To test a high-frequency jet ventilator, the Mistral (Acutronic Laboratory) on a lung model. ⋯ The use of a low volume connector should be preferred, because it allows the measurement of the end expiratory pressure for a larger range of driving pressure, expiratory time and catheters. The performances of the Seldicath catheter are below those of the other catheters studied.

[Introduction of the intubating Laryngeal Mask Airway in a prehospital emergency medical unit].
Assessment of the intubating Laryngeal Mask Airway(trade mark) in a prehospital emergency mobile unit (PEMU). ⋯ The ILMA is a potential useful device in the prehospital setting. Initial formation and maintenance of the skill acquired with this technique are essential.

Randomized Controlled Trial[Prevention of myoclonus after etomidate using a priming dose].
To investigate the influence of pretreatment with a low dose of etomidate (priming dose) on the incidence of etomidate-induced myoclonus. ⋯ Pretreatment with etomidate (0.03 mg/kg), given 60 seconds before induction of anesthesia, is effective at reducing etomidate-induced myoclonus, without related side-effect.

The aims of this review are to precise the pathophysiological mechanisms leading to biguanide-associated lactic acidosis, to give elements of diagnosis, and to underline the precautionary conditions for prescribing these drugs by an improvement in physicians and patient's education. ⋯ Due to its beneficial effects, metformin is the gold standard treatment for overweight type 2 diabetic patients. The essential precautionary conditions for prescribing metformin as well as the respect of its contra-indications permit largely to prevent lactic acidosis. This complication is serious when it is associated with intercurrent illnesses and metformin accumulation. The curative treatment is based on renal replacement therapy. Prevention only rests on the respect of the contra-indications. Education of physicians and patients concerning the rules of prescription remains essential.

Review[The use of cardiac troponins (T or I) measurement in cardiology and various clinical settings].
Measurement of cardiac troponin I or T in serum (highly specific for the myocardium) have replaced classical markers, such as creatine kinase MB. Cardiac troponins are preferred markers because of their high specificity and sensitivity. This had led to modifications of the original World Health Organization criteria for acute myocardial infarction. ⋯ Increases of troponin indicate cardiac damage, whatever the mechanism (ischemic or not). Other causes of cardiac injury include: pulmonary embolism, myocarditis, pericarditis, congestive heart failure, septic shock, myocardial contusion. In most cases, elevation of troponins has been shown to be associated with a bad outcome.
