ABSTRACT
OBJECTIVE: This study sought to elucidate clinical and imaging findings predictive for malperfusion syndrome after blunt thoracic aortic injury (BTAI). SUMMARY BACKGROUND DATA: There is limited literature on malperfusion syndrome after BTAI and the timing of thoracic endovascular aortic repair (TEVAR) in patients with this condition has not been defined. METHODS: A retrospective analysis of prospectively collected data of patients with BTAI treated between January 2021 and October 2023. Clinical and thoracic aortic (TA) imaging data, time to TEVAR, in-hospital death, and malperfusion/reperfusion sequelae (paraplegia, renal/visceral/limb ischemia, and compartment syndromes) were assessed. Correlations between clinical and imaging findings, time to TEVAR, and outcomes were evaluated. RESULTS: Of the 19,203 trauma patients evaluated, 13,717 (71%) had blunt injuries and 77 (0.6%) had BTAI. The majority (67.5%) were male with a median age of 40 years (IQR:33-55). TEVAR was performed in 42 (54.5%) patients. Seven (9.1%) patients presented with clinical and TA imaging criteria for traumatic thoracic aortic coarctation (TTAC), including diminished/absent femoral pulses and TA luminal narrowing of 50-99%. The median time to TEVAR was 9 (IQR:5-32), 11, and 4 hours for all non-TTAC and TTAC BTAI patients, respectively (P=0.037). Only TTAC patients presented/developed malperfusion/reperfusion sequelae. In-hospital mortality rates were 7.8%, 5.8%, and 29% for all non-TTAC and TTAC BTAI patients, respectively (P=0.09). Aortic-related mortality occurred in only two (2.6%) TTAC patients.. CONCLUSIONS: Patients with clinical and TA imaging manifestations of TTAC are predisposed to malperfusion/reperfusion sequelae if TEVAR is delayed. We recommend the emergent repair of all BTAIs with TTAC.
ABSTRACT
INTRODUCTION: Augmented renal clearance (ARC) is prevalent in trauma populations. Identification is underrecognized by calculated creatinine clearance or estimated glomerular filtration rate equations. Predictive scores may assist with ARC identification. The goal of this study was to evaluate validity of the ARCTIC score and ARC Predictor to predict ARC in critically ill trauma patients. METHODS: This single center, retrospective study was performed at an academic level 1 trauma center. Critically ill adult trauma patients undergoing 24-h urine-collection were included. Patients with serum creatinine >1.5 mg/dL, kidney replacement therapy, suspected rhabdomyolysis, chronic kidney disease, or inaccurate urine collection were excluded. Sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) for ARCTIC Score and ARC Predictor were calculated. Receiver operating characteristic curves were created for ARCTIC score and ARC Predictor models. RESULTS: One-hundred and twenty-two patients with ARC and 78 patients without ARC were included. The ARCTIC score sensitivity, specificity, PPV, and NPV were 89%, 54%, 75%, and 75%, respectively. The ARC Predictor demonstrated sensitivity, specificity, PPV, and NPV of 77%, 88%, 91%, and 71%, respectively. Regression analyses revealed both ARCTIC score ≥6 and ARC Predictor threshold >0.5 as significant risk factors for ARC in presence of traumatic brain injury, obesity, injury severity score, and negative nitrogen balance (ARCTIC ≥6: odds ratio 8.59 [95% confidence interval 3.90-18.92], P < 0.001; ARC Predictor >0.5: odds ratio 20.07 [95% confidence interval 8.53-47.19], P < 0.001). CONCLUSIONS: These findings corroborate validity of two pragmatic prediction tools to identify patients at high risk of ARC. Future studies evaluating correlations between ARCTIC score, ARC Predictor, and clinical outcomes are warranted.

