PCI can also be considered if there is a suitable receiving centre available and the patient can be delivered in a safe and timely fashion. Other potential interventions not in the guidelines include IV magnesium and placing defibrillator pads in the anterior-posterior orientation. I was faced with this situation when called to support an ambulance crew who were resuscitating an out-of-hospital VF arrest. When benchmarked against the ALS guidelines their management had been exemplary, but the patient remained in VF after eight shocks. So what now? The UK Resuscitation Council doesn’t specifically discuss rVF, but offers the advice that it is “usually worthwhile continuing” if the patient remains in VF. Not a particularly controversial statement, but not much help either. They do discuss the potential for ECMO use, but this is currently a very rare option in UK practice, or thrombolysis for known or suspected pulmonary embolism. If this is the case then the management of cardiac arrest, which is taught and delivered in a didactic and protocol driven fashion, is surely the pinnacle of the problem. Standard Advanced Life Support (ALS) is totally appropriate for the majority of cardiac arrests, but what happens when it fails our patients? Refractory ventricular fibrillation (rVF) is, by its very nature, defined by the failure of ALS, but frustratingly there is very little evidence, or guidance, surrounding how to manage this patient group. Guidelines encourage inflexible decision making, which creates further challenge when we are met by patients who do not fit standard treatment pathways. Evidence based medicine. These all play a significant part in the safe and effective management of the majority of our patients. As a result there is a danger that treatment pathways are followed blindly without critiquing their use and there is real risk we can loose sight of what’s best for the patient in front of us.
