Shock Index is a Stronger Predictor of Outcomes in Older Compared to Younger Patients.

INTRODUCTION: The shock index (SI) is a known predictor of unfavorable outcomes in trauma. This study seeks to examine and compare the SI values between geriatric patients and younger adults. METHODS: We conducted a retrospective study of the Trauma Quality Improvement Program database from 2017 to 2019. All patients≥ 25 y with injury severity score ≥ 16 were included. Age groups were defined as 25-44 y (group A), 45-64 y (group B), and ≥65 y (group C). SI was calculated for all patients. The primary outcome was mortality and secondary outcomes were need for blood transfusion and need for major surgical intervention (consisting angiography, exploratory laparotomy, and thoracotomy). RESULTS: A total of 244,943 patients were studied. The SI was highest in group A (0.82 ± 0.33) and lowest in group C (0.62 ± 0.30) (P < 0.001). Mortality rate of group C (17%) was significantly higher than group A (9.7%) and B (11.3%) (P < 0.001). In group A, each 0.1 increase in SI was associated with mortality (odds ratio [OR] = 1.079), need for blood transfusion (OR = 1.225) and need for major surgical intervention (OR = 1.347) (P < 0.001 for all). In group C, each 0.1 increase in SI was associated with mortality (OR = 1.126), need for blood transfusion (OR = 1.318), and need for major surgical intervention (OR = 1.648) (P < 0.001 for all). The area under the curve of SI was significantly higher in group C compared to other groups for needing a major surgical intervention and need for blood transfusion (P < 0.05 for both). CONCLUSIONS: These results highlight the significance of the SI as a valuable indicator in geriatric patients with severe trauma. The findings show that SI predicts outcomes in geriatrics more strongly than in younger counterparts.

Risk factors and predictors of violence: insights from the emergency department at a level 1 trauma center in the USA.

BACKGROUND: This study aimed to assess the risk factors and predictors of violence among patients admitted to a Level 1 trauma center in a single institution. METHODS: We conducted a retrospective analysis of patients who were admitted with a history of violence between 2012 and 2016. RESULTS: A total of 9855 trauma patients were admitted, of whom 746 (7.6%) had a history of violence prior to the index admission. Patients who had history of violence were younger and more likely to be males, Black, Hispanic and covered by low-income primary payer in comparison to non-assault trauma patients (P < 0.001 for all). Multivariate logistic regression analysis showed that covariate-adjusted predictors of violence were being Black, male having low-income primary payer, Asian, drug user, alcohol intoxicated and smoker. CONCLUSIONS: Violence is a major problem among young age subjects with certain demographic, social and ethnic characteristics. Trauma centers should establish violence injury prevention programs for youth and diverse communities.

Cardiac arrest in spontaneous subarachnoid hemorrhage and associated outcomes.

OBJECTIVE: The authors sought to analyze a large, publicly available, nationwide hospital database to further elucidate the impact of cardiopulmonary arrest (CA) in association with subarachnoid hemorrhage (SAH) on short-term outcomes of mortality and discharge disposition. METHODS: This retrospective cohort study was conducted by analyzing de-identified data from the National (Nationwide) Inpatient Sample (NIS). The publicly available NIS database represents a 20% stratified sample of all discharges and is powered to estimate 95% of all inpatient care delivered across hospitals in the US. A total of 170,869 patients were identified as having been hospitalized due to nontraumatic SAH from 2008 to 2014. RESULTS: A total of 5415 patients (3.2%) were hospitalized with an admission diagnosis of CA in association with SAH. Independent risk factors for CA included a higher Charlson Comorbidity Index score, hospitalization in a small or nonteaching hospital, and a Medicaid or self-pay payor status. Compared with patients with SAH and not CA, patients with CA-SAH had a higher mean NIS Subarachnoid Severity Score (SSS) ± SD (1.67 ± 0.03 vs 1.13 ± 0.01, p < 0.0001) and a vastly higher mortality rate (82.1% vs 18.4%, p < 0.0001). In a multivariable model, age, NIS-SSS, and CA all remained significant independent predictors of mortality. Approximately 18% of patients with CA-SAH survived and were discharged to a rehabilitation facility or home with health services, outcomes that were most predicted by chronic disease processes and large teaching hospital status. CONCLUSIONS: In the largest study of its kind, CA at onset was found to complicate roughly 3% of spontaneous SAH cases and was associated with extremely high mortality. Despite this, survival can still be expected in approximately 18% of patients.

