Management of pediatric lower extremity vascular trauma: adult vs pediatric level I trauma centers.

BACKGROUND: Pediatric lower extremity vascular injury (PLEVI) is uncommon and the availability of granular data is sparse. This study evaluated the surgical management of PLEVIs between a Level I adult (ATC) vs pediatric (PTC) trauma center. METHODS: We performed a retrospective review of PLEVIs (< 18 years) managed surgically between 01/2009-12/2022. Demographics and outcome data were obtained. Primary outcomes included amputation and fasciotomy rates. Secondary outcomes included type of vessel repair, mortality, and hospital length of stay. RESULTS: Seventy-nine patients were identified, 41 at the ATC and 38 at the PTC, totaling 112 vessels injured. ATC patients were older (median years 16.0 vs 12.5) and almost exclusively (97.6% vs 29.0%) gunshot wounds. Vascular surgeons managed 50% of injuries at the ATC vs 73.7% at the PTC (p = 0.10). Amputations were uncommon and not significantly different between centers. Seventeen patients (44.7%) required fasciotomies at the PTC vs 21 (51.2%) at the ATC (p = 0.56). Rates of vessel repair, ligation, grafting, mortality, and hospital length of stay were not significantly different. CONCLUSIONS: PLEVI can be managed safely at ATCs and PTCs with acceptable outcomes. However, important nuances in patient triage and management need to be considered. Multi-institutional comprehensive datasets are needed. LEVEL OF EVIDENCE:  Level III.

Impact of catastrophic brain injury guidelines on organ donation rates: Results of an EAST multicenter trial.

BACKGROUND: One third of organ donors suffer catastrophic brain injury (CBI). There are no standard guidelines for the management of traumatic CBI prior to brain death, and not all trauma centers have institutional CBI guidelines. In addition, there is high variability in management between institutions with guidelines. Catastrophic brain injury guidelines vary and may include various combinations of hormone therapy, vasopressors, fluid resuscitation, and other practices. We hypothesized that centers with CBI guidelines have higher organ donation rates than those without. METHODS: This prospective, observational EAST-sponsored multicenter trial included adult (18+ years old) traumatic-mechanism CBI patients at 33 level I and II trauma centers from January 2022 to May 2023. Catastrophic brain injury was defined as a brain injury causing loss of function above the brain stem and subsequent death. Cluster analysis with linear mixed-effects model including UNOS regions and hospital size by bed count was used to determine whether CBI guidelines are associated with organ donation. RESULTS: A total of 790 CBI patients were included in this analysis. In unadjusted comparison, CBI guideline centers had higher rates of organ donation and use of steroids, whole blood, and hormone therapy. In a linear mixed-effects model, CBI guidelines were not associated with organ donation. Registered organ donor status, steroid hormones, and vasopressin were associated with increased relative risk of donation. CONCLUSION: There is high variability in management of CBI, even at centers with CBI guidelines in place. While the use of institutional CBI guidelines was not associated with increased organ donation, guidelines in this study were not identical. Hormone replacement with steroids and vasopressin was associated with increased donation. Hormone resuscitation is a common feature of CBI guidelines. Further analysis of individual practices that increase organ donation after CBI may allow for more effective guidelines and an overall increase in donation to decrease the long waiting periods for organ transplant recipients. LEVEL OF EVIDENCE: Prognostic; Level III.

Identifying Risk Factors for Poor Outcomes Following Popliteal Vascular Injuries.

BACKGROUND: Popliteal artery injuries (PAIs) may have amputation rates as high as 20%. This study focuses on identifying risk factors associated with major amputations following PAIs in a large single-center cohort. Additionally, we assess the impact of repairing or ligating concomitant popliteal vein injuries. METHODS: A retrospective chart review encompassing 2011 to 2023 was conducted at a large urban level 1 trauma center. Patients with PAIs were included. Demographics and clinical data were analyzed, and univariate and multivariate evaluations identified significant risk factors for amputation. In patients with concomitant popliteal vein injuries, we compared outcomes between those who underwent popliteal vein repair and ligation. RESULTS: One hundred eighty eight patients with PAIs were identified; 10 underwent index amputation and were excluded. Univariate analysis followed by multivariate analysis revealed that obesity (P = 0.0132) and neurologic deficits on arrival (P = 0.0096) were associated with amputation. In the subgroup with popliteal vein injuries (N = 93), there was no significant difference in amputation rates between those who had vein repair (P = 0.21) and those who underwent ligation (P = 0.84) on logistic regression analysis. Likewise, popliteal vein ligation did not impact duration of fasciotomy closure (P = 0.20) or skin graft area (P = 0.48) based on linear regression analysis. CONCLUSIONS: Our study suggests that major amputations following PAIs are more likely in obese patients with neurologic deficits. It also suggests that venous ligation in cases of concomitant popliteal vein injuries does not significantly impact early limb salvage rate. Further research is needed to determine the optimal approach for managing concomitant popliteal vein injuries.

