ABSTRACT
Little is known about the association between epidural catheters (EC) and venous thromboembolism (VTE) in trauma. We sought to study this association and hypothesized that trauma patients with EC were more likely to develop VTE. Using the Pennsylvania Trauma Outcomes Study (PTOS) registry, we identified all adult trauma patients (age ≥ 18) admitted for at least 2 days between 1/2013 and 12/2017. Baseline characteristics and outcome variables were compared between patients who underwent EC placement and those who did not. The primary outcome was development of VTE. 147,721 patients met inclusion criteria; 2247 (1.5%) developed a VTE. Patients were mostly white (85%), male (56%), with blunt trauma (94%). 776 (0.5%) had an EC placed. Patients who underwent EC placement were more likely to develop a VTE (2.8% vs. 1.5%, p = 0.003). After adjusting for covariates, patients with EC were 1.6 times more likely to develop VTE (95% CI 1.1-2.5). The overall rate of VTE was low and associated with the use of EC. Future work should focus on determining the underlying mechanisms.

BACKGROUND: Rib fractures are a common consequence of traumatic injury and can result in significant debilitation. Rib fixation offers fracture stabilization, resulting in improved outcomes and decreased pulmonary complications, especially in high-risk groups such as those with flail segments. However, commercial rib fixation has only recently become clinically prevalent, and we hypothesize that significant variability exists in its utilization based on injury pattern and trauma center. METHODS: The Pennsylvania Trauma System Foundation database was queried for all multiple rib fracture patients occurring statewide in 2016 and 2017. Demographics including the presence of flail and the occurrence of rib fixation was abstracted. Outcomes were compared between the fixation group and all other rib fracture patients. Deidentified treating trauma center was used to elicit center-level disparities. RESULTS: During the study period, there were 12,910 patients with multiple rib fractures, of which 135 had flail segments. 57 patients underwent rib fixation, and 10 of which had a flail segment. Compared with the nonoperative cohort, those who underwent rib fixation were younger (52.5 versus 61.5, P = 0.0009), similar in gender (68% versus 62% male, P = 0.373), and race (80% versus 86% White, P = 0.239). The rib fixation group had higher Injury Severity Scores (19.4 versus 15.4 P = 0.0011). The timing of rib fixation was most frequent within 1 wk of injury but extended out through 3 wk; the occurrence of pulmonary complications had a similar distribution. The frequency of rib fixation rates within trauma centers was not associated with rib fracture patient volume, and 37.1% of multiple rib fracture patients were cared for at centers that did not perform rib fixation. CONCLUSIONS: Rib fixation is infrequently used at trauma centers in Pennsylvania. It is used more frequently in nonflail injuries, and its use may be associated with the occurrence of pulmonary complications. Significant center-level variation exists in rib fixation rates among multiple fractured patients. A significant number of patients are cared for at centers that do not perform rib fixation. Further research is needed to illicit better-defined indications for operative fixation, and opportunities exist to further the penetrance of this practice to all trauma centers.

PURPOSE: There are currently no evidence-based indications for surgical stabilization of rib fractures (SSRF) in patients without flail chest. The purpose of this survey was to identify patients for whom there is relative equipoise (operative vs. non-operative) in order to assist in designing a randomized clinical trial. METHODS: Members of the Chest Wall Injury Society were sent an online survey, in which 18 patient scenarios were presented. The baseline patient had ≥ three displaced, contiguous fractures and had no other contraindications for surgery. This default scenario was then varied based upon patient age, degree of traumatic brain injury (TBI), fracture series location, and number of abnormal pulmonary physiologic variables (oxygen requirement, respiratory rate, incentive spirometry ability, cough, and numeric pain score). RESULTS: Thirty respondents provided a total of 540 answers. Overall, the majority of responses were in favor of SSRF (n = 413, 84.1%). Furthermore, the vast majority of responses indicated that some degree of pulmonary compromise was necessary to recommend SSRF (n = 44, 90.4%), with ≥ two abnormal parameters being the most common threshold (n = 156, 31.8%). Decision to recommend SSRF varied significantly by number of abnormal clinical variables, age, and degree of TBI, but not by fracture series location. Patients aged 85 years old and those with moderate TBI were the least likely to be recommended for SSRF, regardless of abnormal pulmonary physiologic variables. The most appropriate cutoff for equipoise appeared to be a patient aged 21-79 years old, with no or mild TBI, ≥ two abnormal pulmonary parameters, and regardless of fracture location (44.8% consensus for SSRF). CONCLUSIONS: SSRF was recommended for most patients with non-flail, displaced rib fractures. However, this recommendation was contingent upon patient age, degree of TBI, and pulmonary clinical status. Results of this survey may be used to inform inclusion criteria for a future randomized, clinical trial.

