RESUMO
BACKGROUND: Advancements in laparoscopic techniques led to the adoption of laparoscopic common bile duct exploration (LCBDE) as an alternative to endoscopic retrograde cholangiopancreatography (ERCP) for management of choledocholithiasis (CD). The goal of this study was to describe the initial experience at a safety net hospital with acute care surgeons performing LCBDE for suspected CD. We hypothesized LCBDE would reduce length of stay and hospital costs compared to laparoscopic cholecystectomy (LC) and ERCP performed in the same hospital admission. METHODS: This was a retrospective case-control study from 2019 to 2023 comparing LCBDE to LC/ERCP among patients diagnosed with CD. Statistical analyses were performed using Mann-Whitney U tests for continuous variables and Chi-square tests for categorical variables. Data reported as median [interquartile range] or research subjects with condition (percentage). RESULTS: A total of 110 LCBDE were performed, while 121 subjects underwent LC and ERCP. Patients in the LCBDE group were more likely to be female with a total of 87 female subjects (77.6%) compared to 76 male subjects (62.8%) (95% CI 1.14-3.74). Initial WBC was lower in the LCBDE group at 8.4 [6.9-11.8] compared to the LC/ERCP group at 10.9 [7.9-13.5] (p = 0.0013). Remaining demographics and lab values were similar between the two groups. Patients who underwent LCBDE had a significantly shorter length of stay at 2 days [1-3] compared to those in the LC/ERCP group at 4 days [3-6] (p < 0.001). Hospital charges for the LCBDE group were $46,685 [$38,687-$56,703] compared to $60,537 [$47,527-$71,739] for the LC/ERCP group (p < 0.001). CONCLUSION: LCBDE is associated with significantly lower hospital costs and shorter length of stay with similar post-operative complication and 30-day readmission rates. Our results show that LCBDE is safe and should be considered as a first-line approach in the management of CD.
RESUMO
Background and Objectives: Previous studies have suggested that early scheduling of the surgical stabilization of rib fractures (SSRF) is associated with superior outcomes. It is unclear if these data are reproducible at other institutions. We hypothesized that early SSRF would be associated with decreased morbidity, length of stay, and total charges. Materials and Methods: Adult patients who underwent SSRF for multiple rib fractures or flail chest were identified in the National Inpatient Sample (NIS) by ICD-10 code from the fourth quarter of 2015 to 2016. Patients were excluded for traumatic brain injury and missing study variables. Procedures occurring after hospital day 10 were excluded to remove possible confounding. Early fixation was defined as procedures which occurred on hospital day 0 or 1, and late fixation was defined as procedures which occurred on hospital days 2 through 10. The primary outcome was a composite outcome of death, pneumonia, tracheostomy, or discharge to a short-term hospital, as determined by NIS coding. Secondary outcomes were length of hospitalization (LOS) and total cost. Chi-square and Wilcoxon rank-sum testing were performed to determine differences in outcomes between the groups. One-to-one propensity matching was performed using covariates known to affect the outcome of rib fractures. Stuart-Maxwell marginal homogeneity and Wilcoxon signed rank matched pair testing was performed on the propensity-matched cohort. Results: Of the 474 patients who met the inclusion criteria, 148 (31.2%) received early repair and 326 (68.8%) received late repair. In unmatched analysis, the composite adverse outcome was lower among early fixation (16.2% vs. 40.2%, p < 0.001), total hospital cost was less (USD114k vs. USD215k, p < 0.001), and length of stay was shorter (6 days vs. 12 days) among early SSRF patients. Propensity matching identified 131 matched pairs of early and late SSRF. Composite adverse outcomes were less common among early SSRF (18.3% vs. 32.8%, p = 0.011). The LOS was shorter among early SSRF (6 days vs. 10 days, p < 0.001), and total hospital cost was also lower among early SSRF patients (USD118k vs. USD183k late, p = 0.001). Conclusion: In a large administrative database, early SSRF was associated with reduced adverse outcomes, as well as improved hospital length of stay and total cost. These data corroborate other research and suggest that early SSRF is preferred. Studies of outcomes after SSRF should stratify analyses by timing of procedure.