Direct Peritoneal Resuscitation (DPR) Improves Acute Physiology and Chronic Health Evaluation (APACHE) IV and Acute Physiology Score When Used in Damage Control Laparotomies: Prospective Cohort Study on 37 Patients.

INTRODUCTION: Using direct peritoneal resuscitation (DPR) as an adjunct when managing patients undergoing damage control laparotomy (DCL) shows promising results. We report our initial experience in utilizing DPR when managing patients who underwent DCL for emergent surgery at the index operation. MATERIALS AND METHODS: We prospectively collected data on 37 patients between August 2020 to October 2021 who underwent DCL with open abdomens after the index operation and utilized DPR. DPR was performed using peritoneal lavage with DIANEAL PD-2-D 2.5% Ca 3.5 mEq/L at a rate of 400ml/hour. Patients' physiological scores and clinical outcomes were evaluated. RESULTS: 86% required DCL and DPR due to septic abdomen/bowel ischemia. The median (interquartile range [IQR]) age was 62 years (53-70); 62% were male, and median (IQR) body mass index was 30.0kg/m2 (25.5-38.4). On DPR initiation, median (IQR) APACHE-IV score was 48 (33-64) and median (IQR) Acute Physiology Score (APS) was 31 (18-54). After initiation, median (IQR) APACHE-IV score and median (IQR) APS were 39 (21-62) and 19 (11-56), respectively, and both showed significant improvement in survivors (p<0.05). Median (IQR) DPR duration was four days (2-8) and primary abdominal closure was achieved in 30 patients (81%). There were eight mortalities (21.6%) within 30 days postoperatively, of which seven were within 3-24 days due to uncontrolled sepsis/multiple organ failure. The most frequent complication was surgical-site infection recorded in 12 patients (32%). Twenty-four patients (67%) were discharged home/transferred to a rehab center/nursing home. CONCLUSION: DPR application showed significant improvement of APACHE-IV score and APS in patients with peritonitis/septic abdomen.

Firearm Deaths are Increasing and Endemic in the USA: It is a Problem of Suicides and Not Homicides.

BACKGROUND: To analyze and report on the changes in epidemiology traumatic causes of death in the USA. METHODS: Data were extracted from the annual National Vital Statistics Reports (2008-2017) from Center for Disease Control and analyzed for trends during the time period given. Generalized additive model was applied to evaluate the significance of trend using R software. RESULTS: Firearm deaths (39,790) and firearm death rate (12.2/100,000) in 2017 were the highest reported, and this increasing trend was significant (p < 0.001) the last ten years. Deaths from motor vehicle crash (MVC) and firearm homicides did not change significantly during the same time period. Firearm deaths were lower than MVC deaths by 21% (8,197/39,790) in 2008, but after 10 years, the difference was only 1% (458/40,231). Years of life lost from firearms is now higher than MVC. Suicides by firearm in 2017 were the highest reported at 23,854/39,773 (60%). In 2017, suicides by firearm victims were predominantly white 20,328/23,562 (85%), men 20,362/23,562 (86%), and the largest group was between the ages of 55-64. CONCLUSIONS: Death from firearms in the USA is increasing and endemic. They were the highest ever reported in 2017 by the CDC. While deaths from MVC used to be the main cause of traumatic death in the USA, deaths from firearms now almost equal it. Calculated years of life lost from firearms is now more than from MVC. Most firearm deaths are not from homicides but are from suicides, and they are predominantly in white older males of the baby boomer generation (born 1946-1964).

Early Abdominal Wall Reconstruction with Biologic Mesh is Feasible after Catastrophic Abdominal Wall Disruption from Blunt Trauma.

INTRODUCTION: Traumatic abdominal wall hernias (TAWHs) after blunt trauma, while rare, are typically associated with severe injuries, particularly those involved with the seatbelt triad of abdominal wall disruption. The aim of this study is to present a case series of patients with TAWHs that were managed at an early stage post injury with a biological mesh. MATERIALS AND METHODS: Patients with TAWH undergoing complex abdominal wall reconstruction (CAWR) between 2017 and 2020 were identified from our institutional database. All patients underwent definitive reconstruction using advanced surgical techniques including a posterior component separation with biological mesh (STRATTICE™, Allergan, Inc., Dublin, Ireland) placed in a sublay fashion. RESULTS: Seven patients underwent definitive TAWH repair during their index admission: the median age was 56 years (range 20-77) and the median Injury Severity Score (ISS) was 34 (29-50). The most common mechanism of injury was motor vehicle crash (MVC) at 86%, while the most common intra-abdominal concomitant injury was small bowel. Traumatic hernia location was on the right side of the abdominal wall in three patients, left in three patients, and bilaterally in one patient. There were no hernia recurrences or deaths in this small cohort. CONCLUSION: Traumatic abdominal wall disruption can be safely reconstructed using advanced surgical techniques with a biological mesh during the acute phase or same index hospitalization.

