Compression Is Life In Cardiac Arrest - Human Study (CILICA-HS).

Summary

The management of out-of-hospital cardiac arrest is complex and multifactorial. With an incidence between 5 and 15 per 10,000 (46,000 patients per year in France) and a survival rate of only 5% to 15%, the room for improvement remains significant even today and is based on fast and optimal care. Thus French and international recommendations insist on the central element of external chest compression (ECC) and especially its quality (Monsieurs KG and Al. Resuscitation 2015; 95: 1-80). Improving the chest compression fraction (CCF) by limiting time without cardiac massage (No-Flow) is a second major point of the recommendations (Vaillancourt C and Al. Resuscitation 2011; 82: 1501-7). The survival of cardiac arrest victims is closely related on this No-Flow time. The principle of the chain of survival (early warning - ECC - defibrillation - resuscitation) implies that the deterioration of a single link threaten the whole of the care. To meet these qualitative needs, ECC guidance devices have been developed. They make possible to improve the quality of the ECC achieved (Hostler D and Al. BMJ 2011; 342d512). Their use is one of the areas of improvement mentioned in the recommendations. Our team studied in simulation the prolonged effects of guidance on the quality of the ECC during a prolonged resuscitation, with encouraging results (Buléon C and Al. Am J Emerg Med 2016; 34: 1754-60). The investigators propose a study evaluating the efficiency of the guidance of the ECC and the impact of the time of relay on the CCF. The investigators formulate two hypotheses that they wish to test simultaneously using a 2x2 factorial design, in a multicenter randomized trial. The first assumption is that a 4-minute relay rate improves the CCF (by reducing the No-Flow time) compared to the currently recommended 2-minute relay rate. The second hypothesis is that a guiding device improves the quality of the ECC.

This study should, over a period of 2 years, include 500 patients with cardiac arrest for whom specialized resuscitation is undertaken. The investigators hope by this study to improve the knowledge on the optimal rhythm of the ECC and to validate "in vivo" the interest for the guidance found on manikin. This study should make it possible to clarify the recommendations with a high level of evidence in this field and thus contribute to improving the prognosis of the victims of an out-of-hospital cardiac arrest.

Conditions

• Cardiac Arrest
• Cardiopulmonary Resuscitation

Interventions

OTHER

Rhythm of a relay 4 minutes

The duration or rhythm of a relay is the time during which a rescuer performs External Chest Compression before being relayed by another rescuer. This time is 2 minutes in non intervention group according to the current guidelines and 4 minutes in experimental group.

OTHER

Guidance of the External Chest Compression

The CPRmeter® device is positioned on the patient's chest with a disposable adhesive. In the situation of guidance of the External Chest Compression the rescuers have access in real time on the screen to visual feedback on the quality of the External Chest Compression performed and indications of possible corrections to improve the quality of the External Chest Compression . In the case of non-guidance of the External Chest Compression , a mask is position on the screen in order to hide the feedback information.