PURPOSE: Chest wall injury taxonomy and nomenclature are important components of chest wall injury classification and can be helpful in communicating between providers for treatment planning. Despite the common nature of these injuries, there remains a lack of consensus regarding injury description. The Chest Wall Injury Society (CWIS) developed a taxonomy among surgeons in the field; however, it lacked consensus and clarity in critical areas and collaboration with multidisciplinary partners. We believe an interdisciplinary collaboration between CWIS and American Society of Emergency Radiology (ASER) will improve existing chest wall injury nomenclature and help further research on this topic. METHODS: A collaboration between CWIS and ASER gathered feedback on the consensus recommendations. The workgroup held a series of meetings reviewing each consensus statement, refining the terminology, and contributing additional clarifications from a multidisciplinary lens. RESULTS: After identifying incomplete definitions in the CWIS survey, the workgroup expanded on and clarified the language proposed by the survey. More precise definitions related to rib and costal cartilage fracture quality and location were developed. Proposed changes include more accurate characterization of rib fracture displacement and consistent description of costal cartilage fractures. CONCLUSIONS: The 2019 consensus survey from CWIS provides a framework to discuss chest wall injuries, but several concepts remained unclear. Creating a universally accepted taxonomy and nomenclature, utilizing the CWIS survey and this article as a scaffolding, may help providers communicate the severity of chest wall injury accurately, allow for better operative planning, and provide a common language for researchers in the future.

INTRODUCTION: There is a paucity of data describing opioid prescribing patterns for trauma patients. We investigated pain medication regimens prescribed at discharge for patients with traumatic rib fractures, as well as potential variables predictive of opioid prescribing. METHODS: A single-center, retrospective analysis was performed of 337 adult patients presenting with ≥1 traumatic rib fractures between January and December 2019. The primary outcome was oral morphine milligram equivalents (MME) prescribed on discharge. A multivariable logistic regression analysis was performed to determine factors independently associated with above median (150) MME prescription at discharge. RESULTS: The majority of patients were male (68.8%) with a median age of 53 y. Blunt trauma accounted for 97.3% of cases with a median Injury Severity Score(ISS) of 10. Locoregional pain procedures were utilized in 16.9% of patients. Opioids were the most common analgesic prescribed at discharge, and 74.1% of patients prescribed opioids on discharge were also prescribed a non-opioid adjunct. On multivariable analysis, daily MME prescribed during hospitalization (OR 1.01, 95% CI 1.01-1.02, P < 0.01) and number of rib fractures (OR 2.26, 95% CI 1.36-3.74, P < 0.01) were predictive of high MME prescribed on discharge. CONCLUSIONS: For patients with traumatic rib fractures, daily MME during hospitalization and number of rib fractures were predictive of high MME prescribing on discharge. Further prospective studies evaluating strategies for pain management and protocolized approaches to opioid prescribing are needed to reduce unnecessary and inappropriate opioid use in this patient population.

BACKGROUND: Current decision algorithms involving surgical stabilization of rib fractures (SSRF) do not consider either specific fracture locations or other chest wall bony injuries. Our objective was to characterize the impact of scapula fractures on morbidity among patients who underwent fixation of sub-scapular rib fractures. We hypothesized that an ipsilateral scapula fracture was associated with poor acute and long-term outcomes. METHODS: Retrospective review of two institutions' prospectively maintained SSRF databases (October 2010 to January 2019). Patients who underwent repair of ≥ 1 sub-scapular rib fracture were included. Patients were grouped by the presence of an ipsilateral scapula fracture. Outcomes were acute SSRF complications, long-term rib implant removal, and quality of life via phone survey. RESULTS: A total of 144 patients were analyzed; 53 (36.8%) had an ipsilateral scapula fracture. Patients with a scapula fracture had a higher injury severity score (p = 0.02), degree of pulmonary contusion (p < 0.01), and RibScore (p < 0.01). The overall incidence of both acute re-operation (n = 4, 2.8%) and long-term implant removal (n = 5, 3.8%) following SSRF was low and did not vary by the presence of a scapula fracture. Only twenty-one patients completed phone questionnaires a median of 38 months after SSRF; both shoulder and rib outcomes were excellent and did not vary by the presence of a scapula fracture. CONCLUSION: Ipsilateral scapula fractures are common in patients who undergo surgical stabilization of sub-scapular rib fractures. Despite higher injury severity, patients with an ipsilateral scapula fracture did not incur worse outcomes.

