Objective To evaluate the efficacy and safety of early anticoagulation therapy using low-molecular-weight heparin sodium against venous thromboembolism (VTE) in traumatic patients.Methods A total of 120 severely traumatized patients were assigned to convention group (n =60) and anticoagulation group (n =60) according to the random number table.Patients in convention group were given physical therapy against VTE,while in anticoagulation group were given add-on low-molecularweight heparin sodium against VTE once the stopping of blood bleeding was achieved.Safety parameters were recorded including VTE incidence,blood loss indexes,hemorrhage-related complications,incidence of heparin-induced thrombopenia (HIT) and blood coagulation function indicators.Results Thirteen patients presented with VTE,with 10 patients (17％) in convention group versus 3 patients 5％) in anticoagulation group (P ＜ 0.05).Blood loss index in convention group was 1.252 ± 1.033 versus 1.447 ± 1.196 in anticoagulation group;two patients (3％) developed gastrointestinal bleeding in convention group versus five patients (8％) in anticoagulation group;five patients (8％) had wound bleeding in convention group versus eight patients (13％) in anticoagulation group (all P ＞ 0.05).HIT was not noted in anticoagulation group.At the endpoint of evaluation,no significant differences were noted between the two groups with regard to changes in prothrombin time (PT),activated partial thromboplastin time (APTT) and D-dimers (P ＞ 0.05);however,convention group versus anticoagulation group showed significant differences in international normalized ratio (INR) (0.97 ± 0.10 vs.1.03 ±0.17),fibrin (Fib) [(4.85-± 1.37) g/L vs.(4.01 ± 1.16) g/L] and platelet (PLT) [(317.68 ±141.71) ×109/Lvs.(422.20±178.16) ×109/L] (P＜0.05).Conclusion Inthe earlystage of trauma,low-molecular-weight heparin anticoagulation therapy can significantly reduce the incidence of VTE without increasing the risk of bleeding.

Objective To analyze the risk factors of patients with trauma in intensive care unit (ICU), a new warning scoring system is established for predicting the incidence of sepsis in traumatic patients; and to provide a new simple method of clinical score, which could provide a reference for clinical prevention and treatment of sepsis. Methods The clinical data of 591 patients with trauma in the ICU of the Army Specialized Medical Center of Army Medical University and Affiliated Hospital of Zunyi Medical University from January 2012 to December 2017 were retrospectively analyzed. The patients were divided into sepsis group (n = 382) and non-sepsis group (n = 209) according to their clinical outcome. The basic clinical data of all ICU trauma patients were collected, and the differences in gender, age, underlying diseases, and vital signs, critical illness scores, blood culture results and laboratory biochemical examinations within 24 hours of ICU admission between the two groups were analyzed. Univariate Logistic regression analysis was used to screen the related factors leading to sepsis. The indexes with P < 0.12 analyzed by univariate Logistic regression analysis were included in multivariate Logistic regression analysis. The risk factors of sepsis in traumatic patients were screened and assigned, and the total score was sepsis early warning score. The receiver operating characteristic (ROC) curve was plotted to evaluate the predictive value of the warning score of sepsis in patients with trauma. Results The incidence of sepsis in ICU trauma patients was 64.6% (382/591), and the ICU mortality was 10.5% (40/382). The traffic accident was a common cause of ICU trauma patients. Compared with non-sepsis patients, Glasgow coma score (GCS), proportion of past history, red blood cell (RBC), platelet (PLT), albumin (Alb) were lower in patients with sepsis, and body temperature, pulse, acute physiology and chronic health evaluation Ⅱ (APACHEⅡ), sequential organ failure assessment (SOFA), injury severity score (ISS), new injury severity score (NISS), fraction of inspired oxygen (FiO2), blood sodium, activated partial thromboplastin time (APTT), prothrombin time (PT), procalcitonin (PCT), C-reactive protein (CRP) levels were higher, blood transfusion, central venous catheterization, mechanical ventilation, shock, multiple organ dysfunction syndrome (MODS), open injury and multiple injuries were more common, the duration of mechanical ventilation, ICU days and total hospital days were longer, and all the differences were statistically significant. Most of the traumatic patients with sepsis were undergone with multiple trauma. Compared with non-sepsis patients, the proportion of multiple position trauma was significantly higher than patients without sepsis. And most traumatic patients were insulted in head, face and neck. The risk factors were screened by univariate and multivariate Logistic stepwise regression analysis, the indexes into the regression model were pulse > 100 bpm [odds ratio (OR) = 1.617, 95% confidence interval (95%CI) = 0.992-2.635, P = 0.044], APTT > 36 s (OR = 2.164, 95%CI =1.056-4.435, P = 0.035), shock (OR = 1.798, 95%CI = 1.056-3.059, P = 0.031), mechanical ventilation (OR = 5.144, 95%CI = 2.302-11.498, P < 0.001), APACHEⅡ > 21 (OR = 3.348, 95%CI = 1.724-6.502, P < 0.001), NISS > 25 (OR = 3.332, 95%CI = 1.154-9.624, P = 0.026), assigning scores were 0.5, 1.0, 0.5, 1.5, 1.5, 1.5, respectively, which were included in the new warning score of sepsis. ROC curve analysis showed that the area under ROC curve (AUC) of warning score for predicting sepsis in patients with trauma was 0.782, which was significantly higher than the APACHEⅡ(AUC = 0.672), APTT (AUC = 0.574) and NISS (AUC = 0.515) with significant difference (all P < 0.01). When the cut-off value of sepsis warning score was 4.0, the sensitivity and specificity were 71.7% and 61.9%, respectively. Conclusions Close monitoring and stabilization of vital signs of traumatic patients within 24 hours of ICU admission and reduction of unreasonable invasive mechanical ventilation time are expected to reduce the incidence of sepsis in traumatic patients. New warning score of sepsis consisted of six factors: pulse, APTT, shock, mechanical ventilation, APACHEⅡ and NISS. Rational use of warning score of sepsis would help us to assess the prognosis of traumatic patients more easily and effectively, and the predicted effect is much better than APACHEⅡ, APTT and NISS.

A novel coronavirus pneumonia (NCP) epidemic has occurred in Wuhan, Hubei Province since December 2019, caused by a novel coronavirus (2019-nCoV) never been seen previously in human. China has imposed the strictest quarantine and closed management measures in history to control the spreading of the disease. However, severe trauma can still occur in the NCP patients. In order to standardize the emergency treatment and the infection prevention and control of severe trauma patients with hidden infection, suspected or confirmed infection of 2019-nCoV, Trauma Surgery Branch of Chinese Medical Doctors' Association organized this expert consensus. The consensus illustrated the classification of the NCP patients, severe trauma patients in need of emergency surgery, emergency surgery type, hierarchical protection for medical personnel and treatment places. Meanwhile, the consensus standardized the screening, injury severity evaluation, emergency surgical treatment strategy and postoperative management strategy of severe trauma patients during the epidemic period of NCP, providing a basis for the clinical treatment of such kind of patients.
