Objective:Efficacy of prothrombin complex concentration (PCC) and analysis of prognostic factors in patients with traumatic trauma-induced coagulopathy (TIC).Methods:A retrospective study was conducted on patients with TIC admitted to 11 hospitals from January to December 2021. The data included baseline characteristics, injury information, blood product transfusions (including PCC treatment), laboratory examination at admission and 24 hour-after admission, treatment measure, pre-hospitalization time, and clinical outcomes (improvement at discharge, length of hospital stay). The patients were divided into a conventional group and a PCC group according to whether they were treated with PCC. Propensity score matching method was used to match the patients at a 1:1 ratio, and the differences in different indicators between the groups were compared. Univariate and multivariate logistic regression analyses were performed to identify prognostic factors for TIC patients.Results:After propensity score matching, 103 patients were identified in both the PCC and conventional groups. Univariate logistic regression analysis revealed no significant differences in age, gender, Glasgow Coma Scale (GCS) score, injury severity score, acute physiology and chronic health evaluation score, underlying diseases, pre-hospitalization time, injury type and site, and treatment measure (use of vasoactive drugs, calcium agents, tranexamic acid, and emergency surgery) between the two groups (all P>0.05). Compared with the conventional group, the PCC group exhibited lower 24-hour white blood cell counts, lactate level, prothrombin time, and international normalized ratio (INR) (all P<0.05), whereas hemoglobin level and pH value were higher (both P<0.05). The PCC group also had a shorter hospital stay (13 d vs. 15 d, P<0.05). However, there was no significant difference in the rate of improvement at discharge between the two groups ( P=0.308). Multivariate logistic regression revealed that age (>68 years), GCS score (<5 points), fibrinogen (FIB) level (after 24 h, <2.04 g/L), and INR (after 24 h, >1.455) were independent risk factors affecting the prognosis of TIC patients, and the AUCs were 0.632, 0.702, 0.733, and 0.752, respectively. Conclusions:Treatment with PCC in TIC patients can correct coagulation dysfunction and reduce hospital stay. Age, GCS score, FIB level and INR after 24 h affect the clinical prognosis of TIC patients, which requires special attention.

Objective To assess the clinical value of a novel surgical technique—Tubeless subxiphoid uniportal video-assisted thoracoscopic surgery with percutaneous suspension technique via balance-shaped sternal elevation device in the resection of anterior mediastinal masses. Methods Patients who underwent tubeless subxiphoid uniportal video-assisted thoracoscopic surgery via balance-shaped sternal elevation device in anterior mediastinal masses process at the Department of Thoracic Surgery, West China Hospital, Sichuan University from March to April 2025 were included, and their clinical data were analyzed. Results A total of 4 patients were included, with 2 males and 2 females, aged 58-75 years. The diameter of the tumor was 2.5-3.0 cm. The operation time was 60.0-150.0 min, intraoperative blood loss was 5-10 mL, pain score on the 3rd day after surgery was 0 points, and postoperative hospital stay was 2-3 days. All patients achieved complete resection of the masses and thymus without perioperative complications. Conclusion The tubeless subxiphoid uniportal video-assisted thoracoscopic surgery with percutaneous suspension technique via balance-shaped sternal elevation device technique optimizes surgical visualization and instrument maneuverability while avoiding complications related to conventional anesthesia and tubing, thereby markedly enhancing the minimally invasive profile of anterior mediastinal masses resections. In addition to maintaining procedural safety, this approach effectively reduces postoperative pain and accelerates patient recovery, highlighting its potential for widespread clinical adoption.

BACKGROUND:Trauma-induced coagulopathy(TIC)due to serious injuries significantly leads to increased mortality and morbidity among elderly patients.However,the risk factors of TIC are not well elucidated.This study aimed to explore the risk factors of TIC in elderly patients who have major trauma. METHODS:In this retrospective study,the risk factors for TIC in elderly trauma patients at a single trauma center were investigated between January 2015 and September 2020.The demographic information including gender,age,trauma parts,injury severity,use of blood products,use of vasopressors,need of emergency surgery,duration of mechanical ventilation,length of stay in the intensive care unit(ICU)and hospital,and clinical outcomes were extracted from electric medical records.Multivariate logistic regression analysis was performed to differentiate risk factors,and the performance of the model was evaluated using receiver operating characteristics(ROC)curves. RESULTS:Among the 371 elderly trauma patients,248(66.8%)were male,with the age of 72.5±6.8 years,median injury severity score(ISS)of 24(IQR:17-29),and Glasgow coma score(GCS)of 14(IQR:7-15).Of these patients,129(34.8%)were diagnosed with TIC,whereas 242(65.2%)were diagnosed with non-TIC.The severity scores such as ISS(25[20-34]vs.21[16-29],P<0.001)and shock index(SI),(0.90±0.66 vs.0.58±0.18,P<0.001)was significantly higher in the TIC group than in the non-TIC group.Serum calcium levels(1.97±0.19 mmol/L vs.2.15±0.16 mmol/L,P<0.001),fibrinogen levels(1.7±0.8 g/L vs.2.8±0.9 g/L,P<0.001),and base excess(BE,-4.9±4.6 mmol/L vs.-1.2±3.1 mmol/L,P<0.001)were significantly lower in the TIC group than in the non-TIC group.Multivariate logistic regression analysis revealed that ISS>16(OR:3.404,95%CI:1.471-7.880;P=0.004),SI>1(OR:5.641,95%CI:1.700-18.719;P=0.005),low BE(OR:0.868,95%CI:0.760-0.991;P=0.037),hypocalcemia(OR:0.060,95%CI:0.009-0.392;P=0.003),and hypofibrinogenemia(OR:0.266,95%CI:0.168-0.419;P<0.001)were independent risk factors for TIC in elderly trauma patients.The AUC of the prediction model included all these risk factors was 0.887(95%CI:0.851-0.923)with a sensitivity and specificity of 83.6%and 82.6%,respectively. CONCLUSION:Higher ISS(more than 16),higher SI(more than 1),acidosis,hypocalcemia,and hypofibrinogenemia emerged as independent risk factors for TIC in elderly trauma patients.
