RESUMEN
Importance: The spleen is often removed in laparotomy after traumatic abdominal injury, with little effort made to preserve the spleen. Objective: To explore the association of surgical management (splenic repair vs splenectomy) with outcomes in patients with traumatic splenic injuries undergoing laparotomy and to determine whether splenic repair is associated with lower mortality compared with splenectomy. Design, Setting, and Participants: This is a trauma registry-based cohort study using the American College of Surgeons Trauma Quality Improvement Program database from January 2013 to December 2019. Participants included adult patients with severe splenic injuries (Abbreviated Injury Scale [AIS] grades 3-5) undergoing laparotomy after traumatic injury within 6 hours of admission. Data analysis was performed from April to August 2023. Exposures: Splenic repair vs splenectomy in patients with severe traumatic splenic injury. Main Outcomes and Measures: The primary outcome was in-hospital mortality. Outcomes were compared using different statistical approaches, including 1:1 exact matching with consecutive conditional logistic regression analysis as the primary analysis and multivariable logistic regression, propensity score matching, and inverse-probability weighting as sensitivity analyses. Results: A total of 11â¯247 patients (median [IQR] age, 35 [24-52] years; 8179 men [72.7%]) with a severe traumatic splenic injury undergoing laparotomy were identified. Of these, 10â¯820 patients (96.2%) underwent splenectomy, and 427 (3.8%) underwent splenic repair. Among patients who underwent an initial splenic salvage procedure, 23 (5.3%) required a splenectomy during the subsequent hospital stay; 400 patients with splenic preservation were matched with 400 patients who underwent splenectomy (matched for age, sex, hypotension, trauma mechanism, AIS spleen grade, and AIS groups [0-2, 3, and 4-5] for head, face, neck, thorax, spine, and lower and upper extremity). Mortality was significantly lower in the splenic repair group vs the splenectomy group (26 patients [6.5%] vs 51 patients [12.8%]). The association of splenic repair with lower mortality was subsequently verified by conditional regression analysis (adjusted odds ratio, 0.4; 95% CI, 0.2-0.9; P = .03). Multivariable logistic regression, propensity score matching, and inverse-probability weighting confirmed this association. Conclusions and Relevance: In this retrospective cohort study, splenic repair was independently associated with lower mortality compared with splenectomy during laparotomy after traumatic splenic injury. These findings suggest that efforts to preserve the spleen might be indicated in selected cases of severe splenic injuries.

