Operative Treatment and Clinical Outcomes in Peripheral Vascular Trauma: The Combined Experience of Two Centers in the Endovascular Era.

BACKGROUND: Arterial traumas of the extremities are quite rare in civilian records; nevertheless, patients with trauma of limbs are admitted daily in emergency departments worldwide. The up-to-date information about epidemiology and treatment (open vs. endovascular surgery) comes from war records and it is not always easy getting data on mortality and morbidity in these patients. The aim of this study is to analyze the approach (open or endovascular) and the outcome of patients with vascular trauma of upper limbs (from the subclavian artery) and/or lower limbs (distal to the inguinal ligament), in the greater Milan area. METHODS: A retrospective analysis was conducted on data recorded by the emergency departments of two hospitals of the greater Milan between 2009 and 2017. We collected all patients with arterial injuries of the limbs in terms of demography, injury patterns, clinical status at admission, therapy (open or endovascular approach), and outcomes in terms of limb salvage and survival. RESULTS: We studied 52 patients with vascular trauma of extremities. The main mechanism of trauma was road accident (48.1%), followed by criminal acts (32.7%), self-endangering behavior (13.5%), work (3.8%), and sport accidents (1.9%). Associated lesions (orthopedic, neurological, and/or venous lesions of the limbs) were present in 39 patients (75%). All patients underwent emergency surgery, forty-six patients (88.5%) by open repair (polytetrafluoroethylene or greater saphenous vein bypass grafts, arterial suture or ligation), whereas endovascular approach was used only in 6 patients (11.5%), all treated with embolization. The overall postoperative mortality rate was 5.7% (3 patients). Among survivors, we report 5 major amputations of the lower limbs, 3 of them after bypass graft infection, and 2 after graft failure. The rate of limb salvage was 90.4%. CONCLUSIONS: Isolated arterial trauma of the extremities are rare, usually they occur in the setting of multiple trauma patients. Despite progresses in surgical techniques, there are still controversies in diagnosis and treatment of these patients. We treated most cases with open surgery (n = 46), choosing endovascular approach (embolization performed mainly by interventional radiologists) in difficult anatomic districts. We believe that, during decision-making of the surgical strategy, it is important to consider the anatomical site of lesions and the general condition of the patients. Moreover, in case of multiple trauma, we suggest a multidisciplinary approach to provide the best medical care to the victims.

Torso computed tomography in blunt trauma patients with normal vital signs can be avoided using non-invasive tests and close clinical evaluation.

PURPOSE: To determine whether torso CT can be avoided in patients who experience high-energy blunt trauma but have normal vital signs. METHODS: High-energy blunt trauma patients with normal vital signs were retrieved retrospectively from our registry. We reviewed 1317 patients (1027 men and 290 women) and 761 (57.8%) fulfilled the inclusion criteria. All patients were initially evaluated at the emergency room (ER), with a set of tests, part of a specific protocol. Patients with at least one altered exam at initial examination or after six-hour observation received a torso CECT. Sensitivity, specificity, accuracy, positive (PPV) and negative predictive values (NPV), and likelihood ratio (LH) of the protocol were evaluated. RESULTS: Of 761 patients, 354 (46.5%) received torso CECT because of the positive ER test, with 330 being true positive and 24 being false positive. The remaining 407 patients were negative at ER tests and did not receive torso CECT, showing a significantly (P < 0.001) lower Injury Severity Score (ISS). The positive and negative LH of the protocol to detect torso injuries were respectively 16.5 and 0.01 (overall accuracy of 0.96). CONCLUSIONS: Torso CT can be avoided without adverse clinical outcomes in patients who experience high-energy blunt trauma, are hemodynamically stable, and have normal initial laboratory and imaging tests.

Emergency CT for assessment and management of blunt traumatic splenic injuries at a Level 1 Trauma Center: 13-year study.