Pancreaticoduodenectomy in high-grade pancreatic and duodenal trauma.

INTRODUCTION: High-grade pancreaticoduodenal injuries are highly morbid and may require complex surgical management. Pancreaticoduodenectomy (Whipple procedure) is sometimes utilized in the management of these injuries, but guidelines on its use are lacking. This paper aims to present our 14-year experience in management of high-grade pancreaticoduodenal injuries at our busy, urban trauma center. METHODS: A retrospective review was performed on patients (ages >15 years) presenting with high-grade (AAST-OIS Grades IV and V) injuries to the pancreas or duodenum at our Southeastern Level 1 trauma center. Inclusion criteria included high-grade injury and requirement of Whipple procedure based on surgeon discretion. Patients were divided into two groups: (1) those who underwent Whipple procedures during the index operation and (2) Whipple candidates. Whipple candidates included patients who received Whipples in a staged fashion or who would have benefited from the procedure but either died or were salvaged to another procedure. Demographics, injury patterns, management, and outcomes were compared. Primary outcome was survival to discharge. RESULTS: Of 66,272 trauma patients in this study period, 666 had pancreatic or duodenal injuries, and 20 met inclusion criteria. Of these, 6 had Whipples on the index procedure and 14 were Whipple candidates (among whom 7 had staged Whipples, 6 died before completing a Whipple, and 1 was salvaged). Median (IQR) age was 28 (22.75-40) years. Patients were 85 % male, 70 % Black. GSWs comprised 95 % of injuries. All patients had at least one concomitant injury, most commonly major vascular injury (75 %), colonic injury (65 %), and hepatic injury (60 %). In-hospital mortality among Whipple patients was 15 %. CONCLUSIONS: Complex pancreaticoduodenal injuries requiring pancreaticoduodenectomy are rare but life-threatening. In such patients, hemorrhage was the leading cause of death in the first 24 h. Approximately half underwent damage control surgery with staged Whipple Procedures. However, pancreaticoduodenectomy at the initial operation is feasible in highly selective patients, depending on the extent of injury, physiologic status, and resuscitation.

Thyrotoxicosis Presenting as an Acute Abdomen.

Abdominal pain continues to be a common chief complaint in the emergency setting. While this presentation can be non-specific, there are certain findings that warrant immediate surgical intervention. Portal venous gas on imaging in the setting of peritonitis and sepsis is one such finding. Thyrotoxicosis on the other hand is an uncommon diagnosis that is associated with non-specific symptoms resulting in delayed diagnosis, a clinical scenario that can lead to significant morbidity and mortality. Here, we present a rare case of a patient who presented with signs and symptoms of peritonitis and portal venous gas on CT scan that was taken emergently to the operating room. No intraabdominal pathology was identified. The patient was later diagnosed with thyrotoxicosis, the presumed cause of the acute abdomen presentation.

The impact of post-operative enteral nutrition on duodenal injury outcomes: A post hoc analysis of an EAST multicenter trial.