INTRODUCTION: Hospital overcrowding is common and can lead to delays in intensive care unit (ICU) admission, resulting in increased morbidity and mortality in medical and surgical patients. Data on delayed ICU admission are limited in the postsurgical trauma cohort. Damage control laparotomy with temporary abdominal closure (DCL-TAC) for severely injured patients is often followed by an aggressive early resuscitation phase, usually occurring in the ICU. We hypothesized that patients who underwent DCL-TAC with initial postanesthesia care unit (PACU) stay would have worse outcomes than those directly admitted to ICU. METHODS: A retrospective chart review identified all trauma patients who underwent DCL-TAC at a level 1 trauma center over a 5 y period. Demographics, injuries, and resuscitation markers at 12 and 24 h were collected. Patients were stratified by location after index laparotomy (PACU versus ICU) and compared. Outcomes included composite morbidity and mortality. Multivariable logistic regression was performed. RESULTS: Of the 561 patients undergoing DCL-TAC, 134 (24%) patients required PACU stay due to ICU bed shortage, and 427 (76%) patients were admitted directly to ICU. There was no difference in demographics, injury severity score, time to resuscitation, complications, or mortality between PACU and ICU groups. Only 46% of patients were resuscitated at 24 h; 76% underwent eventual primary fascial closure. Under-resuscitation at 24 h (adjusted odds ratio [AOR] 0.55; 95% confidence interval [CI] 0.31-0.95, P = 0.03), increased age (AOR 1.04; 95% CI 1.02-10.55, P < 0.0001), and increased injury severity score (AOR 1.04; 95% CI 1.02-1.07, P < 0.0001) were associated with mortality on multivariable logistic regression. The median time in PACU was 3 h. CONCLUSIONS: PACU hold is not associated with worse outcomes in patients undergoing DCL-TAC. While ICU was designed for the resuscitation of critically ill patients, PACU is an appropriate alternative when an ICU bed is unavailable.

OBJECTIVE: Penetrating carotid artery injuries (PCAI) are significantly morbid and deadly, often presenting in extremis with associated injuries and central nervous system deficit. Repair may be challenging with arterial reconstruction vs ligation role poorly defined. This study evaluated contemporary outcomes and management of PCAI. METHODS: PCAI patients in the National Trauma Data Bank from 2007 to 2018 were analyzed. Outcomes were compared between repair and ligation groups after additionally excluding external carotid injuries, concomitant jugular vein injuries, and head/spine Abbreviated Injury Severity score of ≥3. Primary end points were in-hospital mortality and stroke. Secondary end points were associated injury frequency and operative management. RESULTS: There were 4723 PCAI (55.7% gunshot wounds, 44.1% stab wounds). Gunshot wounds more frequently had associated brain (73.8% vs 19.7%; P < .001) and spinal cord (7.6% vs 1.2%; P < .001) injuries; stab wounds more frequently had jugular vein injuries (19.7% vs 29.3%; P < .001). The overall in-hospital mortality was 21.9% and the stroke rate was 6.2%. After exclusion criteria, 239 patients underwent ligation and 483 surgical repair. Ligation patients had lower presenting Glasgow Coma Scale (GCS) than repair patients (13 vs 15; P = .010). Stroke rates were equivalent (10.9% vs 9.3%; P = .507); however, in-hospital mortality was higher after ligation (19.7% vs 8.7%; P < .001). In-hospital mortality was higher in ligated common carotid artery injuries (21.3% vs 11.6%; P = .028) and internal carotid artery injuries (24.5% vs 7.3%; P = .005) compared with repair. On multivariable analysis, ligation was associated with in-hospital mortality, but not with stroke. A history of neurological deficit before injury lower GCS, and higher Injury Severity Score (ISS) were associated with stroke; ligation, hypotension, higher ISS, lower GCS, and cardiac arrest were associated with in-hospital mortality. CONCLUSIONS: PCAI are associated with a 22% rate of in-hospital mortality and a 6% rate of stroke. In this study, carotid repair was not associated with a decreased stroke rate, but did have improved mortality outcomes compared with ligation. The only factors associated with postoperative stroke were low GCS, high ISS, and a history of neurological deficit before injury. Beside ligation, low GCS, high ISS, and postoperative cardiac arrest were associated with in-hospital mortality.

