Multicenter StudyThe role of computed tomographic scan in ongoing triage of operative hepatic trauma: A Western Trauma Association multicenter retrospective study.
A subset of patients explored for abdominal injury have persistent hepatic bleeding on postoperative computed tomography (CT) and/or angiography, either not identified or not manageable at initial laparotomy. To identify patients at risk for ongoing hemorrhage and guide triage to angiography, we investigated the relationship of early postoperative CT scan with outcomes in operative hepatic trauma. ⋯ Care management/therapeutic study, level IV; epidemiologic/prognostic study, level III.

Comparative StudyGeriatric trauma G-60 falls with hip fractures: A pilot study of acute pain management using femoral nerve fascia iliac blocks.
Hip fractures due to falls cause significant morbidity and mortality among geriatric patients. A significant unmet need is an optimal pain management strategy. Consequently, patients are treated with standard analgesic care (SAC) regimens, which deliver high narcotic doses. However, narcotics are associated with delirium as well as gastrointestinal and respiratory failure risks. The purpose of this pilot study was to determine the safety and effectiveness of ultrasound-guided continuous compartmental fascia iliaca block (CFIB) in patients 60 years or older with hip fractures in comparison with SAC alone. ⋯ Therapeutic study, level IV.

Comparative StudyCadaveric comparison of the optimal site for needle decompression of tension pneumothorax by prehospital care providers.
Computed tomographic and cadaveric studies have demonstrated needle decompression of tension pneumothorax at the fifth intercostal space (ICS), anterior axillary line (AAL) has advantages over the second ICS midclavicular line (MCL). The purpose of this study was to compare the ability of prehospital care providers to accurately decompress the chest at these two locations. ⋯ For prehospital care providers, the fifth ICS AAL can be localized and decompressed with a higher degree of accuracy than the traditional second ICS MCL. It is rated as easier to perform and can be done just as quickly. Based on these data, the fifth ICS AAL should be considered as an equivalent first-line position for needle decompression in patients with clinical evidence of a tension pneumothorax.

Comparative StudyResuscitative endovascular balloon occlusion of the aorta (REBOA): Comparison with immediate transfusion following massive hemorrhage in swine.
Resuscitative endovascular balloon occlusion of the aorta (REBOA) is less invasive than emergency department thoracotomy for the treatment of massive hemorrhage. We evaluated the effects of REBOA on carotid blood flow (Qcarotid) in a porcine model of massive hemorrhage. We hypothesized that REBOA restores Qcarotid faster than reinfusion of blood. ⋯ REBOA resulted in the restoration of Qcarotid ("cerebrovascular resuscitation") at least as rapidly as retransfusion of shed blood, with equivalent 4-hour survival. Further studies of REBOA, to include mitigation of end-organ effects and longer follow-up, are needed.

Shock-induced systemic hyperfibrinolysis is attenuated by plasma-first resuscitation.
We developed a hemorrhagic shock animal model to replicate an urban prehospital setting where resuscitation fluids are limited to assess the effect of saline versus plasma in coagulopathic patients. An in vitro model of whole blood dilution with saline exacerbated tissue plasminogen activator (tPA)-mediated fibrinolysis, while plasma dilution did not change fibrinolysis. We hypothesize that shock-induced hyperfibrinolysis can be attenuated by resuscitation with plasma while exacerbated by saline. ⋯ Systemic hyperfibrinolysis is driven by hypoperfusion and associated with increased levels of tPA. Plasma is a superior resuscitation fluid to NS in a prehospital model of severe hemorrhagic shock as it attenuates hyperfibrinolysis and improves systemic perfusion.
