Indications à la coronarographie en urgence. Partie II: syndromes coronariens aigus sans élévation du segment ST [Indications for urgent coronary angiography. Part II: Acute coronary syndromes without ST-segment elevation]

The optimal treatment strategy for patients presenting with an acute coronary syndrome without ST elevation is controversial and different therapeutic approaches are recognized. Currently, given the literature available, it is not possible to recommend a universal systematic invasive approach. It is essential to individually risk stratify patients in order to identify those high risk patients that have been shown to benefit from an invasive strategy. Compared to conservative medical treatment, patients at low risk have not been shown to benefit from an invasive strategy. Urgent coronary angiography remains recommended for those patients with persistent or recurrent ischemic symptoms under optimal medical treatment.

Prise en charge des coliques néphrétiques en urgence [Emergency management of renal colic]

Renal colic (RC) is a common problem in primary care practice. It is estimated that 5-12% of the general population will suffer once RC during his lifetime. The primary care physicians play a central role in the management of urolithiasis. This article summarizes the current recommendations in terms of renal colic emergency management: biological assessment, imaging, pain relief and specific treatment. The vast majority of patients only needs efficient antalgic treatment and an outpatient monitoring. A minimal assessment must however be undertaken to detect complicated RC that will require urgent treatment in urology department. The analysis of the stone after the crisis is crucial to set up a preventive treatment.

Apprendre dans l'urgence

Nous avons effectué une étude dans le but d'investiger les stratégies utilisées par les ambulanciers pour préserver leur santé. Parmi les stratégies que nous avons identifiées, celles contribuant au maintien et au développement des compétences nous ont semblé particulièrement intéressantes car elles permettent de réduire le stress lié à la peur de l'erreur. Elles permettent aussi aux ambulanciers "d'apprivoiser l'urgence" en leur donnant la possibilité de jouer un rôle actif face aux difficultés rencontrées. Nous présentons quelques-unes de ces stratégies dans cet article.

Traumatologie de la personne âgée : une urgence nutritionnelle ? [Elderly orthopedic patients: Is nutritional support needed?]

La fracture de hanche chez la personne âgée reste un problème de santé publique. Elle est la conséquence d'une chute neuf fois sur dix et survient chez des personnes fragilisées par une ostéoporose, une sarcopénie, une dénutrition. Dans un service de traumatologie, la dénutrition protéino-énergétique est fréquente. Présente dès l'admission chez environ un patient sur deux, elle va souvent s'aggraver pendant le séjour hospitalier et favoriser la survenue de complications. Une prise en charge nutritionnelle doit impliquer une équipe multidisciplinaire qu'il faut coordonner. Elle doit être envisagée précocement pendant le séjour hospitalier et privilégier la voie orale. L'assistance nutritionnelle sous forme de CNO a prouvé son efficacité dans la réduction de la morbidité postopératoire. Son impact sur la mortalité, sur le pronostic fonctionnel et social reste discuté. Il faudra attendre l'étude de nouvelles cohortes dans lesquelles la compliance au traitement est nettement améliorée avant de conclure de manière définitive.

Médecine d'urgence [Emergency medicine: updates 2013].

New evidences published this year are susceptible to change the management of several medical emergencies. Combined antiplatelet therapy might be beneficial for the management of TIA or minor stroke and rapid blood pressure lowering might improve the outcome in patients with intracerebral hemorrhage. A restrictive red cell transfusion strategy is indicated in case of upper digestive bleeding and coagulation factors concentrates are superior to fresh frozen plasma for urgent warfarin reversal. Prolonged systemic steroid therapy is not warranted in case of acute exacerbation of BPCO, and iterative physiotherapy is not beneficial after acute whiplash. Finally, family presence during cardiopulmonary resuscitation may reduce post-traumatic stress disorder among relatives.

Médecine d'urgence [Emergency medicine: updates 2012].

We review some of the most influential papers from 2012 in the different aspects of emergency medicine, such as prehospital medicine, resuscitation, early diagnosis and timely ED discharge and treatment. In particular, intramuscular benzodiazepines have been shown to be efficient in prehospital status epilepticus, epinephrines usefulness in cardiopulmonary resuscitation has been challenged, colloids have been shown to be deleterious in the treatment of severe sepsis and septic shock, the time window for thrombolysis in acute stroke will probably be extended, acute pyelonephritis treatment duration can be decreased, new D-dimers thresholds for older patients may prevent further diagnosis tests, and hs-Troponin may allow earlier discharge of low coronary risk patients.

Indications à la coronarographie en urgence. Partie I: syndromes coronariens aigus avec élévation du segment ST [Indications for urgent coronary angiography. Part I: ST-segment elevation acute coronary syndromes]

The indications for urgent coronary angiography are stated in the guidelines for treatment of acute coronary syndromes. An invasive approach is considered the treatment of choice for patients presenting with ST elevation myocardial infarction within 12 hours of the beginning of symptoms. In the absence of contraindication, intravenous thrombolysis continues to be a valuable alternative to primary angioplasty within 3 hours of the beginning of clinical symptoms. Urgent coronary angiography continues to be recommended following the failure of thrombolysis, persistent myocardial ischemia after 12 hours of symptoms, recurrent myocardial ischemia following myocardial infarction or in the case of cardiogenic shock.