INTRODUCTION: Traumatic injuries to the radial and/or ulnar arteries represent a subset of arterial injuries. In the absence of injury to both forearm arteries, treatment was historically ligation if perfusion was maintained to the hand via the uninjured vessels or adequate collateral vessels. We sought to determine management of traumatic forearm arterial injuries in 2019 and to identify risk factors for major upper extremity amputation. METHODS: The American College of Surgeons Trauma Quality Improvement Program database was queried by International Classification of Diseases 10 code for patients with traumatic radial and/or ulnar artery injuries within the year 2019. Patient demographics, Injury Severity Score, time to operating room, type of repair, outcomes, and mortality were collected. Multivariable logistic regression was used to identify risk factors for major upper extremity amputation. RESULTS: A total of 4048 patients with traumatic radial and/or ulnar artery injuries were identified. A total of 1907 radial artery operations were performed including repair (59%), ligation (29%), and interposition bypass (12%). A total of 1637 ulnar artery operations were completed including repair (67%), ligation (21%), and interposition bypass (12%). Major upper extremity amputation occurred in 0.6%. Older age (adjusted odds ratio [AOR]: 1.014, 95% confidence interval [CI]: 1.004-1.024, P = 0.0048), blunt mechanism (AOR: 2.457, 95% CI: 1.730-3.497, P < 0.0.0001), and ipsilateral radial and ulnar artery injury (AOR: 2.148, 95% CI: 1.298-3.553, P = 0.0029) were associated with major amputation. Surgical revascularization, time to operating room, fasciotomy, and compartment syndrome were not associated with major amputation, but this may be secondary to Type II error. CONCLUSIONS: In the operating room, radial and ulnar artery injuries were managed more often with restoration of flow versus ligation. Older age, blunt mechanism, and ipsilateral radial and ulnar artery injury were associated with major amputation. Amputation rate was low at 3% overall and 0.6% for amputation of the hand or a more proximal level. Upper extremity fracture, upper extremity nerve injury, and ipsilateral radial and ulnar artery injury were associated with need for revision operation.

INTRODUCTION: Trauma systems continue to evolve to create the best outcomes possible for patients who have undergone traumatic injury. OBJECTIVE: This review aims to evaluate the existing research on outcomes based on field triage to a Level 1 trauma center (L1TC) compared to other levels of hospitals and nontrauma centers. METHODS: A structured literature search was conducted using PubMed, CINAHL, Embase, and the Cochrane Database. Studies analyzing measures of morbidity, mortality, and cost after receiving care at L1TCs compared to lower-level trauma centers and nontrauma centers in the United States and Canada were included. Three independent reviewers reviewed abstracts, and two independent reviewers conducted full-text review and quality assessment of the included articles. RESULTS: Twelve thousand five hundred fourteen unique articles were identified using the literature search. 61 relevant studies were included in this scoping review. 95.2% of included studies were national or regional studies, and 96.8% were registry-based studies. 72.6% of included studies adjusted their results to account for injury severity. The findings from receiving trauma care at L1TCs vary depending on severity of injury, type of injury sustained, and patient characteristics. Existing literature suffers from limitations inherent to large de-identified databases, making record linkage between hospitals impossible. CONCLUSIONS: This scoping review shows that the survival benefit of L1TC care is largest for patients with the most severe injuries. This scoping review demonstrates that further research using high-quality data is needed to elucidate more about how to structure trauma systems to improve outcomes for patients with different severities of injuries and in different types of facilities.

INTRODUCTION: Patients with traumatic brain injury (TBI) are at risk for developing venous thromboembolic complications. Previous work suggests venous thromboembolism (VTE) prophylaxis with low molecular weight heparin (LMWH) is protective compared to unfractionated heparin (UH) in trauma patients. The purpose of this study was to evaluate the role of body mass index (BMI) and type of pharmacological VTE prophylaxis in patients who develop VTE with severe TBI. METHODS: Patients with a severe TBI who received VTE prophylaxis were queried from the 2019 American College of Surgeons Trauma Quality Improvement Program database. Demographics, injury characteristics, timing of VTE prophylaxis, and BMI were collected. Outcome measures include VTE, mortality, and neurosurgical interventions. RESULTS: Of the 39,520 patients with severe TBI included in the study, 25,671 received LMWH and 13,849 received UH. Multivariable logistic regression found patients with a BMI 25-29.9 kg/m2 (odds ratio [OR] 1.375; 95% confidence interval [CI] 1.180-1.603; P < 0.0001) and a BMI>30 kg/m2 (OR 1.831; 95% CI 1.570-2.137; P < 0.0001) were independent predictors of VTE. Patients with BMI of 25-29.9 kg/m2 (OR 1.145; 95% CI 1.016-1.289; P = 0.0265) have a higher risk of mortality. For every hour delay in initiation to VTE prophylaxis, patients were 0.2% more likely to develop VTE (OR 1.002; 95% CI 1.002-1.003; P < 0.0001). Patients treated with UH were more likely to develop VTE complications (OR 1.085; 95% CI 1.058-1.112; P < 0.0001) and have increased mortality (OR 1.116; 95% CI 1.094-1.139; P < 0.0001), regardless of BMI and time to initiation of prophylaxis, compared to patients treated with LMWH. CONCLUSIONS: In patients with severe TBI, higher BMI was associated with an increased risk of VTE and death. Delay in VTE prophylaxis initiation was associated with an increased risk of VTE. LMWH had a protective association with VTE.

