Description

Post-resuscitation care is a critical phase following successful cardiopulmonary resuscitation (CPR), aiming to optimize outcomes for patients who have experienced cardiac arrest. It involves meticulous monitoring and management to prevent secondary brain injury, systemic complications, and organ dysfunction. Key components include maintaining adequate oxygenation, hemodynamic stability, and neurological function. Therapeutic hypothermia or targeted temperature management may be employed to mitigate neurological damage and improve survival rates. Continuous assessment of cardiac rhythm, blood pressure, and oxygen saturation guides interventions to stabilize the patient's condition. Post-resuscitation care also encompasses addressing the underlying cause of cardiac arrest, such as myocardial infarction or electrolyte imbalances, through appropriate medical interventions. Multidisciplinary collaboration involving emergency physicians, intensivists, cardiologists, and neurologists is essential for comprehensive post-resuscitation care.

Résumé

  • Post-resuscitation care addresses the postcardiac arrest syndrome, which includes the unresolved precipitating pathology, anoxic brain injury, myocardial dysfunction, and systemic ischemia/reperfusion. Identifying and treating the underlying cause of the arrest is critical, following the "Hs and Ts" mnemonic.
  • Anoxic brain injury results from decreased cerebral blood flow during the arrest, potentially causing neurocognitive dysfunction, seizures, and myoclonus. Fever, hypo/hyperglycemia, and hyperoxia can worsen brain injury, so secondary brain injury prevention is crucial.
  • Myocardial dysfunction, often presenting as global hypokinesia and decreased ejection fraction, is common even with normal coronary flow. Initial tachycardia and hypertension may transition to hypotension, requiring careful blood pressure monitoring.
  • Systemic ischemia and reperfusion lead to lactate release, inflammatory mediators, and potential hyperkalemia, mimicking sepsis. Post-arrest management involves identifying and treating the underlying cause, managing airway, breathing, and circulation.
  • Targeted temperature management (TTM) between 32-36°C aims to reduce cerebral oxygen demand and mitigate reperfusion injury. Shivering must be controlled with sedation and paralysis, which necessitates EEG monitoring for seizure detection.
  • Investigations like chest X-rays, echocardiograms, and ECGs are essential to assess lung condition, cardiac function, and potential ischemia. Consider arterial lines for real-time blood pressure monitoring, targeting a MAP above 65 mmHg.
  • During rewarming, maintaining an electrolyte balance especially potassium is very important to keep a close eye on, and avoiding hyperthermia. After reaching normothermia, neuroprognostication involving clinical examination, MRI, EEG, and biomarkers like neuron-specific enolase can assess neurological recovery.
