0.05% Chlorhexidine Gluconate Irrigation in Trauma/Emergency General Surgical Laparotomy Wounds Closure: A Pilot Study.

INTRODUCTION: Patients who undergo exploratory laparotomy (EL) in an emergent setting are at higher risk for surgical site infections (SSIs) compared to the elective setting. Packaged Food and Drug Administration-approved 0.05% chlorhexidine gluconate (CHG) irrigation solution reduces SSI rates in nonemergency settings. We hypothesize that the use of 0.05% CHG irrigation solution prior to closure of emergent EL incisions will be associated with lower rates of superficial SSI and allows for increased rates of primary skin closure. METHODS: A retrospective observational study of all emergent EL whose subcutaneous tissue were irrigated with 0.05% CHG solution to achieve primary wound closure from March 2021 to June 2022 were performed. Patients with active soft-tissue infection of the abdominal wall were excluded. Our primary outcome is rate of primary skin closure following laparotomy. Descriptive statistics, including t-test and chi-square test, were used to compare groups as appropriate. A P value <0.05 was statistically significant. RESULTS: Sixty-six patients with a median age of 51 y (18-92 y) underwent emergent EL. Primary wound closure is achieved in 98.5% of patients (65/66). Bedside removal of some staples and conversion to wet-to-dry packing changes was required in 27.3% of patients (18/66). We found that most of these were due to fat necrosis. We report no cases of fascial dehiscence. CONCLUSIONS: In patients undergoing EL, intraoperative irrigation of the subcutaneous tissue with 0.05% CHG solution is a viable option for primary skin closure. Further studies are needed to prospectively evaluate our findings.

Early Tracheostomy in Older Trauma Patient Is Associated With Comparable Outcomes to Younger Cohort.

INTRODUCTION: Early tracheostomy (ET) is associated with a lower incidence of pneumonia (PNA) and mechanical ventilation duration (MVD) in hospitalized patients with trauma. The purpose of this study is to determine if ET also benefits older adults compared to the younger cohort. METHODS: Adult hospitalized trauma patients who received a tracheostomy as registered in The American College of Surgeons Trauma Quality Improvement Program from 2013 to 2019 were analyzed. Patients with tracheostomy prior to admission were excluded. Patients were stratified into 2 cohorts consisting of those aged ≥65 and those aged <65. These cohorts were analyzed separately to compare the outcomes of ET (<5 d; ET) versus late tracheostomy (LT) (≥5 d; LT). The primary outcome was MVD. Secondary outcomes were in-hospital mortality, hospital length of stay (HLOS), and PNA. Univariate and multivariate analyses were performed with significance defined as P value < 0.05. RESULTS: In patients aged <65, ET was performed within a median of 2.3 d (interquartile range, 0.47-3.8) after intubation and a median of 9.9 d (interquartile range, 7.5-13) in the LT group. The ET group's Injury Severity Score was significantly lower with fewer comorbidities. There were no differences in injury severity or comorbidities when comparing the groups. ET was associated with lower MVD (d), PNA, and HLOS on univariate and multivariate analyses in both age cohorts, although the degree of benefit was higher in the less than 65 y cohort [ET versus LT MVD: 5.08 (4.78-5.37), P < 0.001; PNA: 1.45 (1.36-1.54), P < 0.001; HLOS: 5.48 (4.93-6.04), P < 0.001]. Mortality did not differ based on time to tracheostomy. CONCLUSIONS: ET is associated with lower MVD, PNA, and HLOS in hospitalized patients with trauma regardless of age. Age should not factor into timing for tracheostomy placement.

Thromboelastography Parameters do not Discriminate for Thrombotic Events in Hospitalized Patients With COVID-19.

