RESUMEN
INTRODUCTION: Organized trauma systems reduce morbidity and mortality after serious injury. Rapid transport to high-level trauma centers is ideal, but not always feasible. Thus, interhospital transfers are an important component of trauma systems. However, transferring a seriously injured patient carries the risk of worsening condition before reaching definitive care. In this study, we evaluated characteristics and outcomes of patients whose hemodynamic status worsened during the transfer process. METHODS: We conducted a retrospective cohort study using data from the Pennsylvania Trauma Outcomes Study database from 2011 to 2018. Patients were included if they had a heart rate ≤ 100 and systolic blood pressure ≥ 100 at presentation to the referring hospital and were transferred within 24 h. We defined hemodynamic deterioration (HDD) as admitting heart rate > 100 or systolic blood pressure < 100 at the receiving center. We compared demographics, mechanism of injury, injury severity, management, and outcomes between patients with and without HDD using descriptive statistics and multivariable regression analysis. RESULTS: Of 52,919 included patients, 5331 (10.1%) had HDD. HDD patients were more often moderately-severely injured (injury severity score 9-15; 40.4% versus 39.4%, P < 0.001) and injured via motor vehicle collision (23.2% versus 16.6%, P < 0.001) or gunshot wound (2.1% versus 1.3%, P < 0.001). HDD patients more often had extremity or torso injuries and after transfer were more likely to be transferred to the intensive care unit (35% versus 28.5%, P < 0.001), go directly to surgery (8.4% versus 5.9%, P < 0.001), or interventional radiology (0.8% versus 0.3%, P < 0.001). Overall mortality in the HDD group was 4.9% versus 2.1% in the group who remained stable. These results were confirmed using multivariable analysis. CONCLUSIONS: Interhospital transfers are essential in trauma, but one in 10 transferred patients deteriorated hemodynamically in that process. This high-risk component of the trauma system requires close attention to the important aspects of transfer such as patient selection, pretransfer management/stabilization, and communication between facilities.

Nontrauma service (NTS) admissions are an increasing problem as ground-level falls in elderly patients become more common. The admission and evaluation of trauma patients to nontrauma services in trauma centers seeking American College of Surgeons (ACS) verification, must follow the ACS mandates for performance improvement requiring some method of evaluating this population when admitted to services other than trauma, orthopedics, and neurosurgery. The purpose of this study and performance improvement project was to improve our process for the definition and evaluation of trauma patients who were being admitted to nontrauma services. We designed an algorithm to evaluate appropriateness of NTS admission and evaluated outcomes for NTS admissions utilizing that algorithm.We created a scoring algorithm and evaluated appropriateness of NTS admission over 2 years in a community-teaching ACS Level II trauma center. We reviewed trauma registry data using χ and Fisher exact tests to determine differences in outcome for NTS versus trauma service (TS) admissions.From December 2014 to December 2016, NTS admission rate fell from maximum of 28% to 4% stabilizing between 8% and 10%. Mortality and overall complication rate between NTS and TS were similar (p = .40 and .66, respectively), but length of stay was lower for TS admissions (p < .0001).A scoring system of algorithm can be used to determine appropriateness of NTS admissions, and validity of the tool can be confirmed using registry-based outcome data for TS versus NTS admissions.

