Case Reports[Sudden death caused by a less lethal weapon chest-wall injury (Commotio cordis)].
Less lethal weapons, like Flashball, are more and more used since 1995 in law enforcement, even by the local police to neutralize combative individuals and to disperse riot crowds. This gun fires large rubber bullets and has been incriminated many times in cases of face injuries with functional consequences. ⋯ Commotio cordis is potentialized by a lethal set of three including, a certain impact velocity, an exact location of the hit over the cardiac silhouette, and a precise timing 15 m/s prior to the peak of the T-wave. This case report highlights the fact that such impacts can cause significant injury to internal organs, in particular circonstances, implying the necessity of a raising awareness of the medical staff, in ordre to not underestimate the severity of such injuries.

[Vasoreactivity changes during extracorporeal circulation: effects of halogenated agents].
During cardiopulmonary bypass (CPB), endothelium is exposed to multiple disturbances leading to significant vasomotor tone and vascular systemic resistances (VSR) level modifications. Properties of endothelial function on vascular tone were summarized herein. According bibliographic findings, physiological and clinical impacts of respectively halogenated agents and CPB concerning vasomotor tone were reported. ⋯ Incidence of severe vasoplegia was established to 9.5 % in the studied population and this result was similar as others. More over predicting factors of severe vasoplegia were the same as previously reported : severity of preoperative clinical status according Euroscore, hemodynamical instability before induction of anesthesia, surgical procedure complexity and CPB duration. Absence of deleterious effects in SVR decrease when administering isoflurane during normothermic CPB was assumed but prospective comparative studies comparing effects of halogenated agents and other anesthetic agents are needed in order to confirm these findings.

Initially double-lung transplantation (DLT) was performed with airway anastomosis at the tracheal bifurcation requiring a cardiopulmonary bypass (CBP). Complications related to ischemia of the bronchi and trachea around the carina prompted adoption of sequential single lung implantations as the method of choice for DLT. ⋯ Therefore, the systematic use of CPB during sequential lung transplantation might have some interest by limiting the occurrence of ventilation and perfusion injuries. This article discusses the potential beneficial effects of CPB during double-lung transplantation.