OBJECTIVES: This study investigated associations between patient and injury characteristics and false-negative (FN) focused assessment with sonography for trauma (FAST) in pediatric blunt abdominal trauma (BAT). We also evaluated the effects of FN FAST on in-hospital mortality and length of stay (LOS) variables. METHODS: This retrospective cohort studied children younger than 18 years between January 1, 2002, and December 31, 2013, with BAT, documented FAST, and pathologic fluid on computed tomography, surgery, or autopsy. Multivariable and bivariate analyses were used to assess associations between FN FAST and patient injury characteristics, mortality, and hospital LOS. RESULTS: A total of 141 pediatric BAT patients with pathologic free fluid were included. There were no patient or injury characteristics, which conferred increased odds of an FN FAST. Splenic and bladder injury were negatively associated with FN FAST odds ratio of 0.4 (95% confidence interval [CI], 0.2-0.8) and 0.1 (95% CI, 0-0.8). Abbreviated Injury Scale score of 4 or greater to the abdomen and extremity was negatively associated with FN FAST odds ratio of 0.1 (95% CI, 0-0.3) and 0.3 (95% CI, 0.1-0.9). There was no association between FN FAST and mortality. Patients with an FN FAST had increased hospital LOS after controlling for sex, age, and Injury Severity Score. CONCLUSIONS: Clinicians need to be cautious applying a single initial FAST to patients with minor abdominal trauma or with suspected injuries to organs other than the spleen or bladder. Formalized studies to develop risk stratification tools could allow clinicians to integrate FAST into the pediatric patient population in the safest manner possible.

BACKGROUND: Plasma is integral to haemostatic resuscitation after injury, but the timing of administration remains controversial. Anticipating approval of lyophilised plasma by the US Food and Drug Administration, the US Department of Defense funded trials of prehospital plasma resuscitation. We investigated use of prehospital plasma during rapid ground rescue of patients with haemorrhagic shock before arrival at an urban level 1 trauma centre. METHODS: The Control of Major Bleeding After Trauma Trial was a pragmatic, randomised, single-centre trial done at the Denver Health Medical Center (DHMC), which houses the paramedic division for Denver city. Consecutive trauma patients in haemorrhagic shock (defined as systolic blood pressure [SBP] ≤70 mm Hg or 71-90 mm Hg plus heart rate ≥108 beats per min) were assessed for eligibility at the scene of the injury by trained paramedics. Eligible patients were randomly assigned to receive plasma or normal saline (control). Randomisation was achieved by preloading all ambulances with sealed coolers at the start of each shift. Coolers were randomly assigned to groups 1:1 in blocks of 20 according to a schedule generated by the research coordinators. If the coolers contained two units of frozen plasma, they were defrosted in the ambulance and the infusion started. If the coolers contained a dummy load of frozen water, this indicated allocation to the control group and saline was infused. The primary endpoint was mortality within 28 days of injury. Analyses were done in the as-treated population and by intention to treat. This trial is registered with ClinicalTrials.gov, number NCT01838863. FINDINGS: From April 1, 2014, to March 31, 2017, paramedics randomly assigned 144 patients to study groups. The as-treated analysis included 125 eligible patients, 65 received plasma and 60 received saline. Median age was 33 years (IQR 25-47) and median New Injury Severity Score was 27 (10-38). 70 (56%) patients required blood transfusions within 6 h of injury. The groups were similar at baseline and had similar transport times (plasma group median 19 min [IQR 16-23] vs control 16 min [14-22]). The groups did not differ in mortality at 28 days (15% in the plasma group vs 10% in the control group, p=0·37). In the intention-to-treat analysis, we saw no significant differences between the groups in safety outcomes and adverse events. Due to the consistent lack of differences in the analyses, the study was stopped for futility after 144 of 150 planned enrolments. INTERPRETATION: During rapid ground rescue to an urban level 1 trauma centre, use of prehospital plasma was not associated with survival benefit. Blood products might be beneficial in settings with longer transport times, but the financial burden would not be justified in an urban environment with short distances to mature trauma centres. FUNDING: US Department of Defense.

