Randomized Controlled Trial
Does the type of out-of-hospital airway interfere with other cardiopulmonary resuscitation tasks?
Out-of-hospital rescuers often perform tracheal intubation (TI) prior to other cardiopulmonary resuscitation (CPR) interventions. TI is a complex and error-prone procedure that may interfere with other key resuscitation tasks. We compared the effects of TI versus esophageal tracheal combitube (ETC) insertion on the accomplishment of other interventions during simulated cardiopulmonary resuscitation. ⋯ Compared with TI, ETC reduced time to airway placement and time without chest compressions, but did not affect elapsed times to accomplish other interventions. Additional time differences may be realized if translated to clinical out-of-hospital conditions.

Our objectives were to determine the most effective, safe, and feasible first aid (FA) techniques and procedures, and to formulate valid recommendations for training. We focussed on emergencies involving few casualties, where emergency medical services or healthcare professionals are not immediately present at the scene, but are available within a short space of time. Due to time and resource constraints, we limited ourselves to safety, emergency removal, psychosocial FA, traumatology, and poisoning. Cardiopulmonary resuscitation (CPR) was not included because guidelines are already available from the European Resuscitation Council (ERC). The FA guidelines are intended to provide guidance to authors of FA handbooks and those responsible for FA programmes. These guidelines, together with the ERC resuscitation guidelines, will be integrated into a European FA Reference Guide and a European FA Manual. ⋯ Where good evidence was available, we were able to turn science into practice. Where evidence was lacking, the recommendations were consensus-based. These guidelines provide systematically developed recommendations and justifications for the procedures and techniques that should be included in FA manuals and training programmes.

Case Reports
Amniotic fluid embolism after surgical trauma: two case reports and review of the literature.
Amniotic fluid embolism (AFE) is a relatively rare condition usually occurring during or shortly after pregnancy and is catastrophic in most cases. The classical description is a sudden onset of dyspnoea, cyanosis and hypotension out of proportion to the blood loss, followed quickly by cardiorespiratory arrest. ⋯ We report on two cases of severe and near fatal amniotic fluid embolism during pregnancy. Surgical trauma, caused by a blow in the stomach and a surgical intervention, was considered to be the aetiology.

The response to exchange transfusion with red blood cells (RBCs) saturated with carbon monoxide (CO) in amelioration of microvascular function and providing tissue protection in hemorrhagic shock resuscitation was investigated in the hamster chamber window model. Shock was induced by the withdrawal of 50% of blood volume (BV). Blood volume was restored 1 h after hemorrhage with a single volume infusion (resuscitation) of 25% BV with fresh RBCs (saturated or unsaturated with CO) suspended in human serum albumin (HSA). ⋯ CO saturated blood partially mitigated cell injury at 8 h after resuscitation. The precise cellular mechanisms involved require further elucidation. CO is a novel experimental strategy to improve tissue viability and requires the appropriated preclinical studies to confirm its efficacy.

Less than 1% of the general public know how to assess or manage someone who has collapsed. It has been estimated that if 15-20% of the population were capable of performing cardiopulmonary resuscitation (CPR), mortality of out of hospital cardiac arrest could be decreased significantly. Training basic life support (BLS) skills to school children would be the most cost effective way of achieving this goal and ensuring that a large proportion of the population acquire basic life saving skills. ⋯ A training programme designed and taught as part of the school curriculum would have a significant impact on public health.