BACKGROUND: Although several society guidelines exist regarding emergency department thoracotomy (EDT), there is a lack of data upon which to base guidance for multiple gunshot wound (GSW) patients whose injuries include a cranial GSW. We hypothesized that survival in these patients would be exceedingly low. METHODS: We used Pennsylvania Trauma Outcomes Study data, 2002 to 2021, and included EDTs for GSWs. We defined EDT by International Classification of Diseases codes for thoracotomy or procedures requiring one, with a location flagged as emergency department. We defined head injuries as any head Abbreviated Injury Scale (AIS) score of ≥1 and severe head injuries as head AIS score of ≥4. Head injuries were "isolated" if all other body regions have an AIS score of <2. Descriptive statistics were performed. Discharge functional status was measured in five domains. RESULTS: Over 20 years in Pennsylvania, 3,546 EDTs were performed; 2,771 (78.1%) were for penetrating injuries. Most penetrating EDTs (2,003 [72.3%]) had suffered GSWs. Survival among patients with isolated head wounds (n = 25) was 0%. Survival was 5.3% for the non-head injured (n = 94 of 1,787). In patients with combined head and other injuries, survival was driven by the severity of the head wound-0% (0 of 81) with a severe head injury ( p = 0.035 vs. no severe head injury) and 4.5% (5 of 110) with a nonsevere head injury. Of the five head-injured survivors, two were fully dependent for transfer mobility, and three were partially or fully dependent for locomotion. Of 211 patients with a cranial injury who expired, 2 (0.9%) went on to organ donation. CONCLUSION: Although there is clearly no role for EDT in patients with isolated head GSWs, EDT may be considered in patients with combined injuries, as most of these patients have minor head injuries and survival is not different from the non-head injured. However, if a severe head injury is clinically apparent, even in the presence of other body cavity injuries, EDT should not be pursued. LEVEL OF EVIDENCE: Therapeutic/Care Management; Level IV.

ABSTRACT: The first Fallen Surgeons Military Educational Symposium was convened in conjunction with the the American Association for the Surgery of Trauma (AAST) 23 meeting, under the guidance of the AAST Military Liaison Committee. The daylong session included a 1.5-hour segment on military medical ethics in combat and its unique challenges. Medical ethical issues arise frequently within the military across a range of varied circumstances, from the day-to-day operations of stateside forces to the complexities of deployed troops in theaters of conflict. Given the scope of these circumstances, preparation and advanced planning are the key to addressing and resolving the ethical issues that occur. The goal of this session was to present illustrative cases, not to prescribe solutions, and to make the attendees aware of some of the challenges they may encounter when deployed.