Venous Thromboembolism in Geriatric Trauma Patients-Risk Factors and Associated Outcomes.

BACKGROUND: Venous thromboembolism (VTE) places elderly trauma patients at a high risk of morbidity. The purpose of this study was to determine the outcomes related to VTE in geriatric trauma patients, as well as to identify risk factors for the development of VTE in this population. We also assessed the impact of the type and timing of VTE prophylaxis, and the type of injuries, on development of VTE in geriatric trauma population. METHODS: We performed a 2-year retrospective review from American College of Surgeons-Trauma Quality Improvement Project (ACS-TQIP) databank from 2014 to 2016. A total of 354,272 patients aged 65 y or older who developed VTE after trauma were included in the study. RESULTS: Overall, 354,272 elderly trauma patients with complete records were identified from the year 2014 to 2016, and of this, 4290 (1.1%) patients developed in-hospital VTE. Male gender was more predominant in the VTE group (P < 0.001). Both the ICU length of stay and hospital length of stay (P < 0.001) were higher in the VTE group. Spine injury (P = 0.002), lower extremity injury (P < 0.001), age category 75-84 y (P < 0.001), age ≥85 y (P < 0.001), frailty (P < 0.001), severe traumatic brain injury (TBI) (GCS3-8) (P < 0.001), ventilator days (P < 0.001), and transfusion of plasma products in first 24 h of admission (P < 0.001) were independent predictors of developing VTE after trauma in the elderly. Higher injury severity score, TBI, and transfusion of packed red blood cells within 24 h were associated with longer time to initiate VTE prophylaxis. Time to initiate chemical deep vein thrombosis prophylaxis was significantly longer in those patients that developed VTE (3.73 ± 4.82 d), when compared with those patients without VTE ((1.81 ± 2.53 d) (P < 0.001). CONCLUSIONS: Our study demonstrates that ICU and hospital length of stay were higher in VTE group. Frailty, severe TBI, spine injury, lower extremity injury, longer duration of mechanical ventilation, and transfusion of plasma products in the first 24 h of hospital admission were independent predictors of developing VTE after trauma in elderly. Type and timing of VTE prophylaxis were not significant independent predictors of developing VTE after trauma, while higher injury severity score, TBI, and transfusion of packed red blood cells within 24 h were associated with longer time to initiate VTE prophylaxis. Future multi-institutional prospective studies are warranted to gather more evidence on this topic.

Falling Again? Falls in Geriatric Adults-Risk Factors and Outcomes Associated With Recidivism.

BACKGROUND: The elderly population is at increased risk of fall-related readmissions (FRRs). This study is aimed to identify the factors predictive of repeat falls and to analyze the associated outcomes. METHODS: We studied the Nationwide Readmission Database for the year 2010 and identified the patients (≥65 years) who were admitted after falls, and from that subset, further analyzed patients with ≥1 FRRs. Descriptive statistics were used to analyze continuous and categorical variables. Multivariable logistic regression was used to identify predictors of readmission in geriatric patients after controlling for covariates. RESULTS: A total of 358,581 initial fall-related admissions in geriatric adults were identified, and of these, 21,713 experienced ≥1 FRRs (6.06% risk of repeat fall-related admission). Females outnumbered males, and female gender was identified as an independent predictor of FRR (OR 1.10 95% CI 1.07-1.14 P = 0.000). The other independent predictors significantly associated with FRR were age (OR 1.007, 95% CI 1.005-1.009), depression (OR 1.25, 95% CI 1.21-1.30), drug abuse (OR 1.37, 95% CI 1.15-1.63), liver disease (OR 1.25, 95% CI 1.15-1.43, P < 0.001), psychosis (OR 1.16, 95% CI 1.09-1.23), valvular heart disease (OR 1.07, 95% CI 1.02-1.12), chronic pulmonary disease (OR 1.10, 95% CI 1.06-1.13), and number of chronic conditions (OR 1.022, 95% CI 1.016-1.29). Patients admitted emergently or urgently had higher odds of FRR (OR 1.44, 95% CI 1.36-1.52). Hospital demographic was a significant predictor of FRR, as hospitals with bed number >500 was associated with lower odds (OR 0.95, 95% CI 0.92-0.98, P < 0.001). Geriatric patients admitted at nonteaching hospitals and hospitals in large metro areas (population > 1 million) had higher odds of FRR (OR 1.10, 95% CI 1.03 - 1.16) and (OR 1.10, 95% C1 1.07-1.14), respectively. With respect to discharge disposition, patients in the FRR group were less likely to go home (5.9% versus 21.0%) or with home health care (12.6% versus 18.5%), but more likely to be discharged to skilled nursing or intermediate-care facilities (64.1% versus 54.9%) and short-term hospitals (2.8% versus 1.4%). The mortality rate was higher in the FRR group but was not statistically significant (OR 1.06, 95% CI 0.99-1.14). CONCLUSIONS: Given the high burden of fall-related injuries and FRRs to patients and the health care system, it is essential to identify those who are at risk. This study provides a comprehensive list of high-risk predictors as well as the impact on patient outcomes, and hence a chance to intervene for patients with FRRs.