PURPOSE: To determine the relationship between multidetector computed tomography (MDCT) findings, management strategies, and ultimate clinical outcomes in patients with splenic injuries secondary to blunt trauma. MATERIALS AND METHODS: This Institutional Review Board-approved study collected 351 consecutive patients admitted at the Emergency Department (ED) of a Level I Trauma Center with blunt splenic trauma between October 2002 and November 2015. Their MDCT studies were retrospectively and independently reviewed by two radiologists to grade splenic injuries according to the American Association for the Surgery of Trauma (AAST) organ injury scale (OIS) and to detect intraparenchymal (type A) or extraparenchymal (type B) active bleeding and/or contained vascular injuries (CVI). Clinical data, information on management, and outcome were retrieved from the hospital database. Statistical analysis relied on Student's t, chi-squared, and Cohen's kappa tests. RESULTS: Emergency multiphase MDCT was obtained in 263 hemodynamically stable patients. Interobserver agreement for both AAST grading of injuries and vascular lesions was excellent (k = 0.77). Operative management (OM) was performed in 160 patients (45.58% of the whole cohort), and high-grade (IV and V) OIS injuries and type B bleeding were statistically significant (p < 0.05) predictors of OM. Nonoperative management (NOM) failed in 23 patients out of 191 (12.04%). In 75% of them, NOM failure occurred within 30 h from the trauma event, without significant increase of mortality. Both intraparenchymal and extraparenchymal active bleeding were predictive of NOM failure (p < 0.05). CONCLUSION: Providing detection and characterization of parenchymal and vascular traumatic lesions, MDCT plays a crucial role for safe and appropriate guidance of ED management of splenic traumas and contributes to the shift toward NOM in hemodynamically stable patients.

Spontaneous hepatic rupture during pregnancy in a patient with peliosis hepatis.

Spontaneous hepatic rupture (SHR) during pregnancy is a rare but well known complication and it usually occurs alongside eclampsia or HELLP syndrome. SHR in uncomplicated pregnancy is extremely rare and can be associated to different undiagnosed pathological conditions. We report the case of a nulliparous woman, 27 weeks pregnant, with a peliosis hepatis, previously unknown, who was admitted to our unit due to SHR and massive hemoperitoneum. The conception was obtained by embryo transfer after multiple attempts of hormone-supported cycles using estrogens and progesterone. After emergency laparotomy the patient was submitted to deliver of the dead foetus and damage control of the hepatic bleeding source. At relaparotomy a right posterior sectionectomy (segments VI and VII) and segmentectomy of segment V were performed. The patient was discharged in good physical conditions after 18 days from admission. If hepatic rupture is suspected in a pregnant patient a collaborative multidisciplinary approach is mandatory. The cornerstones of medical and surgical management are highlighted. At the best of our knowledge this is the first case of SHR in a pregnant woman with peliosis hepatis. A possible correlation of an increased risk for SHR in a pregnant patient who was submitted to several attempts for embryo transfer is discussed. The relevant scientific literature of the possible causative role of the estrogen therapy in inducing politic liver damage is also reviewed.

State of the art of trauma teams in Italy: A nationwide study.

Trauma teams play a vital role in providing prompt and specialized care to trauma patients. This study aims to provide a comprehensive description of the presence and organization of trauma teams in Italy. A nationwide cross-sectional epidemiological study was conducted between July and October 2022, involving interviews with 137 designated trauma centers. Centers were stratified based on level: higher specialized trauma centers (CTS), intermediate level trauma centers (CTZ + N) and district general hospital with trauma capacity (CTZ). A standardized structured interview questionnaire was used to gather information on hospital characteristics, trauma team prevalence, activation pathways, structure, components, leadership, education, and governance. Descriptive statistics were used for analysis. Results showed that 53 % of the centers had a formally defined trauma team, with higher percentages in CTS (73 %) compared to CTZ + N (49 %) and CTZ (39 %). The trauma team activation pathway varied among centers, with pre-alerts predominantly received from emergency medical services. The study also highlighted the lack of formally defined massive transfusion protocols in many centers. The composition of trauma teams typically included airway and procedure doctors, nurses, and healthcare assistants. Trauma team leadership was predetermined in 59 % of the centers, with anesthesiologists/intensive care physicians often assuming this role. The study revealed gaps in trauma team education and governance, with a lack of specific training for trauma team leaders and low utilization of simulation-based training. These findings emphasize the need for improvements in trauma management education, governance, and the formalization of trauma teams. This study provides valuable insights that can guide discussions and interventions aimed at enhancing trauma care at both local and national levels in Italy.

Comparison between level 1 and level 2 trauma centers for the management of splenic blunt trauma.