INTRODUCTION: Preperitoneal pelvic packing (PPP) has been advocated as a damage control procedure for pelvic fracture bleeding, despite of weak evidence. METHODS: Matched cohort study, TQIP database. Patients with isolated severe blunt pelvic fractures (pelvis abbreviated injury score [AIS] â≥ â3, AIS ≤2 in all other body regions) were included. Patients who underwent PPP were matched to patients with no PPP, 1:3 nearest propensity score. Matching was performed based on demographics, vital signs on admission, comorbidities, injury characteristics, type and timing of initiation of VTE prophylaxis, and additional procedures including laparotomy, REBOA, and angioembolization. RESULTS: 64 patients with PPP were matched with 182 patients with No-PPP. PPP patients had higher in-hospital mortality (14.1 â% vs 2.2 â% p â< â0.001) and higher rates of VTE and DVT (VTE: 14.1 â% vs 4.4 â% p â= â0.018, DVT: 10.9 â% vs 2.2 â% p â= â0.008). CONCLUSION: PPP is associated with worse survival outcomes and increased rate of VTE and DVT complications.
RESUMEN
BACKGROUND: Experimental work suggested that resuscitative Endovascular Balloon Occlusion of the aorta (REBOA) preserves cerebral circulation in animal models of traumatic brain injury. No clinical work has evaluated the role of REBOA in the presence of associated severe traumatic brain injury (TBI). We investigated the impacts of REBOA on neurological and survival outcomes. METHODS: Propensity-score matched study, using the American College of Surgeons Trauma Quality Improvement Program database. Patients with severe TBI patients (Abbreviated Injury Scale ≥3) receiving REBOA within 4 âh from arrival were matched with similar patients not receiving REBOA. Neurological matching included head AIS, pupils, and midline shift. Clinical outcomes were compared between the two groups. RESULTS: 434 REBOA patients were matched with 859 patients without REBOA. Patients in the REBOA group had higher rates of in-hospital mortality (63.6 â% vs 44.2 â%, p â< â0.001), severe sepsis (4.4 â% vs 2.2 â%, p â= â0.029), acute kidney injury (10.1 â% vs 6.6 â%, p â= â0.029), and withdrawal of life support (25.4 â% vs 19.6 â%, p â= â0.020) despite of lower craniectomy/craniotomy rate (7.1 â% vs 12.7 â%, p â< â0.002). CONCLUSION: In patients with severe TBI, REBOA use is associated with an increased risk of in-hospital mortality, AKI, and infectious complications.
RESUMEN
PURPOSE: Fat embolism syndrome (FES) is a serious complication after orthopedic trauma. The aim of this study was to identify risk factors for FES in isolated lower extremity long bone fractures. METHODS: The National Trauma Data Bank "NTDB" study included patients with isolated femoral and tibial fractures. A total of 344 patients with FES were propensity score matched with 981 patients without FES. Multivariate logistical regression was used to identify independent risk factors for FES. RESULTS: FES was diagnosed in 344 (0.03%) out of the 1,251,143 patients in the study populations. In the two matched groups, the mortality was 7% in the FES group and 1% in the No FES group (p < 0.001). FES was associated with an increased risk of ARDS, VTE, pneumonia, AKI, and stroke. Younger age, femur fractures, obesity, and diabetes mellitus were independent predictors of FES. Early operative fixation (≤ 48 h) was protective against FES. CONCLUSION: FES increases mortality by seven times. Young age, obesity, and diabetes mellitus are significant independent risk factors for FES. Early fixation is independently associated with a reduced risk of FES. LEVEL OF EVIDENCE: Level III. STUDY TYPE: Prognostic study.
RESUMEN
PURPOSE: Low-molecular-weight-heparin (LMWH) has been shown to be associated with a decreased risk of venous thromboembolism (VTE) and mortality compared to unfractionated heparin (UH) in severe traumatic brain injury (TBI). The aim of this study was to see if this association persists among a subset of patients, namely elderly patients with isolated TBI. METHODS: This Trauma Quality Improvement Project (TQIP) database study included patients ≥ 65 years old with severe TBI (Abbreviated injury score [AIS] ≥ 3) that received either LMWH or UH for VTE prophylaxis. Patients with associated severe injuries (extracranial AIS ≥ 3), transferals, deaths < 72-h, hospitalization < 2 days, VTE chemoprophylaxis other than UH or LMWH, or with a history of bleeding diathesis were excluded. The association between VTE, deep vein thrombosis (DVT), and pulmonary embolism (PE) with VTE chemoprophylaxis was analyzed with multivariable analysis, subset analyses of different grades of AIS-head injury, and a 1:1 matched LWMH:UH cohort of patients. RESULTS: Out of 14,926 patients, 11,036 (73.9%) received LMWH. Multivariate analysis showed that patients receiving LMWH had a decreased risk of mortality (OR 0.81, 95% CI 0.67-0.97, p < 0.001) but a similar risk of VTE (OR 0.83, 95% CI 0.63-1.08). Analysis according to head-AIS showed that LMWH was associated with a decreased risk of PE in patients AIS-3 but not in AIS 4 or 5. In a 1:1 matched cohort of LMWH:UH patients, the risk of PE, DVT and VTE were all similar but LMWH continued to be associated with a decreased risk of mortality (OR 0.81, CI 0.67-0.97, p = 0.023). CONCLUSION: LMWH was associated with a decreased risk of overall mortality and reduced risk of PE compared to UH among geriatric patients with a severe head injury.

INTRODUCTION: Despite the shift toward liberal primary anastomosis in penetrating colon injuries, some surgeons recommend a protective diverting ostomy (DO) proximal to the anastomosis. This study evaluates the effect of DO on outcomes in patients undergoing colon resection and anastomosis following penetrating trauma. METHODS: The TQIP database (2013-2018) was queried for penetrating colon injuries undergoing colectomy and anastomosis. Patients receiving DO were propensity matched to patients without diverting ostomy (woDO) (1:3). Outcomes were compared between groups. RESULTS: After matching, 89 DO patients were analyzed. The DO group had more surgical site infections (32 â% vs. 21 â%; p â< â0.05) and longer hospital stay (20 [13-27] vs. 15 [9-25]; p â< â0.05) compared to the woDO group. Mortality and unplanned operations were similar between groups. CONCLUSIONS: Diverting ostomy after colon resection and anastomosis is associated with increased infectious complications without decreasing unplanned operations or mortality. Its routine role in penetrating colon trauma needs reassessment.

