Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

War injuries often present as gunshot wounds, penetrating injuries, combined injuries involving multiple body cavities and complex trauma, characterized by high complexity and urgency, which pose a direct threat to the lives of the wounded. Damage control operation (DCO) is crucial for the successful management of severe war trauma and injury and serves as the foundation for achieving the goal of resuscitation. Enhancing surgical competence in early war injury care is vital for improving the medical support capacity in military operations. However, due to the lack of war injury care experience, the DCO competence of most military surgeons is not strong enough, which may lead to reduced treatment efficiency during wartime. Based on the injury care experience in the 21st-century combats, the authors overviewed DCO, highlighted the differences between DCO in peacetime and wartime, and explored the key points and common practices in implementing DCO for war injuries. It was proposed that only by performing DCO in accordance with the principles of war injury care within the golden hour, combined with damage control resuscitation (DCR), a "coordinated approach of surgery and resuscitation", can the rescue level of war injury be improved.

As a platform to display the research achievements in traumatology in China, Chinese Journal of Trauma takes the responsibility of being a good storyteller. In 2002, the journal has made a series of attempts in organizing research on traumatology discipline system, advocating innovative ideas, soliciting contributions based on current affairs and clinical focus or difficult issues, strictly controlling manuscript quality and expanding journal functions and has published a series of papers reflecting innovative ideas and technologies, which not only improve the academic influence of the journal, but also promote the development of traumatology in China. In 2023, the journal will follow the demands of the 20th National Congress of the Communist Party of China, uphold fundamental principles and break new grounds, develop internationally on the basis of domestic situations to build a world-class journal in the field of traumatology.

During coronavirus disease 2019 epidemic, the treatment of severe trauma has been impacted. The Consensus on emergency surgery and infection prevention and control for severe trauma patients with 2019 novel corona virus pneumonia was published online on February 12, 2020, providing a strong guidance for the emergency treatment of severe trauma and the self-protection of medical staffs in the early stage of the epidemic. With the Joint Prevention and Control Mechanism of the State Council renaming "novel coronavirus pneumonia" to "novel coronavirus infection" and the infection being managed with measures against class B infectious diseases since January 8, 2023, the consensus published in 2020 is no longer applicable to the emergency treatment of severe trauma in the new stage of epidemic prevention and control. In this context, led by the Chinese Traumatology Association, Chinese Trauma Surgeon Association, Trauma Medicine Branch of Chinese International Exchange and Promotive Association for Medical and Health Care, and Editorial Board of Chinese Journal of Traumatology, the Chinese expert consensus on emergency surgery for severe trauma and infection prevention during coronavirus disease 2019 epidemic ( version 2023) is formulated to ensure the effectiveness and safety in the treatment of severe trauma in the new stage. Based on the policy of the Joint Prevention and Control Mechanism of the State Council and by using evidence-based medical evidence as well as Delphi expert consultation and voting, 16 recommendations are put forward from the four aspects of the related definitions, infection prevention, preoperative assessment and preparation, emergency operation and postoperative management, hoping to provide a reference for severe trauma care in the new stage of the epidemic prevention and control.

Pulmonary blast injury has become the main type of trauma in modern warfare, characterized by externally mild injuries but internally severe injuries, rapid disease progression, and a high rate of early death. The injury is complicated in clinical practice, often with multiple and compound injuries. Currently, there is a lack of effective protective materials, accurate injury detection instrument and portable monitoring and transportation equipment, standardized clinical treatment guidelines in various medical centers, and evidence-based guidelines at home and abroad, resulting in a high mortality in clinlcal practice. Therefore, the Trauma Branch of Chinese Medical Association and the Editorial Committee of Chinese Journal of Trauma organized military and civilian experts in related fields such as thoracic surgery and traumatic surgery to jointly develop the Clinical treatment guideline for pulmonary blast injury ( version 2023) by combining evidence for effectiveness and clinical first-line treatment experience. This guideline provided 16 recommended opinions surrounding definition, characteristics, pre-hospital diagnosis and treatment, and in-hospital treatment of pulmonary blast injury, hoping to provide a basis for the clinical treatment in hospitals at different levels.

With the strong support of the editorial members, Chinese Journal of Trauma has accomplished its annual tasks of organizing, reviewing and publishing manuscripts timely and efficiently and won the prizes from Science and Technology Association of Chongqing and Chinese Medical Association since the establishment of the 7th editorial board of the journal last year. The author mainly summarizes the organization and quality control measures of annual thematic manuscripts and new achievements and strengthens some ideas on how to make journal better next year and in the future.

Blast injury of the chest injury is the most common wound in modern war trauma and terrorist attacks, and is also the most fatal type of whole body explosion injury. Most patients with severe blast injury of the chest die in the early stage before hospitalization or during transportation, so first aid is critically important. At present, there exist widespread problems such as non-standard treatment and large difference in curative effect, while there lacks clinical treatment standards for blast injury of the chest. According to the principles of scientificity, practicality and advancement, the Trauma Society of Chinese Medical Association has formulated the guidance of classification, pre-hospital first aid, in-hospital treatment and major injury management strategies for blast injury of the chest, aiming to provide reference for clinical diagnosis and treatment.

Hemorrhagic shock and lethal massive hemorrhage are leading causes of death in both combat and civilian trauma casualties, accounting for more than 80% of deaths in operating rooms and 70% of deaths within 24 hours after trauma. Management of such patients is the main challenge and core competence in establishment of a trauma center. Damage-control resuscitation measures in pre-hospital settings include following ABCs rules, implementing appropriate transfusion and infusion strategies based on pre-hospital transport time, maintaining blood pressure based on a specific injury, and using tranexamic acid. The core of damage-controlled resuscitation in in-hospital settings is early correction of traumatic coagulopathy by massive transfusion. Damage-control surgery in pre-hospital settings consists mainly in cervical spine protection, pelvic band fixation, thoracic drainage, direct compression hemostasis, etc. Resuscitation aortic balloon occlusion for non-compression lethal hemorrhage is the most promising life-saving means. Damage-control surgery in in-hospital settings includes damage control laparotomy, thoracotomy, orthopedic surgery and craniotomy. Only a combination of damage-control surgery and damage-controlled resuscitation in prime time can ultimately save patients with such severe trauma.

Trauma score, trauma registry and construction of trauma database are the cornerstones for the quality improvement of trauma centers. Abbreviated injury scale (AIS)/injury severity score (ISS) has been used as the basis for evaluation of trauma centers in lots of countries since 2008, and has now developed into a globally recognized trauma scoring system. The authors introduce the changes in the number of codes and the setting of scores in the nine versions of AIS released since 1971, as well as the application effects of the AIS/ISS scoring system in recent years. Combined with the actual clinical cases, the errors in the current clinical application of AIS/ISS are analyzed. The construction of trauma registry and database in China has just started. The current focus is not to propose new trauma scores, but to correctly and accurately apply AIS/ISS scores first.

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.
