简要总结
Almost all patients with refractory cardiac arrest, who are primarily stabilized under ongoing cardiopulmonary resuscitation by transcutaneous implantation of a venoarterial extracorporeal membrane oxygenation system (va-ECMO for eCPR) develop post-cardiac arrest syndrome (PCAS). PCAS is characterised by cytokine storm resulting in vasodilation and membrane leakage, which is poorly controlled and often fatal. Case reports and data from the investigators' single-center registry indicate that cytokine adsorption with the CytoSorb removal column can be safely added to va-ECMO, but its efficacy and safety have not been examined systematically. This pilot study will assign all comers undergoing eCPR to va-ECMO with or without cytokine adsorber in a 1:1 fashion. This will ensure comparability and allow analysing clinical endpoints, but is limited by sample size (according to their experience the investigators expect approximately 20 cases per year). The investigators will however be able to generate important data about safety, secondary endpoints such as Interleukin-6-removal or vasopressor use and low-power data about efficacy concerning the primary endpoint 30-day survival.
详细描述
Survival after out-of-hospital cardiac arrest (OHCA) as well as intra-hospital cardiac arrest (IHCA) is poor and remains on low levels over the past decades. Introduction of eCPR has promised to improve survival, however, so far there is no supporting data for this claim. In a recent registry study at the investigators' hospital they determined survival rates of 8.5% (OHCA) and 18.9% (IHCA), respectively. Almost all patients with refractory cardiac arrest, who are primarily stabilized under ongoing cardiopulmonary resuscitation by transcutaneous implantation of a veno-arterial extracorporeal membrane oxygenation system (va-ECMO for eCPR) develop post-cardiac arrest syndrome (PCAS). PCAS is characterised by cytokine storm resulting in vasodilation and membrane leakage, which is poorly controlled and often fatal. Case reports and data from the investigators' single-center registry indicate that cytokine adsorption with the CytoSorb removal column can be safely added to va-ECMO, but its efficacy and safety have not been examined systematically.
First, the investigators aim to assess the influence of treatment with the CytoSorb removal column over 72 hours after cardiac arrest and resuscitation using eCPR on 30-day-survival. As secondary endpoints, the investigators will assess the efficacy of Interleukin-6-removal, vasopressor-use and fluid-substitution, the latter two as a subsidiary of the degree of PCAS. Finally, the investigators will asses the safety of the use of the CytoSorb column in eCPR/va-ECMO.
The investigators hypothesize that the use of the CytoSorb column in eCPR/va-ECMO is a safe and efficient means to manage the consequences of PCAS and thus reduce 30-day mortality after eCPR.
All patients admitted to the investigators' hospital after successful CPR and implantation of va-ECMO/ ECLS (extracorporeal life support, eCPR) will be included in the trial. In a 1:1 manner participants will be assigned to the intervention and control groups.
