ABSTRACT

Traumatic rib fractures are the most common injury in thoracic trauma. Previously,the patients with traumatic rib fractures were mostly treated non-surgically,of which 50%,especially those combined with flail chest presented chronic pain or chest wall deformities and over 30% had long-term disabilities,being unable to retain a full-time job. In the past two decades,thanks to the development of internal fixation material technology,the surgical treatment of rib fractures has achieved good outcomes. However,there are still some problems in clinical treatment,including inconsistency in surgical treatment and quality control in medical services. The current consensuses on the management of regional traumatic rib fractures published at home and abroad mainly focus on the guidance of the overall treatment decisions and plans,and relevant clinical guidelines abroad lacks progress in surgical treatment of rib fractures in recent years. Therefore,the Chinese Society of Traumatology affiliated to Chinese Medical Association and Chinese College of Trauma Surgeons affiliated to Chinese Medical Doctor Association,in conjunction with national multidisciplinary experts,formulate the Chinese Consensus for Surgical Treatment of Traumatic Rib Fractures(2021)following the principle of evidence-based medicine,scientific nature and practicality. This expert consensus puts forward some clear,applicable,and graded recommendations from aspects of preoperative imaging evaluation,surgical indications,timing of surgery,surgical methods,rib fracture sites for surgical fixation,internal fixation methods and material selections,treatment of combined injuries in rib fractures,in order to provide references for surgical treatment of traumatic rib fractures.

ABSTRACT

Objective:To investigate the use of discriminant analysis to predict the risk of nosocomial mortality in patients with traumatic hemorrhagic shock.Methods:The clinical data of 238 patients with traumatic hemorrhagic shock admitted to Peking University People's Hospital from Sep 2013 to Aug 2020 were retrospectively analyzed. Patients were divided into survival group (214 cases) and death group (24 cases). Stepwise discriminant analysis was used to establish a discriminant model.Results:The difference of history of stroke (9.8% vs. 25.0%), main site of bleeding (extremities)(58.9% vs. 29.2%), APACHEⅡ score (16.4±5.1 vs. 23.2±6.1), blood lactic acid [2.1(1.1-3.5) mmol/L vs. 4.9(2.0-13.4) mmol/L] and surgery (92.5% vs. 58.3%) between the two groups was all statistically significant (all P<0.05). Finally, There are five indicators that entered the discriminant model: history of stroke, main site of bleeding (extremities), blood lactic acid, APACHE Ⅱ score and surgery. The area under the ROC curve for predicting the risk of mortality in patients with traumatic hemorrhagic shock was 0.857, 95% CI 0.754-0.959. Conclusions:The established discriminant model has a high accuracy in predicting the risk of in-hospital mortality in patients with traumatic hemorrhagic shock.

ABSTRACT

Objective:To investigate the ability of doctors in different regions and levels of hospitals in assessing the severity of severe trauma in China.Methods:A total of 38 trauma centers of China Trauma Rescue & Treatment Association (19 tertiary hospitals and 19 secondary hospitals, including 20 eastern and 18 western hospitals) were selected from November 2018 to May 2020. Two junior, two middle, and two senior emergency surgeons were selected in each center. Injury severity score (ISS) was performed on 10 patients with severe trauma, and the qualified rate was analyzed.Results:The qualified rates of junior, middle, and senior doctors were 56.05%, 56.18%, and 56.71%, respectively ( P>0.05). The qualified rates of tertiary and secondary hospitals were 63.07% and 49.56%, respectively ( P<0.01). The qualified rates of eastern and western hospitals were 67.00% and 44.44%, respectively ( P<0.01). Conclusions:The overall level of injury assessment of severe trauma patients by doctors in China is satisfactory, while there are still differences in hospital levels and regions. In the future, attention should be paid to the training and system construction in primary hospitals. We should actively support the construction and development of hospitals in the western regions and realize the standardization of trauma treatment in China as soon as possible.

