Background The aim of this study is to compare impact of COVID-19 on trauma volume and characteristics on a set of trauma centers with a rural catchment area. The COVID-19 pandemic has affected different parts of the country quite differently, both in case volume and in local responses. State-wide responses have varied considerably, including variations in local mask mandates, school closures, and social distancing measures. Methods This was a retrospective trauma registry review of patients who were admitted to three of the tertiary care trauma centers in North and South Dakota between 2014 through 2022. Results In the analysis of 36,397 patients, we found a significant increase in trauma patient volume during the COVID-19 pandemic, with an increased percentage of patients presenting with a mechanism of injury secondary to abuse or assault. This increase in patient volume continued to rise during 2021 and 2022. Conclusions Our study demonstrates how the COVID-19 pandemic impacted trauma center admissions in the rural and frontier Midwest differently from more urban areas, and the importance of including a variety of settings in trauma research.

Introduction: Tension pneumothorax related to chest trauma is a rapidly lethal condition that requires immediate treatment, often prior to arrival at definitive care. Recent concerns regarding the safety and efficacy of needle thoracostomy (NT) have led to alternatives. Finger thoracostomy (FT) is a potential life-saving treatment performed by prehospital providers as an alternative to NT. We hypothesize that FT has improved rates of prehospital thoracic decompression and is a safe alternative to NT. Materials and Methods: Retrospective cohort study of consecutive adult trauma patients presenting to a Level 1 trauma center who sustained chest trauma. A matched cohort of patients who underwent prehospital FT was compared to patients who underwent prehospital NT for thoracic decompression. Wilcoxon Rank Sum Test and Chi-Squared Analyses were performed for comparison of prehospital and in-hospital outcome variables. Results: 34 patients were compared, of which 15 underwent prehospital FT and 19 underwent prehospital needle thoracostomy NT. Groups were well matched in terms of demographics and injury characteristics. No difference in transport times were observed. All 15 patients in the FT group sustained cardiac arrest prior to arrival with 20% achieving return of spontaneous circulation (ROSC), while 6/19 NT patients arrived in cardiac arrest, with 66.7% achieving ROSC (p = 0.04). The rate of successful intrathoracic decompression was higher in the FT group (93.3% vs 47.4%, p<0.001). The NT group had a higher rate of chest tube placement (p=0.005). In-hospital mortality was not different between the two groups (p=0.213). Conclusions: FT is a viable alternative to NT for emergent thoracic decompression. The higher success rate of intrathoracic decompression supports the use of FT as an alternative to NT for prehospital tension pneumothorax, although future studies are needed establish superiority and further evaluate mortality and in-hospital outcomes.

Background: Tension pneumothorax resulting from chest trauma is a rapidly fatal condition that requires prompt treatment. Prehospital open thoracostomy (POT) is a potentially lifesaving intervention that can be performed in the field to treat tension pneumothorax. However, the results from POT performed by ground EMS providers have not been well-studied. The objective of this study was to compare outcomes for patients with chest trauma who underwent POT performed by ground EMS providers with a matched cohort who did not undergo this procedure in the field. Methods: A retrospective chart review of consecutive adult patients presenting to a Level I trauma center with chest trauma were analyzed from 2017-2020. Outcomes were compared to a patient cohort who did not undergo POT matched by severity of injury and prehospital CPR. Results: A total of 14 POT patients were identified. Majority of POT were bilateral (n=11/14, 78.6%) and all of these patients (n=14/14) had prehospital cardiac arrest. Return of spontaneous circulation was obtained in 2 patients with penetrating injuries (14.3%). There was no difference in total and scene EMS time compared to the matched cohort without POT (p>0.05). Conclusions: This study demonstrated that open thoracostomies could be performed by ground EMS units without increasing prehospital time for severely injured trauma patients and greater achievement of ROSC. Larger, prospective, multi-institutional analyses are needed to further evaluate outcomes.