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.

PURPOSE: Fat emboli syndrome is a rare but well-described complication of long-bone fractures classically characterised by a triad of respiratory failure, mental status changes and petechial rash. In this paper, we present the case of a patient who sustained bilateral femoral fractures and subsequently developed FES. Our aim was to review and summarise the current literature regarding the pathophysiology and management of fat emboli syndrome (FES) and propose an algorithm for treating patients with bilateral femoral fractures to reduce the risk of FES. METHODS: A literature analysis was performed to determine implications in the clinical setting. RESULTS: Currently, there exists little high-quality evidence to guide the orthopaedic surgeon in identifying patients at highest risk of FES or in preventing FES in patients with multiple long-bone fractures. However, the literature does suggest that the risk is directly related to the volume of marrow displaced and inversely related to both the time to fracture stabilisation and the respiratory reserve of the patient. Based on these correlations, we propose an algorithm for treating patients with bilateral femoral fractures, taking into consideration haemodynamic and pulmonary stability. CONCLUSIONS: Our algorithm for managing bilateral femoral fractures prioritises early stabilisation with external fixation, staged intramedullary nailing and conversion to plate fixation if FES develops. This protocol is meant to be the basis of future investigations of optimal treatment strategies.

BACKGROUND: Massive transfusion protocols (MTPs) have become standard of care in the management of bleeding injured patients, yet strategies to guide them vary widely. We conducted a pragmatic, randomized clinical trial (RCT) to test the hypothesis that an MTP goal directed by the viscoelastic assay thrombelastography (TEG) improves survival compared with an MTP guided by conventional coagulation assays (CCA). METHODS: This RCT enrolled injured patients from an academic level-1 trauma center meeting criteria for MTP activation. Upon MTP activation, patients were randomized to be managed either by an MTP goal directed by TEG or by CCA (ie, international normalized ratio, fibrinogen, platelet count). Primary outcome was 28-day survival. RESULTS: One hundred eleven patients were included in an intent-to-treat analysis (TEG = 56, CCA = 55). Survival in the TEG group was significantly higher than the CCA group (log-rank P = 0.032, Wilcoxon P = 0.027); 20 deaths in the CCA group (36.4%) compared with 11 in the TEG group (19.6%) (P = 0.049). Most deaths occurred within the first 6 hours from arrival (21.8% CCA group vs 7.1% TEG group) (P = 0.032). CCA patients required similar number of red blood cell units as the TEG patients [CCA: 5.0 (2-11), TEG: 4.5 (2-8)] (P = 0.317), but more plasma units [CCA: 2.0 (0-4), TEG: 0.0 (0-3)] (P = 0.022), and more platelets units [CCA: 0.0 (0-1), TEG: 0.0 (0-0)] (P = 0.041) in the first 2 hours of resuscitation. CONCLUSIONS: Utilization of a goal-directed, TEG-guided MTP to resuscitate severely injured patients improves survival compared with an MTP guided by CCA and utilizes less plasma and platelet transfusions during the early phase of resuscitation.

