Resuscitation

To describe our outcomes using thrombolysis during the cardiopulmonary resuscitation (CPR) of patients in cardiorespiratory arrest (CA) caused by fulminant pulmonary embolism (FPE). ⋯ Early thrombolysis during CPR manoeuvres for CA apparently caused by an FPE may reduce the mortality rate among these patients.

Electrode polarity may alter the success of biphasic shocks from implantable systems. Whether the electrode polarity influences the success of transthoracic biphasic defibrillation is unknown. We determined the effect of electrode polarity on biphasic transthoracic defibrillation in a porcine model. ⋯ In this porcine model of transthoracic defibrillation, varying the biphasic shock electrode polarity did not alter transthoracic defibrillation success. Positional labeling of transthoracic biphasic defibrillation electrode pads may be unnecessary.
-
To describe the epidemiology, resuscitation factors and prognosis among a consecutive population of patients suffering from out-of-hospital cardiac arrest (OHCA) where pulseless electrical activity (PEA) was the first arrhythmia recorded on emergency medical services (EMS) arrival. ⋯ Survival among patients suffering from OHCA and PEA is poor, especially among the elderly unwitnessed cases and those who do not receive bystander CPR. The latter seems to be of utmost importance among these patients.

The components of the 'chain of survival' remain the strongest pathway to save more people from out-of-hospital cardiac arrest. The 'Utstein Style' terminology has been applied to this study to evaluate survival in patients cared for by Emergency Medical Technicians--Defibrillation (EMT-D) and physicians in a rural alpine area. ⋯ With the exception of publications on avalanche victims and mountaineers, there are no reports of patients with out-of-hospital cardiac arrest in alpine areas. Response intervals and survival rate are not as poor as might be expected and are similar to metropolitan areas.

Spontaneous subarachnoid haemorrhage as a cause of out-of-hospital cardiac arrest is poorly evaluated. We analyse disease-specific and emergency care data in order to improve the recognition of subarachnoid haemorrhage as a cause of cardiac arrest. ⋯ Subarachnoid haemorrhage complicated by cardiac arrest is almost always fatal even when a spontaneous circulation can be restored initially. This is due to the severity of brain damage. Subarachnoid haemorrhage may present in young patients without any previous medical history with cardiac arrest masking the diagnosis initially.