BACKGROUND: Leak following surgical repair of traumatic duodenal injuries results in prolonged hospitalization and oftentimes nil per os(NPO) treatment. Parenteral nutrition(PN) has known morbidity; however, duodenal leak(DL) patients often have complex injuries and hospital courses resulting in barriers to enteral nutrition(EN). We hypothesized EN alone would be associated with 1)shorter duration until leak closure and 2)less infectious complications and shorter hospital length of stay(HLOS) compared to PN. METHODS: This was a post-hoc analysis of a retrospective, multicenter study from 35 Level-1 trauma centers, including patients >14 years-old who underwent surgery for duodenal injuries(1/2010-12/2020) and endured post-operative DL. The study compared nutrition strategies: EN vs PN vs EN + PN using Chi-Square and Kruskal-Wallis tests; if significance was found pairwise comparison or Dunn's test were performed. RESULTS: There were 113 patients with DL: 43 EN, 22 PN, and 48 EN + PN. Patients were young(median age 28 years-old) males(83.2%) with penetrating injuries(81.4%). There was no difference in injury severity or critical illness among the groups, however there were more pancreatic injuries among PN groups. EN patients had less days NPO compared to both PN groups(12 days[IQR23] vs 40[54] vs 33[32],p = <0.001). Time until leak closure was less in EN patients when comparing the three groups(7 days[IQR14.5] vs 15[20.5] vs 25.5[55.8],p = 0.008). EN patients had less intra-abdominal abscesses, bacteremia, and days with drains than the PN groups(all p < 0.05). HLOS was shorter among EN patients vs both PN groups(27 days[24] vs 44[62] vs 45[31],p = 0.001). When controlling for predictors of leak, regression analysis demonstrated EN was associated with shorter HLOS(ß -24.9, 95%CI -39.0 to -10.7,p < 0.001). CONCLUSION: EN was associated with a shorter duration until leak closure, less infectious complications, and shorter length of stay. Contrary to some conventional thought, PN was not associated with decreased time until leak closure. We therefore suggest EN should be the preferred choice of nutrition in patients with duodenal leaks whenever feasible. LEVEL OF EVIDENCE: IV.

Management of lower extremity vascular injuries in pediatric trauma patients: 20-year experience at a level 1 trauma center.

Introduction: Pediatric lower extremity vascular injuries (LEVI) are rare but can result in significant morbidity. We aimed to describe our experience with these injuries, including associated injury patterns, diagnostic and therapeutic challenges, and outcomes. Methods: This was a retrospective review at a single level 1 trauma center from January 2000 to December 2019. Patients less than 18 years of age with LEVI were included. Demographics, injury patterns, clinical status at presentation, and intensive care unit (ICU) and hospital length of stay (LOS) were collected. Surgical data were extracted from patient charts. Results: 4,929 pediatric trauma patients presented during the 20-year period, of which 53 patients (1.1%) sustained LEVI. The mean age of patients was 15 years (range 1-17 years), the majority were Black (68%), male (96%), and most injuries were from a gunshot wound (62%). The median Glasgow Coma Scale score was 15, and the median Injury Severity Score was 12. The most commonly injured arteries were the superficial femoral artery (28%) and popliteal artery (28%). Hard signs of vascular injury were observed in 72% of patients and 87% required operative exploration. There were 36 arterial injuries, 36% of which were repaired with a reverse saphenous vein graft and 36% were repaired with polytetrafluoroethylene graft. One patient required amputation. Median ICU LOS was three days and median hospital LOS was 15 days. There were four mortalities. Conclusion: Pediatric LEVIs are rare and can result in significant morbidity. Surgical principles for pediatric vascular injuries are similar to those applied to adults, and this subset of patients can be safely managed in a tertiary specialized center. Level of evidence: Level IV, retrospective study.

TiME OUT: Time-specific machine-learning evaluation to optimize ultramassive transfusion.

BACKGROUND: Ultramassive transfusion (UMT) is a resource-demanding intervention for trauma patients in hemorrhagic shock, and associated mortality rates remains high. Current research has been unable to identify a transfusion ceiling or point where UMT transitions from lifesaving to futility. Furthermore, little consideration has been given to how time-specific patient data points impact decisions with ongoing high-volume resuscitation. Therefore, this study sought to use time-specific machine learning modeling to predict mortality and identify parameters associated with survivability in trauma patients undergoing UMT. METHODS: A retrospective review was conducted at a Level I trauma (2018-2021) and included trauma patients meeting criteria for UMT, defined as ≥20 red blood cell products within 24 hours of admission. Cross-sectional data were obtained from the blood bank and trauma registries, and time-specific data were obtained from the electronic medical record. Time-specific decision-tree models predicating mortality were generated and evaluated using area under the curve. RESULTS: In the 180 patients included, mortality rate was 40.5% at 48 hours and 52.2% overall. The deceased received significantly more blood products with a median of 71.5 total units compared with 55.5 in the survivors ( p < 0.001) and significantly greater rates of packed red blood cells and fresh frozen plasma at each time interval. Time-specific decision-tree models predicted mortality with an accuracy as high as 81%. In the early time intervals, hemodynamic stability, undergoing an emergency department thoracotomy, and injury severity were most predictive of survival, while, in the later intervals, markers of adequate resuscitation such as arterial pH and lactate level became more prominent. CONCLUSION: This study supports that the decision of "when to stop" in UMT resuscitation is not based exclusively on the number of units transfused but rather the complex integration of patient and time-specific data. Machine learning is an effective tool to investigate this concept, and further research is needed to refine and validate these time-specific decision-tree models. LEVEL OF EVIDENCE: Prognostic and Epidemiological; Level IV.

