Abdominal aortic rupture from an impaling osteophyte following blunt trauma.

Blunt injury of the abdominal aorta is highly fatal. We present an unusual case of an osteophyte impaling the abdominal aorta treated by endovascular repair. A 77-year-old man sustained a thoracolumbar fracture-dislocation with posterior aortic rupture between his celiac and superior mesenteric artery origins. His aortic injury was treated with a stent graft, excluding the celiac origin. He was dismissed on postoperative day 6. At 6 months, he had returned to most preinjury activities, and at 2-year follow-up, he continues to have good functional outcome. Endovascular repair may be successfully employed in select aortic injuries in hemodynamically stable patients.

Evaluating the Long-Term Neurologic Sequelae Among Trauma Patients who Received Flexion-Extension Radiographs.

Introduction: This study evaluated the presence of neurologic sequelae among trauma patients after flexion-extension (F/E) radiographs. Methods: Authors of the study conducted a retrospective review of patients (age ≥ 14 years) with a Glasgow Coma Score of 15 who sustained a blunt traumatic injury and received F/E radiographs. Radiographic scans were defined as positive, negative, inconclusive, or incomplete. The neurologic status of each patient was assessed before and after the F/E radiographs, and at discharge and follow-up. Results: Of the 501 patients included in the analysis, 84.6% (n = 424) had negative F/E radiographs, and 3.2% (n = 16) had positive F/E radiographs. Ten percent (n = 51) of patients had incomplete F/E radiographs, and 2.0% (n = 10) were inconclusive due to the inability to rule out a ligamentous injury. Three patients (0.6%) had MRI-confirmed ligamentous injuries, all of which had initial incomplete F/E radiographs due to pain. No patient had a documented neurological deficit before or after the F/E exam. Three patients with an initial negative F/E radiograph returned to the clinic with symptoms of neurologic sequelae. Two of these patients had symptom resolution with no further issues at future follow-up appointments. The third patient was found to have chronic neurologic symptoms after further evaluation. Conclusions: The inclusion of F/E exams in cervical spine clearance protocols did not demonstrate any new long-term iatrogenic neurologic injuries. Consideration should be given to performing MRIs on patients with incomplete F/E radiographs that cannot rule out a ligamentous injury.

Placement of Intracranial Pressure Monitors by Non-neurosurgeons: A Follow-Up Study.

BACKGROUND: Some research suggests that physicians who are not neurosurgeons can safely place intracranial pressure (ICP) monitors. The purpose of this study was to compare intracranial pressure monitor placement complications between neurosurgeons, trauma physicians, and general surgery residents. We hypothesized that with appropriate training, general residents can safely place ICP monitors. METHODS: A 10-year retrospective chart review of all trauma patients that required ICP monitor placement between January 1, 2012, and December 31, 2021, was conducted. Comparisons were made between treatment groups. RESULTS: During the study period, 194 patients required ICP monitor placement. General surgery residents placed 94.3% of ICP monitors, 3.6% were placed by attending trauma physicians, and 2.1% by neurosurgeons. No ICP monitors were placed by attending trauma physicians or neurosurgeons between 2015 and 2018. Overall, minor complications during ICP monitor placement included device malfunction (2.7%) and inaccurate readings (.5%). There were no major complications during ICP monitor placement. Post-ICP monitor placement complications included one patient who experienced a central nervous system infection (.5%) and three patients who had mechanical problems (1.5%). No complications occurred among the neurosurgeon or attending trauma physician treatment groups. CONCLUSION: Most intracranial pressure monitors in our study sample were safely placed by surgical residents. Based on our study findings and considering the shortage and downtrend of neurosurgery specialists, ICP bolt placement needs to become a core clinical skill in surgical resident programs across the United States.

Thoracic irrigation for prevention of secondary intervention after thoracostomy tube drainage for hemothorax: A Western Trauma Association multicenter study.

