RESUMO
BACKGROUND: Venous thromboembolism (VTE), including deep venous thrombosis (DVT) and pulmonary embolism (PE), is a common complication of major trauma. Pharmacological VTE prophylactics are widely used, and low-molecular-weight heparin (LMWH) is recommended. Factor Xa inhibitors are increasingly being used for VTE prophylaxis in both medical and surgical patients. Evidence comparing LMWH and factor Xa inhibitors as VTE prophylactics for severe blunt trauma is lacking. This study aims to compare the efficacy and safety of factor Xa inhibitors and LMHW in VTE prophylaxis. MATERIALS AND METHODS: Patients with severe blunt trauma who received LMWH or a factor Xa inhibitor for VTE prophylaxis in the Trauma Quality Improvement Program between 2017 and 2019 were included. The comparison was performed after using propensity score matching. The outcomes included mortality and incidence of DVT, PE, post-prophylactics haemorrhage control procedures and length of stay. RESULTS: After 2:1 propensity score matching, 1128 patients ( n =752, LMHW group; n =376, factor Xa inhibitor group) were included in the analysis. Patients in the LMWH group had fewer VTE events than those in the factor Xa inhibitor group (DVT, 3.7% vs. 7.2%, P =0.013; PE, 0.4% vs. 3.2%, P <0.001). VTE risk was higher in the factor Xa group (DVT: odds ratio, 1.97; 95% CI, 1.12-3.44; P =0.018 and PE: odds ratio, 9.65; 95% CI, 2.91-44.12; P =0.001). The mortality rate was higher in the LMWH group; however, there was no significant difference (4.0% vs. 1.9%; P =0.075). The difference in the risk of undergoing haemorrhage control surgery after VTE prophylaxis between both groups was insignificant (0.3% vs. 0.0%; P =0.333). CONCLUSIONS: LMWH was associated with a lower risk of VTE than factor Xa inhibitors in patients with severe blunt trauma. The mortality rate was higher in the LMWH group; however, there was no statistically significant difference observed.

INTRODUCTION: The optimal time to intramedullary internal fixation for patients with isolated and unilateral femoral shaft fractures was investigated by the American College of Surgeons-Trauma Quality Improvement Program (ACS-TQIP). MATERIAL AND METHODS: Adult patients from the TQIP between 2017 and 2019 were eligible for inclusion. The associations between time to fixation and target outcomes (pulmonary embolism [PE], deep vein thrombosis [DVT], acute respiratory distress syndrome [ARDS], and mortality) were assessed. Maximization of the sum of sensitivity and specificity was used to determine the optimal cut point. The patients were divided into three groups according to different time to fixation intervals. A multinomial propensity scores weighting using generalized boosted models was performed for all unbiased pre-treatment factors between the groups. Multivariate logistic regression was used to clarify the outcomes predictors. RESULTS: The univariate and multivariate analysis before weighting showed that only PE was significantly associated with time to fixation (odds ratio [OR], 1.05; 95% confidence interval [CI], 1.01-1.09; p = 0.012). The optimal cut point of time to fixation was 13.88 h. The patients were divided into accelerated (≤ 13.88 h), standard (> 13.88 and ≤ 24 h), and delayed (> 24 and < 36 h) groups. After weighting for all unbiased pre-treatment factors between the groups, multivariate logistic regression showed that standard group significantly increased the risk of PE compared with accelerated group (OR, 4.436; 95% CI, 1.844-10.672; p = 0.001). CONCLUSION: Accelerated intramedullary internal fixation within 13.88 h was associated with a significantly decreased risk of PE compared with standard fixation in patients with isolated and unilateral femoral shaft fractures without additional mortality risks.

INTRODUCTION: Contrast-enhanced computed tomography (CT) scans are usually needed in the emergency department (ED) to evaluate intra-abdominal injuries associated with pelvic fractures. Three-dimensional (3-D) images for pelvis reconstruction are also needed for planning surgical fixation after admission. This study investigates the advantages integrating a one-stage computed tomography (CT) scan with these two diagnostic modalities simultaneously to reduce the time to surgery and improve the outcomes of pelvic fracture fixation. METHODS: A retrospective cohort study (2018-2021) of patients with pelvic fractures was performed. Patients were categorized into the one-stage CT group or the two-stage CT group, and propensity score matching was used to address biases. The outcome measures included time to surgical fixation, time to CT scan for 3-D pelvis reconstruction, and overall length of hospital stay. RESULTS: Four hundred forty-four pelvic fracture patients who underwent definite surgical fixation were identified. Of those, 320 underwent a one-stage CT scan, while the remaining 124 underwent a two-stage CT scan. After well-balanced matching, those in the one-stage CT group had a significantly shorter time to surgical fixation than those in the two-stage CT group (4.6 vs. 6.8 days, p < 0.001). Even among critically ill patients necessitating intensive care unit (ICU) admission, the one-stage CT scan group had a shorter time to definitive surgical fixation (5.5 vs. 7.2 days, p = 0.002) and a shorter hospital stay (19.0 vs. 32.7 days, p = 0.006). CONCLUSION: A one-stage contrast-enhanced CT scan combined with simultaneous 3-D pelvis reconstruction is promising for expediting surgical fixation in pelvic fracture patients. This innovative strategy may improve patient outcomes by facilitating timely surgical interventions and minimizing delays associated with additional CT scans.