INTRODUCTION: The management of blunt splenic trauma has evolved in the last years, from mainly operative approach to the non-operative management (NOM). The aim of this study is to investigate whether trauma center (TC) designation (level 1 and level 2) affects blunt splenic trauma management. METHODS: A retrospective analysis of blunt trauma patients with splenic injury admitted to 2 Italian TCs, Niguarda (level 1) and San Carlo Borromeo (level 2), was performed, receiving either NOM or emergency surgical treatment, from January 1, 2015 to December 31, 2020. Univariate comparison was performed between the two centers, and multivariate analysis was carried out to find predictive factors associated with NOM and splenectomy. RESULTS: 181 patients were included in the study, 134 from level 1 and 47 from level 2 TCs. The splenectomy/emergency laparotomy ratio was inferior at level 1 TC for high-grade splenic injuries (30.8% for level 1 and 100% for level 2), whose patients presented higher incidence of other injuries. Splenic NOM failure was registered in only one case (3.3%). At multivariate analysis, systolic pressure, spleen organ injury scale (OIS) and injury severity score (ISS) resulted significant predictive factors for NOM, and only spleen OIS was predictive factor for splenectomy (Odds Ratio 0.14, 0.04-0.49 CI 95%, P < .01). CONCLUSION: Both level 1 and 2 trauma centers demonstrated application of NOM with a high rate of success with some management difference in the treatment and outcome of patients with splenic injuries between the two types of TCs.

Identifying Trauma Patients in Need for Emergency Surgery in the Prehospital Setting: The Prehospital Prediction of In-Hospital Emergency Treatment (PROPHET) Study.

Prehospital field triage often fails to accurately identify the need for emergent surgical or non-surgical procedures, resulting in inefficient resource utilization and increased costs. This study aimed to analyze prehospital factors associated with the need for emergent procedures (such as surgery or interventional angiography) within 6 h of hospital admission. Additionally, our goal was to develop a prehospital triage tool capable of estimating the likelihood of requiring an emergent procedure following hospital admission. We conducted a retrospective observational study, analyzing both prehospital and in-hospital data obtained from the Lombardy Trauma Registry. We conducted a multivariable logistic regression analysis to identify independent predictors of emergency procedures within the first 6 h from admission. Subsequently, we developed and internally validated a triage score composed of factors associated with the probability of requiring an emergency procedure. The study included a total of 3985 patients, among whom 295 (7.4%) required an emergent procedure within 6 h. Age, penetrating injury, downfall, cardiac arrest, poor neurological status, endotracheal intubation, systolic pressure, diastolic pressure, shock index, respiratory rate and tachycardia were identified as predictors of requiring an emergency procedure. A triage score generated from these predictors showed a good predictive power (AUC of the ROC curve: 0.81) to identify patients requiring an emergent surgical or non-surgical procedure within 6 h from hospital admission. The proposed triage score might contribute to predicting the need for immediate resource availability in trauma patients.

The Comprehensive Facial Injury (CFI) Score Is an Early Predictor of the Management for Mild, Moderate and Severe Facial Trauma.

Identifying groups of patients with homogeneous characteristics and comparable outcomes improves clinical activity, patients' management, and scientific research. This study aims to define mild, moderate, and severe facial trauma by validating two cut-off values of the Comprehensive Facial Injury (CFI) score and describing their foreseeable clinical needs to create a useful guide in patient management, starting from the first evaluation. The individual CFI score, overall surgical time, and length of hospitalization are calculated for a sample of 1400 facial-injured patients. Receiver Operating Characteristic (ROC) analysis and the corresponding Area Under the Curve (AUC) is tested, and a CFI score ≥4 is selected to discriminate patients undergoing surgical management under general anesthesia (Positive Predictive Value, PPV of 91.4%), while a CFI score ≥10 is selected to identify patients undergoing major surgical procedures (Negative Predictive Value, NPV of 91.7%). These results are enhanced by the consensual trend of Length of Stay outcome. The use of the CFI score allows us to distinguish between the "Mild facial trauma" with a low risk of hospitalization for surgical treatment, the "Moderate facial trauma" with a high probability of surgical treatment, and the "Severe facial trauma" that requires long-lasting surgery and hospital stay, with an increased incidence of Intensive Care Unit admission.

Avoiding immediate whole-body trauma CT: a prospective observational study in stable trauma patients.

