The complexities of polypharmacy are a challenge to the intensivist and any guidance as to which drugs to use when to use them and how much to use is always welcome. Happily therefore over the past 2 months a number of interesting papers and articles have appeared covering drugs both new and old. Cardiac arrest in the community is associated with a very high mortality rate. Ventricular fibrillation VF is both the most common mode of arrest and carries the best prognosis if early defibrillation is available 1 . However a subgroup of patients with VF are resistant to direct current defibrillation in which case an antiarrythmic agent is required but very few randomized controlled trials RCTs have been conducted to verify the efficacy of any particular agent. Dorian and colleagues 2 compared lidocaine with amiodarone in the management of out-of-hospital shockresistant VF. In a double-blind RCT 347 patients were randomly assigned to either lidocaine mg kg or amiodarone 5 mg kg as an initial dose. In addition a further and mg kg respectively were given if required. The primary end-point was survival to hospital. A total of 41 patients in the amiodarone group and 20 patients in the lidocaine group survived to hospital P odds ratio 95 confidence interval . .