OBJECTIVE: To evaluate the efficacy of IV iron supplementation of anemic, critically ill trauma patients. DESIGN: Multicenter, randomized, single-blind, placebo-controlled trial. SETTING: Four trauma ICUs. PATIENTS: Anemic (hemoglobin < 12 g/dL) trauma patients enrolled within 72 hours of ICU admission and with an expected ICU length of stay of more than or equal to 5 days. INTERVENTIONS: Randomization to iron sucrose 100 mg IV or placebo thrice weekly for up to 2 weeks. MEASUREMENTS AND MAIN RESULTS: A total of 150 patients were enrolled. Baseline iron markers were consistent with functional iron deficiency: 134 patients (89.3%) were hypoferremic, 51 (34.0%) were hyperferritinemic, and 64 (42.7%) demonstrated iron-deficient erythropoiesis as evidenced by an elevated erythrocyte zinc protoporphyrin concentration. The median baseline transferrin saturation was 8% (range, 2-58%). In the subgroup of patients who received all six doses of study drug (n = 57), the serum ferritin concentration increased significantly for the iron as compared with placebo group on both day 7 (808.0 ng/mL vs 457.0 ng/mL, respectively, p < 0.01) and day 14 (1,046.0 ng/mL vs 551.5 ng/mL, respectively, p < 0.01). There was no significant difference between groups in transferrin saturation, erythrocyte zinc protoporphyrin concentration, hemoglobin concentration, or packed RBC transfusion requirement. There was no significant difference between groups in the risk of infection, length of stay, or mortality. CONCLUSIONS: Iron supplementation increased the serum ferritin concentration significantly, but it had no discernible effect on transferrin saturation, iron-deficient erythropoiesis, hemoglobin concentration, or packed RBC transfusion requirement. Based on these data, routine IV iron supplementation of anemic, critically ill trauma patients cannot be recommended (NCT 01180894).

ABSTRACT: Ten percent 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 comorbid conditions. Death due to rib fracture is mostly caused by pneumonia because of inability to expectorate and take deep breaths. Over the last 25 to 30 years, there has been renewed interest in surgical stabilization of rib fractures (SSRF), known colloquially as "rib plating." This review will present what you need to know in regard to triage decisions on whether 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 nonoperative treatment modalities that should be implemented prior to operation.

OBJECTIVES: To determine the effectiveness of an updated protocol that increased the transfusion threshold to perform preperitoneal pelvic packing in patients with pelvic ring injuries and hemodynamic instability (HDI). DESIGN: Retrospective review. SETTING: Urban level 1 trauma center. PATIENTS SELECTION CRITERIA: Severely injured (injury severity score > 15) patients with pelvic ring injuries treated before and after increasing the threshold to perform preperitoneal pelvic packing from 2 to 4 units of red blood cells (RBCs). HDI was defined as a systolic blood pressure <90 mm Hg. OUTCOME MEASURES AND COMPARISONS: Mortality from hemorrhage, anterior pelvic space infections, and venous thromboembolisms before and after increasing preperitoneal pelvic packing threshold. RESULTS: One hundred sixty-six patients were included: 93 treated under the historical protocol and 73 treated under the updated protocol. HDI was present in 46.2% (n = 43) of the historical protocol group and 49.3% (n = 36) of the updated protocol group (P = 0.69). The median age of patients with HDI was 35.0 years (interquartile range 26.0-52.0), 74.7% (n = 59) were men, and the median injury severity score was 41.0 (interquartile range 29.0-50.0). Patients with HDI in the updated protocol group had a lower heart rate on presentation (105.0 vs. 120.0; P = 0.004), required less units of RBCs over the first 24 hours (6.0 vs. 8.0, P = 0.03), and did not differ in age, injury severity score, systolic blood pressure on arrival, base deficit or lactate on arrival, resuscitative endovascular balloon occlusion of the aorta, resuscitative thoracotomy, angioembolization, or anterior pelvis open reduction internal fixation (P > 0.05). The number of PPPs performed decreased under the new protocol (8.3% vs. 65.1%, P < 0.0001), and there were fewer anterior pelvic infections (0.0% vs. 13.9%, P = 0.02), fewer VTEs (8.3% vs. 30.2%; P = 0.02), and no difference in deaths from acute hemorrhagic shock (5.6% vs. 7.0%, P = 1.00). CONCLUSIONS: Increasing the transfusion threshold from 2 to 4 units of red blood cells to perform pelvic packing in severely injured patients with pelvic ring injuries decreased anterior pelvic space infections and venous thromboembolisms without affecting deaths from acute hemorrhage. LEVEL OF EVIDENCE: Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.

