Target-directed Management of Cerebral Oxygenation in Patients After Receiving ECPR
Sponsor: Qilu Hospital of Shandong University
Summary
Neurological injury remains an important cause of morbidity and mortality in patients with ECPR. At present, the results of three prospective randomized controlled studies on ECPR are inconsistent, and it is inconclusive whether ECPR can improve the neurological outcomes of patients with refractory cardiac arrest. Several study found that extracorporeal membrane oxygenation nonsurvivors can lead toacute brain injury.Further research with a systematic neurologic monitoring is necessary to define the timing of acute brain injury in patients with extracorporeal membrane oxygenation.Moreover, brain injury that occurs during extracorporeal membrane oxygenation therapy is not easy to detect in time because of the use of analgesics, sedatives, and muscle relaxants. Surprisingly, little attention has been paid to the role of cerebral perfusion and oxygenation. Moreover,the features of cerebrovascular pathophysiology and optimal management strategies are still vague. Therefore multimodal neuromonitoring may be a valuable tool for detecting brain injury in patients with extracorporeal membrane oxygenation and providing early intervention guidance. Multimodal neuromonitoring, integrating tools such as near-infrared spectroscopy (NIRS), transcranial Doppler, and continuous electroencephalography, may enable early detection of brain injury and guide targeted interventions. Hypothesis: Multimodal neuromonitoring combined with a standard care management will increase the proportion of patients achieving survival with favorable neurological outcome (Cerebral Performance Category \[CPC\] 1-2) at 30 days compared with standard care without protocolized neuromonitoring. Primary Objective: To test whether a multimodal neuromonitoring strategy improves 30-day survival with favorable neurological outcome (CPC 1-2) in adult patients with refractory cardiac arrest treated with ECPR.

Conditions
Interventions
if rSO2 < 58%
Use Vasoactive drugs(MAP 65-95mmHg); Use Cardiotonic agents(CO 3.0-4.5L/min); Increase ECMO blood flow rate(Vm 55-85cm/s); Osmotic dehydration therapy(Na+ 140-150mmol/l;Osmotic pressure 280-320m0sm/(kg·H₂O);ONSD\<5.5mm); Antiepileptic therapy(EEG shows no seizures); Optimize sedation and analgesia; Target Temperature Management
if rSO2 58%-68%
Optimize ECMO blood flow rate( Vm 55-85cm/s); Osmotic dehydration therapy(Na+ 140-150mmol/l;Osmotic pressure 280-320m0sm/(kg·H₂O);ONSD\<5.5mm); Optimize sedation and analgesia; Antiepileptic therapy(EEG shows no seizures); Target Temperature Management
rSO2>68%
Antihypertensive therapy(MAP ≥65mmHg); Inhibiting myocardial contractility and controls ventricular rate(CO 2.5-3.0 L/min); Decrease ECMO blood flow rate(Vm 55-85cm/s); Osmotic dehydration therapy(Na+ 140-150mmol/l;Osmotic pressure 280-320m0sm/(kg·H₂O); Antiepileptic therapy(EEG shows no seizures); Optimize sedation and analgesia; Target Temperature Management
Standard monitoring based on ECPR, along with continuous cerebral oxygenation monitoring (blinded to investigators, with no clinical interventions according to the results).
Clinical interventions are strictly guided by the 2023 American Heart Association (AHA) Guidelines for Advanced Cardiovascular Life Support in Adults (hereinafter referred to as the 2023 AHA Guidelines), including regulating ECMO blood flow, the dose of vasoactive drugs (MAP ≥65 mmHg), mechanical ventilation parameters (SaO₂ 94-98%, PaCO₂ 35-45 mmHg), sedation and analgesia plans. Concurrently, staged target temperature management is implemented, involving maintaining the core temperature 32- 37.5°C within 24 hours, initiating controlled rewarming at a rate of ≤0.1°C/h after 24 hours, and continuing to prevent fever (core temperature ≤37.5°C) within 72 hours.