ABSTRACT

Objective:To establish a rat model of volume-controlled hemorrhage and observe the pathophysiological changes that ensued.Methods:Sprague Dawley (SD) rats were subjected to femoral arterial cannulation and hemorrhage for 40% or 50% of total volume. The hemodynamics data and arterial blood gas were collected, and survival after hemorrhage was monitored for 24 hours ( n=8/group). Then lung, liver, intestine and kidney were collected for HE staining after 40% hemorrhage at 4, 8 and 12 hours ( n=6/group). Results:Mean arterial pressure of 40% and 50% blood loss group decreased significantly from (90±5)mmHg and (93±4)mmHg to (40±4)mmHg and (34±4)mmHg ( P<0.05). Heart rate of 40% and 50% blood loss group increased significantly from (330±35) bpm and (336±32) bpm to (478±36) bpm and (490±21) bpm ( P<0.05). Hemoglobin and pH decreased significantly following hemorrhage, while lactate increased. The survival rate of 50% blood loss group was just 12.5% and 40% blood loss group was 100% ( P<0.05). Compared with sham group, the most significant injury was observed in lung and small intestine after 4 hours, in liver after 8 hours and in kidney after 12 hours following hemorrhage. Conclusion:This study established a stable and repeatable volume-controlled hemorrhagic shock model in rat.

ABSTRACT

Objective:To evaluate the trauma center model in general hospitals for patients with severe trauma.Methods:The data of 1,248 patients with severe trauma (ISS≥16) were retrospectively analyzed who had been admitted to the trauma centers in 6 Chinese general hospitals from January 2019 through June 2020. They were 987 males and 261 females with an age of 50.4 years ± 15.4 years. Their injuries were caused by a traffic accident in 622 cases, falling from a height in 357 cases, a knife in 62 cases, and others (like a heavy object and fall) in 207 cases. Upon admission, their injury severity scores (ISS) were 24.9±8.5 and their Glasgow coma scores (GCS) 12.6±3.6. They were all treated in a scientific and standard manner by a multidisciplinary team at the trauma center of their specific general hospital. Recorded were deaths within 30 days after admission, 30-day mortality and causes of death.Results:All the patients were treated effectively. 101 deaths occurred within 30 days after admission, yielding a 30-day mortality of 8.1%. The main causes of death were severe craniocerebral injury in 56 cases, hemorrhagic shock in 26 cases, multi-organ failure in 11 cases and others in 8 cases.Conclusions:Establishment of trauma centers in China can make up for the disadvantage of over-division of clinical specialties in large general hospitals which has led to insufficient care for patients with severe trauma and multiple injuries. The trauma centers in general hospitals may be a feasible model to be popularized in treatment of patients with severe trauma and multiple injuries.

ABSTRACT

Hemorrhagic shock is hypovolemic shock caused by various blood loss which results in tissue and organ hypoperfusion. Accompanied by coagulation dysfunction, hypothermia, acidosis, inflammatory response and hemorrhagic shock can lead to multiple organ dysfunction syndrome and even be life-threatening. Lung is usually the most vulnerable organ and the first organ showing symptoms during hemorrhagic shock. Acute respiratory distress syndrome (ARDS) has a mortality rate around 40% following acute lung injury (ALI). Hemorrhagic shock-induced ALI/ARDS involves a series of pathophysiological processes, such as insufficient blood perfusion, cell damage, recruitment and infiltration of inflammatory cells and cytokine releasing. However, the underlying mechanisms are not yet completely clear. Based on the pulmonary endothelial and epithelial injury, inflammatory cell recruitment, and inflammatory response, the authors mainly review the recent advances in mechanisms of hemorrhagic shock-induced ALI/ARDS to provide references for clinical treatment and researches.