BACKGROUND: Motorcycle crashes pose a persistent public health problem with disproportionate rates of severe injuries and mortality. This study aims to analyze injury patterns and outcomes with regard to helmet use. We hypothesized that helmet use is associated with fewer head injuries and does not increase the risk of cervical spine injuries. METHODS: The National Trauma Data Bank was queried for all motorcycle driver crashes between 2007-2017. Univariable analysis was used to compare demographics, clinical data, injury patterns using abbreviated injury scale, and outcomes between helmeted motorcycle drivers and non-helmeted motorcycle drivers who were injured in traffic crashes. Independent factors associated with mortality were determined by regression analysis after adjustment for potential confounders. RESULTS: A total of 315,258 patients were included for analysis, 66 % of these patients were helmeted. The sample was 92.5 % male and the median age was 41 years. Non-helmeted motorcycle drivers were more likely to sustain severe head trauma (head abbreviated injury scale ≥ 3: 28.5 % vs. 13.3 %, p < 0.001), had higher intensive care unit-admission (38 % vs. 30.2 %, p<0.001), mechanical ventilation (20.1 % vs. 13 %, p<0.001) and overall mortality rates (6.2 % vs. 3.9 %, p<0.001). Cervical spine injuries occurred in 10.6 % of non-helmeted motorcycle drivers and in 9.5 % of helmeted motorcycle drivers (p<0.001). Helmet use was identified as an independent factor associated with lower mortality [OR 0.849 (0.809-0.891), p<0.001]. CONCLUSION: Helmet use is protective for severe head injuries and associated with decreased mortality. Helmet use was not associated with increased rates of cervical spine injuries. On the contrary, fewer injuries were observed in helmeted motorcycle drivers. Public health initiatives should be aimed at enforcement of universal helmet laws within the United States and across the world.

PURPOSE: Patients with traumatic brain injury (TBI) are at high risk for venous thromboembolism (VTE). The aim of the present study is to identify factors independently associated with VTE events. Specifically, we hypothesized that the mechanism of penetrating head trauma might be an independent factor associated with increased VTE events when compared with blunt head trauma. METHODS: The ACS-TQIP database (2013-2019) was queried for all patients with isolated severe head injuries (AIS 3-5) who received VTE prophylaxis with either unfractionated heparin or low-molecular-weight heparin. Transfers, patients who died within 72 h and those with a hospital length of stay < 48 h were excluded. Multivariable analysis was used as the primary analysis to identify independent risk factors for VTE in isolated severe TBI. RESULTS: A total of 75,570 patients were included in the study, 71,593 (94.7%) with blunt and 3977 (5.3%) with penetrating isolated TBI. Penetrating trauma mechanism (OR 1.49, CI 95% 1.26-1.77), increasing age (age 16-45: reference; age > 45-65: OR 1.65, CI 95% 1.48-1.85; age > 65-75: OR 1.71, CI 95% 1.45-2.02; age > 75: OR 1.73, CI 95% 1.44-2.07), male gender (OR 1.53, CI 95% 1.36-1.72), obesity (OR 1.35, CI 95% 1.22-1.51), tachycardia (OR 1.31, CI 95% 1.13-1.51), increasing head AIS (AIS 3: reference; AIS 4: OR 1.52, CI 95% 1.35-1.72; AIS 5: OR 1.76, CI 95% 1.54-2.01), associated moderate injuries (AIS = 2) of the abdomen (OR 1.31, CI 95% 1.04-1.66), spine (OR 1.35, CI 95% 1.19-1.53), upper extremity (OR 1.16, CI 95% 1.02-1.31), lower extremity (OR 1.46, CI 95% 1.26-1.68), craniectomy/craniotomy or ICP monitoring (OR 2.96, CI 95% 2.65-3.31) and pre-existing hypertension (OR 1.18, CI 95% 1.05-1.32) were identified as independent risk factors for VTE complications in isolated severe head injury. Increasing GCS (OR 0.93, CI 95% 0.92-0.94), early VTE prophylaxis (OR 0.48, CI 95% 0.39-0.60) and LMWH compared to heparin (OR 0.74, CI 95% 0.68-0.82) were identified as protective factors for VTE complications. CONCLUSION: The identified factors independently associated with VTE events in isolated severe TBI need to be considered in VTE prevention measures. In penetrating TBI, an even more aggressive VTE prophylaxis management may be justified as compared to that in blunt.