BACKGROUND: Retained hemothorax (rHTX) requiring intervention occurs in up to 20% of patients who undergo chest tube (TT) placement for a hemothorax (HTX). Thoracic irrigation at the time of TT placement decreases the need for secondary intervention in this patient group but those findings are limited because of the single-center design. A multicenter study was conducted to evaluate the effectiveness of thoracic irrigation. METHODS: A multicenter, prospective, observational study was conducted between June 2018 and July 2023. Eleven sites contributed patients. Patients were included if they had a TT placed for a HTX and were excluded if: younger than 18 years, TT for pneumothorax, thoracotomy or video-assisted thoracoscopic surgery performed within 6 hours of TT, TT >24 hours after injury, TT removed <24 hours, or death within 48 hours. Thoracic irrigation was performed at the discretion of the attending. Each hemithorax was considered separately if bilateral HTX. The primary outcome was secondary intervention for HTX-related complications (rHTX, effusion, or empyema). Secondary intervention was defined as: TT placement, instillation of thrombolytics, video-assisted thoracoscopic surgery, or thoracotomy. Irrigated and nonirrigated hemithoraces were compared using a propensity weighted analysis with age, sex, mechanism of injury, Abbreviated Injury Scale chest, and TT size as predictors. RESULTS: Four hundred ninety-three patients with 462 treated hemothoraces were included, 123 (25%) had thoracic irrigation at TT placement. There were no significant demographic differences between the cohorts. Fifty-seven secondary interventions were performed, 10 (8%) and 47 (13%) in the irrigated and non-irrigated groups, respectively ( p = 0.015). Propensity weighted analysis demonstrated a reduction in secondary interventions in the irrigated cohort (odds ratio, 0.56 (0.34-0.85); p = 0.005). CONCLUSION: This Western Trauma Association multicenter study demonstrates a benefit of thoracic irrigation at the time of TT placement for a HTX. Thoracic irrigation reduces the odds of a secondary intervention for rHTX-related complications by 44%. LEVEL OF EVIDENCE: Therapeutic/Care Management; Level II.

A western trauma association multicenter comparison of mesh versus non-mesh repair of blunt traumatic abdominal wall hernias.

BACKGROUND: Blunt traumatic abdominal wall hernias (TAWH) occur in <1 % of trauma patients. Optimal repair techniques, such as mesh reinforcement, have not been studied in detail. We hypothesize that mesh use will be associated with increased surgical site infections (SSI) and not improve hernia recurrence. MATERIALS AND METHODS: A secondary analysis of the Western Trauma Association blunt TAWH multicenter study was performed. Patients who underwent TAWH repair during initial hospitalization (1/2012-12/2018) were included. Mesh repair patients were compared to primary repair patients (non-mesh). A logistic regression was conducted to assess risk factors for SSI. RESULTS: 157 patients underwent TAWH repair during index hospitalization with 51 (32.5 %) having mesh repair: 24 (45.3 %) synthetic and 29 (54.7 %) biologic. Mesh patients were more commonly smokers (43.1 % vs. 22.9 %, p = 0.016) and had a larger defect size (10 vs. 6 cm, p = 0.003). Mesh patients had a higher rate of SSI (25.5 % vs. 9.5 %, p = 0.016) compared to non-mesh patients, but a similar rate of recurrence (13.7 % vs. 10.5%, p = 0.742), hospital length of stay (LOS), and mortality. Mesh use (OR 3.66) and higher ISS (OR 1.06) were significant risk factors for SSI in a multivariable model. CONCLUSION: Mesh was used more frequently in flank TAWH and those with a larger defect size. Mesh use was associated with a higher incidence and risk of SSI but did not reduce the risk of hernia recurrence. When repairing TAWH mesh should be employed judiciously, and prospective randomized studies are needed to identify clear indications for mesh use in TAWH.

Stop the Bleed-Wait for the Ambulance or Get in the Car and Drive? A Post Hoc Analysis of an EAST Multicenter Trial.

