group of EMPs demonstrated high ACLS algorithm adherence for epinephrine during cardiac arrest with frequent additional administration of nonalgorithm medications. Sodium bicarbonate and calcium were the most frequently administered adjunct medications during cardiac arrest, while sodium bicarbonate and antibiotics were the most frequently used adjunct medications following ROSC. Norepinephrine was the most commonly used vasopressor following ROSC.