Necrotising soft tissue infection (NSTI) presents unique challenges in diagnosis and management. The key to a successful outcome is a high index of suspicion in appropriate clinical settings. Type II NSTI tends to occur on an extremity in younger, healthier patients with a history of known trauma, and to be monomicrobial. Type I NSTI tends to occur on the trunk of older, less healthy patients without an obvious history of trauma, and tends to be polymicrobial. Other, rarer types exist as well. The pathophysiology of both types involves superantigen acticivty, as well as a number of microbial byproducts which collectively decrease the viscosity of pus, facilitating its spread along deep tissue planes and ultimately causing diffuse deep thrombosis and aggressive systemic sepsis. The most important physical finding is tenderness to palpation beyond the area of redness, and the lack of crepitus should not be seen as a reassuring sign. Suspected cases should undergo early surgical exploration for diagnosis, which may be performed at bedside through a small incision. Most imaging techniques are not sufficiently specific to warrant a delay in surgical exploration. The Laboratory Risk Indicator for Necrotising Fasciitis (LRINEC) shows promise as a tool for excluding suspected cases. Successful outcomes in cases of NSTI require early and aggressive serial debridement and a multidisciplinary critical care approach.

OBJECTIVES: Predicting injury patterns of patients based only on mechanism of injury is difficult and is well described in the literature. Characteristics of patients on-scene immediately following injury(ies) may lead to predicting injury patterns. Although reported frequently, the significance of victim ambulation after a motor vehicle crash is poorly understood. It was hypothesized that ambulation at the scene is not predictive of injury severity following a motor vehicle crash (MVC). METHODS: A prospective, cohort study of 117 consecutive injured patients who were ambulatory after MVCs were enrolled. Paramedics in a large urban Emergency Medical Services (EMS) system were mandated to document "ambulatory" or "nonambulatory" for motor vehicle collisions in order to complete their prehospital electronic medical records. This assured accuracy and completeness in the data collection. All charts were abstracted for trauma-induced injury and imaging results. RESULTS: A total of 608 (10.9%) persons were ambulatory at the scene, of which 284 had an injury pattern documented in the prehospital or emergency department record. The average age was 35.9 (SD = 16.8) years, and 158 (55.6%) were male. A total of 707 injuries were identified in the 284 patients who had sustained injuries. CONCLUSIONS: Ambulation after motor vehicle collisions appears to be only infrequently associated with major injuries, although this population still may present with significant injuries. A larger, prospective study is warranted.