INTRODUCTION: There are two zones for the placement of a Resuscitative Endovascular Balloon Occlusion of the Aorta (REBOA) in trauma patients: above the mesenteric vessels (Zone-1) or below the renal arteries (Zone-3). Zone-1 REBOA diverts blood away from the visceral organs which leads to a systemic inflammatory response and reperfusion injury. We hypothesized that patients undergoing Zone-1 REBOA placement had a higher odds of mortality. METHODS: The 2017-2019 Trauma Quality Improvement Program database was queried for patients undergoing either Zone-1 or Zone-3 REBOA. We excluded all patients with prehospital cardiac arrest. We compared Zone-1 versus Zone-3 REBOA using a 1:2 propensity-score model, matching for age, mechanism, sex, hypotension, tachycardia, blunt solid organ injury grade, pelvic fracture, and injuries to the aorta, iliac artery, iliac vein, and inferior vena cava. RESULTS: We matched 130 Zone-1 REBOA patients to 260 Zone-3 REBOA patients. There were no statistically significant differences in the matched variables (P > 0.05). Compared to Zone-3 REBOA, patients with Zone-1 REBOA who survived ≥48 h had similar rates of acute kidney injury (18.6% versus 10.9%, P = 0.19). Zone-1 REBOA patients had a higher mortality rate (71.4% versus 48.8%, P = 0.002) and mortality odds ratio (OR) (OR 1.85, OR 1.18-2.89, P = 0.007). Zone-1 REBOA remained associated with a higher odds of mortality after controlling for traumatic brain injury and injury severity score (OR 1.86, OR 1.18-2.92, P = 0.007). CONCLUSIONS: Compared to Zone-3, using a REBOA in Zone-1 is associated with higher odds of mortality. The use of REBOA Zone-1 deployment should be done with caution.

PURPOSE: In general, risk of mortality after trauma correlates with injury severity. Despite arriving in relatively stable clinical condition, however, some patients are at risk of death following mild traumatic brain injury (TBI). The study objective was delineation of patients who die in-hospital following mild isolated TBI in order to inform Emergency Department (ED) disposition and care discussions with patients and families. METHODS: In this retrospective cohort study, patients from the National Trauma Data Bank (NTDB) (2007-2018) were included if they were injured by blunt trauma and sustained a mild TBI (defined as Head Abbreviated Injury Scale [AIS] score of 1 or 2 and arrival Glasgow Coma Scale [GCS] score of 13-15). Exclusions were severe associated injuries (extracranial AIS > 2); transfers; and missing data. Patients were defined by in-hospital mortality: Survivors vs. Mortalities. Demographics, clinical/injury data, and the outcomes were collected and compared with univariate analysis. Multivariate analysis established independent factors associated with in-hospital mortality following mild TBI. RESULTS: In total, 932,107 patients (10% of NTDB population) met study criteria: 928,542 (99.6%) Survivors and 3,565 (0.4%) Mortalities. In general, comorbidities (including home anticoagulation, cardiac disease, and diabetes mellitus) were significantly more common among patients who died (p < 0.001), although drug and alcohol intoxication on arrival were more common among Survivors (16% vs. 7%, p < 0.001; 13% vs. 10%, p < 0.001). In terms of insurance status, Private/Commercial insurance was more common among Survivors (39% vs. 20%, p < 0.001) while Governmental Insurance was more common among Mortalities (55% vs. 36%, p < 0.001). On multivariate analysis, age ≥ 65 was most strongly associated with death (OR 26.43, p < 0.001), followed by ED intubation (OR 10.08, p < 0.001), admission hypotension (OR 4.55, p < 0.001), and comorbidities, particularly end-stage renal disease (ESRD) (OR 3.03, p < 0.001) and immunosuppression (OR 2.18, p < 0.001). CONCLUSIONS: Survivors differed substantially from Mortalities after mild TBI in terms of comorbidities, intoxicants, and insurance status. Independent variables most strongly associated with in-hospital death following mild head injury included age ≥ 65, intubation in the ED, admission hypotension, and comorbidities (particularly ESRD and immunosuppression). Increased clinical vigilance, including a mandatory period of clinical observation, for patients with these risk factors should be considered to optimize outcomes and potentially mitigate death after mild TBI.
RESUMEN
BACKGROUND: Combat-related gunshot wounds (GSW) may differ from those found in civilian trauma centers. Missile velocity, resources, logistics, and body armor may affect injury patterns and management strategies. This study compares injury patterns, management, and outcomes in isolated abdominal GSW between military (MIL) and civilian (CIV) populations. METHODS: The Department of Defense Trauma Registry (DoDTR) and TQIP databases were queried for patients with isolated abdominal GSW from 2013 to 2016. MIL patients were propensity score matched 1:3 based on age, sex, and extraabdominal AIS. Injury patterns and in-hospital outcomes were compared. Initial operative management strategies, including selective nonoperative management (SNOM) for isolated solid organ injuries, were also compared. RESULTS: Of the 6435 patients with isolated abdominal GSW, 183 (3%) MIL were identified and matched with 549 CIV patients. The MIL group had more hollow viscus injuries (84% vs. 66%) while the CIV group had more vascular injuries (10% vs. 21%) (p < .05 for both). Operative strategy differed, with more MIL patients undergoing exploratory laparotomy (95% vs. 82%) and colectomy (72% vs. 52%) (p < .05 for both). However, no difference in ostomy creation was appreciated. More SNOM for isolated solid organ injuries was performed in the CIV group (34.1% vs. 12.5%; p < 0.05). In-hospital outcomes, including mortality, were similar between groups. CONCLUSIONS: MIL abdominal GSW lead to higher rates of hollow viscus injuries compared to CIV GSW. MIL GSW are more frequently treated with resection but with similar ostomy creation compared to civilian GSW. SNOM of solid organ injuries is infrequently performed following MIL GSW.