INTRODUCTION: Solid metals may create a variety of injuries. White phosphorous (WP) is a metal that causes both caustic and thermal injuries. Because of its broad use in munitions and smoke screens during conflicts and wars, all military clinicians should be competent at WP injury identification and acute therapy, as well as long-term consequence recognition. MATERIALS AND METHODS: English-language manuscripts addressing WP injuries were curated from PubMed and Medline from inception to January 31, 2024. Data regarding WP injury identification, management, and sequelae were abstracted to construct a Scale for the Assessment of Narrative Review Articles guideline-consistent narrative review. RESULTS: White phosphorous appears to be ubiquitous in military conflicts. White phosphorous creates a characteristic wound appearance accompanied by smoke, a garlic aroma, and spontaneous combustion on contact with air. Decontamination and burning prevention or cessation are key and may rely on aqueous irrigation and submersion or immersion in substances that prevent air contact. Topical cooling is a key aspect of preventing spontaneous ignition as well. Disposal of all contaminated clothing and gear is essential to prevent additional injury, especially to rescuers. Long-term sequelae relate to phosphorous absorption and may lead to death. Chronic or repeated exposure may induce jaw osteonecrosis. Tactical Combat Casualty Care recommendations do not currently address WP injury management. CONCLUSIONS: Education and management regarding WP acute injury and late sequelae is essential for acute battlefield and definitive facility care. Resource-replete and resource-limited settings may use related approaches for acute management and ignition prevention. Current burn wound management recommendations should incorporate specific WP management principles and actions for military clinicians at every level of skill and environment.
RESUMEN
Objectives: Percutaneously placed small-bore (14 Fr) catheters and pleural lavage have emerged independently as innovative approaches to hemothorax management. This report describes techniques for combining percutaneous thoracostomy with pleural lavage and presents results from a performance improvement series of patients managed with percutaneous thoracostomy with immediate lavage. Methods: This was a prospective performance improvement series of patients treated at a level 1 trauma center with percutaneous thoracostomy and immediate lavage between April 2021 and May 2023. Results: Percutaneous thoracostomy with immediate lavage was used to treat nine hemodynamically normal patients with acute hemothorax. Injuries included both blunt and penetrating mechanisms. 56% of patients presented immediately after injury, and 44% presented in a delayed fashion ranging from 2 to 26 days after injury. Median length of stay was 6 days (IQR 6, 9). Seven patients were discharged home in stable condition, one was discharged to an acute rehabilitation facility, and one was discharged to a skilled nursing facility. Conclusions: Percutaneous thoracostomy with pleural lavage is clinically feasible and effective and warrants further evaluation with a multicenter clinical trial. Level of evidence: Therapeutic/care management, level V.
RESUMEN
Management of infected wounds related to calciphylaxis poses a significant clinical challenge with high morbidity and mortality. Given no definitive management guidelines exist specific to nonuremic calciphylaxis, multiple modalities including sodium thiosulfate, antibiotics, hyperbaric oxygen therapy, and surgical debridement with wound care must be considered. When occurring over a large surface area, standard daily dressing changes are especially labor intensive, inefficient, and ineffective. Negative pressure wound therapy with instillation and dwell time offers broad wound coverage with ongoing therapeutic benefit. We present the case of a previously healthy 19-year-old woman who was transferred for tertiary level care of extensive nonuremic calciphylaxis wounds of the bilateral lower extremities complicated by angioinvasive coinfection with fungus and mold that was managed with a multidisciplinary approach of intensive medical management, aggressive surgical debridement, and negative pressure wound therapy with instillation of hypochlorous acid solution. Ultimately, she achieved full granulation and wound coverage with skin grafting. Large area, infected wounds related to nonuremic calciphylaxis can be successfully managed with multidisciplinary medical management, aggressive surgical debridement, and negative pressure wound therapy that can instill and dwell hypochlorous acid solution.

Introduction: Hemorrhagic pericardial effusion (HPE) is a rare but life-threatening diagnosis that may occur after thoracic trauma. Previous reports have concentrated on delayed HPE in those who did not require initial surgical intervention for their traumatic injuries. In this report, we identify and characterize the phenomenon of HPE after emergent thoracic surgery for trauma. Methods: This is a retrospective review of patients who required emergent thoracic surgery for trauma at a level 1 trauma center from 2017 to 2021. Using the institutional trauma database, demographics, injury characteristics, and outcomes were compared between patients with HPE and those without HPE after thoracic surgery for trauma. Results: Ninety-one patients were identified who underwent emergent thoracic surgery for trauma. Most were young men who sustained a penetrating thoracic injury. Seven patients (7.7%) went on to develop HPE. Patients who developed HPE were younger (18 vs. 32 years, p=0.034), required bilateral anterolateral thoracotomy (85% vs. 7%, p<0.001), and were more likely to have pulmonary injuries (100% vs. 52.4%, p<0.001). Five patients with HPE survived to hospital discharge. The two patients with HPE who died were both coagulopathic and had HPE diagnosed within 4 days of injury. The median time to HPE diagnosis in survivors was 24 days with four of five HPE survivors on therapeutic anticoagulation at the time of diagnosis. Conclusions: HPE may occur after emergent thoracic surgery for trauma. Those at highest risk of HPE include younger patients with bilateral thoracotomy incisions and pulmonary injuries. Early HPE, clinical signs of tamponade, and/or coagulopathy in patients with HPE portend a worse prognosis. Surgeons and trauma team members caring for patients after emergent thoracic exploration for trauma should be aware of this potentially devastating complication and should consider postoperative echocardiography in high-risk patients.
RESUMEN
BACKGROUND: Hemorrhagic shock requires timely administration of blood products and resuscitative adjuncts through multiple access sites. Intraosseous (IO) devices offer an alternative to intravenous (IV) access as recommended by the massive hemorrhage, A-airway, R-respiratory, C-circulation, and H-hypothermia (MARCH) algorithm of Tactical Combat Casualty Care (TCCC). However, venous injuries proximal to the site of IO access may complicate resuscitative attempts. Sternal IO access represents an alternative pioneered by military personnel. However, its effectiveness in patients with shock is supported by limited evidence. We conducted a pilot study of two sternal-IO devices to investigate the efficacy of sternal-IO access in civilian trauma care. METHODS: A retrospective review (October 2020 to June 2021) involving injured patients receiving either a TALON® or a FAST1® sternal-IO device was performed at a large urban quaternary academic medical center. Baseline demographics, injury characteristics, vascular access sites, blood products and medications administered, and outcomes were analyzed. The primary outcome was a successful sternal-IO attempt. RESULTS: Nine males with gunshot wounds transported to the hospital by police were included in this study. Eight patients were pulseless on arrival, and one became pulseless shortly thereafter. Seven (78%) sternal-IO placements were successful, including six TALON devices and one of the three FAST1 devices, as FAST1 placement required attention to Operator positioning following resuscitative thoracotomy. Three patients achieved return of spontaneous circulation, two proceeded to the operating room, but none survived to discharge. CONCLUSIONS: Sternal-IO access was successful in nearly 80% of attempts. The indications for sternal-IO placement among civilians require further evaluation compared with IV and extremity IO access.