High energy blunt trauma patients with normal vital signs are usually investigated with a Contrast Enhanced Computed Tomography (CECT) for torso injuries. CECT involves high levels of radiations, often showing no injuries in patients over-triaged to the trauma center. The aim of our study was to suggest an alternative diagnostic protocol based on Emergency Room (ER) tests (physical exam, blood tests, extended FAST, Chest and Pelvis X-ray) to avoid CECT in selected patients. A prospective cohort study was conducted from September 2018 to September 2019. Five hundred patients fulfilled the inclusion criteria. Patients received torso-CECT scan only if they had at least one positive ER test. The validity of the single component of the protocol and the global validity of the ER tests to detect torso injuries was assessed through sensitivity, specificity, positive (PPV) and negative (NPV) predictive value, positive (+ LR) and negative (- LR) likelihood ratio. Multivariate analysis was performed to identify independent predictors of torso injuries. One hundred and seventy patients received a torso-CECT scan because of positive ER tests. ER tests showed a global sensitivity for torso injuries of 86.96% (95% CI 80.17-92.08) specificity of 83.98%(95% CI 79.79-87.60), PPV of 67.42% (95% CI 61.83-72.54), NPV of 94.41% (95% CI 91.63-96.30) + LR of 5.43 (95% CI 4.25-6.93), - LR of 0.16 (95% CI 0.10-0.24). ER tests in an experienced center seem to be able to identify more severe blunt trauma patients needing CECT. Further studies are advisable to confirm these results.

Emergency Management of Pelvic Bleeding.

Pelvic trauma continues to have a high mortality rate despite damage control techniques for bleeding control. The aim of our study was to evaluate how Extra-peritoneal Pelvic Packing (EPP) and Resuscitative Endovascular Balloon Occlusion of the Aorta (REBOA) impact the efficacy on mortality and hemodynamic impact. We retrospectively evaluated patients who sustained blunt trauma, pelvic fracture and hemodynamic instability from 2002 to 2018. We excluded a concomitant severe brain injury, resuscitative thoracotomy, penetrating trauma and age below 14 years old. The study population was divided in EPP and REBOA Zone III group. Propensity score matching was used to adjust baseline differences and then a one-to-one matched analysis was performed. We selected 83 patients, 10 for group: survival rate was higher in EPP group, but not significantly in each outcome we analyzed (24 h, 7 day, overall). EPP had a significant increase in main arterial pressure after procedure (+20.13 mmHg, p < 0.001), but this was not as great as the improvement seen in the REBOA group (+45.10 mmHg, p < 0.001). EPP and REBOA are effective and improve hemodynamic status: both are reasonable first steps in a multidisciplinary management. Zone I REBOA may be useful in patients 'in extremis condition' with multiple sites of torso hemorrhage, particularly those in extremis.

Emergency Department Resuscitative Thoracotomy: Indications, surgical procedure and outcome. A narrative review.

BACKGROUND: Emergency Department Thoracotomy (EDRT) after traumatic Cardio-pulmonary Arrest (CPR) can be used to salvage select critically injured patients. Indications of this surgical procedure are widely debated and changed during last decades. We provide the available literature about EDRT in the effort to provide a comprehensive synthesis about the procedure, likelihood of success and patient's outcome in the different clinical setting, accepted indications and technical details adopted during the procedure for different trauma injuries. METHODS: Literature from 1975 to 2020 was retrieved from multiple databases and reviewed. Indications, contraindications, total number and outcome of patients submitted to EDRT were primary endpoints. RESULTS: A total number of 7236 patients received EDRT, but only 7.8% survived. Penetrating trauma and witnessed cardiopulmonary arrest with the presence of vital signs at the trauma center are the most favorable conditions to perform EDRT. CONCLUSIONS: EDRT should be reserved for acute resuscitation of selected dying trauma patient. Risks of futility, costs, benefits of the surgical procedure should be carefully evaluated before performing the surgical procedure.

Traumatic hollow viscus and mesenteric injury: role of CT and potential diagnostic-therapeutic algorithm.