INTRODUCTION:One of the significant complications of operative liver trauma is intra-abdominal abscesses (IAA). The objective of this study was to determine risk factors associated with postoperative IAA in surgical patients with major operative liver trauma. METHODS:A retrospective multi-institutional study was performed at 13 Level 1 and Level 2 trauma centers from 2012 to 2021. Adult patients with major liver trauma (grade 3 and higher) requiring operative management were enrolled. Univariate and multivariate analyses were performed. RESULTS:Three hundred seventy-two patients were included with 21.2% (n = 79/372) developing an IAA. No difference was found for age, gender, injury severity score, liver injury grade, and liver resections in patients between the groups (P > 0.05). Penetrating mechanism of injury (odds ratio (OR) 3.42, 95% confidence interval (CI) 1.54-7.57, P = 0.02), intraoperative massive transfusion protocol (OR 2.43, 95% CI 1.23-4.79, P = 0.01), biloma/bile leak (OR 2.14, 95% CI 1.01-4.53, P = 0.04), hospital length of stay (OR 1.04, 95% CI 1.02-1.06, P < 0.001), and additional intra-abdominal injuries (OR 2.27, 95% CI 1.09-4.72, P = 0.03) were independent risk factors for IAA. Intra-abdominal drains, damage control laparotomy, total units of packed red blood cells, number of days with an open abdomen, total abdominal surgeries, and blood loss during surgery were not found to be associated with a higher risk of IAA. CONCLUSIONS:Patients with penetrating trauma, massive transfusion protocol activation, longer hospital length of stay, and injuries to other intra-abdominal organs were at higher risk for the development of an IAA following operative liver trauma. Results from this study could help to refine existing guidelines for managing complex operative traumatic liver injuries.

Whole blood (WB) transfusion for trauma patients with severe hemorrhage has demonstrated early successful outcomes compared to conventional component therapy. The objective of this study was to demonstrate WB transfusion in the non-trauma patient. Consecutive adult patients receiving WB transfusion at a single academic institution were reviewed from February 2018 to January 2020. Outcomes measured were mortality and transfusion-related reactions. A total of 237 patients who received WB were identified with 55 (23.2%) non-trauma patients. Eight patients (14.5%) received pre-hospital WB. The most common etiology of non-traumatic hemorrhage was gastrointestinal bleeding (43.6%, n = 24/55). Approximately half of the non-trauma patients (n = 28/55) received component therapy. Transfusion-related events occurred in 3 patients. This study demonstrated that non-trauma patients could receive WB transfusions safely with infrequent transfusion-related events. Future studies should focus on determining if outcomes are improved in non-trauma patients who receive WB transfusions and defining specific transfusion criteria for this population.

BACKGROUND:Low titer O+ whole blood (LTOWB) is being increasingly used for resuscitation of hemorrhagic shock in military and civilian settings. The objective of this study was to identify the impact of prehospital LTOWB on survival for patients in shock receiving prehospital LTOWB transfusion. STUDY DESIGN AND METHODS:A single institutional trauma registry was queried for patients undergoing prehospital transfusion between 2015 and 2019. Patients were stratified based on prehospital LTOWB transfusion (PHT) or no prehospital transfusion (NT). Outcomes measured included emergency department (ED), 6-h and hospital mortality, change in shock index (SI), and incidence of massive transfusion. Statistical analyses were performed. RESULTS:A total of 538 patients met inclusion criteria. Patients undergoing PHT had worse shock physiology (median SI 1.25 vs. 0.95, p < .001) with greater reversal of shock upon arrival (-0.28 vs. -0.002, p < .001). In a propensity-matched group of 214 patients with prehospital shock, 58 patients underwent PHT and 156 did not. Demographics were similar between the groups. Mean improvement in SI between scene and ED was greatest for patients in the PHT group with a lower trauma bay mortality (0% vs. 7%, p = .04). No survival benefit for patients in prehospital cardiac arrest receiving LTOWB was found (p > .05). DISCUSSION:This study demonstrated that trauma patients who received prehospital LTOWB transfusion had a greater improvement in SI and a reduction in early mortality. Patient with prehospital cardiac arrest did not have an improvement in survival. These findings support LTOWB use in the prehospital setting. Further multi-institutional prospective studies are needed.

Hemorrhagic shock remains the leading cause of preventable death on the battlefield, despite major advances in trauma care. Early initiation of balanced resuscitation has been shown to decrease mortality in the hemorrhaging patient. To address transfusion limitations in austere environments or in the event of multiple casualties, walking blood banks have been used in the combat setting with great success. Leveraging the success of the region-wide whole blood program in San Antonio, Texas, we report a novel plan that represents a model response to mass casualty incidents.
