["Highlights" in emergency medicine -- severe head trauma, polytrauma and cardiac arrest].

According to scientific publications focusing on emergency medicine and published in international journals in the past few months, new and clinically important results can be identified. In patients with severe head trauma (SHT), application of hypertonic solutions is possible; long term outcome, however, is not improved by this measure. Prehospital capnometry is important, because otherwise up to 40 % of all mechanically ventilated patients are hypoventilated.

[Emergency medicine -- new concepts and therapies improve outcome from cardiac arrest].

According to scientific articles focusing on emergency medicine published in international journals in the past few months, early defibrillation by lay persons, thrombolysis during cardiopulmonary resuscitation (CPR) and treatment with mild therapeutic hypothermia have been identified as relevant, new and clinically important treatment options to improve outcome following cardiac arrest. Early defibrillation using automated external defibrillators by lay persons reduces the time interval between collapse and first attempts at defibrillation and thus improves outcome after prehospital cardiac arrest. Thrombolysis during CPR -- for which the results regarding safety and efficacy are available from nonrandomized trials -- can also be safely performed in case of pulseless electrical activity.