Despite its rarity, traumatic hollow viscus and mesenteric injury (HVMI) have high mortality and complication rates. There is no consensus regarding its best management. Our aim is to evaluate contrast enhanced CT (ceCT) in the screening of HVMI and its capability to assess the need for surgery. All trauma patients admitted to an urban Level 1 trauma center between 2010 and 2018 were retrospectively evaluated. Patients with ceCT scan prior to laparotomy were included. Patients requiring surgical repair of HVMI and a ceCT scan consistent with HVMI were considered true positives. Six ceCT scan criteria for HVMI were used; at least one criterion was considered positive for HVMI. Sensitivity (Sn), specificity (Sp), predictive values (PV), likelihood ratios (LR) and accuracy (Ac) of ceCT of single ceCT criteria and of the association of ceCT criteria were calculated using intraoperative findings as gold standard. Therapeutic time (TT), death probability (DP), and observed mortality (OM) were described. 114 of 4369 patients were selected for ceCT accuracy analysis; 47 were considered true positives. Sn of ceCT for HVMI was 97.9%, Sp 63.6%, PPV 66.2%, NPV 97.6%, + LR 2.69, -LR 0.03, Ac 78%; no single criterion stood out. The association of four or more criteria improved ceCT Sp to 98.5%, PPV to 95.6%, + LR to 30.5. Median TT was 2 h (IQR: 1-3 h). OM was 7.8%-not significantly higher than overall OM. CeCT in trauma has become a reliable screening test for HVMI and a valid exam to select HVMI patients for surgical exploration.

Epidemiology of trauma admissions in a level 1 trauma center in Northern Italy: a nine-year study.

The aim of this study was to analyze the results of 9 years of trauma care and data collection in a level 1 urban trauma center in Northern Italy. Overall, 6065 patients have been included in the study; the number of patients managed yearly has doubled between 2011 and 2019. This rise mostly involved patients with injury severity score (ISS) < 16. Most injuries (94%) were blunt. Road traffic accidents, especially involving motorcycles, were the most common cause of injury. Self-inflicted injuries were responsible for less than 5% of trauma but they were severe in 56% of cases. The median age was 38 and it remained constant over the years; 43% of patients had 14-39 years of age. Different characteristics and patterns of injury were observed for each age group and gender. Males were more likely to be injured in the central years of life while females presented a trimodal pattern in the age distribution. Young adults (14-39 years old) were overall at higher risk of self-harm. Overall mortality was equal to 5.2%. Most deceased were male and ≥ 65 years of age.

The Malone antegrade continence enema adapting a transanal irrigation system in patients with neurogenic bowel dysfunction.

INTRODUCTION: Patients with severe neurogenic bowel dysfunction (NBD) may undergo the Malone antegrade continence enema (MACE) surgery to perform antegrade bowel irrigation (ABI). The standard approach may be prevented by a previous appendectomy or complicated by appendicular stenoses and/or stomal leakages. We present the experience by our tertiary referral center for NBD, adopting a modified surgical technique, based on a neoappendix with the terminal ileum to preserve the natural anti-reflux mechanism of the ileocecal valve and avoid stool leakage, and a largely available transanal irrigation (TAI) system to catheterize the neoappendix and perform ABI. CASE PRESENTATION: Three individuals with NBD successfully underwent our modified MACE program. Case 1 had cauda equina syndrome. He underwent surgery at 40. Case 2 was a man who suffered from spinal cord dysfunction due to acute disseminated encephalomyelitis, functionally T12 AIS B, at 57. Case 3 was a man with traumatic L1 AIS B paraplegia. At 60 he underwent surgery after 29 years since the injury. He needed a surgical revision due to a postoperative subcutaneous infection. After 121, 84 and 14 months from surgery, the three individuals performed ABI every 2 days, presented functional stomas, had no fecal incontinence, and reported an NBD score of 6, compared to 40, 33 and 35 pre-operatively. DISCUSSION: To our knowledge, this is the first report of MACE combining a tapered terminal ileum conduit and an adapted TAI system. Our approach proved to be a safe and effective strategy for severe NBD avoiding a colostomy.

Impact of the COVID-19 outbreak on severe trauma trends and healthcare system reassessment in Lombardia, Italy: an analysis from the regional trauma registry.