BACKGROUND: Coronavirus disease 2019 (COVID-19) is associated with a prothrombotic state; leading to multiple sequelae. We sought to detect whether thromboelastography (TEG) parameters would be able to detect thromboembolic events in patients hospitalized with COVID-19. METHODS: We performed a retrospective multicenter case-control study of the Collaborative Research to Understand the Sequelae of Harm in COVID (CRUSH COVID) registry of 8 tertiary care level hospitals in the United States (US). This registry contains adult patients with COVID-19 hospitalized between March 2020 and September 2020. RESULTS: A total of 277 hospitalized COVID-19 patients were analyzed to determine whether conventional coagulation TEG parameters were associated with venous thromboembolic (VTE) and thrombotic events during hospitalization. A clotting index (CI) >3 was present in 45.8% of the population, consistent with a hypercoagulable state. Eighty-three percent of the patients had clot lysis at 30 min (LY30) = 0, consistent with fibrinolysis shutdown, with a median of 0.1%. We did not find TEG parameters (LY30 area under the receiver operating characteristic [ROC] curve [AUC] = 0.55, 95% CI: 0.44-0.65, P value = .32; alpha angle [α] AUC = 0.58, 95% CI: 0.47-0.69, P value = .17; K time AUC = 0.58, 95% CI: 0.46-0.69, P value = .67; maximum amplitude (MA) AUC = 0.54, 95% CI: 0.44-0.64, P value = .47; reaction time [R time] AUC = 0.53, 95% CI: 0.42-0.65, P value = .70) to be a good discriminator for VTE. We also did not find TEG parameters (LY30 AUC = 0.51, 95% CI: 0.42-0.60, P value = .84; R time AUC = 0.57, 95%CI: 0.48-0.67, P value .07; α AUC = 0.59, 95%CI: 0.51-0.68, P value = .02; K time AUC = 0.62, 95% CI: 0.53-0.70, P value = .07; MA AUC = 0.65, 95% CI: 0.57-0.74, P value < .01) to be a good discriminator for thrombotic events. CONCLUSIONS: In this retrospective multicenter cohort study, TEG in COVID-19 hospitalized patients may indicate a hypercoagulable state, however, its use in detecting VTE or thrombotic events is limited in this population.

In Vitro Analysis of Platelet Adhesion, Aggregation, and Surface GP1bα Expression in Stored Refrigerated Whole Blood: A Pilot Study.

BACKGROUND: Warm, fresh whole blood (WB) has been used by the US military to treat casualties in Iraq and Afghanistan. Based on data in that setting, cold-stored WB has been used to treat hemorrhagic shock and severe bleeding in civilian trauma patients in the United States. In an exploratory study, we performed serial measurements of WB's composition and platelet function during cold storage. Our hypothesis was that in vitro platelet adhesion and aggregation would decrease over time. METHODS: WB samples were analyzed on storage days 5, 12, and 19. Hemoglobin, platelet count, blood gas parameters (pH, Po2, Pco2, and Spo2), and lactate were measured at each timepoint. Platelet adhesion and aggregation under high shear were assessed with a platelet function analyzer. Platelet aggregation under low shear was assessed using a lumi-aggregometer. Platelet activation was assessed by measuring dense granule release in response to high-dose thrombin. Platelet GP1bα levels were measured with flow cytometry, as a surrogate for adhesive capacity. Results at the 3 study timepoints were compared using repeat measures analysis of variance and post hoc Tukey tests. RESULTS: Measurable platelet count decreased from a mean of (163 + 53) × 109 platelets per liter at timepoint 1 to (107 + 32) × 109 at timepoint 3 (P = .02). Mean closure time on the platelet function analyzer (PFA)-100 adenosine diphosphate (ADP)/collagen test increased from 208.7 + 91.5 seconds at timepoint 1 to 390.0 + 148.3 at timepoint 3 (P = .04). Mean peak granule release in response to thrombin decreased significantly from 0.7 + 0.3 nmol at timepoint 1 to 0.4 + 0.3 at timepoint 3 (P = .05). Mean GP1bα surface expression decreased from 232,552.8 + 32,887.0 relative fluorescence units at timepoint 1 to 95,133.3 + 20,759.2 at timepoint 3 (P < .001). CONCLUSIONS: Our study demonstrated significant decreases in measurable platelet count, platelet adhesion, and aggregation under high shear, platelet activation, and surface GP1bα expression between cold-storage days 5 and 19. Further studies are needed to understand the significance of our findings and to what degree in vivo platelet function recovers after WB transfusion.

A Comparative Survey Study of In-Person Versus Virtual Trauma Peer Review Meetings.