Predictors of 30- and 90-Day Readmissions After Complex Abdominal Wall Reconstruction With Biological Mesh: A Longitudinal Study of 232 Patients.

BACKGROUND: Hospital readmissions are recognized as indicators of poor healthcare services which further increase patient morbidity. The aim of this study is to analyze predicting factors for the 30-day and 90-day readmissions after a complex abdominal wall reconstruction (CAWR). METHODS: A pooled analysis of the prospective study and retrospective database patients undergoing CAWR with acellular porcine dermis from 2012 to 2019 was carried out. Independent t test for continuous variables and Chi-square and Fischer's exact tests for categorical variables were used. A multivariable logistic regression model and linear regression analysis were used to analyze the independent predictors of 30-day and 90-day readmissions. RESULTS: A total of 232 patients underwent CAWR, and the readmission rate (RR) was 16.8% (n = 40). The 30-day and 90-day RR was 11.3% (n = 23) and 13.3% (n = 33), respectively. There were no statistical differences in age, frailty, and gender distribution between the two groups. There was no difference in ASA score, type of component separation, ventral hernia working group class, size of the biological mesh, placement of mesh, and intestinal resection rate. The Clavien-Dindo complications and mean comprehensive complication index (CCI) were higher in the readmission group as compared to no readmission group (p < 0.01). Readmitted patients had higher surgical site infections (p < 0.01) and wound necrosis (p = 0.01). Higher CCI, past or concomitant pelvic surgery, and the presence of enterocutaneous fistula were independent predictors of earlier days to readmission. CONCLUSION: Surgical site occurrences were associated with 30-day and 90-day readmissions after CAWR, while the presence of ascites and dialysis was associated with 90-day readmissions.

Mortality rates of severe traumatic brain injury patients: impact of direct versus nondirect transfers.

BACKGROUND: Direct transport of patients with severe traumatic brain injury (sTBI) to trauma centers (TCs) that can provide definitive care results in lower mortality rates. This study investigated the impact of direct versus nondirect transfers on the mortality rates of patients with sTBI. METHODS: Data on patients with TBI admitted between January 1, 2012, and December 31, 2013, to our Level I TC were obtained from the trauma registry. Data included patient age, sex, mechanism, and type of injury, comorbidities, Glasgow Coma Scale, Injury Severity scores, prehospital time, time to request and to transfer, time to initiation of multimodality monitoring and goal-directed therapy protocol, dwell time in the emergency department (EDT), and mortality. Data, reported in means ± standard deviation, were analyzed with the Student t-test and chi-square. Statistical significance was accepted at a P value < 0.05. RESULTS: sTBI direct transfer to TC versus transfer from non-TCs (NTC): Of the 1187 patients with TBI admitted to our TC, 768 (64.7%) were admitted directly from the scene, whereas 419 (35.3%) were admitted after secondary transfer. One hundred seventy-one (22.2%) of the direct transfers had Glasgow Coma Scale < 8 (sTBI) and 92 (21.9%) of the secondary transfers had sTBI. The transfer time: Time from scene to arrival to the EDT was significantly shorter for TC versus NTCs 43 ± 14 versus 77 ± 26 min, respectively (P < 0.05). EDT dwell time before transfer and time from injury to arrival to TC were 4.2 ± 2.1 and 6.2 ± 8.3 h, respectively. Mortality: There was a statistically significant lower mortality for patients with sTBI transferred directly from the scene to TCs as opposed to patients secondarily transferred, 33/171 (19.3%) versus 33/92 (35.8%), respectively (P < 0.05). CONCLUSIONS: To decrease TBI-related mortality, patients with suspected sTBI should be taken directly to a Level I or II TC unless they require life-saving stabilization at NTCs.