Humanitarian crises create opportunities for both in-person and remote aid. Durable, complex, and team-based care may leverage a telemedicine approach for comprehensive support within a conflict zone. Barriers and enablers are detailed, as is the need for mission expansion due to initial program success. Adapting a telemedicine program initially designed for critical care during the severe acute respiratory syndrome coronavirus 2 pandemic offers a solution to data transfer and data analysis issues. Staffing efforts and grouped elements of patient care detail the kinds of remote aid that are achievable. A multiprofessional team-based approach (clinical, administrative, nongovernmental organization, government) can provide comprehensive consultation addressing surgical planning, critical care management, infection and infection control management, and patient transfer for complex care. Operational and network security create parallel concerns relevant to avoid geolocation and network intrusion during consultation. Deliberate approaches to address cultural differences that influence relational dynamics are also essential for mission success.
RESUMEN
ABSTRACT: Austerity in surgical care may manifest by limited equipment/supplies, deficient infrastructure (power, water), rationing/triage requirements, or the unavailability of specialty surgical or medical expertise. Some settings in which surgeons may experience austerity include the following: military deployed operations (domestic and foreign), humanitarian surgical missions, care in rural or remote settings, mass-casualty events, natural disasters, and/or care in low- and some middle-income countries. Expanded competencies beyond those required in routine surgical practice can optimize the quality of surgical care in such settings. The purpose of this expert panel review is to introduce those competencies.

BACKGROUND: Trauma center mortality rates are benchmarked to expected rates of death based on patient and injury characteristics. The expected mortality rate is recalculated from pooled outcomes across a trauma system each year, obscuring system-level change across years. We hypothesized that risk-adjusted mortality would decrease over time within a state-wide trauma system. METHODS: We identified adult trauma patients presenting to Level I and II Pennsylvania trauma centers, 1999-2018, using the Pennsylvania Trauma Outcomes Study. Multivariable logistic regression generated risk-adjusted models for mortality in all patients, and in key subgroups: penetrating torso injury, blunt multisystem trauma, and patients presenting in shock. RESULTS: Of 162,646 included patients, 123,518 (76.1%) were white and 108,936 (67.0%) were male. The median age was 49 (interquartile range [IQR] 29-70), median injury severity score was 16 (IQR 10-24), and 87.5% of injuries were blunt. Overall, 9.9% of patients died, and compared to 1999, no year had significantly higher adjusted odds of mortality. Overall mortality was significantly lower in 2007-2009 and 2011-2018. Of patients with blunt, multisystem injuries, 17.7% died, and adjusted mortality improved over time. Mortality rates were 24.9% for penetrating torso injury, and 56.9% for shock, with no significant change. Mortality improved for patients with ISS < 25, but not for the most severely injured. CONCLUSIONS: Over 20 years, Pennsylvania trauma centers demonstrated improved risk-adjusted mortality rates overall, but improvement remains lacking in high-risk groups despite numerous innovations and practice changes in this time period. Identifying change over time can help guide focus to these critical gaps.