INTRODUCTION: Contemporary trauma literature on injuries to motorcycle passengers is scarce. The aim of this study was to examine the injury patterns and outcomes of motorcycle passengers with regard to helmet use. We hypothesized that helmet utilization affects both injury type and outcomes. METHODS: The National Trauma Data Bank was queried for all motorcycle passengers who were injured in traffic accidents. Participants were stratified according to helmet utilization into helmeted (HM) and nonhelmeted (NHM) groups. Univariate and multivariate analyses were performed to compare the injury patterns and outcomes between the groups. RESULTS: A total of 22,855 patients were included for analysis, of which 57.1% (13,049) used helmet. The median age was 41 years (IQR 26-51), 81% were female, and 16% of patients required urgent operation. NHM had higher risk of major trauma (ISS > 15: 26.8% vs 31.6%, p < 0.001). The most frequently injured body region in NHM was the head (34.6% vs 56.9%, p < 0.001), whereas in HM patients was the lower extremities (65.3% vs 56.7%, p < 0.001). NHM patients were more likely to require admission to the ICU, mechanical ventilation, and had significantly higher mortality rate (3.0% vs 6.3%, p < 0.001). The strongest predictors of mortality were GCS < 9 on admission, hypotension on admission, and severe head injury. Helmet utilization was associated with decreased odds of death (OR 0.636; 95% CI 0.531-0.762; p < 0.001). CONCLUSION: Motorcycle collisions can lead to significant injury burden and high mortality in motorcycle passengers. Middle-age females are disproportionally affected. Traumatic brain injury is the leading cause of death. Helmet use is associated with decreased risk of head injury and death.

BACKGROUND: The American College of Surgeons Committee on Trauma (ACS COT) delineates trauma center standards, one of which limits the number of injured patients admitted to nonsurgical services. Performance improvement review of nonsurgical admissions (NSAs), particularly those with Injury Severity Score (ISS) > 9, is required. OBJECTIVE: To examine trauma patients with NSA for appropriateness of admission and any potential clinical effect as a result of NSA. METHODS: All trauma patients presenting to our ACS COT-verified level 1 trauma center in Southern California (05/2021-04/2022) were retrospectively screened. Nonsurgical admissions with ISS > 9 were included without exclusions. Appropriateness and clinical impact of NSA were assessed by the Trauma Medical Director (TMD) and Associate TMD. RESULTS: Forty patients met study criteria, with a mean age of 54 years (range 5 d-99 y). The mean ISS was 19 (range 10-30). Nonsurgical admissions most commonly sustained traumatic brain injury (TBI) (n = 27, 68%) after ground level falls (GLF) (n = 32, 80%). All NSAs were evaluated by ≥1 surgical service, commonly neurosurgery (n = 33, 83%) and trauma surgery (n = 13, 33%). Sixteen patients (40%) died, 75% (n = 12) of which were secondary to catastrophic TBI. Upon detailed review, all NSAs were deemed appropriate and without potential clinical impact. CONCLUSIONS: All NSAs in this study were appropriate admissions without clinical effect from lack of surgical admission. Nonsurgical admissions were typically elderly patients with head injuries after GLF. With the anticipated increase in geriatric trauma due to our aging population, NSA with surgical consultation may be an important way to manage trauma admissions without compromising care of injured patients.