BACKGROUND: Conventional rapid thrombelastography (rTEG) cannot differentiate fibrinolysis shutdown from hypofibrinolysis, as both of these patient populations have low fibrinolytic activity. Tissue plasminogen activator (tPA) TEG can identify depletion of fibrinolytic inhibitors, and its use in combination with rTEG has the potential to differentiate all 3 pathologic fibrinolytic phenotypes after trauma. We hypothesize tPA-TEG and rTEG in combination can further stratify fibrinolysis phenotypes postinjury to better stratify risk for mortality. STUDY DESIGN: Adult trauma patients (981) with both rTEG and tPA-TEG performed less than 2 hours postinjury were included. rTEG lysis at 30 minutes after maximum amplitude (LY30) was used to initially define fibrinolysis phenotypes (hyperfibrinolysis >3%, physiologic 0.9% to 3%, and shutdown <0.9%), with Youden Index then used to define pathologic extremes of tPA-TEG LY30 (tPA sensitive [depletion of fibrinolytic inhibitors] vs resistant) resulting in 9 groups that were assessed for risk of death. RESULTS: The median New Injury Severity Score was 22, 21% were female, 45% had penetrating injury, and overall mortality was 13%. The tPA-TEG LY30 inflection point for increased mortality was >35.5% (tPA sensitive, odds ratio mortality 9.2, p < 0.001) and <0.3% (tPA resistance, odds ratio mortality 6.3, p = 0.04). Of the 9 potential fibrinolytic phenotypes, 5 were associated with increased mortality. Overall, the 9 phenotypes provided a significantly better prediction of mortality than rTEG or tPA-TEG alone (areas under the operating characteristics curves = 0.80 vs 0.63 and 0.75, respectively, p < 0.0001). These could be condensed to 3 pathologic phenotypes (true hyperfibrinolysis, early fibrinolysis shutdown, and hypofibrinolysis). CONCLUSIONS: The combination of rTEG and tPA-TEG increases the ability to predict mortality and suggests patient-specific strategies for improved outcomes.

INTRODUCTION: The progression of pulmonary contusions remains poorly understood. This study aimed to measure the radiographic change in pulmonary contusions over time and evaluate the association of the radiographic change with clinical outcomes and surgical stabilization of rib fractures (SSRF). METHODS: This retrospective cohort study included adults admitted with three or more displaced rib fractures or flail segment on trauma CT and when a chest CT was repeated within one week after trauma. Radiographic severity of pulmonary contusions was assessed using the Blunt Pulmonary Contusion Score (BPC18). Logistic regression was performed to evaluate the relation between SSRF and worsening contusions on repeat CT, adjusted for potential confounders. RESULTS: Of 231 patients, 56 (24%) had a repeat CT scan. Of these, 55 (98%) had pulmonary contusion on the first CT scan with a median BPC18 score of 5 (P25-P75 3-7). Repeat CTs showed an overall decrease of the median BPC18 score to 4 (P25-P75 2-6, P = .02), but demonstrated a worsening of the pulmonary contusion in 16 patients (29%). All repeat CTs conducted within 12 hours post-injury demonstrated increasing BPC18. Radiographic worsening of pulmonary contusions was not associated with SSRF, nor with worse respiratory outcomes or intensive care length of stay, compared to patients with radiographically stable or improving contusions. DISCUSSION: In patients with severe rib fracture patterns who undergo repeat imaging, pulmonary contusions are prevalent and become radiographically worse within at least the first 12 hours after injury. No association between radiographic worsening and clinical outcomes was found.

