Technological advances over the past two decades have paved the way for the prehospital use of ultrasound. This practice was first developed in traumatology and then in a multitude of other indications, including cardiology. The development of pulmonary ultrasound is certainly the most visible illustration of this. Firstly, because it is an extra-cardiac examination that provides the answer to a cardiac question. Secondly because from a theoretical point of view this ultrasound indication was a bad indication for the use of ultrasound due to the air contained in the thorax. Thirdly, because this indication has become a 'standard of care' when caring for a patient with dyspnea - a practice that has become widespread during the COVID epidemic. In patients with heart failure, ultrasound has a high diagnostic power (including for alternative diagnoses) which is all the more precise since the technique is non-invasive, the response is obtained quickly, the examination can be repeated at desire to follow the evolution of the patient. The main other indications for prehospital ultrasound are cardiac arrest to search for a curable cause, identification of residual mechanical cardiac activity, monitoring of cerebral perfusion; chest pain, for both positive and negative diagnoses; shock for the search for an etiology and therapeutic follow-up or even pulmonary embolism or ultrasound for the search for dilation of the right ventricle which is now at the forefront of the recommendation algorithm., (Copyright © 2022.

Echo contrast agents, such as SonoVue ® , (Bracco, Milan, Italy) are often used to enhance diagnosis. Although their use is safe, some rare side effects could be severe or even fatal. We are reporting a case of severe systemic allergic reaction after infusion of SonoVue ® . After a brief review of the literature, the aim of this paper is to draw attention to this risk and recall the safety instructions coming with the use of ultrasound contrast agents., (Copyright © 2017 Elsevier Masson SAS.

Shock after protamine infusion are rare. We report here the case of a 6-day-old boy having presented severe and recurring hypotensions after protamine infusions during cardiac surgery under cardio pulmonary bypass. The physiopathology of these reactions is complex and, in the presented case, involved mechanism may not be anaphylactic., (Copyright © 2013 Société française d’anesthésie et de réanimation (Sfar).

Objective: This review aims at providing an update on post-cardiac arrest syndrome, from pathophysiology to treatment., Data Sources: Medline database., Data Extraction: All data on pathophysiology, clinical manifestations and therapeutic management, with focus on the publications of the 5 last years., Data Synthesis: Care of the patients after cardiac arrest is a medical challenge, in face of "post-cardiac arrest syndrome", which culminates into multi-organ failure. This syndrome mimics sepsis-related dysfunctions, with all clinical and biological manifestations related to the phenomenon of global ischemia-reperfusion. Acute cardiocirculatory dysfunction is usually controlled through pharmacological and mechanical support. Meanwhile, as a majority of cardiac arrest is related to myocardial infarction, early angiographic exploration should then be discussed when there is no obvious extracardiac cause, percutaneous coronary revascularization being associated with improved short and long-term prognosis. Therapeutic hypothermia is the cornerstone of neuroprotective armamentarium, beyond hemodynamic stabilization and metabolic maintenance., Conclusion: If ongoing evaluations should shed light on potential efficiency of new therapeutic drugs, a multidisciplinary approach of the post-cardiac arrest syndrome in expertise centre is essential., (Copyright © 2013 Société française d’anesthésie et de réanimation (Sfar).
