Permissive hypotension in bleeding trauma patients: helpful or not and when?
Severity of hemorrhage and rate of bleeding are fundamental factors in the outcomes of trauma. Intravenous administration of fluid is the basic treatment to maintain blood pressure until bleeding is controlled. The main guideline, used almost worldwide, Advanced Trauma Life Support, established by the American College of Surgeons in 1976, calls for aggressive administration of intravenous fluids, primarily crystalloid solutions. ⋯ With permissive hypotension, also known as hypotensive resuscitation, fluid administration is less aggressive. The available models of permissive hypotension are based on hypotheses in hypovolemic physiology and restricted clinical trials in animals. Before these models can be used in patients, randomized, controlled clinical trials are necessary.

Comparative Study
Hypercoagulability following blunt solid abdominal organ injury: when to initiate anticoagulation.
The optimal time to initiate venous thromboembolism pharmacoprophylaxis after blunt abdominal solid organ injury is unknown. ⋯ Patients sustaining blunt abdominal solid organ injuries transition to a hypercoagulable state approximately 48 hours after injury. In the absence of contraindications, pharmacoprophylaxis should be considered before this time for effective venous thromboembolism prevention.

ReviewSalvage techniques in traumatic cardiac arrest: thoracotomy, extracorporeal life support, and therapeutic hypothermia.
Survival from traumatic cardiac arrest is associated with a very high mortality despite aggressive resuscitation including an Emergency Department thoracotomy (EDT). Novel salvage techniques are needed to improve these outcomes. ⋯ Salvage techniques, such as earlier thoracotomy, ECLS, and hypothermia, may allow survival from otherwise lethal injuries.

ReviewMilitary trauma system in Afghanistan: lessons for civil systems?
This review focuses on development and maturation of the tactical evacuation and en route care capabilities of the military trauma system in Afghanistan and discusses hard-learned lessons that may have enduring relevance to civilian trauma systems. ⋯ Transfer of the lessons learned in the military trauma system operating in Afghanistan to civilian trauma systems with a comparable burden of prolonged evacuation times may be realized in improved patient outcomes in these systems.

Although early acute traumatic coagulopathy has received much recent attention, the procoagulopathy that often follows appears less appreciated. Thromboembolic disease following trauma is common and lethal, but very effective prophylactic strategies are available. These strategies are variably implemented because of the difficulty in quantifying the magnitude of procoagulopathy in individual patients. ⋯ The logical next step following from the improved pathophysiological understanding of the procoagulopathy of trauma should be a simultaneous clinical trial of procoagulopathy diagnosis and thromboembolic prophylaxis.
