Allocation: RANDOMIZED | Intervention model: PARALLEL
Enrollment: 727
Healthy volunteers: no

Brief summary:
The effectiveness of medications in cardiac arrest has been greatly debated and questioned. Historically intravenous adrenaline has been the drug of choice since 1906. There have been few formal evaluations to determine the value of adrenaline for cardiac arrest, and clinical trials have not been able to show any benefit with intravenous adrenaline (compared to placebo or no treatment) in the field.

Thus the purpose of this study is to compare vasopressin and adrenaline in the treatment of cardiac arrest to answer the question whether there is an improvement in survival between vasopressin and adrenaline.

Detailed description:
The effectiveness of medications in cardiac arrest has been greatly debated and questioned. Historically intravenous adrenaline has been the recommended drug of choice since 1906. There have been few formal evaluations to determine the value of adrenaline for cardiac arrest, and clinical trials have not been able to show any benefit with intravenous adrenaline (compared to placebo or no treatment) in the field.

More recently, vasopressin has been used in patients with cardiac arrest. In human studies on vasopressin, clinical trials have produced conflicting results.

The current study compared vasopressin and adrenaline in the treatment of cardiac arrest in patients presenting to the Emergency Department (ED). Specific outcomes included return of spontaneous circulation (ROSC) (as measured by the presence of a palpable pulse at any time during resuscitation), survival to hospital admission, survival to discharge from hospital, and functional status at discharge and at one year (as measured by the Glasgow-Pittsburgh outcome categories).
