Prehospital tourniquet use is now standard in trauma patients with diagnosed or suspected extremity vascular injuries. Tourniquet-related vasospasm is an understudied phenomenon that may confound management by causing erroneous arterial pressure indices (APIs) and abnormalities on computed tomography angiography (CTA) that do not reflect true arterial injuries. We hypothesized that shorter intervals between tourniquet removal and CTA imaging and longer total tourniquet times would be correlated with a higher likelihood of false positive CTA. ⋯ Arterial vasospasm is a frequent finding on CTA after tourniquet use for extremity trauma, but concerns regarding tourniquet-related vasospasm should not alter trauma patient management. Neither the duration of tourniquet application nor the time interval since removal is associated with decreased CTA accuracy, and any delay in imaging does not appear to reduce the likelihood of vasospasm. These findings are important for supporting expedited care of trauma patients with severe extremity injuries.

Truncal and junctional hemorrhage is the leading cause of potentially preventable deaths in trauma patients. To reduce this mortality, the application of advanced bleeding control techniques, such as resuscitative endovascular balloon occlusion of the aorta (REBOA), junctional tourniquets, Foley catheters, or hemostatic agents should be optimized. This study aimed to identify trauma patients with non-compressible truncal and junctional hemorrhage (NCTJH) who might benefit from advanced bleeding control techniques during initial trauma care. We hypothesized that there is a substantial cohort of Dutch trauma patients that can possibly benefit from advanced bleeding control techniques. ⋯ More than half of included Dutch trauma patients with NCTJH may benefit from in-hospital application of advanced bleeding control techniques, such as REBOA, during initial trauma care. Widespread implementation of these techniques in the Dutch trauma system may contribute to reduction of mortality and morbidity from non-compressible truncal and junctional hemorrhage.

The management of thoracoabdominal (TA) gunshot wounds (GSW) remains challenging. This study reviewed our experience with treating such injuries over a decade. ⋯ Thoraco-abdominal GSWs remain challenging to manage and continue to be associated with significant morbidity and mortality. The increased use of CT scans has reduced the degree of clinical confusion around which body cavity to prioritize, leading to an apparent decrease in dual cavity exploration, and has allowed for the increased use of minimalistic and non-operative approaches.

Traumatic Thoracic Aortic Injury (TTAI) is associated with high mortality rates and is the second leading cause of death in traumatic patients. There has been a considerable advancement in the management of TTAI with novel and improved surgical procedures and imaging modalities. The aim of this study was to determine the national demographic and regional trends in mortality associated with TTAI in the United States across twenty years, 1999 to 2019. ⋯ There was a significant decrease in the TTAI associated mortality trends in the United States across 1999-2019 with a consistent decline in all demographic and regional subgroups.

Observational Study
The nature and timing of coagulation dysfunction in a cohort of trauma patients in the Australian pre-hospital setting.
Acute Traumatic Coagulopathy (ATC) is a complex pathological process that is associated with patient mortality and increased blood transfusion requirements. It is evident on hospital arrival, but there is a paucity of information about the nature of ATC and the characteristics of patients that develop ATC in the pre-hospital setting. The objective of this study was to describe the nature and timing of coagulation dysfunction in a cohort of injured patients and to report on patient and pre-hospital factors associated with the development of ATC in the field. ⋯ Clinically significant, multifaceted coagulopathy develops early in the clinical course, with hypofibrinogenemia being the predominant coagulopathy. In keeping with the ED literature, pre-hospital coagulation dysfunction was associated with mortality and early massive transfusion. Further work is required to identify strategies to identify and guide the pre-hospital management of the coagulation dysfunction seen in trauma.