INTRODUCTION: The American College of Surgeons (ACS) delineates trauma team activation (TTA) criteria to identify seriously injured trauma patients in the field. Patients are deemed to be severely undertriaged (SU), placing them at risk for adverse outcomes, when they do not meet TTA criteria but nonetheless sustain significant injuries (Injury Severity Score [ISS] ≥25). OBJECTIVES: Delineate patient demographics, injuries, and outcomes after SU. PARTICIPANTS: Trauma patients presenting to our ACS-verified Level 1 trauma center with ISS ≥25 were included (11/2015-03/2022). Transfers and private vehicle transports were excluded. Patients were dichotomized and compared by trauma arrival level: TTA (Appropriately Triaged, AT) vs routine consults (SU). RESULTS: Study criteria were satisfied by 1653 patients: 1375 (83%) AT and 278 (17%) SU. Severely undertriaged patients were older than AT patients (47 vs 36 years, P < .001). Severely undertriaged occurred almost exclusively following blunt trauma (96% vs 71%, P < .001). Injury Severity Score was lower following SU than AT (29 vs 32, P < .001). The most common severe injuries (Abbreviated Injury Scale score [AIS] ≥3) among the SU group were in the Chest (n = 179, 64%). Severely undertriaged patients necessitated emergent intubation (n = 34, 12%), surgery (n = 59, 21%), and angioembolization (n = 22, 8%) at high rates. Severely undertriaged mortality was n = 40, 14%. CONCLUSION: Severely undertriaged occurred among a substantial proportion of ISS ≥25 patients, predominately following blunt trauma. Severe chest injuries were most likely to evade capture. Rates of intubation, emergent intervention, and in-hospital mortality were high after SU. Efforts should be made to identify such patients in the field as they may benefit from TTA.

INTRODUCTION: Colon and rectal injuries have been diverted at higher rates in military trauma compared with civilian injuries. However, in the last few years, there has been a shift to more liberal primary anastomosis in wartime injuries. The purpose of this study was to compare the management and outcomes in colorectal gunshot wounds (GSWs) between military and civilian settings. METHODS: The study included Department of Defense Trauma Registry and Trauma Quality Improvement Program database patients who sustained colorectal GSWs, during the period 2013 to 2016. Department of Defense Trauma Registry patients were propensity score matched 1:3 based on age, sex, grade of colorectal injury, and extra-abdominal Abbreviated Injury Scale. Patients without signs of life, transfers from an outside hospital, and nonspecific colorectal Organ Injury Scale were excluded. Operative management and outcomes were compared between the two groups. Subanalysis was performed on the military cohort to identify any differences in the use primary repair, colectomy, or fecal diversion based upon military affiliation or North Atlantic Treaty Organization status. RESULTS: Overall, there were 2,693 patients with colorectal GSWs; 60 patients in the military group were propensity score matched with 180 patients in the civilian group. Overall, colectomy was the most common procedure performed (72.1%) and was used more frequently in the military group (83.3% vs. 68.3%; p < 0.05). However, the rate of fecal diversion was similar in the two groups (23.3% vs. 27.8%; p = 0.500). Among those in the military group, no difference was seen in primary repair, colectomy, or fecal diversion based upon military affiliation or North Atlantic Treaty Organization status. The rates of in-hospital compilations and mortality were similar between the military and civilian groups. CONCLUSION: The severity of GSW colorectal injuries in military and civilian trauma was comparable. There was no significant difference in terms of fecal diversion, mortality, and complications between groups. Military personnel are treated similarly regardless of affiliation. LEVEL OF EVIDENCE: Therapeutic/Care Management; Level III.