Is there a need for fresh frozen plasma and platelet transfusion in trauma patients receiving submassive transfusion?

Background: Blood transfusions have become a vital intervention in trauma care. There are limited data on the safety and effectiveness of submassive transfusion (SMT), that is defined as receiving less than 10 units packed red blood cells (PRBCs) in the first 24 hours. This study aimed to evaluate the efficacy and safety of fresh frozen plasma (FFP) and platelet transfusions in patients undergoing SMT. Methods: This is a retrospective cohort, reviewing the Trauma Quality Improvement Program database spanning 3 years (2016 to 2018). Adult patients aged 18 years and older who had received at least 1 unit of PRBC within 24 hours were included in the study. We used a multivariate regression model to analyze the cut-off units of combined resuscitation (CR) (which included PRBCs along with at least one unit of FFP and/or platelets) that leads to survival improvement. Patients were then stratified into two groups: those who received PRBC alone and those who received CR. Propensity score matching was performed in a 1:1 ratio. Results: The study included 85 234 patients. Based on the multivariate regression model, transfusion of more than 3 units of PRBC with at least 1 unit of FFP and/or platelets demonstrated improved mortality compared with PRBC alone. Among 66 319 patients requiring SMT and >3 units of PRBCs, 25 978 received PRBC alone, and 40 341 received CR. After propensity matching, 4215 patients were included in each group. Patients administered CR had a lower rate of complications (15% vs 26%), acute respiratory distress syndrome (3% vs 5%) and acute kidney injury (8% vs 11%). Rates of sepsis and venous thromboembolism were similar between the two groups. Multivariate regression analysis indicated that patients receiving 4 to 7 units of PRBC alone had significantly higher ORs for mortality than those receiving CR. Conclusion: Trauma patients requiring more than 3 units of PRBCs who received CR with FFP and platelets experienced improved survival and reduced complications. Level of evidence: Level III retrospective study.

Fragmentation of Care After Geriatric Trauma: A Nationwide Analysis of outcomes and Predictors.

The health care system for the elderly is fragmented, that is worsened when readmission occurs to different hospitals. There is limited investigation into the impact of fragmentation on geriatric trauma patient outcomes. The aim of this study was to compare the outcomes following readmissions after geriatric trauma. The Nationwide Readmissions Database (2016-2017) was queried for elderly trauma patients (aged ≥65 years) readmitted due to any cause. Patients were divided into 2 groups according to readmission: index vs non-index hospital. Outcomes were 30 and 180-day complications, mortality, and the number of subsequent readmissions. Multivariable logistic regression was performed to analyze the independent predictors of fragmentation of care. A total of 36,176 trauma patients were readmitted, of which 3856 elderly patients (aged ≥65 years) were readmitted: index hospital (3420; 89%) vs non-index hospital (436; 11%). Following 1:2 propensity matching, elderly with non-index hospital readmission had higher rates of death and MI within 180 days (P = .01 and .02, respectively). They had statistically higher 30 and 180-day pneumonia (P < .01), CHF (P < .01), arrhythmias (P < .01), MI (P < .01), sepsis (P < .01), and UTI (P < .01). On multivariable binary logistic regression analysis, pneumonia (OR 1.70, P = .03), congestive heart failure (CHF) (OR 1.80, P = .03), female gender (OR .72, P = .04), and severe Head and Neck trauma (AIS≥3) (OR 1.50, P < .01) on index admission were independent predictors of fragmentation of care. While the increase in time to readmission (OR 1.01, P < .01) was also associated independently with non-index hospital admission. Fragmented care after geriatric trauma could be associated with higher mortality and complications.

Predictors of mortality after craniotomy for geriatric traumatic brain injury.

