Traumatic hemorrhage and chain of survival.

Trauma is the number one cause of death among Americans between the ages of 1 and 46 years, costing more than $670 billion a year. Following death related to central nervous system injury, hemorrhage accounts for the majority of remaining traumatic fatalities. Among those with severe trauma that reach the hospital alive, many may survive if the hemorrhage and traumatic injuries are diagnosed and adequately treated in a timely fashion. This article aims to review the recent advances in pathophysiology management following a traumatic hemorrhage as well as the role of diagnostic imaging in identifying the source of hemorrhage. The principles of damage control resuscitation and damage control surgery are also discussed. The chain of survival for severe hemorrhage begins with primary prevention; however, once trauma has occurred, prehospital interventions and hospital care with early injury recognition, resuscitation, definitive hemostasis, and achieving endpoints of resuscitation become paramount. An algorithm is proposed for achieving these goals in a timely fashion as the median time from onset of hemorrhagic shock and death is 2 h.

Echocardiography and Management for Cardiac Trauma.

Trauma is the number one cause of death among Americans between the ages of 1 and 46, costing >$670 billion a year. Blunt and penetrating trauma can lead to cardiac and aortic injuries, with the incidence of death varying upon the location of the damage. Among those who reach the hospital alive, many may survive if the hemorrhage and cardiovascular injuries are diagnosed and treated adequately in a timely fashion. Although echocardiography often is underused in the setting of cardiac trauma, it offers significant diagnosis and treatment potential because it is accessible in most settings, safe, relatively noninvasive, and can provide rapid and accurate trauma assessment in the hands of trained providers. This review article aims to analyze the pathophysiology of cardiac injuries in patients with trauma and the role of echocardiography for the accurate diagnosis of cardiac injury in trauma. This review, additionally, will offer a patient-centered, team-based, early management plan with a treatment algorithm to help improve the quality of care among these patients with cardiac trauma.
