ACLS and the use of antiarrhythmic agents

Here's a new systematic review published in the journal Resuscitation. The conclusions were in line with the current recommendations:

Amiodarone may be considered for those who have refractory VT/VF, defined as VT/VF not terminated by defibrillation, or VT/VF recurrence in out of hospital cardiac arrest or in-hospital cardiac arrest. There is inadequate evidence to support or refute the use of lidocaine and other antiarrythmic agents in the same settings.