INTRODUCTION: We aim to study the association between state child access prevention (CAP) and overall firearm laws with pediatric firearm-related mortality. METHODS: The Centers for Disease Control and Prevention Web-based Injury Statistics Query and Reporting System was queried for pediatric (aged < 18 y) all-intent (accidental, suicide, and homicide) firearm-related crude death rates (CDRs) among the 50 states from 1999 to 2019. States were into three groups: Always CAP (throughout the 20-year period), Never CAP, and New CAP (enacted CAP during study period). We used the Giffords Law Center Annual Gun Law Scorecard (A, B, C, D, F) to group states into strict (A, B) and lenient (C, D, F) firearm laws. A scatter plot was constructed to display state CDR based on CAP laws by year. The top 10 states by CDR per year were tabulated based on CAP law status. Wilcoxon rank-sum was used to compare CDR between strict and lenient scorecard states in 2019. RESULTS: There were 12 Always CAP, 21 Never CAP, and 17 New CAP states from 1999 to 2019. No states changed from CAP laws to no CAP laws. Never CAP and New CAP states dominated the high outliers in CDR compared to Always CAP. The top 10 states with the highest CDR per year were most commonly Never CAP. Strict firearm laws states had lower median CDR in 2019 than lenient states (0.79 [0-1.67] versus 2.59 [1.66-3.53], P = 0.007). CONCLUSIONS: Stricter overall gun laws are associated with three-fold lower all-intent pediatric firearm-related deaths. For 2 decades, the 10 states with the highest CDR were almost universally those without CAP laws. Our findings support the RAND Gun Policy in America initiative's claims on the importance of CAP laws in reducing suicide, unintentional deaths, and violent crime among children, but more research is needed.

BACKGROUND: The American Association for the Surgery of Trauma (AAST) appendicitis severity grading criteria use independent subscales for radiologists (Rad), surgeons (Surg), and pathologists (Path). We reviewed the EAST Multicenter Study of the Treatment of Appendicitis in America: Acute, Perforated, and Gangrenous (MUSTANG) database to determine rates of discordance and clinical consequences of inaccuracy. MATERIALS AND METHODS: A confusion matrix was constructed for pairs among Rad, Surg, and Path. Accuracy was reported using chronologically latest diagnosis as gold standard. "Concordance" (C) was achieved when both agreed on the severity grade and "Discordance"(D) when they disagreed. A composite endpoint("COMP"= 30-d incidence of surgical site infection, abscess, wound complication, Clavien-Dindo complication, secondary intervention, ED[Emergency Department] visit, hospital readmission, and mortality) was compared between C versus D groups via χ2 test with Bonferroni correction to define statistical significance(P = 0.05/9 = 0.005). RESULTS: For each pair and diagnosis, subjects were categorized as C or D and compared for the incidence of COMP. Incidence of COMP for Surg and/or Path in C versus D: 16% versus. 26% (p = 0.006, NS by Bonferroni) for acute (A), 39% versus 33% (p = 0.39) for gangrenous (G), and 48% versus 37% (p = 0.035, NS by Bonferroni) for perforated (P). For Rad and/or Path in C versus. D: 17% versus 42% (p < 0.001) for A, 27% versus 31% (p = 0.95) for G, and 56% versus 48% (p = 0.48) for P. For C versus D: 17% versus 40% (p < 0.001) for A, 36% versus 26% (p = 0.43) for G, and 51% versus 39% (p = 0.29) for P. CONCLUSIONS: In appendicitis treated by appendectomy, surgeons are most accurate at diagnosing acute appendicitis and least accurate at diagnosing gangrenous. Radiologists are less accurate for all categories. When the surgeon is wrong, clinical outcomes are not significantly worse. However, when the radiologist is wrong about acute appendicitis, patients have worse clinical outcomes.

