Resuscitation

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.

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.

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.

Mild hypothermia (32-35 degrees C) impairs primary haemostasis and coagulation. Correction of these haemostatic impairments by rewarming alone may not be possible or desirable, particularly in major trauma, neuroanaesthesia and in critically ill patients. Pharmacological treatment of these impairments, if available, may be a useful alternative. Desmopressin has been used to treat various congenital and acquired platelet disorders, but its effects on hypothermia-induced impairment of primary haemostasis is not known. This study aims to investigate the in vitro effects of desmopressin on hypothermia-induced impairment of primary haemostasis using PFA-100 platelet function analyzer. ⋯ Desmopressin partially reverses hypothermia-induced impairment of primary haemostasis in vitro, and may be potentially useful in improving haemostasis in hypothermic patients with bleeding where immediate rewarming is difficult or undesirable.

The emergence of prothrombotic agents (e.g. activated factor VII) to treat traumatic brain injury (TBI) requires a better understanding of the association of coagulopathy with isolated head injury (IHI). ⋯ Coagulopathy as defined by elevated INR and/or PTT is associated with TBI after isolated head injury.