BACKGROUND: With a sustained increase in the proportion of elderly trauma patients, geriatric traumatic brain injury (TBI) is a significant source of morbidity, mortality and resource utilization. The aim of our study was to assess the predictors of mortality in geriatric TBI patients who underwent craniotomy. METHODS: We performed a 4-year analysis of ACS-TQIP database (2016-2019) and included all geriatric trauma patients (≥65y) with isolated severe TBI who underwent craniotomy. We calculated 11- point modified frailty index (mFI) for patients. Our primary and secondary outcomes were mortality and unfavorable outcome, respectively. Multivariate regression analysis was performed to identify the predictors of outcomes. Patients with mFI ≥ 0.25 were defined as Frail, whereas patient with mFI of 0.08 or higher (<0.25) were identified as pre-frail; Non-frail patients were identified as mFI of <0.08. RESULTS: We analyzed data from 20,303 patients. The mortality rate was 17.7 % (3,587 patients). Having ≥ 2 concomitant types of intra-cranial hemorrhage (OR = 2.251, p < 0.001), and pre-hospital anticoagulant use (OR = 1.306, p < 0.001) increased the risks of mortality. Frailty, as a continuous variable, was not considered as a risk factor for mortality (p = 0.058) but after categorization, it was shown that compared to non-frails, patients with pre-frailty (OR = 1.946, p = 0.011) and frailty (OR = 1.786, p = 0.026) had increased risks of mortality. Higher mFI (OR = 4.841), age (OR = 1.034), ISS (OR = 1.052), having ≥ 2 concomitant types of intra-cranial hemorrhage (OR = 1.758), and use of anticoagulants (OR = 1.117) were significant risk factors for unfavorable outcomes (p < 0.001, for all). CONCLUSIONS: Having more than two types of intra-cranial hemorrhage and pre-hospital anticoagulant use were significant risk factors for mortality. The study's findings also suggest that frailty may not be a sufficient predictor of mortality after craniotomy in geriatric patients with TBI. However, frailty still affects the discharge disposition and favorable outcome. LEVEL OF EVIDENCE: Level III retrospective study.

Non-operative management of cirrhotic patients with acute calculous cholecystitis: How effective is it?

INTRODUCTION: Nonoperative management (NOM) of acute calculous cholecystitis (ACC) in patients with cirrhosis was proposed. We examined the outcomes of cirrhotic patients with ACC treated with cholecystectomy compared to NOM. METHODS: We analyzed the 2017-Nationwide Readmissions Database including cirrhotic patients with ACC. Patients were stratified: cholecystectomy, percutaneous cholecystostomy (PCT), and antibiotics only. PRIMARY OUTCOMES: complications, failure of NOM. SECONDARY OUTCOMES: mortality, length of stay (LOS), and charges. RESULTS: 3454 patients were identified. 1832 underwent cholecystectomy, 360 PCT, and 1262 were treated with antibiotics. PCT patients had higher mortality 16.9% vs. the antibiotics group 10.9% vs. cholecystectomy group 4.2%. PCT patients had longer LOS, but lower charges compared to the operative group. Failure of NOM was 28.2%. On regression, PCT was associated with mortality. CONCLUSION: ACC remains a morbid disease in cirrhosis patients. One in three failed NOM, had longer LOS, and higher mortality. Further studies are warranted to identify predictors of NOM failure. LEVEL OF EVIDENCE: Level III, prognostic.

Neuroendovascular Surgery Applications in Craniocervical Trauma.

Cerebrovascular injuries resulting from blunt or penetrating trauma to the head and neck often lead to local hemorrhage and stroke. These injuries present with a wide range of manifestations, including carotid or vertebral artery dissection, pseudoaneurysm, occlusion, transection, arteriovenous fistula, carotid-cavernous fistula, epistaxis, venous sinus thrombosis, and subdural hematoma. A selective review of the literature from 1989 to 2023 was conducted to explore various neuroendovascular surgical techniques for craniocervical trauma. A PubMed search was performed using these terms: endovascular, trauma, dissection, blunt cerebrovascular injury, pseudoaneurysm, occlusion, transection, vasospasm, carotid-cavernous fistula, arteriovenous fistula, epistaxis, cerebral venous sinus thrombosis, subdural hematoma, and middle meningeal artery embolization. An increasing array of neuroendovascular procedures are currently available to treat these traumatic injuries. Coils, liquid embolics (onyx or n-butyl cyanoacrylate), and polyvinyl alcohol particles can be used to embolize lesions, while stents, mechanical thrombectomy employing stent-retrievers or aspiration catheters, and balloon occlusion tests and super selective angiography offer additional treatment options based on the specific case. Neuroendovascular techniques prove valuable when surgical options are limited, although comparative data with surgical techniques in trauma cases is limited. Further research is needed to assess the efficacy and outcomes associated with these interventions.

Acute Respiratory Distress Syndrome in Patients with Subarachnoid Hemorrhage: Incidence, Predictive Factors, and Impact on Mortality.

