Objective To evaluate the clinical importance of doublecontrast CTdiagnosis of traumatic anterior shoulder instability. Methods Forty-eight patients underwent double contrast CT scan. With the guide of CT scan, anterior arthrocentesis of the shoulder was performed and 4 ml of 76% urografin was injected into the joint and then 10 ml of filtrated air was injected. The patients wereexamined by SOMATOM CR Systematic CT. The results of double contrast CT of the 48 patients were divided into Ⅰ, Ⅱ and Ⅲ degree according to the CT results related to their injury history, clinical symptoms, signs and operation findings. Results The patients had no complaint after the CT examination exceptfor 3 patients, who had slight pain within 2 days after CT examination. The results of double contrast CT were as follow:Ⅰ degree: 9 patients, Ⅱ degree: 22 patients, and Ⅲ degree: 17 patients. All patients with Ⅰ degree injuries were treated with rehabilitation program. The patients with Ⅱ degree injuries were mainly treated withrehabilitation program, but took much longer time. The patients with Ⅲ degreeinjuries were suggested to be treated with surgery. Conclusion To divide the results of double contrast CT into Ⅰ，Ⅱ and Ⅲ degree not only reflects the severity of traumatic anterior shoulder instability but provides information for the treatment of the instability.
Objective To investigate the short-term effectiveness of Swanson artificial joint replacement in treating post-traumatic metacarpophalangeal joint stiffness. Methods Between August 2007 and May 2010, 11 cases (13 fingers) of metacarpophalangeal joint stiffness with soft tissue defects underwent Swanson artificial joint replacement. There were 7 males (9 fingers) and 4 females (4 fingers), aged 43 to 65 years with an average of 49 years. The involved fingers included 4 thumbs, 4 index fingers, 3 middle fingers, and 2 ring fingers. The types of injury included open and crush injury in 8 fingers, fracture of the metacarpophalangeal joint in 3 fingers, metacarpophalangeal joint severing in 2 fingers. The time from joint stiffness to hospitalization was 12 to 48 weeks (mean, 24 weeks). The joint activity was (136.82 ± 28.96)°. According to total active motion (TAM) assessment, included good in 1 finger, fair in 6 fingers, and poor in 6 fingers before operation. The activities of daily living were assessed by Sollerman score, which was 45.64 ± 11.04. The X-ray films and CT scan showed traumatic arthritis of the metacarpophalangeal joint. Results The incision healed by first intention. All patients were followed up 12 to 34 months (mean, 24.1 months). At last follow-up, the joint activity was (194.64 ± 28.86)°, showing significant difference when compared with preoperative value (t=25.214, P=0.000). According to TAM assessment, including excellent in 1 finger, good in 4 fingers, fair in 7 fingers, and poor in 1 finger. The Sollerman score was 67.45 ± 8.20 postoperatively, showing significant difference when compared with the preoperative score (t=10.470, P=0.000). X-ray examination showed no prosthesis fracture, periprosthetic fracture, or joint dislocation occurred at last follow-up. Conclusion Swanson artificial joint replacement can be appl ied to treat posttraumatic metacarpophalangeal joint stiffness, which can improve the joint activity and has satisfactory short-term effectiveness.
Objective To evaluate the hemostatic effect of selective artery embolization in treatment for traumatic hepatic rupture bleeding. Methods The clinical data of 63 patients with traumatic hepatic rupture treated in this hospital from Jan. 2004 to Jun. 2011 were analyzed retrospectively. With Seldinger technique， a catheter was introduced into the liver artery via the right femoral artery for angiography. Once the bleeding site was identified， microcatheter was placed into the hemorrhagic vessels to control the bleeding with polyvinyl alcohol or gelatin sponges. Results The hepatic arteriography was successfully performed in 63 cases， the results showed hepatic left-artery bleeding in 8 cases， hepatic right-artery bleeding in 39 cases， and hepatic left- and right-artery bleeding in 10 cases. Fifty-seven cases received selective arterial embolization and successful hemostasia， including one embolization in 36 cases， two embolizations in 11 cases， and more than two embolizations in 10 cases. Six patients without obvious hemorrhage didn’t receive selective arterial embolization. There was no bleeding again case and no dead case. The hemoglobin and hematocrit returned to normal in one week after embolization. No hemorrhage or other complications happened during follow-up for 0.5 to 1 year. Conclusion The selective arterial embolization is an effective， safe and minimally invasive method for hemostasia of patients with traumatic hepatic rupture.