INTRODUCTION: Tissue transplantation is an important adjunct to modern medical care and is used daily to save or improve patient lives. Tissue allografts include bone, tendon, corneas, heart valves and others. Increasing utilization may lead to tissue shortages, and tissue procurement organizations continue to explore ways to expand the cadaveric donor pool. Currently more than half of all deaths occur outside the acute care setting. HYPOTHESIS: Many who suffer prehospital deaths might be eligible for non-organ tissue donation. METHODS: A retrospective review of electronic prehospital medical records was conducted from May 1, 2008 through December 31, 2009. All prehospital deaths were included irrespective of cause. Once identified, additional medical history was obtained from prehospital, inpatient, and emergency department records. Age, medical history, and time of death were compared to exclusion criteria for four tissue procurement organizations (MTF, LifeNet, LifeCell, EyeBank). After analysis, percentages of eligible donors were calculated. RESULTS: Over 50,000 prehospital records were reviewed; 432 subjects died in the field and were eligible for analysis. Ages ranged from four to 103 years of age; the average was 68.3 (SD = 20.1) years. After exclusion for age, medical conditions, and time of death, 185 unique patients (42.8%) were eligible for donation to at least one of the four tissue procurement organizations (range 11.6%-34.3%). CONCLUSIONS: After prehospital death, many individuals may be eligible for tissue donation. These findings suggest that future prospective studies exploring tissue donation after prehospital death are indicated. These studies should aim to clarify eligibility criteria, create protocols and infrastructure, and explore the ethical implications of expanding tissue donation to include this population.

OBJECTIVE: Helicopter emergency medical services (HEMS) are widely used in regional trauma care and present unique challenges in the patient handoff process. In particular, the practice of patient handoff on the landing zone versus the trauma bay does not exist in ground emergency medical services. We hypothesized that patients handed off on the landing zone versus the trauma bay would have different patient characteristics and outcomes. METHODS: A retrospective review identified 305 HEMS trauma patients received at our level 1 trauma center over a 3-year period. Patients were sorted on the basis of the handoff location, (landing zone vs. trauma bay) and assessed for predictors of injury severity including the Revised Trauma Score, the Injury Severity Score, the Trauma and Injury Severity Score, and other outcomes, primarily mortality. RESULTS: Of the 305 patients, 235 (77%) were handed off in the bay, and 70 (23%) were not. Regarding the characteristics of patients who were handed off in the bay, they were more likely to have hypotension (100% vs. 73%), have a lower O(2) saturation level (97.9 vs. 99.4), and a lower Glasgow Coma Scale at the scene (10.9 vs. 13.9.). When controlling for injury severity, the odds of survival for patients who were handed off in the bay were 11.06 times the odds for patients who were not handed off in the bay. CONCLUSION: In this limited study, we found that HEMS did identify the sickest patients and brought them to the trauma bay. Despite their greater injury severity, the patients handed off in the bay fared better than those handed off on the landing zone.

Emergency surgery in patients with significant comorbidities benefits from a structured approach to preoperative evaluation, intra-operative intervention, and postoperative management. Providing goal concordant care is ideal using shared decision-making. When operation cannot achieve the patient's goal, non-operative therapy including Comfort Care is appropriate. When surgical therapy is offered, preoperative physiology-improving interventions are far fewer than in other phases. Reevaluation of clinical care progress helps define trajectory and inform goals of care. Palliative Care Medicine may be critical in supporting loved ones during a patient's critical illness. Outcome evaluation defines successful strategies and outline opportunities for improvement.

BACKGROUND: Treatment for multiple rib fractures includes surgical stabilization of rib fractures (SSRF) or nonoperative management (NOM). Meta-analyses have demonstrated that SSRF results in faster recovery and lower long-term complication rates versus NOM. Our study evaluated postoperative outcomes for multiple rib fracture patients following SSRF versus NOM in a real-world, all-comer study design. METHODS: Multiple rib fracture patients with inpatient admissions in the PREMIER hospital database from October 1, 2015, to September 30, 2020, were identified. Outcomes included discharge disposition, and 3- and 12-month lung-related readmissions. Demographics, comorbidities, concurrent injuries at index, Abbreviated Injury Scale and Injury Severity Scores, and provider characteristics were determined for all patients. Patients were excluded from the cohort if they had a thorax Abbreviated Injury Scale score of <2 (low severity patient) or a Glasgow Coma Scale score of ≤8 (extreme high severity patient). Stratum matching between SSRF and NOM patients was performed using fine stratification and weighting so that all patient data were kept in the final analysis. Outcomes were analyzed using generalized linear models with quasinormal distribution and logit links. RESULTS: A total of 203,450 patients were included, of which 200,580 were treated with NOM and 2,870 with SSRF. Compared to NOM, patients with SSRF had higher rates of home discharge (62% SSRF vs. 58% NOM) and lower rates of lung-related readmissions (3 months, 3.1% SSRF vs. 4.0% NOM; 12 months, 6.2% SSRF vs. 7.6% NOM). The odds ratio (OR) for home or home health discharge in patients with SSRF versus NOM was 1.166 (95% confidence interval [CI], 1.073-1.266; p = 0.0002). Similarly, ORs for lung-related readmission at 3- and 12-month were statistically lower in the patients treated with SSRF versus NOM (OR [3 months], 0.764 [95% CI, 0.606-0.963]; p = 0.0227 and OR [12 months], 0.799 [95% CI, 0.657-0.971]; p = 0.0245). CONCLUSION: Surgical stabilization of rib fractures results in greater odds of home discharge and lower rates of lung-related readmissions compared with NOM at 12 months of follow-up. LEVEL OF EVIDENCE: Therapeutic/Care Management; Level III.