BACKGROUND: The American College of Surgeons Committee on Trauma mandates regular peer review meetings for verified trauma centers. The COVID-19 pandemic forced in-person meetings to transition to an online platform. OBJECTIVE: The objective of this study was to assess the opinions of participants regarding the benefits and negative aspects of the virtual peer review process. We hypothesize that physicians and nurses would prefer a virtual meeting format. METHODS: An anonymous online survey of members of the American Association for the Surgery of Trauma and the Society of Trauma Nurses was distributed in May and June of 2021. Demographic data and Likert scale-based responses were collected using the Research Electronic Data Capture platform. RESULTS: Invitations were sent to 1,726 physicians and 2,912 nurses. In total, 137 (8%) physicians and 141 (5%) nurses completed the survey. Both groups felt that either platform was effective in addressing opportunities for improvement in care. Physicians disagreed with the statement that anonymous online voting improved their ability to more accurately address opportunities for improvement. In total, 108 (79%) physicians and 100 (71%) nurses preferred a hybrid meeting. Only 18 (13%) physicians and 23 (16%) nurses wanted virtual meetings, whereas only 29 (21%) physicians and 36 (26%) nurses wanted in-person meetings going forward. CONCLUSIONS: Virtual and in-person trauma peer review meetings are equally effective in terms of case discussion and identifying opportunities for improvement in care. Given that most people preferred a hybrid meeting, future studies evaluating how best to incorporate and implement this format are needed.

Age Does Not Predict Failure to Rescue Following Resuscitative Thoracotomy in Penetrating Trauma.

BACKGROUND: The limitations of resuscitative thoracotomy (RT) after penetrating trauma have been well documented, but there is a paucity of data on the effect age has on mortality. This begs the question as to the utility of RT in an aging patient population. We investigate the significance of age as a predictor for failure to rescue after RT in penetrating trauma. OBJECTIVE: We sought to identify whether chronologic age has a measurable effect on rates of failure to rescue after RT. METHODS: We performed a retrospective cohort analysis using the Trauma Quality Improvement Program from 2011 to 2015 including all pulseless patients undergoing RT after penetrating injury. Our primary outcome was failure to rescue defined as death in the emergency department after RT. Multivariate analyses were performed to identify the relationship between age and morality controlling for injury severity. RESULTS: One thousand one hundred twelve RTs were performed during the study period with an overall failure to rescue rate of 61.8% (n = 687) within the emergency department and an in-hospital mortality rate of 96.9%, which is in line with national data. On univariate analysis, there was no significant association between age and mortality (p = 0.44). On multivariate analysis examining the interaction between age and mortality adjusting for injury severity, we found that chronologic age was not an independent predictor of death after RT. CONCLUSIONS: Age does not appear to be an independent predictor of failure to rescue after RT in penetrating trauma and should not be a sole determinant in procedural decision making.

Evaluation and management of intraabdominal hypertension.

PURPOSE OF REVIEW: The purpose of this review is to provide an overview of the pathophysiology of intraabdominal hypertension/compartment syndrome and to review the recent advances in the areas of evaluation and management of this disorder. RECENT FINDINGS: The incidence of intraabdominal hypertension (IAH) in intensive care units is as high as 45%, an incidence much higher than initially suspected. Despite decompressive laparotomy as a treatment, mortality in patients who developed abdominal compartment syndrome (ACS) requiring this procedure is as high as 50%. Some patients may be treated by fewer invasive methods, such as paracentesis, thereby avoiding the morbidity of laparotomy. Protective lung ventilation is key to managing the pulmonary sequalae of ACS. Point-of-care ultrasound can be used as an adjunctive decision-making tool. SUMMARY: IAH is common in critically ill patients and portends a high mortality rate. Prevention and early recognition are key in minimizing adverse events.

Interhospital Transfer of Critically Ill Patients Because of Coronavirus Disease 19-Related Respiratory Failure.