BACKGROUND/OBJECTIVE: The present study investigated the impact of splenomegaly on the treatment outcomes of blunt splenic injury patients. METHODS: All blunt splenic injury patients were enrolled between 2010 and 2018. The exclusion criteria were age less than 18 years, missing data, and splenectomy performed at another hospital. The patients were divided into two groups based on the presence of splenomegaly, defined as a spleen length over 9.76 cm on axial computed tomography. The primary outcome was the need for hemostatic interventions. RESULTS: A total of 535 patients were included. Patients with splenomegaly had more high-grade splenic injuries (p = 0.007). Hemostatic treatments (p < 0.001) and transarterial embolization (p = 0.003) were more frequently required for patients with splenomegaly. Multivariate analysis showed that male sex (p = 0.023), more packed red blood cell transfusions (p = 0.001), splenomegaly (p = 0.019) and grade 3-5 splenic injury (p < 0.001) were predictors of hemostatic treatment. The failure rate of transarterial embolization was not significantly different between the two groups (p = 0.180). The sensitivity and specificity for splenomegaly in predicting hemostatic procedures were 48.8% and 66.5%, respectively. The positive and negative predictive values were 62.8% and 52.9%, respectively. The overall mortality rate was 3.7%. CONCLUSION: Splenomegaly is an independent predictor for the requirement of hemostatic treatments in blunt splenic injury patients, especially transarterial embolization. Transarterial embolization is as effective for blunt splenic injury patients with splenomegaly as it is for those with a normal spleen.

BACKGROUND: Rib fractures are the most common thoracic injury in patients who sustained blunt trauma, and potentially life-threatening associated injuries are prevalent. Multi-disciplinary work-up is crucial to achieving a comprehensive understanding of these patients. The present study demonstrated the experience of an acute care surgery (ACS) model for rib fracture management from a single level I trauma center over 13 years. METHODS: Data from patients diagnosed with acute rib fractures from January 2008 to December 2020 were collected from the trauma registry of Chang Gung Memorial Hospital (CGMH). Information, including patient age, sex, injury mechanism, Abbreviated Injury Scale (AIS) in different anatomic regions, injury severity score (ISS), index admission department, intensive care unit (ICU) length of stay (LOS), total admission LOS, mortality, and other characteristics of multiple rib fracture, were analyzed. Patients who received surgical stabilization of rib fractures (SSRF) were analyzed separately, and basic demographics and clinical outcomes were compared between acute care and thoracic surgeons. RESULTS: A total of 5103 patients diagnosed with acute rib fracture were admitted via the emergency department (ED) of CGMH in the 13-year study period. The Department of Trauma and Emergency Surgery (TR) received the most patients (70.8%), and the Department of Cardiovascular and Thoracic Surgery (CTS) received only 3.1% of the total patients. SSRF was initiated in 2017, and TR performed fixation for 141 patients, while CTS operated for 16 patients. The basic demographics were similar between the two groups, and no significant differences were noted in the outcomes, including LOS, LCU LOS, length of indwelling chest tube, or complications. There was only one mortality in all SSRF patients, and the patient was from the CTS group. CONCLUSIONS: Acute care surgeons provided good-quality care to rib fracture patients, whether SSRF or non-SSRF. Acute care surgeons also safely performed SSRF. Therefore, we propose that the ACS model may be an option for rib fracture management, depending on the deployment of staff in each institute.

BACKGROUND: Conventionally, pelvic fracture-related acute retroperitoneal hemorrhage (ARH) is life threatening and difficult to control. However, the use of angioembolization to treat fracture-associated ARH improves the hemodynamic stability of patients with pelvic fractures. The role of angioembolization in the management of patients with pelvic fracture-related ARH was examined. MATERIALS AND METHODS: We retrospectively reviewed a large case series of patients with pelvic fractures between January 2010 and December 2014. Comparisons were made between patients with and without ARH. In addition, the characteristics of mortality were delineated, whereas the causes of death in patients with pelvic fracture were discussed and analyzed. RESULTS: A total of 1070 patient records were reviewed during the 60-month study period, and the overall mortality rate of pelvic fracture was 7.7% (82/1070). However, there were only seven patients who died due to uncontrolled ARH (0.7%). The patients with ARH had more injuries to other organs than did the patients without ARH (head: 79.7% vs. 31.7%, pâ¯<â¯0.001; chest: 50.3% vs. 10.9%, pâ¯<â¯0.001; abdomen: 72.0% vs. 22.7%, pâ¯<â¯0.001; spine: 12.6% vs. 4.4%, pâ¯<â¯0.001; extremities: 69.2% vs. 44.3%, pâ¯<â¯0.001). CONCLUSION: The treatment for pelvic fracture patients declared dead upon arrival remains limited. However, pelvic fracture-related ARH could be controlled effectively with angioembolization. In addition to ARH, injuries to other organs may play a key role in the mortality of patients with pelvic fractures.