INTRODUCTION: Data concerning injuries resulting from physical force during legal interventions are scarce. The purpose of this study was to examine manhandling injuries occurring in both civilian suspects and law enforcement officials (LEO). METHODS: Retrospective cross-sectional study using data from the National Trauma Data Bank. All patients who sustained manhandling injuries during legal interventions were identified using ICD-10 e-codes. The study groups were injured civilian suspects and LEO. The primary outcomes were type and severity of injuries among the groups. RESULTS: A total of 507 patients were included in the study, 426 (84.0%) civilians and 81 (16.0%) LEO. Overall, median age was 37 years (IQR: 28-48) and 90.3% were male. The median ISS was higher in civilians compared to LEO (5 [4-10] vs 4 [4-9], p = 0.023). Civilians were more likely to sustain injuries to the face (49.8% vs 35.9%, p = 0.024) and abdomen (8.3% vs 1.3%, p = 0.028). LEO were more likely to sustain tibia/fibula fractures (3.5% vs 9.9%, p = 0.019). The mortality was 1.2% (5/426) in civilians and there were no deaths in LEO. The overall complication rates and hospital length of stay were similar between the groups. CONCLUSION: Injury patterns and severity of injuries sustained from the use of physical force during legal interventions are different in civilians and law enforcement officials. Further research and more comprehensive data are warranted to better understand and prevent these injuries.

OBJECTIVE: To evaluate the impact of COVID-19 positivity on outcomes and resource utilization in the trauma population. INTRODUCTION: COVID-19 infection worsens outcomes of trauma patients, but it is not known if asymptomatic COVID-19 trauma patients have different outcomes from COVID-19-negative patients. METHODS: All trauma patients admitted to an urban level 1 trauma center between March 2020 and October 2021 were collected and reviewed for COVID-19 status. COVID-19-positive patients with symptoms or initial chest radiographs consistent with infections were excluded. Propensity score model 1:3 matched asymptomatic COVID-19-positive to COVID-19-negative trauma patients for their age, body mass index, MOA, injury severity score, SBP<90, GCS<9, and comorbidities. Outcomes included mortality, complications, and resource utilization. RESULTS: A total of 185 asymptomatic COVID-19-positive patients were matched with 554 COVID-19-negative patients. Asymptomatic COVID-19 -positive patients had higher rates of myocardial infarction and cardiac arrest (3.2% vs. 0.9%, P =0.023), higher ventilator days (3.33 vs. 1.49 days, P <0.001), ICU-length of stay [LOS (4.92 vs. 3.41 d, P =0.034)], overall LOS (11.41 vs. 7.24 d, P <0.001), and hospital charges ($ 176.505.80 vs. 107.591.93, P =0.002). CONCLUSION: Asymptomatic COVID-19 trauma patients have significantly higher rates of cardiac events, longer LOS, and higher hospital charges when compared with similar trauma patients who are COVID-19-negative.

BACKGROUND: Preperitoneal packing (PPP) has been widely accepted as a damage control technique for severe bleeding from pelvic fractures. It is supposed to work by direct compression and tamponade of the bleeding source in the pelvis and it has been suggested to be effective for both venous and arterial bleeding. However, there is little evidence to support its efficacy or the ability to place the laparotomy pads in proximity of the desired location. METHODS: Bilateral PPP was performed on 10 fresh human cadavers, followed by laparotomy and measurements of resultant pad placement in relation to critical anatomic structures. RESULTS: A total of 20 assessments of laparotomy pad placement were performed. Following completion of PPP, a midline laparotomy was performed to determine proximity and closest distance of the laparotomy pads to sites of potential bleeding in pelvic fractures. In almost all cases, the pad placement was not contiguous with the key anatomic structure with mean placement 3.9 + 1.1 cm from the sacroiliac joint, 3.5 + 1.6 cm from the common iliac artery, 1.1 + 1.2 cm from the external iliac artery, 2.8 + 0.8 cm from the internal iliac artery, and 2.3 + 1.2 cm from the iliac bifurcation. Surgeon experience resulted in improved placement relative to the sacroiliac joint, however the pads still did not directly contact the target point. CONCLUSION: This human cadaver study has shown that PPP, even in experienced hands, may not be placed in significant proximity of anatomical structures of interest. The role of PPP needs to be revisited with better clinical or human cadaver studies.