Is Traumatic Anterior Stove-In Chest Truly so Rare? A Single Institution Experience.

INTRODUCTION: The anterior stove-in chest (ASIC) is a rare form of flail chest involving bilateral rib or sternal fractures resulting in an unstable chest wall that caves into the thoracic cavity. Given ASIC has only been described in a handful of case reports, this study sought to review our institution's experience in the surgical management of ASIC injuries. METHODS: A retrospective review of patients with ASIC was conducted at our level I trauma center from 1//2021 to 3//2023. Information pertaining to patient demographics, fracture pattern, operative management, and outcomes was obtained and compared across patients in the case series. RESULTS: 6 patients met inclusion criteria, all males aged 37-78 years. 5 suffered motor vehicle collisions, and 1 was a pedestrian struck by an automobile. The median injury severity score was 28. All received ORIF within 5 days of admission, most commonly for ongoing respiratory distress. Patients 2 and 4 underwent bilateral ORIF of the ribs and sternum while patients 1, 5, and 6 underwent left-sided repair. Patient 3 required ORIF of left ribs and the sternum to stabilize their injuries. 5 of 6 patients were liberated from the ventilator and survived to discharge. CONCLUSIONS: This study demonstrates successful operative management of 6 patients with ASIC and suggests that early operative intervention with ORIF for affected segments may improve respiratory mechanics, ability to wean from the ventilator, and overall survival. Further research is needed to generate standardized guidelines for the management of this uncommon and complex thoracic injury.

Lower Extremity Vascular Injury in the Pediatric Trauma Patient: Management and Outcomes at an Adult Level I Trauma Center.

BACKGROUND: Traumatic vascular injuries of the lower extremity in the pediatric population are uncommon but can result in significant morbidity. The objective of this study is to demonstrate our experience with these injuries by describing patterns of traumatic vascular injury, the initial management, and data regarding early outcomes. METHODS: In total, 506 patients presented with lower extremity vascular injury between January 1, 2009 and January 1, 2021 to Grady Memorial Hospital, an urban, adult Level I trauma center in Atlanta, Georgia. Thirty-two of the 506 patients were aged less than 18 years and were evaluated for a total of 47 lower extremity vascular injuries. To fully elucidate the injury patterns and clinical course in this population, we examined patient demographics, mechanism of injury, type of vessel injured, surgical repair performed, and early outcomes and complications. RESULTS: The median (interquartile range) age was 16 (2) years (range, 3-17 years), and the majority were male (n = 29, 90.6%). Of the vascular injuries identified, 28 were arterial and 19 were venous. Of these injuries, 14 patients had combined arterial-venous injuries. The majority of injuries were the result of a penetrating injury (n = 28, 87.5%), and of these, all but 2 were attributed to gunshot wounds. Twenty-seven vascular interventions were performed by nonpediatric surgeons: 11 by trauma surgeons, 13 by vascular surgeons, 2 by orthopedic surgeons, and 1 by an interventional radiologist. Two patients required amputation: 1 during the index admission and 1 delayed at 3 months. Overall survival was 96.9%. CONCLUSIONS: Vascular injuries as the result of trauma at any age often require early intervention, and we believe that these injuries in the pediatric population can be safely managed in adult trauma centers with a multidisciplinary team composed of trauma, vascular, and orthopedic surgeons with the potential to decrease associated morbidity and mortality from these injuries.

Optimizing Transitions of Care and Enhancing Surgical Education on Acute Care Surgery: A Multi-Institutional Survey Study.