In order to preserve more normal tissue in situ in case of severe traumatic rupture of spleen, simultaneous ligation of splenic artery and vein was performed successfully on animals and then was applied for clinic use. The preserved splenic tissue all survivied and functioned well. Patients with severe traumatic rupture of spleen grade Ⅳ-Ⅴ were all cured by ligation of both the splenic artery and vein at the same time.

ObjectiveTo summarize the clinical characteristics of traumatic pancreatitis (TP) after pancreatic trauma and illustrate the experience of specialized treatment. MethodsClinical data of 73 patients with TP treated in our hospital from January 2008 to June 2014 were collected. The pancreatic injury location, grade, and TP pathogenic factors were analyzed, summarized the common problem and the regularity in TP course, and summarized the treatment strategy, methods of surgical intervention, operation key points and difficulties of TP. ResultsThe grade of pancreatic trauma in the all of patients was mainly to levels of 2, 3, and 4, the head of the pancreas injury accounted for 31.5% (23/73), cervical pancreatic body and tail injuries accounted for 68.5% (50/73). Fifty-nine patients were from other hospitals referral. The occurrence of TP peak period was 4-7 days after pancreatic trauma. Pancreatic fistula and uncontrolled peritoneal infection were the treatment difficulty of TP. It's the effective minimally invasive treatment methods for TP that percutaneous catheter drainage, pancreatic duct stent placement, and endoscopic abscess debridement. Forty-two patients with TP needed reoperations, and 19 cases underwent more than 2 times operation. ConclusionsBecause of the condition of TP is complex and changeable, and difficulty to treat, so the early definitive diagnosis and appropriate surgical strategy play a crucial role in the treatment of TP. Besides, professional team of pancreatic surgery has advantages in estimating patients' conditions, selecting and performing surgical interventions.
ObjectiveTo investigate pathological changes of liver and risk factors for hepatic injury after trauma, in order to provide the instructions for clinical liver transplantation and accumulate the pathological data. MethodsWe retrospectively analyzed the clinical data of 142 patients who died after trauma between January 2010 and December 2014. Based on whether the patients had acute liver damage before dying, they were divided into two groups. The observation group had liver damage before dying, while the control group had not. Combined with the details of trauma, clinical data and autopsy results, we statistically analyzed the pathological changes of liver and risk factors for acute liver damage, including age, gender, trauma kind, trauma site, interval between trauma and hospitalization, damage degree, length of hypotension, the use of more than two vasopressors, large amount of blood transfusion, and complication of shock, infection, or underlying diseases. According to injury severity score (ISS) system, the damage degree was divided into mild damage (ISS<16), moderate damage (ISS≥16 and<25), and severe damage (ISS≥25). ResultsAmong the 142 patients, there were 45 in the observation group with varying degrees of liver cell necrosis, among whom there were 8 mild cases, 14 moderate and 23 severe. There were 97 patients in the control group without acute liver damage, and no significant changes were found in their hepatic tissue. Liver damage was not correlated with age, gender, damage kind, damage site, or pre-hospital time (P>0.05), while it was corrected with the degree of damage, time of hypotension (≥0.5 hour), the use of more than two vasopressors, large amount of blood transfusion (2 000 mL/24 hours), and combination of shock, infection, and other disease except for cardiac and pulmonary diseases (P<0.05). ConclusionWhen using donor livers from patients dying from trauma for transplantation, physicians should be alert to the factors discussed previously which can increase the risk of hepatic injury. Biopsy is useful to assess the suitability of donor livers prior to transplantation.
