According to Resuscitation Council (UK) Resuscitation Guidelines 2015, the following are used in the management of refractory ventricular fibrillation?

True / False

Bretylium Correct

Adenosine Correct

Lidocaine Correct

Amiodarone Correct

Epinephrine Correct

Explanation

Ventricular fibrillation (VF) is always associated with cardiac arrest, and together with pulseless ventricular tachycardia (VT), is a shockable rhythm.

1 mg of epinephrine should be given to all adult patients in VF every three to five minutes. An intravenous bolus of amiodarone (300 mg made up to 20 ml with 5% dextrose) is currently the drug of choice, and can be given in refractory VF or pulseless VT after the third shock.

1 mg/kg of lidocaine may be given intravenously when amiodarone is unavailable. Previously 5 mg per kg of bretylium was given, but this is no longer recommended by the European Resuscitation Council (ERC).

Adenosine blocks the atrio-ventricular node (AVN) and is used to slow the ventricular rate in patients with a narrow complex tachycardia (or supraventricular tachycardia). It has no role in the management of refractory VF.