OBJECTIVE: Inferior vena cava (IVC) injuries have a high mortality rate that may be related to the location of injury and type of repair. Previous studies have been either single center series or database studies lacking granular detail. These have reported conflicting results. We aimed to perform a systematic review and meta-analysis of published literature evaluating ligation versus repair. METHODS: Studies published in English on MEDLINE or EMBASE from 1946 through October 2018 were examined to evaluate mortality among patients treated with ligation versus repair of IVC injuries. Studies were included if they provided mortality associated with ligation versus repair and reported IVC injury by level. Risk of bias was assessed regarding incomplete and selective outcome reporting with Newcastle-Ottawa score of 7 or higher to evaluate study quality. We used a random-effects model with restricted maximum likelihood estimation method in R using the Metafor package to evaluate outcomes. RESULTS: Our systematic review identified 26 studies, of which 14 studies, including 855 patients, met our inclusion criteria for meta-analysis. IVC ligation was associated with higher mortality than IVC repair (OR: 3.12, P < 0.01, I2â¯=â¯49%). Ligation of infrarenal IVC injuries was not statistically associated with mortality (OR: 3.13, Pâ¯=â¯0.09). Suprarenal injury location compared to infrarenal (OR 3.11, P < 0.01, I2â¯=â¯28%) and blunt mechanism compared to penetrating (OR: 1.91, Pâ¯=â¯0.02, I2â¯=â¯0%) were also associated with higher mortality. CONCLUSIONS: In this meta-analysis, ligation of IVC injuries was associated with increased mortality compared to repair, but not specifically for infrarenal IVC injuries. Suprarenal IVC injury, and blunt mechanism was associated with increased mortality compared to infrarenal IVC injury and penetrating mechanism, respectively. Data are limited regarding acute renal injury and venous thromboembolic events after IVC ligation and may warrant multicenter studies. Standardized reporting of IVC injury data has not been well established and is needed in order to enable comparison of outcomes across institutions. In particular, reporting of injury location, severity, and repair type should be standardized. A contemporary prospective, multicenter study is needed in order to definitively compare surgical technique.

OBJECTIVE: Mycotic aortic aneurysms and aortic graft infections (aortic infections [AIs]) are rare but highly morbid conditions. Open surgical repair is the "gold standard" treatment, but endovascular repair (EVR) is increasingly being used in the management of AI because of the lower operative morbidity. Multiple organisms are associated with AI, and bacteriology may be an important indication of mortality. We describe the bacteriology and associated outcomes of a group of patients treated with an EVR-first approach for AI. METHODS: All patients who underwent EVR for native aortic or aortic graft infections between 2005 and 2016 were retrospectively reviewed. Primary end points were 30-day mortality and overall mortality. The primary exposure variable was bacteria species. Logistic regression analysis was used to determine association with mortality. Kaplan-Meier survival analysis was used to estimate survival. RESULTS: A total of 2038 EVRs were performed in 1989 unique and consecutive patients. Of those, 27 patients had undergone EVR for AI. Thirteen presented ruptured (48%). Eighteen (67%) were hemodynamically unstable. Ten had a gastrointestinal bleed (37%), whereas others presented with abdominal pain (33%), fever (22%), chest or back pain (18.5%), and hemothorax (3.7%). Twenty patients had a positive blood culture (74%), with the most common organism being methicillin-resistant Staphylococcus aureus (MRSA) isolated in 37% (10). Other organisms were Escherichia coli (3), Staphylococcus epidermidis (2), Streptococcus (2), Enterococcus faecalis (1), vancomycin-resistant Enterococcus (1), and Klebsiella (1). Thirteen patients had 4 to 6 weeks of postoperative antibiotic therapy, six of whom died after therapy. Fourteen were prescribed lifelong therapy; 10 died while receiving antibiotics. On univariate analysis for mortality, smoking history (P = .061) and aerodigestive bleeding on presentation (P = .109) approached significance, whereas MRSA infection (P = .001) was strongly associated with increased mortality. On multivariate analysis, MRSA remained a strong, independent predictor of mortality (adjusted odds ratio, 93.2; 95% confidence interval, 1.9-4643; P = .023). Overall 30-day mortality was 11%, all MRSA positive. At mean follow-up of 17.4 ± 28 months, overall mortality was 59%. Overall survival at 1 year, 3 years, and 5 years was 49%, 31%, and 23%. Kaplan-Meier survival analysis demonstrated that MRSA-positive patients had a significantly lower survival compared with other pathogens (1-year, 20% vs 71%; 5-year, 0% vs 44%; P = .0009). CONCLUSIONS: In our series of AI, the most commonly isolated organism was MRSA. MRSA is highly virulent and is associated with increased mortality compared with all other organisms, regardless of treatment. Given our results, EVR for MRSA-positive AI was not a durable treatment option.

