[New aspects and perspectives on cardiac arrest]

Area of Science:

• Cardiology
• Emergency Medicine
• Critical Care Medicine

Context:

• Current knowledge on cardiopulmonary resuscitation (CPR) is based on experimental and clinical research.
• International guidelines and review articles are key resources for understanding CPR advancements.
• The Medline database was searched using the keyword 'cardiac arrest' for relevant studies.

Purpose:

• To analyze current knowledge in cardiopulmonary resuscitation (CPR) based on experimental and clinical research.
• To review studies published in the last ten years focusing on CPR advancements.
• To identify clinical information that has influenced CPR guidelines.

Summary:

• Promising improvements in basic and advanced life support are proposed, with chest compressions prioritized over ventilation.
• Recommended ventilatory volume is reduced to approximately 500 mL per breath with oxygen.
• Biphasic waveform defibrillators and automated external defibrillators are considered future best devices.
• Amiodarone may replace lidocaine as the preferred anti-arrhythmic drug, and non-catecholaminergic vasopressors might reduce epinephrine use.
• New post-resuscitation strategies, including coronary reperfusion for cardiac arrest, are under evaluation.

Impact:

• Findings suggest potential updates to CPR guidelines, though further research is necessary before widespread implementation.
• The review highlights key areas of CPR investigation, informing future research directions.
• This analysis provides a foundation for evidence-based practice in emergency cardiac care.