OBJECTIVE: Interfacility transfer of patients with coronavirus disease 2019-related acute respiratory failure is high risk because of the severity of respiratory failure and potential for crew exposure. This article describes a hospital-based transport team's experience with interfacility transport of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-positive patients. METHODS: A retrospective study of transports for respiratory failure caused by SARS-CoV-2 was performed. All transports were performed by a single critical care transport team. The team was already trained in advanced mechanical ventilation, blood gas interpretation, and management of shock. Guidance from the Centers for Disease Control and Prevention was followed regarding the use of personal protective equipment. RESULTS: Twenty patients were enrolled. The average patient age was 47 years (standard deviation [SD] = 12 years). The average Acute Physiology and Chronic Health Evaluation and Sequential Organ Failure Assessment scores were 10 (SD = 4) and 24 (SD = 7), respectively. The average transport distance and time were 18 miles (SD = 9 miles) and 25 minutes (SD = 11 minutes), respectively. Nineteen patients were intubated, 9 of whom required advanced ventilation. Two patients were transported prone. One patient experienced unintentional extubation upon transfer from the stretcher to the destination facility bed. The patient was reintubated without event. No crewmembers contracted SARS-CoV-2 infection. CONCLUSION: Interfacility transfer of severely ill SARS-CoV-2-positive patients is safe and feasible.

Fatal Wounding Pattern and Causes of Potentially Preventable Death Following the Pulse Night Club Shooting Event.

BACKGROUND: Mortality following shooting is related to time to provision of initial and definitive care. An understanding of the wounding pattern, opportunities for rescue, and incidence of possibly preventable death is needed to achieve the goal of zero preventable deaths following trauma. METHODS: A retrospective study of autopsy reports for all victims involved in the Pulse Nightclub Shooting was performed. The site of injury, probable site of fatal injury, and presence of potentially survivable injury (defined as survival if prehospital care is provided within 10 minutes and trauma center care within 60 minutes of injury) was determined independently by each author. Wounds were considered fatal if they involved penetration of the heart, injury to any non-extremity major blood vessel, or bihemispheric, mid-brain, or brainstem injury. RESULTS: There were an average of 6.9 wounds per patient. Ninety percent had a gunshot to an extremity, 78% to the chest, 47% to the abdomen/pelvis, and 39% to the head. Sixteen patients (32%) had potentially survivable wounds, 9 (56%) of whom had torso injuries. Four patients had extremity injuries, 2 involved femoral vessels and 2 involved the axilla. No patients had documented tourniquets or wound packing prior to arrival to the hospital. One patient had an isolated C6 injury and 2 victims had unihemispheric gunshots to the head. CONCLUSIONS: A comprehensive strategy starting with civilian providers to provide care at the point of wounding along with a coordinated public safety approach to rapidly evacuate the wounded may increase survival in future events.

The utility of point-of-care ultrasound in targeted automobile ramming mass casualty (TARMAC) attacks.

As terrorist actors revise their tactics to outmaneuver increasing counter-terrorism security measures, a recent trend toward less-sophisticated attack methods has emerged. Most notable of these "low tech" trends are the Targeted Automobile Ramming MAss Casualty (TARMAC) attacks. Between 2014 and November 2017, 18 TARMAC attacks were reported worldwide, resulting in 181 deaths and 679 injuries. TARMAC attack-related injuries are unique compared to accidental pedestrian trauma and other causes of mass casualty incidents (MCI), and therefore they require special consideration. No other intentional mass casualty scenario is the result of a blunt, non-penetrating trauma mechanism. Direct vehicle impact results in high-power injuries including blunt trauma to the central nervous system (CNS), and thoracoabdominal organs with crush injuries if the victims are run over. Adopting new strategies and using existing technology to diagnose and treat MCI victims with these injury patterns will save lives and limit morbidity. Point-of-care ultrasound (POCUS) is one such technology, and its efficacy during MCI response is receiving an increasing amount of attention. Ultrasound machines are becoming increasingly available to emergency care providers and can be critically important during a MCI when access to other imaging modalities is limited by patient volume. By taking ultrasound diagnostic techniques validated for the detection of life-threatening cardiothoracic and abdominal injuries in individuals and applying them in a TARMAC mass casualty situation, physicians can improve triage and allocate resources more effectively. Here, we revisit the high-yield applications of POCUS as a means of enhanced prehospital and hospital-based triage, improved resource utilization, and identify their potential effectiveness during a TARMAC incident.

Platelet transfusion does not improve outcomes in patients with brain injury on antiplatelet therapy.

