Post-Resuscitation Care

Post-resuscitation care begins immediately after a patient regains spontaneous circulation (ROSC) following cardiac arrest. This phase is vital for stabilizing the patient, preventing further damage, and improving long-term survival and quality of life. While the goals are similar for adults and pediatrics—supporting organ function and identifying the cause of arrest—differences arise due to physiological variations and the typical causes of arrest in each group.



 
 Post-Resuscitation Care for Adults

For adults, guidelines from the European Resuscitation Council (ERC) outline a structured approach to care. Consider transport to a recognized center (e.g., cardiac arrest center) for out-of-hospital cardiac arrest (OHCA).

  • Airway and Breathing:
    • Ensuring adequate oxygenation by titrating oxygen to achieve SpO2 94-98% and using mechanical ventilation with lung-protective strategies if needed.
    • Comatose patients or those needing sedation/mechanical ventilation should have trachea intubated by
    • experienced operators, confirmed with waveform capnography.
    • Avoid hypoxemia (PaO2 < 8 kPa or 60 mmHg) and hyperoxemia.
  • Circulation: 
    • Monitoring blood pressure continuously, targeting a mean arterial pressure (MAP) > 65 mmHg, and considering coronary angiography for cardiac causes.
    • Early echocardiography to detect cardiac pathology and quantify dysfunction.
    • Avoid hypokalaemia (associated with ventricular arrhythmias).
    • Consider mechanical circulatory support (e.g., intra-aortic balloon pump, LVAD, ECMO) for cardiogenic shock or recurrent VT/VF despite optimal therapy.
  • Neurological Care: 
    • Preventing fever (>37.7°C) for at least 72 hours in comatose patients and using EEG for seizure management.
    • Treat seizures with levetiracetam or sodium valproate as first-line, in addition to sedatives.
    • Do not use routine seizure prophylaxis.
  • Long-Term Support: 
    • Assessing functional outcomes before discharge and organizing follow-up within 3 months for cognitive and emotional support.
    • Screening for cognitive problems.
    • Screening for emotional problems and fatigue.
    • Provide information/support for survivors and families

An unexpected detail is the use of levetiracetam or sodium valproate as first-line antiseizure medications, moving away from older options like phenytoin, reflecting recent updates in practice.

Post-Resuscitation Care for Pediatrics

For children, the American Heart Association (AHA) 2020 guidelines highlight the importance of post-arrest care, especially for those not regaining consciousness. Key aspects include:

  • Brain Protection: Using targeted temperature management (TTM) and continuous EEG monitoring to prevent secondary brain injury.
  • Preventing Complications: Avoiding hypotension, hyperoxia, hypoxia, hypercapnia, and hypocapnia, with strict monitoring of oxygenation.
  • Long-Term Care: Addressing potential physical, cognitive, and emotional challenges through ongoing therapies and follow-up.

An interesting difference is that pediatric arrests are often secondary to respiratory failure or shock, unlike the cardiac focus in adults, which shapes the care approach.

Challenges and Knowledge Gaps

Both adult and pediatric post-resuscitation care face challenges, with several knowledge gaps identified:

Adults: Optimal blood pressure targets during post-resuscitation care remain debated, with current guidelines suggesting MAP >65 mmHg but acknowledging individual variation. The role of prophylactic antiseizure medications is also under review, with no routine recommendation. Long-term rehabilitation strategies to improve functional outcomes are another area needing further research.

Pediatrics: Similar debates exist around optimal blood pressure targets, with age-specific norms adding complexity. The role of seizure prophylaxis and whether treatment of post-arrest seizures improves outcomes are unresolved. Reliable methods for early prognostication and effective rehabilitation therapies tailored to children are also critical areas for future study.

Conclusion

Post-resuscitation care is an evolving field with significant implications for patient outcomes. For adults, the ERC guidelines provide a structured approach focusing on airway management, circulation support, neurological protection, and long-term rehabilitation. For pediatrics, the AHA guidelines emphasize preventing brain injury through TTM and addressing non-cardiac causes, with a focus on long-term support for survivors. Healthcare providers must stay informed about the latest guidelines from authoritative sources like the ERC (European Resuscitation Council Guidelines) and AHA, ensuring evidence-based care as research progresses.
