Clinical & Economical Interest of Endovascular Cooling in the Management

Status Completed

Clinical Trial Summary

According to international guidelines, mild therapeutic hypothermia is recommended for resuscitated patients after cardiac arrest due to ventricular fibrillation. Whether external or internal cooling is superior in terms of prognosis or security remains unknown. The aim of this study is to evaluate in a randomized trial the clinical and economical interests of the endovascular cooling versus the conventional external cooling for the management of hypothermia after cardiac arrest.

Clinical Trial Description

According to international guidelines, mild therapeutic hypothermia is recommended for resuscitated patients after experiencing cardiac arrest from cardiac origin: "unconscious adult patients with spontaneous circulation after cardiac arrest should be cooled to 32-34°C for 12-24 hours when the initial rhythm was ventricular fibrillation" or pulseless ventricular tachycardia. "Such cooling may also be beneficial for other rhythm or in-hospital cardiac arrest".

"External or internal cooling techniques can be used to initiate cooling within minutes to hours". The two main randomized and positive studies dealing with the efficiency of hypothermia after cardiac arrest have used external cooling systems. However, several animal studies documented the importance of initiating hypothermia as soon as possible after cardiac arrest. Intravascular cooling enables more rapid induction of hypothermia compared with external cooling method after brain injury. Although several human studies have also documented that intravascular cooling provides more precise control of core temperature than external methods and although an endovascular method has been used safely in pilot studies in those experiencing hypothermia after cardiac arrest, the superiority of such a cooling on the prognosis after cardiac arrest remains unknown, as well as its cost efficiency.

The aim of this study is to evaluate in a randomized trial the potential clinical and economical interests of the endovascular cooling versus the conventional external cooling for the management of cardiac arrest from cardiac origin. With a clinical primary endpoint (survival without major neurological sequels), this study will also focus on important secondary endpoints, as the burden of nurse work and the economical costs induced by these 2 different methods of cooling. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
