The Resuscitation Outcomes Consortium
Amiodarone, Lidocaine, Placebo Study (ALPS)
Overview (page 2)
The purpose of this study is to determine whether the use of certain heart rhythm medications will improve the chances of patients surviving to hospital discharge following a cardiac arrest outside of the hospital. This study will test whether more patients are discharged alive from the hospital when given the heart rhythm medication Amiodarone compared to Lidocaine (another heart rhythm medication) or neither medication, that is, something called a placebo. The placebo is a solution (made up of salt water) that looks like the study drug but has no medicine in it. Before this study begins, participating agencies who respond to emergency calls will be instructed on how the study is done, and treat the patient according to the study plan that is described below. Amiodarone and Lidocaine are frequently used as part of advanced care to treat heart arrhythmias that persist or recur during a cardiac arrest. Heart rhythm medications are used with the hope that they can help stabilize the heart after it has been successfully restarted following an electrical shock. In a prior study, Amiodarone was better than Lidocaine in improving short term outcomes (survival to hospital admission), but not long term outcomes (survival to hospital discharge). This study will give insight into which of these medications are most effective, or if they, in fact, do more harm than good.
Normally, before someone joins a research study, it is discussed with him or her in detail. Also, a consent form that lists the purposes of the study, the possible benefits, and the risks from being in the study is reviewed with the person. If the person agrees to join the study, the consent form is signed. In most cases, this takes place before any study procedures are done or treatment is given. This process is called "informed consent" and ensures that the person volunteered for the research study only after being given the information necessary to make an informed decision.
For this study, investigators will not be able to get written informed consent from each study participant, due to them being unconscious while in cardiac arrest. Instead, the investigators will try to inform the community about the study and address any concerns or questions before the study is approved to begin. We will do this by:
- This website
- Community meetings
- Online and mailed surveys
- Newspapers and Newsletters
or the ALPS OHSU Press release.