Background: The Stop the Bleed campaign gives bystanders an active role in prehospital hemorrhage control. Whether extending bystanders' role to private vehicle transport (PVT) for urban penetrating trauma improves survival is unknown, but past research has found benefit to police and PVT. We hypothesized that for penetrating trauma in an urban environment, where prehospital procedures have been proven harmful, PVT improves outcomes compared to any EMS or advanced life support (ALS) transport.Methods: Post-hoc analysis of an EAST multicenter trial was performed on adult patients with penetrating torso/proximal extremity trauma at 25 urban trauma centers from 5/2019-5/2020. Patients were allocated to PVT and any EMS or ALS transport using nearest neighbor propensity score matching. Univariate analyses included Wilcoxon signed rank or McNemar's Test and logistic regression.Results: Of 1999 penetrating trauma patients in urban settings, 397 (19.9%) had PVT, 1433 (71.7%) ALS transport, and 169 (8.5%) basic life support (BLS) transport. Propensity matching yielded 778 patients, distributed equally into balanced groups. PVT patients were primarily male (90.5%), Black (71.2%), and sustained gunshot wounds (68.9%). ALS transport had significantly higher ED mortality (3.9% vs 1.9%, P = 0.03). There was no difference in in-hospital mortality rate, hospital LOS, or complications for all EMS or ALS only transport patients.Conclusion: Compared to PVT, ALS, which provides more prehospital procedures than BLS, provided no survival benefit for penetrating trauma patients in urban settings. Bystander education incorporating PVT for early arrival of penetrating trauma patients in urban settings to definitive care merits further investigation.

Tranexamic Acid and Pulmonary Complications: A Secondary Analysis of an EAST Multicenter Trial.

BACKGROUND: Anti-inflammatory effects of tranexamic acid (TXA) in reducing trauma endotheliopathy may protect from acute lung injury. Clinical data showing this benefit in trauma patients is lacking. We hypothesized that TXA administration mitigates pulmonary complications in penetrating trauma patients. MATERIALS AND METHODS: This is a post-hoc analysis of a multicenter, prospective, observational study of adults (18+ years) with penetrating torso and/or proximal extremity injury presenting at 25 urban trauma centers. Tranexamic acid administration in the prehospital setting or within three hours of admission was examined. Participants were propensity matched to compare similarly injured patients. The primary outcome was development of pulmonary complication (ARDS and/or pneumonia). RESULTS: A total of 2382 patients were included, and 206 (8.6%) received TXA. Of the 206, 93 (45%) received TXA prehospital and 113 (55%) received it within three hours of hospital admission. Age, sex, and incidence of massive transfusion did not differ. The TXA group was more severely injured, more frequently presented in shock (SBP < 90 mmHg), developed more pulmonary complications, and had lower survival (P < 0.01 for all). After propensity matching, 410 patients remained (205 in each cohort) with no difference in age, sex, or rate of shock. On logistic regression, increased emergency department heart rate was associated with pulmonary complications. Tranexamic acid was not associated with different rate of pulmonary complications or survival on logistic regression. Survival was not different between the groups on logistic regression or propensity score-matched analysis. CONCLUSIONS: Tranexamic acid administration is not protective against pulmonary complications in penetrating trauma patients.

Observation-first versus angioembolization-first approach in stable patients with blunt liver trauma: A WTA multicenter study.

BACKGROUND: Prior studies evaluating observation versus angioembolization (AE) for blunt liver injuries (BLT) with contrast extravasation (CE) on computed tomography imaging have yielded inconsistent conclusions, primarily due to limitations in single-center and/or retrospective study design. Therefore, this multicenter study aims to compare an observation versus AE-first approach for BLT, hypothesizing decreased liver-related complications (LRCs) with observation. METHODS: We conducted a post hoc analysis of a multicenter, prospective observational study (2019-2021) across 23 centers. Adult patients with BLT + CE undergoing observation or AE within 8 hours of arrival were included. The primary outcome was LRCs, defined as perihepatic fluid collection, bile leak/biloma, pseudoaneurysm, hepatic necrosis, and/or hepatic abscess. A multivariable logistic regression analysis was used to evaluate risk factors associated with LRCs. RESULTS: From 128 patients presenting with BLT + CE on imaging, 71 (55.5%) underwent observation-first and 57 (45.5%) AE-first management. Both groups were comparable in age, vitals, mechanism of injury, and shock index (all p > 0.05), however the AE group had increased frequency of American Association for the Surgery of Trauma Grade IV injuries (51.0% vs. 22.0%, p = 0.002). The AE cohort demonstrated increased rates of in-hospital LRCs (36.8% vs. 12.7%, p = 0.038), emergency department representation (25.0% vs. 10.0%, p = 0.025), and hospital readmission for LRCs (12.3% vs. 1.4%, p = 0.012). However, the two cohorts had similar mortality rates (5.7% vs. 5.3%, p = 0.912). After adjusting for age, ISS, and grade of liver injury, an AE-first approach had a similar associated risk of LRCs compared with observation-first management (odds ratio, 1.949; 95% confidence interval, 0.673-5.643; p = 0.219). CONCLUSION: Patients with blunt liver injury and CE undergoing an observation-first approach were associated with a similar adjusted risk of LRCs and rate of mortality compared with AE-first approach. Overall, this calls for reevaluation of the role of routine AE in blunt liver trauma patients with CE. Future prospective randomized trials are needed to confirm these findings. LEVEL OF EVIDENCE: Therapeutic/Care Management, Level IV.