OBJECTIVE: Critically ill and injured patients are routinely managed on the Trauma and Acute Care Surgery (ACS) service and receive care from numerous residents during hospital admission. The Clinical Learning Environment Review (CLER) program established by the ACGME identified variability in resident transitions of care (TC) while observing quality care and patient safety concerns. The aim of our multi-institutional study was to review surgical trainees' impressions of a specialty-specific handoff format in order to optimize patient care and enhance surgical education on the ACS service. DESIGN: A survey study was conducted with a voluntary electronic 20-item questionnaire that utilized a 5 point Likert scale regarding TC among resident peers, supervised handoffs by trauma attendings, and surgical education. It also allowed for open-ended responses regarding perceived advantages and disadvantages of handoffs. SETTING: Ten American College of Surgeons-verified Level 1 adult trauma centers. PARTICIPANTS: All general surgery residents and trauma/acute/surgical critical care fellows were surveyed. RESULTS: The study task was completed by 147 postgraduate trainees (125 residents, 14 ACS fellows, and 8 surgical critical care fellows) with a response rate of 61%. Institutional responses included: university hospital (67%), community hospital-university affiliate (16%), and private hospital-university affiliate (17%). A majority of respondents were satisfied with morning TC (62.6%) while approximately half were satisfied with evening TC (52.4%). Respondees believe supervised handoffs improved TC and prevented patient care delays (80.9% and 74.8%, respectively). A total of 35% of trainees utilized the open-ended response field to highlight specific best practices of their home institutions. CONCLUSIONS: Surgical trainees view ACS morning handoff as an effective standard to provide the highest level of clinical care and an opportunity to enhance surgical knowledge. As TC continue to be a focus of certifying bodies, identifying best practices and opportunities for improvement are critical to optimizing quality patient care and surgical education.

Blunt Traumatic Abdominal Wall Hernias: An Indicator for Emergent Laparotomy?

BACKGROUND: Traumatic abdominal wall hernias (TAWH) are relatively uncommon; however, the shearing force that results in fascial disruption could indicate an increased risk of visceral injury. The aim of our study was to evaluate whether the presence of a TAWH was associated with intra-abdominal injury requiring emergent laparotomy. METHODS: The trauma registry was queried over an 8-year period (7/2012-7/2020) for adult patients with blunt thoracoabdominal trauma diagnosed with a TAWH. Those patients who were identified with a TAWH and greater than 15 years of age were included in the study. Demographics, mechanism of injury, ISS, BMI, length of stay, TAWH size, type of TAWH repair, and outcomes were analyzed. RESULTS: Overall, 38,749 trauma patients were admitted over the study period, of which 64 (.17%) had a TAWH. Patients were commonly male (n = 42, 65.6%); the median age was 39 years (range 16-79 years) and a mean ISS of 21. Twenty-eight percent had a clinical seatbelt sign. Twenty-seven (42.2%) went emergently to the operating room, the majority for perforated viscus requiring bowel resection (n = 16, 25.0%), and 6 patients (9.4%) who were initially managed nonoperatively underwent delayed laparotomy. Average ventilator days was 14 days, with a mean ICU LOS of 14 days and mean hospital LOS of 18 days. About half of the hernias were repaired at the index operation, 6 of which were repaired primarily and 10 with mesh. CONCLUSION: The presence of a TAWH alone was an indication for immediate laparotomy to evaluate for intra-abdominal injury. In the absence of other indications for exploration, nonoperative management may be safe.

Outcomes among trauma patients with duodenal leak following primary versus complex repair of duodenal injuries: An Eastern Association for the Surgery of Trauma multicenter trial.