Babesiosis is an emerging infection most commonly acquired from a tick bite. We describe three hospitalized patients with fever attributable to babesiosis after a splenectomy. Splenectomy was done because of splenic enlargement due to unsuspected babesia infection in one patient and because of splenic perforation due to babesiosis in a second patient. The third patient underwent splenectomy for trauma and acquired babesiosis postoperatively from a blood transfusion. Our cases demonstrate the need to be vigilant for babesiosis in patients undergoing splenectomy.

BACKGROUND: Links between trauma center volumes and outcomes have been inconsistent in previous studies. This study examines the role of institutional trauma volume parameters in geriatric motor vehicle collision (MVC) survival. METHODS: The New York Statewide Planning and Research Cooperative Systems database was analyzed for all trauma admissions to state-designated Level I and II trauma centers from 1996 to 2003. For each center, the volume of patients was calculated in each of the following four categories: Young adult (age, 17-64 years) MVC and non-MVC, and geriatric (65 years and older) MVC and non-MVC. Logistic regression analysis was used to predict patient survival to hospital discharge based on the four volume parameters of the center at which they were treated, age, gender, ICISS, year of admission, and type of center. RESULTS: Five thousand three hundred sixty-five geriatric MVC victims were admitted to Level I (n = 3,541) or II (n = 1,824) centers in New York State excluding New York City. Four thousand eight hundred ninety-eight (91%) patients were discharged alive. Volume of geriatric MVC at the center at which the patient was treated was an independent significant predictor of survival (odds ratio, 32.6; 95% confidence interval, 2.8-377.0; p = 0.005) as were younger age, female gender, increased ICISS, and later year of discharge. Young adult non-MVC volume was an independent significant predictor of nonsurvival of geriatric patients (odds ratio, 0.8; 95% confidence interval, 0.64-0.99; p = 0.042). Type of center was unrelated to outcome. CONCLUSIONS: There may be a risk-adjusted survival advantage for geriatric MVC patients treated at trauma centers with relatively higher volumes of geriatric MVC trauma and lower volumes of young adult non-MVC trauma. These results support consideration of age in trauma center transfer criteria.

BACKGROUND: The SARS-CoV-2 pandemic has caused respiratory failure in many patients. With no effective treatment or vaccine, prolonged mechanical ventilation is common in survivors. Timing and performance of tracheostomy, for both patient and surgical team safety, remains a question. Here within, we report our experience with percutaneous dilatational tracheostomy with modification to minimize aerosolization. METHODS: A modified percutaneous dilatational tracheostomy technique is described. The technique was performed on 10 patients in the surgical intensive care unit. RESULTS: Ten patients underwent percutaneous dilatational tracheostomy. There were 7 males, and the average age for the group was 60.8 years. The average number of ventilator days before the operation was 26.3. All procedures were successful, and no patient had any procedure-related complications. CONCLUSIONS: The procedure described was successful in our patient population. We believe that this approach is safe for patients with coronavirus disease 2019 and limits aerosolization during the operation. LEVEL OF EVIDENCE: Level IV, case series.