INTRODUCTION: Platelet dysfunction following traumatic brain injury (TBI) is associated with worse outcomes. The efficacy of platelet transfusion to reverse antiplatelet medication (APM) remains unknown. Thrombelastography platelet mapping (TEG-PM) assesses platelet function. We hypothesize that platelet transfusion can reverse the effects of APM but does not improve outcomes following TBI. METHODS: An observational study at six US trauma centres was performed. Adult patients on APM with CT evident TBI after blunt injury were enrolled. Demographics, brain CT and TEG-PM results before/after platelet transfusion, length of stay (LOS), and injury severity score (ISS) were abstracted. RESULTS: Sixty six patients were enrolled (89% aspirin, 50% clopidogrel, 23% dual APM) with 23 patients undergoing platelet transfusion. Transfused patients had significantly higher ISS and admission CT scores. Platelet transfusion significantly reduced platelet inhibition due to aspirin (76.0 ± 30.2% to 52.7 ± 31.5%, p < 0.01), but had a non-significant impact on clopidogrel-associated inhibition (p = 0.07). Platelet transfusion was associated with longer length of stay (7.8 vs. 3.5 days, p < 0.01), but there were no differences in mortality. CONCLUSION: Platelet transfusion significantly decreases platelet inhibition due to aspirin but is not associated with change in outcomes in patients on APM following TBI.

Alcohol level and injury severity: is the floppy patient myth true?

BACKGROUND: The impact of inebriation on severity of injury is unclear. The few studies to date on this topic are limited to a particular mechanism of injury (MOI), injury pattern, or blood alcohol level (BAL). Therefore, we sought to determine the impact of BAL on injury pattern and severity across all MOI. We hypothesize that there is no relationship between BAL and injury severity when controlling for MOI. MATERIALS AND METHODS: After institutional review board approval, a retrospective study was performed at an adult trauma center from January 1, 2012-December 31, 2012. All MOI were included. Injury severity was assessed using the injury severity score (ISS). Chi square and analysis of variance were used to examine the relationship between BAL, injury pattern, and ISS within each MOI. Multivariate regression analysis examined the BAL-ISS association adjusting for MOI, gender, and age. RESULTS: Of 1397 patients, the mean age was 44 ± 19, ISS was 7.5 ± 6.8, BAL was 93 ± 130 mg/dL, and 70% were male. Rib fracture (P = 0.002) and hemothorax and/or pneumothorax (P = 0.0009) were negatively associated with BAL, whereas concussion and soft tissue injury had a positive association with BAL (P < 0.0001). An increasing BAL had a negative correlation with ISS after fall from standing (P < 0.001), whereas bicycle collisions had a positive association (P = 0.027). Across all MOI, there was no significant association between BAL and ISS. CONCLUSIONS: BAL is associated with ISS, in specific MOI; however, across all MOI, there was no significant association between BAL and ISS. Inebriated patients should be triaged with the same clinical index of suspicion for injury as sober patients.

Timing of death after traumatic injury--a contemporary assessment of the temporal distribution of death.

BACKGROUND: The trimodal distribution of traumatic death was first described by Trunkey in 1983, which demonstrated that most deaths occur in the first 24 h. We postulate that since 1983, the time-to-death histogram described has shifted. METHODS: A retrospective analysis identifying timing of death was conducted on the National Trauma Data Bank (version 7.2) from 2002 to 2006. Early death was defined as death within 24 h of admission. International Classification of Diseases ninth edition codes with greater than 20% early deaths were called "high-risk codes". Bivariate analyses were conducted to assess the association between demographics, injury factors, and death. Pearson's χ(2) test was used to compare timing of death by region of injury. Multivariate logistic regression was conducted to show the effect of region of injury on death while controlling for demographic factors and injury type. RESULTS: The cohort includes 898,982 patients. The study population was predominantly male (66%) and Caucasian (62%). Mean age and injury severity score were 45 ± 20.3 and 11 ± 10, respectively. Overall mortality rate was 5% with 56% dying early. Head/neck, thorax, and abdomen/pelvis injuries were more prevalent in overall deaths (35%, 22%, and 11%, respectively). Thorax and abdomen/pelvis injuries predicted early death (odds ratio 2.03 and 1.39, respectively). CONCLUSIONS: The prevalence of early death has decreased since 1983, but the majority of deaths still occur within 24 h of injury. Ample opportunity remains to impact mortality in the first 24 h after injury.

Trauma team size and task performance in adult trauma resuscitations.