BACKGROUNDS: The COVID-19 pandemic drastically strained the health systems worldwide, obligating the reassessment of how healthcare is delivered. In Lombardia, Italy, a Regional Emergency Committee (REC) was established and the regional health system reorganized, with only three hospitals designated as hubs for trauma care. The aim of this study was to evaluate the effects of this reorganization of regional care, comparing the distribution of patients before and during the COVID-19 outbreak and to describe changes in the epidemiology of severe trauma among the two periods. METHODS: A cohort study was conducted using retrospectively collected data from the Regional Trauma Registry of Lombardia (LTR). We compared the data of trauma patients admitted to three hub hospitals before the COVID-19 outbreak (September 1 to November 19, 2019) with those recorded during the pandemic (February 21 to May 10, 2020) in the same hospitals. Demographic data, level of pre-hospital care (Advanced Life Support-ALS, Basic Life Support-BLS), type of transportation, mechanism of injury (MOI), abbreviated injury score (AIS, 1998 version), injury severity score (ISS), revised trauma score (RTS), and ICU admission and survival outcome of all the patients admitted to the three trauma centers designed as hubs, were reviewed. Screening for COVID-19 was performed with nasopharyngeal swabs, chest ultrasound, and/or computed tomography. RESULTS: During the COVID-19 pandemic, trauma patients admitted to the hubs increased (46.4% vs 28.3%, p < 0.001) with an increase in pre-hospital time (71.8 vs 61.3 min, p < 0.01), while observed in hospital mortality was unaffected. TRISS, ISS, AIS, and ICU admission were similar in both periods. During the COVID-19 outbreak, we observed substantial changes in MOI of severe trauma patients admitted to three hubs, with increases of unintentional (31.9% vs 18.5%, p < 0.05) and intentional falls (8.4% vs 1.2%, p < 0.05), whereas the pandemic restrictions reduced road- related injuries (35.6% vs 60%, p < 0.05). Deaths on scene were significantly increased (17.7% vs 6.8%, p < 0.001). CONCLUSIONS: The COVID-19 outbreak affected the epidemiology of severe trauma patients. An increase in trauma patient admissions to a few designated facilities with high level of care obtained satisfactory results, while COVID-19 patients overwhelmed resources of most other hospitals.

Independent Predictors of Mortality in Torso Trauma Injuries.

Noncompressible torso injuries (NCTIs) represent a trauma-related condition with high lethality. This study's aim was to identify potential prediction factors of mortality in this group of trauma patients at a Level 1 trauma center in Italy. MATERIALS AND METHODS: A total of 777 patients who had sustained a noncompressible torso injury (NCTI) and were admitted to the Niguarda Trauma Center in Milan from 2010 to 2019 were included. Of these, 166 patients with a systolic blood pressure (SBP) <90 mmHg were considered to have a noncompressible torso hemorrhage (NCTH). Demographic data, mechanism of trauma, pre-hospital and in-hospital clinical conditions, diagnostic/therapeutic procedures, and survival outcome were retrospectively recorded. RESULTS: Among the 777 patients, 69% were male and 90.2% sustained a blunt trauma with a median age of 43 years. The comparison between survivors and non-survivors pointed out a significantly lower pre-hospital Glasgow coma scale (GCS) and SBP (p < 0.001) in the latter group. The multivariate backward regression model identified age, pre-hospital GCS and injury severity score (ISS) (p < 0.001), pre-hospital SBP (p = 0.03), emergency department SBP (p = 0.039), performance of torso contrast enhanced computed tomography (CeCT) (p = 0.029), and base excess (BE) (p = 0.008) as independent predictors of mortality. CONCLUSIONS: Torso trauma patients who were hemodynamically unstable in both pre- and in-hospital phases with impaired GCS and BE had a greater risk of death. The detection of independent predictors of mortality allows for the timely identification of a subgroup of patients whose chances of survival are reduced.

Predictive Factors for Massive Transfusion in Trauma: A Novel Clinical Score from an Italian Trauma Center and German Trauma Registry.

Early management of critical bleeding and coagulopathy can improve patient survival. The aim of our study was to identify independent predictors of critical bleeding and to build a clinical score for early risk stratification. A prospective analysis was performed on a cohort of trauma patients with at least one hypotensive episode during pre-hospital (PH) care or in the Emergency Department (ED). Patients who received massive transfusion (MT+) (≥4 blood units during the first hour) were compared to those who did not (MT-). Hemodynamics, Glagow Coma Score (GCS), diagnostics and blood tests were evaluated. Using multivariate analysis, we created and validated a predictive score for MT+ patients. The predictive score was validated on a matched cohort of patients of the German Trauma Registry TR-DGU. One hundred thirty-nine patients were included. Independent predictors of MT+ included a prehospital (PH) GCS of 3, PH administration of tranexamic acid, hypotension and tachycardia upon admission, coagulopathy and injuries with significant bleeding such as limb amputation, hemoperitoneum, pelvic fracture, massive hemothorax. The derived predictive score revealed an area under the curve (AUC) of 0.854. Massive transfusion is essential to damage control resuscitation. Altered GCS, unstable hemodynamics, coagulopathy and bleeding injuries can allow early identification of patients at risk for critical hemorrhage.