BACKGROUND: Hypocalcemia is cited as a complication of massive transfusion. However, this is not well studied as a primary outcome in trauma patients. Our primary outcome was to determine if transfusion of packed red blood cells (pRBC) was an independent predictor of severe hypocalcemia (ionized calcium ≤ 3.6 mg/dL). METHODS: Retrospective, single-center study (01/2004-12/2014) including all trauma patients ≥ 18 yo presenting to the ED with an ionized calcium (iCa) level drawn. Variables extracted included demographics, interventions, outcomes, and iCa. Regression models identified independent risk factors for severe hypocalcemia (SH). RESULTS: Seven thousand four hundred and thirty-one included subjects, 716 (9.8%) developed SH within 48 h of admission. Median age: 39 (Range: 18-102), systolic blood pressure: 131 (IQR: 114-150), median Glasgow Coma Scale (GCS): 15 (IQR: 10-15), Injury Severity Score (ISS): 14 (IQR: 9-24). SH patients were more likely to have depressed GCS (13 vs 15, p < 0.0001), hypotension (23.2% vs 5.1%, p < 0.0001) and tachycardia (57.0% vs 41.9%, p < 0.0001) compared to non-SH patients. They also had higher emergency operative rate (71.8% vs 29%, p < 0.0001) and higher blood administration prior to minimum iCa [pRBC: (8 vs 0, p < 0.0001), FFP: (4 vs 0, p < 0.0001), platelet: (1 vs 0, p < 0.0001)]. Multivariable analysis revealed penetrating mechanism (AOR: 1.706), increased ISS (AOR: 1.029), and higher pRBC (AOR: 1.343) or FFP administered (AOR: 1.097) were independent predictors of SH. SH was an independent predictor of mortality (AOR: 2.658). Regression analysis identified a significantly higher risk of SH at pRBC + FFP administration of 4 units (AOR: 18.706, AUC:. 897 (0.884-0.909). CONCLUSION: Transfusion of pRBC is an independent predictor of SH and is associated with increased mortality. The predicted probability of SH increases as pRBC + FFP administration increases.

BACKGROUND: Few data exist regarding the train vs. pedestrian (TVP) injury burden and outcomes. OBJECTIVE: This study aimed to examine the epidemiology and outcomes associated with TVP injuries. METHODS: This is a retrospective National Trauma Databank study (January 2007 to July 2012) including trauma patients sustaining TVP injury. Demographics, injury data, interventions, and outcomes were abstracted. Patients injured by a train were compared to patients who sustained an automobile vs. pedestrian (AVP) injury. RESULTS: Of the 152,631 patients struck by ground transportation during the study time frame, 1863 (1.2%) were TVP. Median TVP age was 38 years (interquartile range [IQR] 24-50 years), 81.6% were male, median Injury Severity Score (ISS) was 13 (IQR 6-24). TVP patients were more severely injured (ISS 13 vs. 9; p < 0.001) and required more proximal amputations (13.4% vs. 0.2%; p < 0.001) and cavitary operations (18.2% vs. 2.8%; p < 0.001). TVP patients had higher rates of intensive care unit admission, mechanical ventilation and transfusion, longer length of stay, and higher in-hospital mortality. On multivariable logistical regression, TVP was an independent predictor for higher injury burden, ISS ≥25 (adjusted odds ratio [AOR] 1.650), immediate operative need (AOR 7.535), and complications (AOR 1.317). CONCLUSIONS: TVP is associated with a significant injury burden. These patients have a significantly higher need for immediate operation and more complicated hospital course.

For extremity soft tissue sarcomas, limb salvage is now standard of care. The extent of surgical margins is balanced with functionality of the resected limb. Although negative margins are the goal, the necessary width is unclear. Additional considerations for margin adequacy include presence of anatomic barriers such as fascia and periosteum, proximity of critical structures, receipt of adjuvant and neoadjuvant therapies, and histologic subtype. Multidisciplinary team discussion is critical for treatment planning.