BACKGROUND: The initial evaluation of a trauma patient involves multiple personnel from various disciplines. Whereas this approach can expedite care, an increasing number of personnel can also create chaos and hinder efficiency. We sought to determine the optimal number of persons associated with an expedient primary survey. METHODS: Audio and/or video recordings of all consecutive adult trauma evaluations at a level 1 trauma center were reviewed for a 1-month period. A 20-task checklist was developed based on Advanced Trauma Life Support principles. The number of practitioners present (TeamN) and tasks completed at 2 and 5 min (Task2, Task5) were recorded. The association between TeamN, demographics, presence of attending surgeon, and team leader engagement and Task2/Task5 was measured the using chi square test and Spearman correlation. A multivariate regression model was developed. RESULTS: A total of 170 cases were reviewed, 44 of which were top-tier activations. Average TeamN was 6 ± 2 persons. Task2 and Task5 were significantly positively correlated with TeamN (r = 0.34, P < 0.0001; r = 0.22, P = 0.004, respectively) and leader engagement (r = 0.27, P < 0.01; r = 0.16, P < 0.05, respectively). There was a significant positive correlation between TeamN and Task2 and Task5. Only TeamN had a significant, independent association with Task2 and Task5 (P = 0.005). We did not find a size that was negatively associated with task completion. Only assessment of breath sounds was negatively associated with increasing team size. CONCLUSIONS: TeamN is significantly associated with efficiency of trauma evaluation. Studies evaluating reasons for this and the effect of maximal team size are needed to determine optimal trauma team staffing.

Comparison of Mortality and Costs at Trauma and Nontrauma Centers for Minor and Moderately Severe Injuries in California.

STUDY OBJECTIVE: We examine differences in inpatient mortality and hospitalization costs at trauma and nontrauma centers for injuries of minor and moderate severity. METHODS: Inpatient data sets from the California Office of Statewide Health Planning and Development were analyzed for 2009 to 2011. The study population included patients younger than 85 years and admitted to general, acute care hospitals with a primary diagnosis of a minor or moderate injury. Minor injuries were defined as having a New Injury Severity Score less than 5 and moderate injuries as having a score of 5 to 15. Multivariate logistic regression and generalized linear model with log-link and γ distribution were used to estimate differences in adjusted inpatient mortality and costs. RESULTS: A total of 126,103 admissions with minor or moderate injury were included in the study population. The unadjusted mortality rate was 6.4 per 1,000 admissions (95% confidence interval [CI] 5.9 to 6.8). There was no significant difference found in mortality between trauma and nontrauma centers in unadjusted (odds ratio 1.2; 95% CI 0.97 to 1.48) or adjusted models (odds ratio 1.1; 95% CI 0.79 to 1.57). The average cost of a hospitalization was $13,465 (95% CI $12,733 to $14,198) and, after adjustment, was 33.1% higher at trauma centers compared with nontrauma centers (95% CI 16.9% to 51.6%). CONCLUSION: For patients admitted to hospitals for minor and moderate injuries, hospitalization costs in this study population were higher at trauma centers than nontrauma centers, after adjustments for patient clinical-, demographic-, and hospital-level characteristics. Mortality was a rare event in the study population and did not significantly differ between trauma and nontrauma centers.

Critical Care for the Patient With Multiple Trauma.

Trauma remains the leading cause of death worldwide and the leading cause of death in those less than 44 years old in the United States. Admission to a verified trauma center has been shown to decrease mortality following a major injury. This decrease in mortality has been a direct result of improvements in the initial evaluation and resuscitation from injury as well as continued advances in critical care. As such, it is vital that intensive care practitioners be familiar with various types of injuries and their associated treatment strategies as well as their potential complications in order to minimize the morbidity and mortality frequently seen in this patient population.

Critical Violent Injury in the United States: A Review and Call to Action.