Background: Pneumonia is associated with increased morbidity and costs in the intensive care unit (ICU). Its early identification is key for optimal outcomes, but early biomarkers are lacking. Studies suggest that fibrinolysis resistance (FR) after major abdominal surgery is linked to an increased risk of infection. Patients and Methods: Patients in a randomized controlled trial for hemorrhagic shock were evaluated for FR. Fibrinolysis resistance was quantified by thrombelastography with exogenous tissue plasminogen activator (tPA-TEG) at 24- and 48-hours post-injury and measuring LY30 (%). A receiver-operating characteristics (ROC) curve analysis was used to identify a cutoff for increased risk of pneumonia, which was then validated in ICU patients at risk for venous thromboembolism (VTE). Multivariable logistic regression was used to control for confounders. Results: Forty-nine patients in the hemorrhagic shock cohort had tPA-TEGs at 24- and 48-hours (median ISS, 27; 7% pneumonia). A composite tPA-TEG LY30 of less than 4% at 24 and 48 hours was found to be the optimal cutoff for increased risk of pneumonia. This cohort had a seven-fold increased rate of pneumonia (4% vs. 28%; p = 0.048). Eighty-eight patients in the VTE cohort had tPA-TEGs at 24 and 48 hours post-ICU admission (median ISS, 28; 6% pneumonia). The tPA-TEG LY30 of less than 4% was associated with a 10-fold increased rate of pneumonia (19% vs. 1.5%; p = 0.002). In patients with traumatic brain injury, the same association was found (33% vs. 3.2%; p = 0.006). Adjusting for confounders, the tPA-TEG persisted as a substantial risk factor for pneumonia (adjusted odds ratio [OR], 35.7; 95% confidence interval [CI], 1.9-682; p = 0.018). Conclusions: Fibrinolysis resistance quantified by tPA-TEG within 48 hours of ICU admission is associated with an increased risk of pneumonia in patients in hemorrhagic shock and those at risk for VTE. Prospective validation of the tPA-TEG LY30 optimal cutoff for pneumonia and further investigation into whether endogenous FR is a cause of an altered immunity is warranted.

BACKGROUND: Surgical stabilization of rib fractures (SSRF) is increasingly performed, however the outcome of patients undergoing SSRF while on pre-injury antithrombotic therapy remains unknown. We compared surgical variables and outcomes of patients who were and were not on antithrombotic therapy. We hypothesize pre-injury anticoagulation is associated with delay in SSRF and worse outcomes. METHODS: For this retrospective cohort study, we queried the Chest Injury International Database, for patients undergoing SSRF between 08/2018 and 03/2022. Antithrombotic therapy was categorized into antiplatelet and anticoagulant use. Primary outcome was time from admission to SSRF. Secondary outcomes included SSRF duration and complications. Numerical data were presented as median (IQR), categorical data as number (%). Inverse probability weighting was used to control for confounding. RESULTS: Two hundred and eighteen SSRF patients were included, 25 (11 %) were on antithrombotic therapy. These patients were older (72 years, (65-80) versus 57 years, (43-66); p < 0.001) with lower ISS (14, (10-20) versus 21, (14-30); p = 0.002). Time from admission to SSRF was comparable (2 days, (1-4) versus 2 days, (1-4); p = 0.37) as was operative time (154 mins, (120.0-212.0) versus 177 mins, (143.0-210.0); p = 0.34). Patients using antithrombotics had fewer ICU-free days (24 (22-26) versus 28 (23-28); p = 0.003) but more ventilator free days (28, (28-28) versus 27 (27-28); p < 0.008). After adjusting for confounding, pre-injury anticoagulation was not significantly associated with delayed SSRF (Relative Risk, RR=1.37, 95 % CI 0.30-6.24), operative time (RR=1.07, 95 % CI0.88-1.31), IFD <=28 (RR=2.05, 95 %CI:0.33-12.67), VFD<=27 (RR=0.71, 95 %CI:0.15-3.48) or complications (RR=0.55, 95 % CI0.06-5.01). CONCLUSION: Pre-injury antithrombotic drug use neither delayed SSRF nor impacted operative time in patients requiring SSRF and was not associated with increased risk of complications. Our data suggest SSRF can be safely performed without delay in patients who use anticoagulation pre-injury. LEVEL OF EVIDENCE: IV. STUDY TYPE: Therapeutic/care management.