Extraperitoneal packing in unstable blunt pelvic trauma: A single-center study.

BACKGROUND: Hemodynamically unstable pelvic fractures often require a multi-modal approach including both operative and endovascular management. While an important adjunct in hemorrhage control, time to angioembolization even at the most advanced trauma centers may take hours. Extraperitoneal packing (EPP) is a fast and effective procedure that can immediately address pelvic hemorrhage from the retroperitoneal space in severe pelvic injuries. The aim of this study was to evaluate the efficacy of early EPP, looking at 24 hours and overall mortality, and the hemodynamic impact of EPP in unstable blunt pelvic trauma. METHODS: All trauma patients admitted to an urban Level I trauma center were evaluated from 2002 to 2018 in a retrospective single-center comparative study. Inclusion criteria were patients 14 years or older who sustained blunt trauma with pelvic fractures and hemodynamic instability. Exclusion criteria were a concomitant head injury (Abbreviated Injury Scale >3) and patients who underwent resuscitative thoracotomy. The patient population was divided into two groups: an EPP group and a no-EPP group. Propensity score matching was used to adjust for differences in baseline characteristics in the two groups: a one-to-one matched analysis using nearest-neighbor matching was performed based on the estimated propensity score of each patient. RESULTS: Two hundred forty-four patients presented hemodynamically unstable, with a pelvic fracture (180 no-EPP, 64 EPP). With propensity score matching, 37 patients in each group were analyzed. Survival within the first 24 hours was significantly improved in the EPP group (81.1% vs. 59.5%, p = 0.042) and we registered similar results in overall survival rate (78.4% EPP group vs. 56.8% no-EPP group, p = 0.047). Those patients who underwent early EPP (n = 64) were associated with a significant improvement in hemodynamic stability, with a pre-EPP mean arterial pressure of 49.9 mm Hg and post-EPP mean arterial pressure of 70.1 mm Hg (p < 0.01). CONCLUSION: Extraperitoneal pelvic packing is an effective procedure that can be performed immediately, even within the trauma bay, to improve hemodynamic stability and overall survival in patients who sustain severe blunt pelvic trauma. The early use of EPP can be lifesaving. LEVEL OF EVIDENCE: Therapeutic, Level III.

Motorcycle-related trauma:effects of age and site of injuries on mortality. A single-center, retrospective study.

BACKGROUND: Motorcyclists are often victims of road traffic incidents. Though elderly patients seem to have worse survival outcomes and sustain more severe injuries than younger patients, concordance in the literature for this does not exist. The aim of the study is to evaluate the impact of age and injury severity on the mortality of patients undergoing motorcycle trauma. METHODS: Data of 1725 patients consecutively admitted to our Trauma Center were selected from 2002 to 2016 and retrospectively analyzed. The sample was divided into three age groups: ≤ 17 years, 18-54 years, and ≥ 55 years. Mortality rates were analyzed for the overall population and patients with Injury Severity Score (ISS) ≥ 25. Differences in survival among age groups were evaluated with log-rank test, and multivariate logistic regression models were created to identify independent predictors of mortality. RESULTS: A lower survival rate was detected in patients older than 55 years (83.6% vs 94.7%, p = 0.049) and in those sustaining critical injuries (ISS ≥ 25, 61% vs 83%, p = 0.021). Age (p = 0.027, OR 1.03), ISS (p < 0.001, OR 1.09), and Revised Trauma Score (RTS) (p < 0.001, OR 0.47) resulted as independent predictors of death. Multivariate analysis identified head (p < 0.001, OR 2.04), chest (p < 0.001, OR 1.54), abdominal (p < 0.001, OR 1.37), and pelvic (p = 0.014, OR 1.26) injuries as independent risk factors related to mortality as well. Compared to the theoretical probability of survival, patients of all age groups showed a survival advantage when managed at a level I trauma center. CONCLUSIONS: We detected anatomical injury distributions and mortality rates among three age groups. Patients aging more than 55 years had an increased risk of death, with a prevalence of severe chest injuries, while younger patients sustained more severe head trauma. Age represented an independent predictor of death. Management of these patients at a level I trauma center may lead to improved outcomes.