BACKGROUND: Chest wall injury in older adults is a significant cause of morbidity and mortality. Optimal nonsurgical management strategies for these patients have not been fully defined regarding level of care, incentive spirometry (IS), noninvasive positive pressure ventilation (NIPPV), and the use of ketamine, epidural, and other locoregional approaches to analgesia. METHODS: Relevant questions regarding older patients with significant chest wall injury with patient population(s), intervention(s), comparison(s), and appropriate selected outcomes were chosen. These focused on intensive care unit (ICU) admission, IS, NIPPV, and analgesia including ketamine, epidural analgesia, and locoregional nerve blocks. A systematic literature search and review were conducted, our data were analyzed qualitatively and quantitatively, and the quality of evidence was assessed per the Grading of Recommendations Assessment, Development, and Evaluation methodology. No funding was used. RESULTS: Our literature review (PROSPERO 2020-CRD42020201241, MEDLINE, EMBASE, Cochrane, Web of Science, January 15, 2020) resulted in 151 studies. Intensive care unit admission was qualitatively not superior for any defined cohort other than by clinical assessment. Poor IS performance was associated with prolonged hospital length of stay, pulmonary complications, and unplanned ICU admission. Noninvasive positive pressure ventilation was associated with 85% reduction in odds of pneumonia ( p < 0.0001) and 81% reduction in odds of mortality ( p = 0.03) in suitable patients without risk of airway loss. Ketamine use demonstrated no significant reduction in pain score but a trend toward reduced opioid use. Epidural and other locoregional analgesia techniques did not affect pneumonia, length of mechanical ventilation, hospital length of stay, or mortality. CONCLUSION: We do not recommend for or against routine ICU admission. We recommend use of IS to inform ICU status and conditionally recommend use of NIPPV in patients without risk of airway loss. We offer no recommendation for or against ketamine, epidural, or other locoregional analgesia. LEVEL OF EVIDENCE: Systematic Review/Meta-analysis; Level IV.

OBJECTIVE: We evaluated the benefit of emergency medical services providers' placing a second intravenous (IV) line in the prehospital trauma setting. Our hypothesis was that the placement of a second IV catheter in trauma does not result in an improvement in heart rate, blood pressure, rehospitalizaton rate, or 30-day mortality. METHODS: A retrospective chart review of 320 trauma patients in a one-year period was conducted at our level I trauma center. All trauma patients who had vascular access obtained prehospitally were included. RESULTS: Patients with two IV lines received an average of 348.4 mL more fluid (95% confidence interval [CI]: 235.6, 461.1; p < 0.0001). No change in heart rate, pulse oximetry, Glasgow Coma Scale score, systolic blood pressure, rehospitalization rate, or 30-day mortality was noted. These effects persisted for patients who were initially tachycardic (heart rate 3.92 bpm; 95% CI ?3.01, 10.82; p = 0.27) or hypotensive (blood pressure 22.00 mmHg; 95% CI ?4.17, 48.16; p = 0.10). CONCLUSIONS: Redundant prehospital IV lines provided no noticeable benefit in physiologic support for trauma patients. When controlling for confounding variables, no significant outcome difference was noted, even in the hypotensive patients. The traditional approach for establishment of a secondary IV line in prehospital trauma patients should not be followed in a dogmatic fashion.

