To evaluate the decision criteria leading to refrain from starting cardiopulmonary resuscitation (CPR) in the prehospital setting. ⋯ Decision criteria leading to refrain from starting CPR in the prehospital setting are age, previous health status and initial BLS. Further thought should be allowed to ensure a share in the decision-making process in this particular practice.

There is an emerging demand for inter-facility transport (IFT) of patients in recent years following changes in the healthcare framework in Hong Kong but this carries certain risks. Anticipation of possible deterioration of patients is important for patient safety and therefore risk stratification of patients before transport is important. ⋯ IFT represents a group of patients with vast heterogeneity. TISS-28 is not a useful tool for risk stratification prior to transport. MEWS was able to identify patients at risk but was not ideal.

Aeromedical agencies are used routinely to transport critically ill patients to specialty centers. The characteristics of patients suffering a cardiac arrest during transport by aeromedical flight personnel are not well-documented. We completed a retrospective analysis of aeromedical patient care records in order to describe the pre-arrest characteristics and the return of spontaneous circulation (ROSC) in this subset of patients. ⋯ Cardiac arrest during aeromedical transport is infrequent. Patients with poor i.v. access are less likely to experience ROSC should they experience a cardiac arrest. Patients with traumatic injury and diastolic hypotension may be less likely to survive cardiac arrest during transport.

Israel is a small country with a population of around 7 million. The sole EMS provider for Israel is Magen David Adom (MDA) (translated as 'Red Shield of David'). MDA also carries out the functions of a National Society (similar to the Red Cross) and provides all the blood and blood product services for the country. ⋯ Local geopolitics has meant that MDA has to be prepared for anything from everyday emergency calls to suicide bombings and regional wars. MDA also prides itself in being able to rapidly assemble and dispatch mobile aid teams to scenes of international disasters. Such a broad range of activities is unusual for a single EMS organisation.

Most survivors of out-of-hospital cardiac arrest (OHCA) will die subsequently from post-anoxic encephalopathy. In animals, the severity of brain damage is mainly influenced by the duration of cardiac arrest and also by the cerebral blood flow (CBF) and oxygen extraction (CEO2) abnormalities observed during the post-resuscitation period. The aim of our study was to describe CBF and CEO2 modifications during the first 72 h in OHCA patients treated by induced mild hypothermia. ⋯ Cerebral haemodynamic and oxygenation values are altered considerably but evolve during the first 72 h following resuscitation after cardiac arrest. In particular, these changes may lead to a mismatch between CBF and CEO2 leading to a "luxurous perfusion" in non-survivors.