Bone Anchor Fixation in the Repair of Blunt Traumatic Abdominal Wall Hernias: A Western Trauma Association Multicenter Study.

BACKGROUND: Blunt traumatic abdominal wall hernias (TAWHs) are rare but require a variety of operative techniques to repair including bone anchor fixation (BAF) when tissue tears off bony structures. This study aimed to provide a descriptive analysis of BAF technique for blunt TAWH repair. Bone anchor fixation and no BAF repairs were compared, hypothesizing increased hernia recurrence with BAF repair. METHODS: A secondary analysis of the WTA blunt TAWH multicenter study was performed including all patients who underwent repair of their TAWH. Patients with BAF were compared to those with no BAF with bivariate analyses. RESULTS: 176 patients underwent repair of their TAWH with 41 (23.3%) undergoing BAF. 26 (63.4%) patients had tissue fixed to bone, with 7 of those reinforced with mesh. The remaining 15 (36.6%) patients had bridging mesh anchored to bone. The BAF group had a similar age, sex, body mass index, and injury severity score compared to the no BAF group. The time to repair (1 vs 1 days, P = .158), rate of hernia recurrence (9.8% vs 12.7%, P = .786), and surgical site infection (SSI) (12.5% vs 15.6%, P = .823) were all similar between cohorts. CONCLUSIONS: This largest series to date found nearly one-quarter of TAWH repairs required BAF. Bone anchor fixation repairs had a similar rate of hernia recurrence and SSI compared to no BAF repairs, suggesting this is a reasonable option for repair of TAWH. However, future prospective studies are needed to compare specific BAF techniques and evaluate long-term outcomes including patient-centered outcomes such as pain and quality of life.

High-grade liver injuries with contrast extravasation managed initially with interventional radiology versus observation: A secondary analysis of a WTA multicenter study.

BACKGROUND: High-grade liver injuries with extravasation (HGLI â€‹+ â€‹Extrav) are associated with morbidity/mortality. For low-grade injuries, an observation (OBS) first-strategy is beneficial over initial angiography (IR), however, it is unclear if OBS is safe for HGLI â€‹+ â€‹Extrav. Therefore, we evaluated the management of HGLI â€‹+ â€‹Extrav patients, hypothesizing IR patients will have decreased rates of operation and mortality. METHODS: HGLI â€‹+ â€‹Extrav patients managed with initial OBS or IR were included. The primary outcome was need for operation. Secondary outcomes included liver-related complications (LRCs) and mortality. RESULTS: From 59 patients, 23 (39.0%) were managed with OBS and 36 (61.0%) with IR. 75% of IR patients underwent angioembolization, whereas 13% of OBS patients underwent any IR, all undergoing angioembolization. IR patients had an increased rate of operation (13.9% vs. 0%, p â€‹= â€‹0.049), but no difference in LRCs (44.4% vs. 43.5%) or mortality (5.6% vs. 8.7%) versus OBS patients (both p â€‹> â€‹0.05). CONCLUSION: Over 60% of patients were managed with IR initially. IR patients had an increased rate of operation yet similar rates of LRCs and mortality, suggesting initial OBS reasonable in appropriately selected HGLI â€‹+ â€‹Extrav patients.