Thoracic skeletal injury is a common outcome of motor vehicle accidents. Skeletal reconstruction is guided by anatomic and physiologic variables dictated by the injury complex. Here we describe a report of a patient who sustained complex trauma to the thorax leading to complete thoracic dissociation. Clinical and operative decision-making is discussed to inform the reader of a proposed ordered protocol and considerations for operative intervention and reconstruction.

INTRODUCTION: The COVID-19 pandemic has resulted in cancellation of medical peer meetings. The Chest Wall Injury Society Annual Summit was scheduled for April 2020. Due to safety concerns, the Society altered the meeting to an online format. The purpose of this paper is to describe how this was accomplished and also to highlight its outcomes. METHODS: An online survey of participants was carried out to assess their views on the educational yield and technical difficulties encountered as compared to in-person meetings. RESULTS: Sixty two of 275 (23%) registered participants filled out the survey. Eighty four percent felt that the educational quality was excellent/good. Seventy five percent and 95% felt in-person meetings are better for education and for networking, respectively. Eighty seven percent preferred in-person meetings in the future but would attend a virtual meeting again. Thirteen percent had technical difficulties accessing the meeting. CONCLUSION: Online meetings are feasible but in-person meetings have more educational and networking value.

BACKGROUND: Prompt drainage of traumatic hemothorax is recommended to prevent empyema and trapped lung. Some patients do not present the day of their trauma, leading to their delayed treatment. Delayed drainage could be challenging as clotted blood may not evacuate through a standard chest tube. We hypothesized that such delays would increase the need for surgery or secondary interventions. METHODS: Our trauma registry was reviewed for patients with a hemothorax admitted to our level 1 trauma center from 1/1/00 to 4/30/19. Patients were included in the delayed group if they received a drainage procedure >24 hours after injury. These patients were matched 1:1 by chest abbreviated injury score to patients who received drainage <24 hours from injury. RESULTS: A total of 19 patients with 22 hemothoraces received delayed drainage. All but 3 patients had a chest tube placed as initial treatment. Four patients received surgery, including 3 who initially had chest tubes placed. Longer time to drainage increased the odds of requiring intrathoracic thrombolytics or surgery. In comparison, 2 patients who received prompt drainage received thrombolytics (P = .11) and none required surgery (P = .02). Patients needed surgery when initial drainage was on or after post-injury day 5, but pigtail catheter drainage was effective 26 days after injury. DISCUSSION: Longer times from injury to intervention are associated with increased likelihood of needing surgery for hemothorax evacuation, but outcomes were not uniform. A larger, multicenter study will be necessary to provide better characterization of treatment outcomes for these patients.

BACKGROUND: Historically, patients with penetrating cardiac injuries have enjoyed the best survival after emergency department thoracotomy (EDT), but further examination of these series reveals a preponderance of cardiac stab wound (SW) survivors with only sporadic cardiac gunshot wound (GSW) survivors. Our primary study objective was to determine which patients requiring EDT for penetrating cardiac or great vessel (CGV) injury are salvageable. METHODS: All patients who underwent EDT for penetrating CGV injuries in two urban, level I trauma centers during 2000 to 2007 were retrospectively reviewed. Demographics, injury (mechanism, anatomic injury), prehospital care, and physiology (signs of life [SOL], vital signs, and cardiac rhythm) were analyzed with respect to hospital survival. RESULTS: The study population (n = 283) comprised young (mean age, 27.1 years +/- 10.1 years) men (96.1%) injured by gunshot (GSW, 88.3%) or SWs (11.7%). Patients were compared by injury mechanism and number of CGV wounds with respect to survival (SW, 24.2%; GSW, 2.8%; p < 0.001; single, 9.5%; multiple, 1.4%; p = 0.003). Three predictors-injury mechanism, ED SOL, and number of CGV wounds-were then analyzed alone and in combination with respect to hospital survival. Only one patient (0.8%) with multiple CGV GSW survived EDT. CONCLUSION: When the cumulative impact of penetrating injury mechanism, ED SOL, and number of CGV wounds was analyzed together, we established that those sustaining multiple CGV GSWs (regardless of ED SOL) were nearly unsalvageable. These results indicate that when multiple CGV GSWs are encountered after EDT, further resuscitative efforts may be terminated without limiting the opportunity for survival.

