From the Guidelines
When a patient is resuscitated, the primary goal is to restore spontaneous circulation and ensure the best possible outcome in terms of morbidity, mortality, and quality of life, with recent studies emphasizing the importance of post-resuscitation care, including targeted temperature management and sedation management 1.
Post-Resuscitation Care
The post-resuscitation phase is crucial for patient outcomes, and it involves a range of interventions to support multiple organ systems, as outlined in the European Resuscitation Council and European Society of Intensive Care Medicine 2015 guidelines for post-resuscitation care 1. This includes:
- Providing multiple organ support
- Treating the underlying cause of the cardiac arrest
- Managing the post-cardiac arrest syndrome
- Implementing targeted temperature management (TTM) to mitigate anoxic brain injury
- Using sedation and analgesia to facilitate invasive mechanical ventilation (IMV) and TTM
Sedation and Shivering Management
Sedation management is critical in the post-cardiac arrest population, particularly in patients undergoing TTM, as it requires careful consideration of the choice of sedative agents and the management of shivering, which can be detrimental to patient outcomes 1. Key considerations include:
- Choosing sedative agents that are appropriate for patients undergoing TTM
- Managing shivering to prevent increased metabolic demand and potential worsening of brain injury
- Using a structured approach to sedation and analgesia to minimize the risk of adverse effects
Outcome and Quality of Life
The ultimate goal of resuscitation and post-resuscitation care is to achieve the best possible outcome in terms of morbidity, mortality, and quality of life, with studies suggesting that rapid awakening and recovery are possible in some patients, particularly those with out-of-hospital cardiac arrest 1. Factors that influence outcome include:
- Response times and rates of bystander CPR
- Times to defibrillation and the duration of CPR
- The severity of the post-cardiac arrest syndrome and the effectiveness of post-resuscitation care.
From the Research
Resuscitation Process
When resuscitating a patient, several key steps and considerations come into play. The primary goal of cardiopulmonary resuscitation (CPR) is to maintain perfusion and extend the potential resuscitation period 2. This involves:
- Effective control of the airway using manual maneuvers or airway adjuncts
- Delivery of effective ventilation to assure adequate oxygenation while reducing the chance for gastric inflation
- Chest compressions delivered at the appropriate depth and rate using a duty cycle of 50% compression and 50% release
Ventilation and Oxygenation
Effective management of ventilation and oxygenation during and after CPR is vital for patient survival and neurological outcomes 3. This includes:
- Providing adequate ventilation and oxygenation during and after CPR
- Avoiding hyperventilation and hypoventilation, which can negatively impact resuscitation and post-cardiac arrest outcomes
- Considering the use of mechanical ventilation as an alternative to manual methods and the use of feedback devices
High-Quality Compressions
High-quality compressions remain the foundation of CPR, optimizing coronary and cerebral perfusion pressure 4. This involves:
- Performing compressions at the appropriate rate and depth
- Minimizing interruptions in compressions, as they are detrimental to management
Fluid Resuscitation
In cases of shock or trauma, rapid and intentional intervention to resuscitate can reduce mortality and organ injury 5, 6. This may involve:
- Careful consideration of the type and amount of intravenous fluids to administer
- Using damage control principles and targeted resuscitation to guide fluid administration
- Limiting the use of crystalloids in favor of blood components in severely injured patients