Evaluation of Resuscitative Endovascular Balloon Occlusion of the Aorta Complications in a Community-Based Trauma Center.

BACKGROUND: Resuscitative endovascular balloon occlusion of the aorta (REBOA) is a method of management of noncompressible torso hemorrhage in trauma patients. Increased utilization has shown increased vascular complications and mortality. This study aimed to evaluate complications of REBOA placement in a community trauma setting. METHODS: A 3-year retrospective review was performed of all trauma patients that underwent REBOA placement. Data collection included demographics, injury characteristics, complications, and mortality. RESULTS: Twenty-three patients were included, and the overall mortality was 65.2%. Most patients suffered blunt trauma (73.9%), and median ISS and TRISS (survival probability) were 24 and 42.2%, respectively. The median time to REBOA placement was 22 minutes, and hemorrhagic control was achieved in all patients. The most common complication was acute kidney injury at 34.8%. There was one complication associated with placement that required vascular intervention but did not lead to limb amputation. CONCLUSION: Resuscitative endovascular balloon occlusion of the aorta was shown to have higher rates of acute kidney injury, similar rates of vascular injury, and lower rate of limb complications compared to published literature. Resuscitative endovascular balloon occlusion of the aorta remains a useful tool for trauma resuscitation without the fear of increased complications.

Evaluation of Outcomes and Treatment Options Among Trauma Patients with Abdominal Vascular Injuries.

Introduction: Abdominal vascular injuries are associated with significant morbidity and mortality. Treatment options include non-operative management, open repair, and endovascular procedures. This study aimed to characterize patients and detail treatment modalities among those who sustained a traumatic abdominal vascular injury. Methods: A six-year descriptive retrospective study was conducted at a level 1 trauma center and included all adult patients who sustained an abdominal vascular injury. Data abstracted included demographics, admitting characteristics, mechanism of injury, admitting vitals, injury details, diagnostic and treatment information, hospital course, and follow-up data. Results: Fifty-seven patients were admitted with abdominal vascular injuries, however, 14 patients sustained injuries to smaller vascular branches and were excluded. Most vascular injuries involved the iliac artery (27.9%, n = 12), abdominal aorta (25.6%, n = 11), and inferior vena cava (25.6%, n = 11). Twenty-seven percent (n = 12) of patients sustained an injury to more than one vascular structure. Thirty-four percent of patients (n = 15) died before treatment of the abdominal vascular injury. Among the 28 patients (65.1%) treated for their vascular injuries, 46.4% (n = 13) were treated with open surgery, 32.1% (n = 9) were treated non-operatively, and 21.4% (n = 6) with coil embolization. Sixty-four percent of the patients (n = 18) who survived to discharge presented for follow-up care with a mean follow-up period of 3 ± 4.1 months. There were no vascular reinterventions after discharge for patients who followed up with our hospital. Conclusions: Study findings suggested that appropriately selected cases of traumatic vascular injuries may be managed non-operatively and safely, as there were no mortalities, complications, or reinterventions among these patients.

Characteristics of Attempted and Completed Suicides During the COVID-19 Pandemic.

BACKGROUND: This study aimed to describe patients admitted for attempted or completed suicide during the COVID-19 pandemic. METHODS: A 1-year retrospective review was performed of adult patients admitted for attempted or completed suicide. RESULTS: Of the 30 patients included, most injuries involved firearms (37%) and cutting/piercing (30%). Sixty-three percent of patients presented with an Injury Severity Score ≥16, and 37% of injuries involved the head. Upon admission, an alcohol test was completed for 83% of patients, 56% of whom tested positive. Thirty percent of patients died from their injuries, with all but one involving a firearm. Most of those who survived to discharge (62%) were discharged to an inpatient behavioral health facility. DISCUSSION: The current study indicated a large proportion of suicides during the COVID-19 pandemic involved firearms and alcohol use. These findings point to the need for interventions aimed at preventing suicide and substance abuse during pandemic situations.

Should Infants with Blunt Traumatic Brain Injuries and Intracranial Hemorrhage Have Routine Repeat Imaging?