INTRODUCTION: Acute respiratory distress syndrome (ARDS) is a known predictor of poor outcomes in critically ill patients. We sought to examine the role ARDS plays in outcomes in subarachnoid hemorrhage (SAH) patients. Prior studies investigating the incidence of ARDS in SAH patients did not control for SAH severity. Hence, we sought to determine the incidence ARDS in patients diagnosed with aneurysmal SAH and investigate the predisposing risk factors and impact upon outcomes. METHODS: A retrospective cohort study was conducted using the National Inpatient Sample (NIS) database for the years 2008 to 2014. Multivariate stepwise regression analysis was performed to identify the risk factors and outcome associated with developing ARDS in the setting of SAH. RESULTS: We identified 170,869 patients with non-traumatic subarachnoid hemorrhage, of whom 6962 were diagnosed with ARDS and of those 4829 required mechanical ventilation. ARDS more frequently developed in high grade SAH patients (1.97 ± 0.05 vs. 1.15 ± 0.01; p < 0.0001). Neurologic predictors of ARDS included cerebral edema (OR 1.892, CI 1.180-3.034, p = 0.0035) and medical predictors included cardiac arrest (OR 4.642, CI 2.273-9.482, p < 0.0001) and cardiogenic shock (OR 2.984, CI 1.157-7.696, p = 0.0239). ARDS was associated with significantly worse outcomes (15.5% vs. 52.9% discharged home, 63.0% vs. 40.8% discharged to rehabilitation facility and 21.5% vs. 6.3% in-hospital mortality). CONCLUSION: Patients with SAH who developed ARDS were less likely to be discharged home, more likely to need rehabilitation and had a significantly higher risk of mortality. The identification of risk factors contributing to ARDS is helpful for improving outcomes and resource utilization.

Early tracheostomy in patients undergoing mechanical thrombectomy for acute ischemic stroke.

PURPOSE: Respiratory failure following mechanical thrombectomy (MT) for acute ischemic stroke (AIS) is a known complication, and requirement of tracheostomy is associated with worse outcomes. Our objective is to evaluate characteristics associated with tracheostomy timing in AIS patients treated with MT. METHODS: The National Inpatient Sample was queried for adult patients treated with MT for AIS from 2016 to 2019. Baseline demographic characteristics, comorbidities, and inpatient outcomes were analyzed for associations in patients who received tracheostomy. Timing of early tracheostomy (ETR) was defined as placement before day 8 of hospital stay. RESULTS: Of 3505 AIS-MT patients who received tracheostomy, 915 (26.1%) underwent ETR. Patients who underwent ETR had shorter length of stay (LOS) (25.39 days vs 32.43 days, p < 0.001) and lower total hospital charges ($483,472.07 vs $612,362.86, p < 0.001). ETR did not confer a mortality benefit but was associated with less acute kidney injury (OR, 0.697; p = 0.013), pneumonia (OR, 0.449; p < 0.001), and sepsis (OR, 0.536; p = 0.002). CONCLUSION: An expected increase in complications and healthcare resource utilization is seen in AIS-MT patients receiving tracheostomy, likely reflecting the severity of patients' post-stroke neurologic injury. Among these high-risk patients, ETR was predictive of shorter LOS and fewer complications.

Firearms: the leading cause of years of potential life lost.

OBJECTIVES: Data from the Centers for Disease Control and Prevention (CDC) show that firearm deaths are increasing in the USA. The aims of this study were to determine the magnitude of potential years of life lost due to firearms and to examine the evolution of firearm deaths on the basis of sex, race, and geographical location within the USA. METHODS: Data was extracted (2009-2018) from the National Vital Statistics Reports from the CDC and the Web-based Injury Statistics Query and Reporting System database. Years of potential life lost was calculated by the CDC standard of subtracting the age at death from the standard year of 80, and then summing the individual years of potential life lost (YPLL) across each cause of death. RESULTS: The YPLL in 2017 and 2018 was higher for firearms than motor vehicle crashes (MVCs). In 2018, the YPLL for firearms was 1.42 million and 1.34 million for MVC. Males comprised the majority (85.4%) of the 38 929 firearm deaths. White males had the most YPLL due to suicide, with 4.95 million YPLL during the course of the 10-year period; black males had the most YPLL due to homicide with 3.2 million YPLL during the same time period. The largest number of suicides by firearms was in older white males. Firearm-related injury deaths were highest in the South, followed by the West, Midwest, and Northeast, respectively. CONCLUSION: Firearms are now the leading cause of YPLL in trauma. Firearm deaths have overtaken MVC as the mechanism for the main cause of potential years of life lost since 2017. Suicide in white males accounts for more YPLL than homicides. Deaths related to firearms are potentially preventable causes of death and prevention efforts should be redirected. LEVEL OF EVIDENCE: Level III-Descriptive Study.