Importance: Current therapies for traumatic blood loss focus on hemorrhage control and blood volume replacement. Severe hemorrhagic shock, however, is associated with a state of arginine vasopressin (AVP) deficiency, and supplementation of this hormone may decrease the need for blood products in resuscitation. Objective: To determine whether low-dose supplementation of AVP in patients with trauma (hereinafter referred to as trauma patients) and with hemorrhagic shock decreases their need for transfused blood products during resuscitation. Design, Setting, and Participants: This randomized, double-blind placebo-controlled clinical trial included adult trauma patients (aged 18-65 years) who received at least 6 U of any blood product within 12 hours of injury at a single urban level 1 trauma center from May 1, 2013, through May 31, 2017. Exclusion criteria consisted of prehospital cardiopulmonary resuscitation, emergency department thoracotomy, corticosteroid use, chronic renal insufficiency, coronary artery disease, traumatic brain injury requiring any neurosurgical intervention, pregnancy, prisoner status, or AVP administration before enrollment. Data were analyzed from May 1, 2013, through May 31, 2017, using intention to treat and per protocol. Interventions: After administration of an AVP bolus (4 U) or placebo, participants received AVP (≤0.04 U/min) or placebo for 48 hours to maintain a mean arterial blood pressure of at least 65 mm Hg. Main Outcomes: The primary outcome was total volume of blood product transfused. Secondary end points included total volume of crystalloid transfused, vasopressor requirements, secondary complications, and 30-day mortality. Results: One hundred patients underwent randomization (49 to the AVP group and 51 to the placebo group). Patients were primarily young (median age, 27 years [interquartile range {IQR}, 22-25 years]) and male (n = 93) with penetrating trauma (n = 79). Cohort characteristics before randomization were well balanced. At 48 hours, patients who received AVP required significantly less blood products (median, 1.4 [IQR, 0.5-2.6] vs 2.9 [IQR, 1.1-4.8] L; P = .01) but did not differ in requirements for crystalloids (median, 9.9 [IQR, 7.9-13.0] vs 11.0 [8.9-15.0] L; P = .22) or vasopressors (median, 400 [IQR, 0-5900] vs 1400 [IQR, 200-7600] equivalent units; P = .22). Although the groups had similar rates of mortality (6 of 49 [12%] vs 6 of 51 [12%]; P = .94) and total complications (24 of 44 [55%] vs 30 of 47 [64%]; P = .37), the AVP group had less deep venous thrombosis (5 of 44 [11%] vs 16 of 47 [34%]; P = .02). Conclusions and Relevance: Low-dose AVP during the resuscitation of trauma patients in hemorrhagic shock decreases blood product requirements. Additional research is necessary to determine whether including AVP improves morbidity or mortality. Trial Registration: ClinicalTrials.gov identifier: NCT01611935.

Embedded rings in the fingers may cause neurovascular, tendinous, or bony injury. These are very rare injuries usually found in patients with mental illness. To minimize the potentially serious complications, mentally-challenged individuals should have tight rings removed. We present a case of a 41-year-old gentleman with schizophrenia who had two partially embedded rings on his left index finger but consistently refused to have the rings removed. Following appointment of a guardian, the patient was returned for surgery to remove the rings. He recovered without further sequelae.