Introduction: The practice of repeat head CT imaging in infants as a distinct population is poorly studied. The purpose of this study was to evaluate the incidence and utility of repeat head CT in the infant population. Methods: A 10-year retrospective review was conducted of infants with blunt traumatic head injuries (N = 50) that presented to a trauma center. Information from the hospital trauma registry and patient medical records were extracted regarding the size and type of injury, number and results of computed tomography (CT) imaging, changes in neurological exams, and any interventions that were required. Results: Most patients (68%) had at least one repeat CT, with 26% showing progression of hemorrhage. Decreased Glasgow Coma Scale was associated with having repeat CT scans. Nearly one in four infants had a change in management associated with repeat imaging. Repeat CT scans resulted in operative interventions in 11.8% of cases and longer intensive care unit (ICU) stays in 8.8% of cases. Repeat CT scans were associated with increased hospital length of stay, but not with increased ventilator days, ICU length of stay, or mortality. Worsening bleeds were associated with mortality, but not with other hospital outcomes. Conclusions: Changes in management following repeat CT appeared to be more common in this population than in older children or adults. Findings from this study supported repeat CT imaging in infants, however, further research is needed to validate results of this study.

Geriatric Trauma Patients: Outcomes Before and After Addition of a Hospitalist Consultation.

BACKGROUND: Research has shown improvements in patient care and outcomes with addition of a rounding geriatrician. The purpose of this study was to determine if addition of a hospitalist consultation improved patient outcomes. METHODS: A retrospective review was conducted of all trauma patients, ≥65 years, before (n=481) and after (n=430) addition of a hospitalist consultant. Data included were demographics, comorbidities, injury severity, blood pressure, laboratory levels, pain control methods, ICU and ventilator requirements, complications, hospital length of stay, mortality, preexisting wishes, and 30-day readmission. RESULTS: Adding a hospitalist consultation did not improve blood glucose or blood pressure control. It decreased narcotics-only use (36.0% vs 73.8%) while increasing multimodal pain control use (51.8% vs 14.8%, P<.001) and testing of HbA1c (7% vs .6%, P<.001). There was also increased knowledge of patient resuscitation status preferences (29.1% vs 12.9%, P<.001). CONCLUSIONS: This article does not support use of routine hospitalist consultation in the geriatric trauma population. However, with study limitations, we continue to evaluate hospitalist utility and will adjust our daily rounds to more closely match prior studies.

Falls Among Older Adults During the COVID-19 Pandemic Compared to a Pre-pandemic Period: A Case-Control Study.

BACKGROUND: Little is known about how the COVID-19 pandemic impacted older adults admitted to the hospital with fall-related injuries. This research sought to determine if there was a difference in patient characteristics and hospital outcomes among older adults with fall-related injuries during the COVID-19 pandemic compared to a non-pandemic period. METHODS: A retrospective chart review of patients 65 years or older admitted for traumatic falls before and during COVID-19 was undertaken. Data abstracted included demographics, fall details, injury data, and hospital course. RESULTS: Of 1598 patients, 50.5% presented during COVID-19 (cases), and 49.5% presented pre-pandemic (controls). Fewer cases fell in rural areas (28.6% vs 34.1%, P = .018) and were transferred from outside hospitals (32.1% vs 38.2%, P = .011). More cases experienced alcohol (4.6% vs 2.4%, P = .017) and substance use disorders (1.4% vs .4%, P = .029). Fewer cases had subdural hemorrhages (11.8% vs 16.4%, P = .007), and more had pneumothoraxes (3.5% vs 1.8%, P = .032). More patients admitted during COVID-19 experienced acute respiratory failure (2.0% vs .0%, P < .001), hypoxia (1.5% vs .3%, P = .005), and delirium (6.3% vs 1.0%, P < .001). Fewer cases were discharged to skilled nursing facilities (50.8% vs 57.3%, P = .009) and more to home with services (13.1% vs 8.3%, P = .002). DISCUSSION: This study suggested there was a similar frequency of presentation for falls among older adults during the two study periods. Older adults with fall-related injuries experienced differences in presenting comorbidities, injury patterns, complications, and discharge locations during the study periods.