OBJECTIVE: This review provides an overview of what is known about violent injury requiring critical care, including child physical abuse, homicide, youth violence, intimate partner violence, self-directed injury, firearm-related injury, and elder physical abuse. DATA SOURCES: We searched PubMed, Scopus, Ovid Evidence-Based Medicine Reviews, and the National Guideline Clearinghouse. We also included surveillance data from the Centers for Disease Control and Prevention and National Trauma Data Bank. STUDY SELECTION: Search criteria limited to articles in English and reports of humans, utilizing the following search terms: intentional violence, intentional harm, violence, crime victims, domestic violence, child abuse, elder abuse, geriatric abuse, nonaccidental injury, nonaccidental trauma, and intentional injury in combination with trauma centers, critical care, or emergency medicine. Additionally, we included relevant articles discovered during review of the articles identified through this search. DATA EXTRACTION: Two hundred one abstracts were reviewed for relevance, and 168 abstracts were selected and divided into eight categories (child physical abuse, homicide, youth violence, intimate partner violence, self-directed injury, firearm-related injury, and elder physical abuse) for complete review by pairs of authors. In our final review, we included 155 articles (139 articles selected from our search strategy, 16 additional highly relevant articles, many published after we conducted our formal search). DATA SYNTHESIS: A minority of articles (7%) provided information specific to violent injury requiring critical care. Given what is known about violent injury in general, the burden of critical violent injury is likely substantial, yet little is known about violent injury requiring critical care. CONCLUSIONS: Significant gaps in knowledge exist and must be addressed by meaningful, sustained tracking and study of the epidemiology, clinical care, outcomes, and costs of critical violent injury. Research must aim for not only information but also action, including effective interventions to prevent and mitigate the consequences of critical violent injury.

Successful management of severe flail chest via early operative intervention.

A review on the role of open reduction and internal fixation of flail chest injuries is presented. A 37-year-old woman involved in a motorcycle crash sustained comminuted rib fractures on her right 3rd through 12th ribs. On postinjury day 2, the patient's fifth through ninth ribs were surgically reduced and plated. Later that same day, the patient was successfully weaned from mechanical ventilation and experienced a rapid improvement in incentive spirometry volumes. Further studies are needed to definitively determine the benefits of rib plating versus conventional treatment. Through our case, we are able to demonstrate successful management of pain and chest wall instability associated with flail chest through the use of rib plating.

Contemporary Management of Patients with Multiple Rib Fractures: What You Need to Know.

ABSTRACT: 10% of all injured patients and 55% of patients with blunt chest trauma experience rib fractures. The incidence of death due to rib fractures is related to the number of fractured ribs, severity of fractured ribs, and patient age and co-morbid conditions. Death due to rib fracture is mostly caused by pneumonia due to inability to expectorate and take deep breaths. Over the last 25-30 years, there has been renewed interest in surgical stabilization of rib fractures, known colloquially as "rib plating". This review will present what you need to know in regards to triage decisions on whether or not to admit a patient to the hospital, the location to which they should be admitted, criteria and evidentiary support for SSRF, timing to SSRF, and operative technique. The review also addresses the cost-effectiveness of this operation and stresses non-operative treatment modalities that should be implemented prior to operation.Article TypeReview, Level III.

Comparison of Law Enforcement Officer versus Emergency Medical Services Placed Tourniquets.

INTRODUCTION: Tourniquet (TQ) use for hemorrhage control is a core skill for many law enforcement officers (LEO) and all emergency medical services (EMS) providers. However, LEO TQ training is not as intensive as EMS. Overuse of TQ can result in over triage. We hypothesize that LEO are more liberal than EMS with TQ placement. METHODS: A seven-year retrospective, single center study of adult patients who had a TQ placed in the field was conducted. Data were stratified by provider who placed the TQ. Patient demographics, body location where the TQ was placed, hospital location where the TQ was removed, incidence of recurrent bleeding and need for operative control of bleeding, and name of injured vessel were recorded. Data were analyzed using student t-test and Chi-square tests. RESULTS: 192 patients had 197 TQ placed (LEO 77 (40%) and EMS 120 (63%). Most TQ were placed on the thigh. There was no difference in body mass index but the EMS cohort had a higher injury severity score (9.4 v 6.5, p = 0.03) and extremity abbreviated injury severity score (2.4 v 1.9, p = 0.007). LEO placed TQ were more commonly removed in the trauma bay (83% v 73%, p = 0.03). EMS placed TQ were more likely to require operative control of bleeding (23% v 6%, p = 0.003). There were no complications related to TQ use in either arm. CONCLUSIONS: LEO are more likely than EMS to place tourniquets without injury to a named vessel or the presence of severe bleeding. LEO need better training to determine when a TQ is needed. EMS should be allowed to remove TQ if appropriate. Studies on the impact of over triage based on TQ use are needed.