BACKGROUND: Complex pleural space infections often require treatment with multiple doses of intrapleural tissue plasminogen activator (tPA) and deoxyribonuclease, with treatment failure frequently necessitating surgery. Pleural infections are rich in neutrophils, and neutrophil elastase degrades plasminogen, the target substrate of tPA, that is required to generate fibrinolysis. We hypothesized that pleural fluid from patients with pleural space infection would show high elastase activity, evidence of inflammatory plasminogen degradation, and low fibrinolytic potential in response to tPA that could be rescued with plasminogen supplementation. RESEARCH QUESTION: Does neutrophil elastase degradation of plasminogen contribute to intrapleural fibrinolytic failure? STUDY DESIGN AND METHODS: We obtained infected pleural fluid and circulating plasma from hospitalized adults (n = 10) with institutional review board approval from a randomized trial evaluating intrapleural fibrinolytics vs surgery for initial management of pleural space infection. Samples were collected before the intervention and on days 1, 2, and 3 after the intervention. Activity assays, enzyme-linked immunosorbent assays, and Western blot analysis were performed, and turbidimetric measurements of fibrinolysis were obtained from pleural fluid with and without exogenous plasminogen supplementation. Results are reported as median (interquartile range) or number (percentage) as appropriate, with an α value of .05. RESULTS: Pleural fluid elastase activity was more than fourfold higher (P = .02) and plasminogen antigen levels were more than threefold lower (P = .04) than their corresponding plasma values. Pleural fluid Western blot analysis demonstrated abundant plasminogen degradation fragments consistent with elastase degradation patterns. We found that plasminogen activator inhibitor 1 (PAI-1), the native tPA inhibitor, showed high antigen levels before the intervention, but the overwhelming majority of this PAI-1 (82%) was not active (P = .003), and all PAI-1 activity was lost by day 2 after the intervention in patients receiving intrapleural tPA and deoxyribonuclease. Finally, using turbidity clot lysis assays, we found that the pleural fluid of 9 of 10 patients was unable to generate a significant fibrinolytic response when challenged with tPA and that plasminogen supplementation rescued fibrinolysis in all patients. INTERPRETATION: Our findings suggest that inflammatory plasminogen deficiency, not high PAI-1 activity, is a significant contributor to intrapleural fibrinolytic failure.

RESUMO
BACKGROUND: Over the last two decades, the acute management of rib fractures has changed significantly. In 2021, the Chest Wall injury Society (CWIS) began recognizing centers that epitomize their mission as CWIS Collaborative Centers. The primary aim of this study was to determine the resources, surgical expertise, access to care, and institutional support that are present among centers. METHODS: A survey was performed including all CWIS Collaborative Centers evaluating the resources available at their hospital for the treatment of patients with chest wall injury. Data about each chest wall injury center care process, availability of resources, institutional support, research support, and educational offerings were recorded. RESULTS: Data were collected from 20 trauma centers resulting in an 80% response rate. These trauma centers were made up of 5 international and 15 US-based trauma centers. Eighty percent (16 of 20) have dedicated care team members for the evaluation and management of rib fractures. Twenty-five percent (5 of 20) have a dedicated rib fracture service with a separate call schedule. Staffing for chest wall injury clinics consists of a multidisciplinary team: with attending surgeons in all clinics, 80% (8 of 10) with advanced practice providers and 70% (7 of 10) with care coordinators. Forty percent (8 of 20) of centers have dedicated rib fracture research support, and 35% (7 of 20) have surgical stabilization of rib fracture (SSRF)-related grants. Forty percent (8 of 20) of centers have marketing support, and 30% (8 of 20) have a web page support to bring awareness to their center. At these trauma centers, a median of 4 (1-9) surgeons perform SSRFs. In the majority of trauma centers, the trauma surgeons perform SSRF. CONCLUSION: Considerable similarities and differences exist within these CWIS collaborative centers. These differences in resources are hypothesis generating in determining the optimal chest wall injury center. These findings may generate several patient care and team process questions to optimize patient care, patient experience, provider satisfaction, research productivity, education, and outreach.