BACKGROUND: Duodenal leak is a feared complication of repair, and innovative complex repairs with adjunctive measures (CRAM) were developed to decrease both leak occurrence and severity when leaks occur. Data on the association of CRAM and duodenal leak are sparse, and its impact on duodenal leak outcomes is nonexistent. We hypothesized that primary repair alone (PRA) would be associated with decreased duodenal leak rates; however, CRAM would be associated with improved recovery and outcomes when leaks do occur. METHODS: A retrospective, multicenter analysis from 35 Level 1 trauma centers included patients older than 14 years with operative, traumatic duodenal injuries (January 2010 to December 2020). The study sample compared duodenal operative repair strategy: PRA versus CRAM (any repair plus pyloric exclusion, gastrojejunostomy, triple tube drainage, duodenectomy). RESULTS: The sample (N = 861) was primarily young (33 years) men (84%) with penetrating injuries (77%); 523 underwent PRA and 338 underwent CRAM. Complex repairs with adjunctive measures were more critically injured than PRA and had higher leak rates (CRAM 21% vs. PRA 8%, p < 0.001). Adverse outcomes were more common after CRAM with more interventional radiology drains, prolonged nothing by mouth and length of stay, greater mortality, and more readmissions than PRA (all p < 0.05). Importantly, CRAM had no positive impact on leak recovery; there was no difference in number of operations, drain duration, nothing by mouth duration, need for interventional radiology drainage, hospital length of stay, or mortality between PRA leak versus CRAM leak patients (all p > 0.05). Furthermore, CRAM leaks had longer antibiotic duration, more gastrointestinal complications, and longer duration until leak resolution (all p < 0.05). Primary repair alone was associated with 60% lower odds of leak, whereas injury grades II to IV, damage control, and body mass index had higher odds of leak (all p < 0.05). There were no leaks among patients with grades IV and V injuries repaired by PRA. CONCLUSION: Complex repairs with adjunctive measures did not prevent duodenal leaks and, moreover, did not reduce adverse sequelae when leaks did occur. Our results suggest that CRAM is not a protective operative duodenal repair strategy, and PRA should be pursued for all injury grades when feasible. LEVEL OF EVIDENCE: Therapeutic/Care Management; Level IV.

Hepatic Arterioportal Fistula Following Liver Trauma: Case Series and Review of the Literature.

PURPOSE: Hepatic arterioportal fistula (HAPF) is an uncommon complication of hepatic trauma, which can manifest with abdominal pain and the sequelae of portal hypertension months to years after injury. The purpose of this study is to present cases of HAPF from our busy urban trauma center and make recommendations for management. METHODS: One hundred and twenty-seven patients with high-grade penetrating liver injuries (American Association for the Surgery of Trauma [AAST] - Grades IV-V) between January 2019 and October 2022 were retrospectively reviewed. Five patients were identified with an acute hepatic arterioportal fistula following abdominal trauma from our ACS-verified adult Level 1 trauma center. Institutional experience with overall surgical management is described and reviewed with the current literature. RESULTS: Four of our patients presented in hemorrhagic shock requiring emergent operative intervention. The first patient had postoperative angiography and coil embolization of the HAPF. Patients 2 through 4 underwent damage control laparotomy with temporary abdominal closure followed by postoperative transarterial embolization with gelatin sponge particles (Gelfoam) or combined Gelfoam/n-butyl cyanoacrylate. The final patient went directly for angiography and Gelfoam embolization after identification of the HAPF. All 5 patients had resolution of HAPF on follow-up imaging with continued post management for traumatic injuries. CONCLUSION: Hepatic arterioportal fistula can present as a complication of hepatic injury and manifest with significant hemodynamic aberrations. Although surgical intervention was required to achieve hemorrhage control in almost all cases, management of HAPF in the setting of high-grade liver injuries was achieved successfully with modern endovascular techniques. A multidisciplinary approach to such injuries is necessary to optimize care in the acute setting following traumatic injury.

Trends in Adolescent Firearm-Related Injury: A Time Series Analysis.

BACKGROUND: Firearm-related injury (FRI) became the leading cause of death among children/adolescents in 2019. PURPOSE: This study sought to determine changes over time in the population of adolescents affected by FRI in Atlanta, Georgia, such that high risk cohorts could be identified. RESEARCH DESIGN: City-wide retrospective cohort review. STUDY SAMPLE: Adolescent victims (age 11-21 years of age) of FRI, defined by ICD9/10 codes, in Atlanta, Georgia. DATA ANALYSIS: Descriptive, multivariate and time series analysis. RESULTS: There were 1,453 adolescent FRI victims in this time period, predominantly Black (86%) and male (86.6%). Unintentional injury was higher among ages 11-14 years (43.1%) compared to 15-17 years (10.2%) and 18-21 years (9.3%) (P < .01). FRI affecting females increased at a rate of 8.1 injuries/year (P < .01), and unintentional injuries increased at by 7.6/year (P < .01). Mortality declined from 16% in 2016 to 7.7% in 2021. CONCLUSION: Our data provides evidence for firearm policy reform. Interventions should target prevention of intentional injury among AQ4 females and seek to reverse the trend in unintentional injuries.