ABSTRACT

Objective:To investigate the characteristics and perioperative management of hemophilia patients with fracture.Methods:Retrospectively, we analyzed 8 patients with hemophilia combined with fracture, who were admittted to our department from 2005 to 2013.Six patients were with hemophilia A and two with hemophilia B;Based on the severity of hemophilia, 2 cases were light, 3 moderate and 3 severe;Based on the location of fracture, 4 cases were femoral neck fractures, 1 femoral intertrochanteric fracture, 1 bilateral distal femur fractures, 1 tibiofibula fracture, and 1 humerus intercondylar fracture. Blood coagulation factor replacement therapy was conducted preoperatively, intraoperatively and postoper-atively, All the patients underwent closed or open reduction and internal fixation or joint replacement. Also, we analyzed the perioperative complications and observed whether the fracture healed.Results:The average age was 33.5 years (14 to 47 years); In 6 cases, fractures occurred at femur, accounting for 75%of all the fractures; Femoral neck fracture was treated by closed reduction and hollow screws fixation;Femoral intertrochanteric fracture, distal femur fracture, and tibiofibula fracture were treated by open reduction and internal fixation with plate;Humerus intercondylar fracture was treated by elbow joint replacement.Intraoperative bleeding was from 50 to 600 mL, an average of 262 mL;Perioperatively, the average use of FⅧ/activated prothrombin complex concentrates ( APCC) was 358 U/kg (125 to 554 U/kg) .Postoperatively, poor wound healing was observed in 2 patients, and the condition improved after symptomatic treatment; In patients with internal fixation, all the fractures united, and the average hea ling time was 14 weeks.No complications such as fixation loosening or rupture occurred after internal fixation.Conclusion:Hemophilia combined with fracture mainly occurred in the young, and the site of fracture was given priority to femur.With perfect preoperative preparation, on the basis of the replace-ment therapy, hemophilia combined with fractures was safe for surgical treatment, and postoperative frac-tures healing wasgood.But the risk of poor wound healing was high.

ABSTRACT

SUMMARY Trauma is a global social problem, with the number of deaths up to 5.8 million all over the world annually.Currently, severe trauma has become the first cause of death in young adults in China. Nowadays, there are many problems in the trauma rescue system, including long pre-hospital transfer pe-riod , several secondary transfers, no information exchange between pre-hospital and in-hospital care, and the poor integrated treatment, which results in the situation that the overall treatment level of severe trau -ma in China is relatively low.In order to solve these problems, we carried out the research and promotion of severe trauma rescue standard, involving completing severe trauma information database , providing lo-cal rescue medical workers with standard training , and building up the information system for the linkage and warning of severe trauma.In addition, we developed and promoted the new standard system for se -vere trauma in 15cities with 124 medical centers.Due to our research, the treatment ability of severe trauma in the pilot areas was enhanced, and the mortality and morbidity of severe trauma were reduced significantly.To sum up, we had got the expected results after implementing the project .

ABSTRACT

Objective:To apply modified proximal femoral nail anti-rotation ( PFNA ) fixation tech-niques performed by percutaneous placement of guide wire combined with true lateral view and to make the procedures simpler.Methods:A retrospective study was used to analyze the clinical data of femoral intertrochanteric fractures cases, which were treated with conventional PFNA fixation or modified PFNA fixation performed by percutaneous placement guide wire combined with true lateral view in our hospital, from March, 2011 to May, 2014.In the study, 60 cases were followed for average 13 months.The oper-ation time, the amount of bleeding, the fluoroscopy time, postoperative radiographic measurements ( tip apex distance, TAD ) and hip function scores were analyzed.Results:In modified PFNA group, the amount of bleeding, the operation time and the fluoroscopy time were (70.5 ±12.5) min, (34.9 ±6.1) mL, ( 63.6 ±9.7 ) s respectively.In conventional PFNA group, they were ( 80.6 ±17.1 ) min, (47.8 ±6.7) mL, (68.5 ±8.7) s respectively.There were significant differences in the above respects between the two groups (P were 0.006, 0.013, and 0.022 respectively).There were no significant differences in TAD, fracture healing time, postoperative hip scores between the two groups (P>0.05). Conclusion:Fracture line is a natural entry point for some cases of femoral intertrochanteric fractures when we use proximal femoral nail anti-rotation to fix the fracture.Applying percutaneous insertion of the guide pin combined with true lateral view could reduce the operation time, amount of bleeding, and fluo-roscopy time significantly, make the procedures simpler and acquire satisfactory results .