OBJECTIVE: To develop a clinical practice guideline for red blood cell transfusion in adult trauma and critical care. DESIGN: Meetings, teleconferences and electronic-based communication to achieve grading of the published evidence, discussion and consensus among the entire committee members. METHODS: This practice management guideline was developed by a joint taskforce of EAST (Eastern Association for Surgery of Trauma) and the American College of Critical Care Medicine (ACCM) of the Society of Critical Care Medicine (SCCM). We performed a comprehensive literature review of the topic and graded the evidence using scientific assessment methods employed by the Canadian and U.S. Preventive Task Force (Grading of Evidence, Class I, II, III; Grading of Recommendations, Level I, II, III). A list of guideline recommendations was compiled by the members of the guidelines committees for the two societies. Following an extensive review process by external reviewers, the final guideline manuscript was reviewed and approved by the EAST Board of Directors, the Board of Regents of the ACCM and the Council of SCCM. RESULTS: Key recommendations are listed by category, including (A) Indications for RBC transfusion in the general critically ill patient; (B) RBC transfusion in sepsis; (C) RBC transfusion in patients at risk for or with acute lung injury and acute respiratory distress syndrome; (D) RBC transfusion in patients with neurologic injury and diseases; (E) RBC transfusion risks; (F) Alternatives to RBC transfusion; and (G) Strategies to reduce RBC transfusion. CONCLUSIONS: Evidence-based recommendations regarding the use of RBC transfusion in adult trauma and critical care will provide important information to critical care practitioners.

Lithium-ion (Li-ion) batteries have been powering portable electronic equipment since the mid-1990s. Today, they are ubiquitous in portable electronics, with more than four billion manufactured each year. However, Li-ion batteries are also associated with a spectrum of injuries related to the type of device as well as the person using the device. These injuries range from cutaneous injuries due to flame burns and explosions to corrosion injuries from ingestion. This article describes how the composition of Li-ion batteries can cause injury, the types and extent of Li-ion battery-related injuries, and suggests strategies for prevention.

BACKGROUND: American College of Surgeons (ACS) verification is believed to provide benefits for trauma patients, but is associated with direct costs. STUDY DESIGN: We performed a 1-year retrospective review of the National Trauma Data Bank (NTDB) for 2012. Patients were separated into 3 age groups; Pediatric (PEDS), 0 to 14 years; adult, 15 to 65 years; and elderly (ELD), older than 65 years. We analyzed 2 injury severity cohorts, Injury Severity Score (ISS) 9 to 74 (ALL) and ISS 25 to 74 (MAJ). Multiple logistic regression to determine significance of ACS verification on mortality and major complications, controlling for age, ISS, shock, Glasgow Coma Scale, sex, age, comorbidities, and mechanism. Patients were excluded with an ISS <8 or equal to 75, dead on arrival, emergency department transfers, and burns. RESULTS: There were 392,997 patients: 262,644 in ACS centers and 130,353 in non-ACS centers. Distribution was: PEDS 3.8%, adults 64.5%, ELD 31.7%. For ALL adults, no differences were observed for primary outcome in ACS vs non-ACS centers (p = 0.128 and 0.061, for mortality and complications, respectively). For ALL PEDS and ELD, complications were more likely in non-ACS centers: (p = 0.003, odds ratio [OR] 2.61 [95% CI 1.36 to 5.0], and p < 0.0001, OR 3.17 [95% CI 2.21 to 4.56]). For MAJ trauma, death was more likely in adults in ACS vs non-ACS centers (p = 0.013, OR 0.82 [95% CI 0.71 to 0.96]). Complications for MAJ trauma were more likely in all age groups in non-ACS centers (adult: p = 0.028, OR 1.48 [95% CI 1.04 to 2.1]; ELD: p < 0.0001, OR 2.49 [95% CI 1.7 to 3.7]; PEDS: p < 0.0001, OR 4.29 [95% CI 2.13 to 8.69]). Length of stay was increased for all patients with complications (p < 0.0001). CONCLUSIONS: Measurable benefits in complications were observed in all age groups with MAJ trauma and in PEDS and ELD for ALL injury severity in ACS vs non-ACS trauma centers.
