Despite higher rates of stabbing and shooting violence among black men, healthcare systems have not demonstrated an efficacious response to these patients. This study describes challenges and promotive factors for engaging black male violence victims of violence with medical and mental healthcare. ⋯ For black male violence victims, medical treatment did not address circumstances of and reactions to injury. Policies delineating boundaries between medical care and law enforcement and addressing postinjury mental health symptoms, disability, and safety concerns may improve the recovery process.

The purpose of this study was to examine the incidence of tissue hypoperfusion in victims of severe traumatic brain injury (sTBI) and to determine the associations between hypoperfusion and TBI coagulopathy. ⋯ Hypoperfusion is an independent risk factor for the development of early coagulopathy in patients with isolated sTBI. Nevertheless, early coagulopathy after sTBI does not occur exclusively in patients experiencing tissue hypoperfusion.

Ventilation of Acute Respiratory Distress Syndrome (ARDS) is a challenge, and there is definitely a need for lack of variations between delivered and set tidal volume (Vt). We have assessed the ability of the ventilator T-birdVS02 and LTV-1000 to deliver to a lung model with ARDS a set Vt at different simulated altitudes. ⋯ Clinicians involved in aerial evacuations must keep in mind the performance and limitations of their ventilator system.

Hemorrhage is a frequent cause of morbidity and mortality, possibly complicated by volatile anesthetics administered during surgical emergencies. Because methylene blue (MB) was suggested to reduce bleeding, we reasoned that it may improve resuscitation. We used a rat model of controlled and uncontrolled hemorrhage with fluid resuscitation, aiming at high versus low mean arterial pressure (MAP) to assess the role of early MB injection on survival and the effects of different anesthetics on outcome. ⋯ MB improved parameters and survival rates after controlled and uncontrolled hemorrhage and fluid resuscitation, even in high MAP-resuscitated rats. KET seemed to be the best anesthetic choice among the four classic agents tested. The effects of balanced anesthesia and total intravenous anesthesia in similar conditions require additional studies.