BACKGROUND: Acute kidney injury (AKI) after endovascular aortic aneurysm repair (EVAR) is uncommon though carries significant morbidity. Procedural risk factors are not well established for acute renal failure (ARF) that requires initiation of dialysis. The goal of this study was to examine the impact of ARF on patients undergoing EVAR and identify risk factors for ARF using a large, national dataset. METHODS: Patients undergoing EVAR were identified from the National Surgical Quality Improvement Program (NSQIP) database over 9 years, ending in 2019. Demographics, indication for repair, comorbidities, procedural details, complications, hospital and ICU LOS, and mortality were recorded. Patients were stratified by presence of ARF and compared. Patients were further stratified by indication for EVAR and presence of ARF. Multivariable logistic regression (MLR) analysis was performed to determine the independent predictors of ARF. RESULTS: 18 347 patients were identified. Of these 234 (1.3%) developed ARF requiring dialysis. Mortality (40 vs 1.8%, P < .0001), ICU LOS (5 vs 0 days, P < .0001), and hospital LOS (11 vs 2 days, P < .0001) were all significantly increased in patients with ARF. Multivariable logistic regression identified increasing diameter, creatinine, operative time, preoperative transfusions, ASA class, emergent repair, female gender, and juxtarenal/suprarenal proximal landing zone as predictors of ARF. CONCLUSIONS: ARF after EVAR causes significant morbidity, prolongs hospitalizations, and increases mortality rates. Those patients at risk of ARF after EVAR should be closely monitored to reduce both morbidity and mortality.

BACKGROUND: Given the acuity of patients who receive MTPs and the resources they require, MTPs are a compelling target for performance improvement. This study evaluated adherence with our MTP's plasma:red blood cell ratio (FFPR) of 1:2 and platelet:red blood cell ratio (PLTR) of 1:12, to test the hypothesis that ratio adherence is associated with lower inpatient mortality. MATERIALS AND METHODS: The registry of an urban level I trauma center was queried for adult patients who received at least 6 units of packed red blood cells within 4 hours of presentation. Patients were excluded for interfacility transfer, cardiac arrest during the prehospital phase or within one hour of arrival, or for head AIS ≥5. Univariate analysis and multiple logistic regressions were performed to identify variables associated with early transfusion protocol noncompliance and the effect on inpatient mortality. RESULTS: Three hundred and eighty-three patients were included, with mean ISS of 25.9 ± 13.3 and inpatient mortality of 28.5%. Increasing age, ISS, INR, and total units of blood product transfused were associated with increased odds of mortality, while an increase in revised trauma score was associated with a decreased odds ratio of mortality. Achieving our goal ratios were protective against mortality, with OR of .451 (P = .013) and .402 (P=.003), respectively. DISCUSSION: Large proportions of critically injured patients were transfused fewer units of plasma and platelets than our MTP dictated; failure to achieve intended ratios at 4 hours was strongly associated with inpatient mortality. MTP processes and outcomes should be critically assessed on a regular basis as part of a mature performance improvement program to ensure protocol adherence and optimal patient outcome.

BACKGROUND: Trauma surgical dogma teaches that patients should have intraoperative angiography (IA) if the surgeon cannot identify a pulse in the injured extremity following a vascular repair. This study was undertaken to assess the utility of IA in trauma patients who underwent open brachial or femoral artery revascularization. METHODS: Retrospective analysis of the Prospective Observational Vascular Injury Trial (PROOVIT) database from 2013 to 2021 evaluated patients >15 years with penetrating or blunt injuries requiring operative intervention of the brachial, superficial femoral, or common femoral arteries. Prospective Observational Vascular Injury Trial data evaluated included documented pulse in the injured extremity at revascularization completion, adjunctive IA, immediate revision, and vascular reintervention during the hospitalization. RESULTS: Of the 5057 patients with vascular injury, 185 patients met our inclusion criteria. The majority were male (86.5%) with a median age, injury severity score, and systolic blood pressure of 29, 12, and 117, respectively. Of the study patients, 39% underwent IA, 14% had immediate revision, and 8% required vascular reoperation during their admission. Patients who underwent IA and with no documented palpable pulse after repair were significantly more likely to require immediate revision before leaving the operating room (22% vs 9%, P = .013) and were not more likely to require reoperation, than those who did not undergo IA (7% vs 9%, P = .613). CONCLUSIONS: Intraoperative angiography is a valuable tool for surgeons for vascular extremity trauma and is associated with a greater rate of immediate revision. Familiarity with angiographic technique is essential for vascular trauma and should be a focal point of training.