Serial rotational thromboelastography (ROTEM) in mechanically ventilated patients with COVID-19 demonstrates hypercoagulopathy despite therapeutic heparinization.

Background: Clinical hypercoagulopathy in patients with COVID-19 has been anecdotally described, but there is lack of evidence due to the novelty of this disease. Our study reports the results of rotational thromboelastography (ROTEM) in relation to traditional laboratory coagulation tests and acute phase markers among a cohort of severely ill, mechanically ventilated patients with COVID-19. Methods: Patients with COVID-19 (N=21) with respiratory failure requiring mechanical ventilation were included in this prospective case series. ROTEM was serially obtained for all patients on three different days during their intensive care unit (ICU) stay and analyzed using repeated measures analysis. Demographic variables, symptoms at the time of presentation, ROTEM values, laboratory values for traditionally measured coagulation profiles, and acute phase reactants were analyzed, in addition to the use of anticoagulation and clinical hypercoagulopathic complications. Results: The average age of our cohort was 57.9 years old (SD=14.4) and 76.2% were male. The mortality rate was 14.3% (3 of 21). Two patients (12.5%) were identified to have new-onset deep vein thrombosis, two patients (12.5%) were found to have ≥3 episodes of central venous catheter thrombosis, and three patients (18.7%) had confirmed stroke. ROTEM demonstrated elevated EXTEM and INTEM clotting times, including elevated FIBTEM maximum clot firmness (MCFFIB). All patients treated with therapeutic anticoagulation still demonstrated hypercoagulopathy within the MCFFIB tests. Discussion: Repeated measure ROTEMs were able to detect hypercoagulopathy in ICU patients with COVID-19 despite therapeutic anticoagulation with heparin. Level of evidence: III.

Correlation of brain flow variables and metabolic crisis: a prospective study in patients with severe traumatic brain injury.

INTRODUCTION: Current treatment guidelines for patients with severe TBI (sTBI) are aimed at preventing secondary brain injury targeting specific endpoints of intracranial physiology to avoid the development of metabolic crisis. We sought to identify factors contributing to development of metabolic crisis in the setting of a Multi-modality Monitoring and Goal-Directed Therapy (MM&GDTP) approach to patients with severe TBI. METHODS: Prospective monitoring of sTBI patients was performed, with retrospective data analysis. MM&GDTP was targeted to intracranial pressure (ICP) ≤ 20 mmHg, cerebral perfusion pressure (CPP) ≥ 60 mmHg, brain tissue oxygen pressure (PbtO2) ≥ 20 mmHg, and cerebral oxygen extraction measured by bi-frontal Near infrared Spectroscopy (NIRS) > 55%. Brain flow abnormality was defined by one of the following combinations: CPP < 60 mmHg with NIRS < 55% (Type 1), CPP < 60 mmHg with PbtO2 < 20 mmHg (Type 2), or PbtO2 < 20 mmHg with NIRS < 55% (Type 3). Cerebral micro-dialysate was analyzed hourly for glucose, lactate, pyruvate, glutamate, glycerol, and lactate/pyruvate ratio (LPR). Statistical analysis was performed with student t-test, chi-square and Pearson's tests as applicable. RESULTS: A total of 109,474 consecutive minutes of recorded multimodality monitoring was available for analysis. There was a significant difference in the number of minutes of brain flow abnormalities between survivors and non-survivors: 0.8% (875) versus 7.49% (8,199), respectively (p < 0.05). The duration of Type 1-3 flow abnormality per patient was higher in non-survivors (5.7 ± 2.5 h) compared to survivors (0.7 ± 0.6 h) as well as the duration of metabolic crisis, namely, 5.2 ± 2.2 versus 0.6 ± 1.0 h per patient. The occurrence of severe metabolic crisis was associated with a Type 2 flow abnormality (CPP < 60 mmHg and PbtO2 < 20 mmHg), r = 0.97, p < 0.001, but not with Type 1 and 3. CONCLUSIONS: Metabolic crisis can occur despite a MM&GDTP approach aimed at optimizing cerebral blood flow. Severe metabolic crisis is associated to failure to maintain CPP and PbtO2 above 60 and 20 mmHg, respectively. The occurrence of severe metabolic crisis portends a poor prognosis in patients with sTBI.