ABSTRACT

Objective To evaluate the clinical efficacy of Achillon,a novel guide for Achilles tendon suture produced by Newdeal Ltd in France,in the mini-invasive surgical treatment of acute Achilles tendon rupture. Methods Between December 2010 and March 2011,7 patients(7 feet) with acute Achilles tendon rupture were treated in our department.They were 5 males (5 feet) and 2 females (2 feet),with an average age of 34.2 years (range,21 to 53 years).The interval between injury and operation ranged from 1 to 11 days(3.8 days on average).A longitudinal incision approximately 2.0-3.5 cm in length was made around the ruptured Achilles tendon for minimally invasive repair after insertion of the Achillon.Postoperative rehabilitation was carried out. Results All the wounds healed at the first stage.All patients were followed up for 5 to 11 months, with an average of 7.2 months. All patients regained normal weight-bearing walking 3 months after operation without any re-rupture. According to the ankle-hindfoot scoring system of American Orthopaedic Foot and Ankle Society (AOFAS),they scored 93.2 points.By the visual analogue scale(VAS),they scored 1.2 points at the operation site. Conclusion The surgical treatment of acute Achilles tendon rupture with Achillon has advantages of mini-invasion,a low rate of incision problems and quick function recovery.

ABSTRACT

Objective To analyze the injury characteristics in 2004-2009 road traffic accidents (RTAS) of 0-25 years old adolescents treated in Beijing 120 Emergency Center so as to provide scientific basis for making effective measures in prevention and control of RTAs. Methods The data of all the adolescents with traffic injuries treated in Beijing 120 Medical Emergency Center were collected for a retrospective analysis on sex,age,traffic injury time,wound regions,injury characteristics and death condition of the injured adolescents. Results( 1 ) There were 17 232 injuries and 259 deaths according to the traffic reports from 2004 to 2009. Among the total injury cases,there were 4 229 cases of 0-25 years old adolescents (24.5%),at (20.13 ± 4.43 ) years of age.The injury number showed a significant rising trend with the increase of age and the injury number of 20 years old group were obvious more than that of other age groups.(2) There were 2 252 males and 1 677 females,with ratio of males to females for 1.5:1 ( P < 0.05 ).( 3 ) Total number of patients was decreased yearly.The high incidence of adolescent RTAs could be seen in September,October and May in one year; Friday,Saturday and Sunday in one week; and between 8:00 am and 11:00 pm in one day.The low incidence of adolescent RTAs could be seen in Tuesday in one week,and 3:00-6:00 am in one day (P <0.05).(4) Cases of limb and arthrosis wounds (53.4%) were more than those of head and neck wounds (35%).Most of the cases were pedestrians (49.1% ).(5) There were 38 deaths,including 28 males and 10 females,at ageof (19.29 ± 5.30) years.The death were mainly resulted from craniocerebral injuries (87%),which mainly concentrated in July ( 13.2% ) and August ( 15.8% ). Conclusions The present condition ofadolescent traffic injuries is not good enough.We should strengthen traffic security education,increase executive powers in the traffic rush and promote cooperation and communication in pre-hospital emergency,as may be beneficial for decreasing adolescent RTA.

ABSTRACT

Objective To analyze the varus deformity of caput humeri and its correlation with fuuctional outcome of unstable proximal humeral fracture managed with locking plate.Methods The study involved 62 patients (24 males and 38 females,at age range of 32-83 years,mean 63.7 years)with proximal humeral fracture who were treated by open reduction and locking plate internal fixation from May 2008 to June 2010 and had full follow-up data.According to Neer classification,there were 11 patients with two parts fractures,41 with three parts fractures,five with four parts fractures and five with dislocation.Their clinical results were evaluated with Constant-Murley scores.ResultsThe mean duration of follow-up was 20.3 months (range,14-37 months),which showed fracture healing in all the patients.There were 11 patients with varus deformity of the caput humeri. The significant difference was found in Constant-Murley score of shoulder function ( P =0.045 ),forward elevation ( P =0.006 ) and abduction (P =0.022) between the varus and non-varus groups.But there was no significant difference in shoulder external rotation( P =0.08 ).The fracture types ( P =0.037 ) and varus deformity of caput humeri ( P =0.006) were closely correlated with the shoulder function between two groups.ConclusionsThe varus deformity of caput humeri mav be predictive factor for poor outcome of the unstable proximal humeral fracture. Restoration of humeral head-shaft alignment and sound reduction should be done as possible during operation.