The purpose of this study was to evaluate the efficacy and safety of intragastric administration of small volumes of sodium enema solution containing phosphorus as phosphorus replacement therapy in critically ill patients with traumatic injuries who required continuous enteral nutrition. Adult patients (>17 years of age) who had a serum phosphorus concentration <3 mg/dL (0.97 mmol/L) were evaluated. Patients with a serum creatinine concentration >1.4 mg/dL (124 µmol/L) were excluded. Patients were given 20 mL of saline enema solution intragastrically, containing 34 mmol of phosphorus and mixed in 240 mL water. A total of 55% and 73% of patients who received one (n = 22) or two doses (n = 11) had an improvement in the serum phosphorus concentration, respectively. The serum phosphorus concentration increased from 2.5 [2.1, 2.8] mg/dL (0.81 [0.69, 0.90] mmol/L) to 2.9 [2.2, 3.0] mg/dL (0.94 [0.71, 0.97 mmol/L) for those who received two doses (p = 0.222). Excluding two patients with a marked decline in serum phosphorus by 1.3 mg/dL (0.32 mmol/L) resulted in an increase in the serum phosphorus concentration from 2.3 [2.0, 2.8] mg/dL (0.74 [0.65, 0.90] mmol/L) to 2.9 [2.5, 3.2] mg/dL (0.94 [0.81, 1.03] mmol/L; n = 9; p = 0.012). No significant adverse effects were noted. Our data indicated that intragastric phosphate administration using a small volume of saline enema solution improved the serum phosphorus concentrations in most patients.

BACKGROUND: American Society for Parenteral and Enteral Nutrition (ASPEN) guidelines recommend gastrostomy for patients suspected to require enteral access device for 4-6 weeks. Our hypothesis was that traumatic brain injury (TBI) patients undergoing synchronous tracheostomy/gastrostomy (SYNC) compared to tracheostomy first (DELAY) have shorter length of stay (LOS) but higher rates of unnecessary gastrostomy. METHODS: Retrospective review of TBI patients requiring tracheostomy in 2017-2022 âat a Level 1 trauma center was conducted. SYNC and DELAY patients were compared, and CoxPH analysis was performed for LOS. RESULTS: 394 patients were included [mean age: 42 (SD:18); mortality: 9 â%]. The DELAY group had longer LOS (39 vs 32 days, p â< â0.001). There was no significant difference in unnecessary gastrostomy rate between groups (p â= â0.1331). In adjusted hazard analysis, SYNC predicted shorter LOS (HR:1.54; 95 â% CI:1.20-1.98, p â< â0.001). CONCLUSIONS: Synchronous gastrostomy was associated with shorter length of stay and similar rates of unnecessary gastrostomy in TBI patients.

CONTEXT: Withdrawal of life-sustaining therapies (WDLST) in young individuals with traumatic brain injury (TBI) is an overwhelming situation often made more stressful by socioeconomic factors that shape health outcomes. Identifying these factors is crucial to developing equitable and goal-concordant care for patients and families. OBJECTIVES: We aimed to identify predictors of WDLST in young patients with 1-TBI. We hypothesized uninsured payment method, race, and co-morbid status are associated with WDLST. METHODS: We queried the 2021 Trauma Quality Improvement Program database for patients <45 years with TBI. Patients with WDLST were compared to patients without WDLST. Multivariable logistic regression (MLR) was performed. RESULTS: 61,115 patients were included, of whom 2,487 (4.1%) underwent WDLST. Patients in the WDLST cohort were older (29 vs 27, P<0.001), more likely to suffer from a penetrating mechanism (29% vs 11%, P<.0001), and have uninsured (22% vs 18%) or other payment method (5% vs 3%) when compared to the non-WDLST cohort. MLR identified age (AOR:1.019, 95% CI 1.014-1.024, P<.0001), non-Hispanic ethnicity (AOR:1.590, 95% CI 1.373-1.841, P<.0001), penetrating mechanism (AOR:3.075, 95% CI 2.727-3.467, P<.0001), systolic blood pressure (AOR: 0.992, 95% CI 0.990-0.993, P<0.0001), advanced directive (AOR:4.987, 95% CI 2.823-8.812, P<.0001), cirrhosis (AOR:3.854, 95% CI 2.641-5.625, P<.0001), disseminated cancer (AOR:6.595, 95% CI 2.370-18.357, P=0.0003), and interfacility transfer (AOR:1.457, 95% CI 1.295-1.640, P<0.0001) as factors associated with WDLST. Black patients were less likely to undergo WDLST when compared to white patients (AOR:0.687, 95% CI 0.603-0.782, P<.0001). CONCLUSION: The decision for WDLST in young patients with severe TBI may be influenced by cultural and socioeconomic factors in addition to clinical considerations.
