727The 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.
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).

Survival to hospital discharge is defined as the patient leaving the hospital alive or survival to 30 days post cardiac arrest,whichever came first. This therefore measures the number of participants who was discharged alive or survived to 30 days post cardiac arrest, whichever came first.
Neurological status is assessed by the Glasgow-Pittsburgh outcome categories, to evaluate quality of life after successful resuscitation. Good neurological status is defined as cerebral performance categories(CPC)/overall performance categories(OPC):1 and 2.CPC/OPC 1 indicates good cerebral & overall performance. CPC/OPC 2 indicates moderate cerebral & overall disability. CPC/OPC 3 indicates severe cerebral & overall disability. CPC/OPC 4 indicates coma, vegetative state. CPC/OPC 5 indicates brain dead/death.

Return of spontaneous circulation is defined as the presence of any palpable pulse detected by manual palpation of a major artery. This is measured as number of participants who had return of spontaneous circulation during resuscitation.
Survival to admission is defined as the presence of pulse on admission to hospital (discharged from Emergency Department and admitted to Intensive Care Units /wards). This measures the number of participants with pulse and who were admitted to hospital.
