What are the immediate recommendations for post-cardiac arrest care?

Post-Cardiac Arrest Care

Post-cardiac arrest care must begin immediately after return of spontaneous circulation (ROSC) with a systematic, bundled approach focusing on hemodynamic optimization, targeted temperature management, identification and treatment of the underlying cause, and prevention of secondary brain injury—all coordinated through a multidisciplinary intensive care system. 1

Immediate Priorities Upon ROSC

Establish Comprehensive Monitoring

The foundation of post-cardiac arrest care requires immediate establishment of monitoring systems to guide all subsequent interventions 2:

• Continuous cardiac telemetry and pulse oximetry 2
• Quantitative capnography to monitor ventilation and detect changes in perfusion 2
• Intra-arterial blood pressure monitoring (arterial line placement when possible) for continuous, accurate hemodynamic assessment 2
• Core temperature monitoring (esophageal, bladder, or rectal) 2
• Point-of-care glucose testing and continuous monitoring 2
• Serial arterial blood gases (pH, PaO2, PaCO2) and serum lactate 2
• Central venous oxygen saturation (ScvO2) and central venous pressure monitoring 1
• Chest radiograph to assess endotracheal tube position, heart size, and pulmonary status 2

Hemodynamic Optimization (First 6 Hours Critical)

Target mean arterial pressure (MAP) ≥65 mmHg within the first 6 hours using goal-directed therapy, as cardiovascular failure accounts for most deaths in the first 3 days. 1

Fluid resuscitation approach 1:

• Administer 1-2 L IV bolus of normal saline or lactated Ringer's for hypotension (SBP <90 mmHg)
• Target central venous pressure >12 mmHg through intravascular volume expansion
• Achieve ScvO2 >70% within 6 hours

Vasopressor/inotrope support if fluid resuscitation inadequate 1:

• Use vasopressors (norepinephrine first-line) to maintain MAP ≥65 mmHg
• Consider dobutamine for persistent shock despite adequate MAP

Airway and Ventilation Management

Establish advanced airway with endotracheal intubation or supraglottic device and confirm placement using waveform capnography. 1

Oxygenation targets 1:

• Titrate inspired oxygen to achieve arterial oxygen saturation of 94%
• Avoid both hypoxemia AND hyperoxemia—maintain SpO2 ≥94% but <100%
• Use facemask if saturation <94% for patients requiring supplemental oxygen only

Ventilation targets 1:

• Target normocapnia: PETCO2 35-40 mmHg or PaCO2 40-45 mmHg
• Start at 10-12 breaths/min and titrate to target
• Avoid excessive ventilation, which impedes venous return and decreases cardiac output

Targeted Temperature Management (TTM)

Initiate targeted temperature management immediately for all comatose survivors of cardiac arrest. 1

Temperature protocol 1:

• Control body temperature to 32-34°C (therapeutic hypothermia) for comatose patients
• Maintain target temperature for 24 hours
• Prevent hyperthermia/pyrexia, which exacerbates brain injury
• Use cooling devices with continuous core temperature monitoring

Sedation during TTM 1:

• Provide deep sedation when neuromuscular blockade is used to prevent shivering
• Be aware that neuromuscular blockade can mask clinical manifestations of seizures
• Avoid excessively deep or prolonged sedation, as it delays neuroprognostication

Identify and Treat Underlying Cause

Acute Coronary Syndrome Management

Perform early coronary angiography for patients with suspected cardiac cause and ST-segment elevation on ECG. 1

• Transport patients to facilities with percutaneous coronary intervention (PCI) capabilities 1
• Consider early angiography even without ST-elevation if cardiac etiology suspected 1

Systematic Evaluation of Reversible Causes

Evaluate and treat the H's and T's 1:

• Hypovolemia, hypoxia, hydrogen ion (acidosis), hypo/hyperkalemia
• Tension pneumothorax, tamponade, toxins, thrombosis (coronary and pulmonary)

Prevent Secondary Complications

Neurological Protection

Avoid all factors that exacerbate brain injury 1:

• Hypotension (maintain MAP ≥65 mmHg)
• Hypercarbia and hypoxemia
• Hyperoxemia
• Pyrexia (strict temperature control)
• Hypoglycemia and hyperglycemia

Seizure management 1:

• Monitor for and treat seizures
• Consider continuous EEG monitoring in comatose patients 2
• Treat if EEG shows evidence of seizure or epileptiform activity

Metabolic Management

Maintain normoglycemia, as both hypoglycemia and hyperglycemia worsen brain injury. 1

• Monitor blood glucose frequently (point-of-care testing) 2
• In pediatric patients, expect hyperglycemia in first 12-18 hours post-arrest, then normalization 2
• Provide appropriate nutrition support 1

Additional Monitoring and Support

Laboratory monitoring 2:

• Serum electrolytes, creatinine, complete blood count, coagulation profile
• Evaluation of renal function
• Assessment for signs of inflammation and infection

Neurological monitoring 2:

• Serial neurological clinical examinations
• Continuous EEG when indicated
• Brain CT or MRI for prognostication and identifying structural injury

Echocardiography 2:

• Assess for post-cardiac arrest myocardial dysfunction (peaks in first 24 hours, typically recovers by 2-3 days) 1
• Identify mechanical complications

Systems of Care Approach

Transport patients to comprehensive post-cardiac arrest treatment centers with capabilities for acute coronary interventions, neurological care, and goal-directed critical care. 1

• Implement multidisciplinary early goal-directed therapy protocols as a bundle of care rather than single interventions 1
• A coordinated and integrated response from prehospital, emergency department, and ICU settings improves outcomes 2
• Approximately 95% of pediatric in-hospital cardiac arrest occurs in an ICU, emphasizing the need for prepared systems 2

Neuroprognostication

Delay prognostication and use multimodal assessment to avoid self-fulfilling prophecy. 1

• Consider effects of drug accumulation during TTM on neurological assessment 1
• Use structured protocols for objective assessment of prognosis 1
• Integrate clinical examination, imaging (brain MRI), and EEG findings 2

Common Pitfalls to Avoid

• Delaying initiation of TTM—must begin immediately for comatose survivors 1
• Hyperoxia—titrate oxygen to SpO2 94%, not 100% 1
• Excessive ventilation—causes decreased venous return and cardiac output 1
• Inadequate hemodynamic monitoring—arterial line placement is critical 2
• Premature neuroprognostication—especially during TTM when sedation confounds examination 1
• Failure to identify and treat underlying cause—systematic evaluation essential 1
• Isolated interventions rather than bundled care—comprehensive protocols improve outcomes 1, 3