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.

An observation-first strategy for liver injuries with "blush" on computed tomography is safe and effective.

INTRODUCTION: The management of liver injuries in hemodynamically stable patients is variable and includes primary treatment strategies of observation (OBS), angiography (interventional radiology [IR]) with angioembolization (AE), or operative intervention (OR). We aimed to evaluate the management of patients with liver injuries with active extravasation on computed tomography (CT) imaging, hypothesizing that AE will have more complications without improving outcomes compared with OBS. METHODS: This is a prospective, multicenter, observational study. Patients who underwent CT within 2 hours after arrival with extravasation (e.g., blush) on imaging were included. Exclusion criteria included cirrhosis, nontraumatic hemorrhage, transfers from outside facilities, and pregnancy. No hemodynamic exclusion criteria were used. The primary outcome was liver-specific complications. Secondary outcomes include length of stay and mortality. Angioembolization patients were compared with patients treated without AE. Propensity score matching was used to match based on penetrating mechanism, liver injury severity, arrival vital signs, and early transfusion. RESULTS: Twenty-three centers enrolled 192 patients. Forty percent of patients (n = 77) were initially OBS. Eleven OBS patients (14%) failed nonoperative management and went to IR or OR. Sixty-one patients (32%) were managed with IR, and 42 (69%) of these had AE as an initial intervention. Fifty-four patients (28%) went to OR+/- IR. After propensity score matching (n = 34 per group), there was no difference in baseline characteristics between AE and OBS. The AE group experienced more complications with a higher rate of IR-placed drains for abscess or biloma (22% vs. 0%, p = 0.01) and an increased overall length of stay ( p = 0.01). No difference was noted in transfusions or mortality. CONCLUSION: Observation is highly effective with few requiring additional interventions. Angioembolization was associated with higher rate of secondary drain placement for abscesses or biloma. Given this, a trial of OBS and avoidance of empiric AE may be warranted in hemodynamically stable, liver-injured patient with extravasation on CT. LEVEL OF EVIDENCE: Therapeutic/Care Management; Level II.

Octogenarian Motor Vehicle Collisions: Injury Patterns Matter.

INTRODUCTION: Motor vehicle collision (MVC) is the second most common mechanism of injury among octogenarians and is on the rise. These "oldest old" trauma patients have higher mortality rates than expected. This study examined potential factors influencing this increased mortality including comorbidities, medications, injury patterns, and hospital interventions. METHODS: A 10-year retrospective review was conducted of patients aged 80 and over who were injured in an MVC. Data collected included patient demographics, comorbidities, medication use prior to injury, collision details, injury severity and patterns, hospitalization details, outcomes, and discharge disposition. RESULTS: A total of 239 octogenarian patients were identified who were involved in an MVC. Overall mortality was 18.8%. An increased mortality was noted for specific injury patterns, patients injured in a rural setting, and those who were transfused, intubated, or admitted to the ICU. No correlation was found between mortality and medications or comorbidities. CONCLUSIONS: The high mortality rate for octogenarian patients involved in an MVC was related to injury severity, type of injury, and in-hospital complications, and not due to comorbidities and prior medications.

Rodeo Trauma: Outcome Data from 10 Years of Injuries.

Introduction: There are few data addressing rodeo injury outcomes, though injury incidence has been well described. The purpose of this study was to describe rodeo-related injury patterns and outcomes. Methods: A 10-year retrospective case series was performed of patients injured in rodeo events and who were treated at an ACS-verified level I trauma center. Data regarding demographics, injury characteristics, and outcomes were summarized. Results: Seventy patients were identified. Half were injured by direct contact with rodeo stock and 34 by falls. Head injuries were most common, occurring in 38 (54.3%). Twenty injuries (28.6%) required surgery. Sixty-nine patients (98.6%) were discharged to home. There was one death. Conclusions: Head injuries were the most common injury among this cohort. Apart from one fatality, immediate outcomes after injury were good, with most patients dismissed home. Improved data collection at the time of admission may help to evaluate the success of current safety equipment use.