Risk factors for recurrence in blunt traumatic abdominal wall hernias: A secondary analysis of a Western Trauma association multicenter study.

BACKGROUND: Few studies have investigated risk factors for recurrence of blunt traumatic abdominal wall hernias (TAWH). METHODS: Twenty trauma centers identified repaired TAWH from January 2012 to December 2018. Logistic regression was used to investigate risk factors for recurrence. RESULTS: TAWH were repaired in 175 patients with 21 (12.0%) known recurrences. No difference was found in location, defect size, or median time to repair between the recurrence and non-recurrence groups. Mesh use was not protective of recurrence. Female sex, injury severity score (ISS), emergency laparotomy (EL), and bowel resection were associated with hernia recurrence. Bowel resection remained significant in a multivariable model. CONCLUSION: Female sex, ISS, EL, and bowel resection were identified as risk factors for hernia recurrence. Mesh use and time to repair were not associated with recurrence. Surgeons should be mindful of these risk factors but could attempt acute repair in the setting of appropriate physiologic parameters.

Missing Bullets: Bullet Embolization Case Series and Review of the Literature.

PURPOSE: Bullet embolization is a rare but dangerous phenomenon. Based on the location of embolization, migration of bullets can cause limb or intra-abdominal ischemia, pulmonary infarction, cardiac valve injury, or cerebrovascular accident. Bullet emboli can present a diagnostic challenge given the varied nature of complications based on location of embolization, which may not coincide with the site of initial injury. The purpose of this study is to present several cases of bullet embolization from our busy urban trauma center and make recommendations for management. METHODS: We present 3 cases of bullet embolization seen in injured patients at our Level 1 trauma center. We describe our management of these injuries and make recommendations for management in the context of our institutional experience and comment on the available literature regarding bullet embolization. RESULTS: Two of our patients presented in extremis and required operative intervention to achieve stability. The intravascular missile was discovered intraoperatively in one patient and removed in the operating room, while the missile was discovered on postoperative imaging in another patient and again removed operatively after an unsuccessful attempt at minimally invasive retrieval. Our third patient remained hemodynamically stable throughout his hospitalization and had endovascular management of his bullet embolus. CONCLUSION: Bullet emboli present a challenging complication of penetrating trauma. We recommend removal of all arterial bullet emboli and those within the pulmonary venous system. In hemodynamically stable patients, we recommend initial attempts of endovascular retrieval followed by open surgical removal. We recommend open removal in cases of hemodynamic instability.

Second Victim Syndrome in Trauma Practitioners and Other Ancillary Staff.

In health care, second victims are traumatized clinicians involved in unanticipated or untoward patient events. Programs that address second victim syndrome are sparse and its diagnosis often goes unrecognized. Consistently, literature has identified gaps in support resources, leading to compromised patient care and provider health. This project evaluates the need for second victim resources in trauma care providers at a tertiary public level 1 trauma hospital by electronically implementing a validated second victim survey over 5 weeks. Our results illustrate that second victim syndrome is prevalent among 57.1% of trauma care providers, of which 22.9% agree that second victim syndrome results in some form of undesirable work intentions.

Screening, Brief Intervention, and Referral to Treatment to Prevent Post-Traumatic Stress Disorder After Gunshot Wounds.

Screening, brief intervention, and referral to treatment (SBIRT) is an intervention originally developed to prevent and deter substance abuse. Adaptation of the SBIRT model to prevent post-traumatic stress disorder (PTSD) may potentially reduce acute stress symptoms after traumatic injury. We conducted a prospective randomized control study of adult patients admitted for gunshot wounds. Patients were randomized to intervention (INT) vs. treatment as usual (TAU) groups. INT received the newly developed SBIRT Intervention for Trauma Patients (SITP)-a 15-minute session with elements of cognitive behavioral therapy techniques. SITP took place during the index hospitalization; both groups had followup at 30 and 90 days at which time a validated PTSD screening tool, PCL-5, was administered. Most of the 46 participants were young (mean age = 30.5y), male (91.3%), and black (86.9%). At three-month follow-up, SBIRT and TAU patients had similar physical healing scores but the SBIRT arm showed reductions in PTSD symptoms.