ObjectiveTo explore the risk factors for death within 7 days after admission in trauma patients undergoing surgery under general anesthesia, and provide evidence for predicting the outcomes of those patients and guidance for clinical practices.MethodsThe basic information and perioperative data of trauma patients who underwent surgery under general anesthesia between January 1st 2019 and December 31st 2020 were collected from the Hospital Information System and the Anesthesia Information Management System. Patients who died within 7 days after admission were assigned into the case group and the others were assigned into the control group, and then propensity-score matching method was used based on age, sex, and injury types. Univariate analyses and multivariate binary logistic regression analysis were used to identify the risk factors for death within 7 days after admission in these patients.ResultsThere were 2 532 patients who met the inclusion criteria, of whom 96 patients with missing follow-up information were excluded, and 2 436 patients remained for the study. After propensity-score matching, there were 19 patients in the case group and 95 patients in the control group. The result of multivariate logistic regression analysis showed that the coma state at admission [odds ratio (OR)=9.961, 95% confidence interval (CI) (1.352, 73.363), P=0.024], perioperative body temperature<36℃ [OR=23.052, 95%CI (1.523, 348.897), P=0.024], intraoperative mean arterial pressure<60 mm Hg (1 mm Hg=0.133 kPa) [OR=12.158, 95%CI (1.764, 83.813), P=0.011], serum calcium concentraion<2.0 mmol/L [OR=33.853, 95%CI (2.530, 452.963), P=0.008], and prothrombin time [OR=1.048, 95%CI (1.002, 1.096), P=0.042] increased the risk of death within 7 days after admission.ConclusionThe coma state, coagulopathy, perioperative hypothermia, intraoperative hypotension, and hypocalcemia are 5 independent risk factors for death in trauma patients after surgery under general anesthesia.
Objective To investigate the suicide related factors of the teenagers after trauma and further discuss the prevalence and related factors of suicide idea plan and behavior. Methods Using the general information questionnaire and the Youth Risk Behavior Survey (YRBS) to investigate the primary and secondary students in the nine worst-hit areas in Wenchuan earthquake of 2008, with cluster random sampling and the class as a sampling unit, to extract random 110 primary and middle schools and gather their general information, disaster-related cases and scores of suicide in YRBS. According to the different types of data, we used descriptive statistics,t test,Chi square test and Logistic regression analysis and respectively use single factor analysis and multivariate logistic regression analysis for suicide idea, plan and behavior. Results A total of 7 833 questionnaires were sent out and a total of 7 521 questionnaires were collected and the recovery rate was 96. 02%. Among them, there were 6 875 valid questionnaires (91.41%) and 636 invalid questionnaires. According to the investigation, the prevalence of the primary and secondary students which had seriously considered suicide was 6. 90%, which had a plan to commit suicide was 4.00% and which tried to take over the action of suicide was 2.70%. With general information for the independent variable, logistic regression analysis showed that whether there had seriously considered suicide as the dependent variable: age (OR=1.178, 95%CI 1.098 to 1.178) and changed in family structure after the earthquake (OR=1.360, 95%CI 1.360 to 1.085) were risk factors for post disaster the teenagers with suicide idea; whether there had been plan to commit suicide as the dependent variable: age (OR=1.099, 95%CI 1.050 to 1.150), the history of being buried in ruin (OR=2.155, 95%CI to 1.104 to 4.205) and changed in family structure after the earthquake (OR=1.495, 95%CI 1.128 to 1.981) were risk factors for post disaster the teenagers with suicide plan; whether took over the action of suicide as the dependent variable: male (OR=1.513, 95%CI 1.122 to 2.039) and changed in family structure after the earthquake (OR=1.555, 95%CI 1.112 to 2.175) were risk factors for post disaster the teenagers with suicide behavior. Conclusion Age and changed in family structure after the earthquake were the risk factors for suicide idea and age was positively correlated with suicidal idea. Age, had the history of being buried in ruin and changed in family structure after the earthquake were the risk factors for suicide plan and age was positively associated with suicide plan. Male and changed in family structure after the earthquake were the risk factors for suicide behavior. Among them, changed in family structure after the earthquake was the common risk factor. So there should be targeted psychological assessment and psychological rehabilitation intervention to avoid the risk of suicide among the teenagers after the disaster.
