During an advanced cardiac life support (ACLS) situation, what medication is commonly used for managing cardiac arrest?

Adrenaline, also known as epinephrine, is the medication that is commonly used for managing cardiac arrest during advanced cardiac life support (ACLS). In cases of cardiac arrest, particularly in situations of ventricular fibrillation or pulseless ventricular tachycardia, epinephrine plays a critical role in improving coronary perfusion pressure during CPR (cardiopulmonary resuscitation). This is essential for increasing the likelihood of returning spontaneous circulation to the patient.

The administration of epinephrine is recommended within the first few minutes of cardiac arrest and can be given every 3 to 5 minutes during the resuscitation process. Its effects include peripheral vasoconstriction, which helps redirect blood flow to vital organs, notably the heart and brain, enhancing the chances of successful defibrillation or return of spontaneous circulation.

While other medications are used in different scenarios or for specific conditions related to cardiac arrest, such as amiodarone for the management of refractory ventricular fibrillation or tachycardia, adrenaline's role as a first-line intervention during cardiopulmonary resuscitation is fundamental in ACLS protocol.
