Diagnosis of postoperative myocardial infarction is often difficult, based on tools with a low sensitivity (clinical symptoms, EKG), or with a low specifity (old biomarkers, echocardiographic abnormalities) or inadequate for clinical practice (scintigraphy). Since 1995, clinicians may use more cardiospecific markers (troponin) allowing to modify strategy for postoperative myocardial infarction diagnosis. The aim of this review is to resume such an attitude.

Fever is a secondary brain injury and may worsen neurological prognosis of neurological intensive care unit (NICU) patients. In response to an immunological threat, fever associates various physiological reactions, including hyperthermia. Its definition may vary but the most commonly used threshold is 37.5 degrees C. ⋯ Whereas no causal link has been established between fever and unfavourable outcome, it seems reasonable to treat hyperthermia in patients suffering from brain injuries. In such patients, antipyretics have a moderate efficacy. In case of failure, they should be replaced by physical cooling techniques.

[Results of a national survey about the use of sedation scales in emergency prehospital medicine].
The primary goal of sedation in emergency prehospital care is to guarantee the security of the mechanically ventilated patients by optimising their adaptation to the respirator. If the French prehospital guidelines are well codified, their applicability in routine clinical practice seem to be rather empirical. The aim of this national survey was to evaluate the use of the clinical sedation scales by the prehospital physicians. ⋯ The principal reasons given by the physicians for not using the sedation scales were their ignorance in 57% of the cases (n=200) and the systematic choice of a deep sedation in 42% of the cases (n=147). For 18% of them (n=62), the use of sedation scores was considered too complicated. The final results show that the utilisation ratio of the sedation scores is very low in emergency prehospital medicine and suggest that an effort toward improving the use of sedation in prehospital emergency medicine is necessary.
