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.

The aim of this consensus is to propose standardise the treatment protocols for limb replantation for children therefore to serve as a reference for clinical practitioners in medical practices, and further improve the treatment and care for the traumatic limb amputations in children.

The polyfoliate perforator flap is a new type of flap that was developed on the basis of the traditional polyfoliate myocutaneous flap, polyfoliate fascial flap and perforator flap. It overturns the traditional idea that the deep fascial vascular network is the fundamental for a survival of the flap, and enables the flaps to achieve the best profile and function of the recipient areas with minimal damage to the donor area. In order to improve the understanding of the polyfoliate perforator flap and further standardise its clinical application, this paper forms a consensus on the definition, classification, indications, operative points and precautions of the polyfoliate perforator flap, so as to provide references in diagnosis and treatment process and practical application for the surgeons.

Objective:To investigate the clinical effect of percutaneous curved kyphoplasty in the treatment of old osteoporotic vertebral body with endplate fracture.Methods:Clinical data of 58 patients suffering from old osteoporotic vertebral bodies with endplate fractures from January 2018 to January 2020 were analyzed retrospectively. All patients had a single vertebral body fracture and were treated with bilateral injection of bone cement with percutaneous kyphoplasty (PKP). According to the shape of the puncture device, the patients were divided into a curved needle group and a ordinary group. There were 28 cases in the curved needle group, including 7 males and 21 females, aged 60-84 years old, with an average age of 71.8±7.8 years. The distribution of vertebral bodies with fractures: T 11 3 cases, T 12 5 cases, L 1 6 cases, L 2 5 cases, L 3 3 cases, L 4 4 cases, and L 5 2 cases. In the ordinary group, there were 30 cases, 8 males and 22 females, with an average age of 73.2±8.4 years (range, 61-88 years). The vertebral body distribution of fracture: T 11 3 cases, T 12 5 cases, L 1 7 cases, L 2 4 cases, L 3 4 cases, L 4 5 cases, and L 5 2 cases. The surgery time, amount of bone cement injection, and bone cement leakage rate were compared between the two groups, as well as the visual analogue scale (VAS) and Oswestry disability index (ODI) at 1 week, 6 months, and 1 year after surgery. Preoperative and postoperative vertebral midpoint height and kyphosis Cobb angle were measured. Results:All patients were followed up for 12-24 months, with an average of 14.7±2.9 months. The bone cement leakage rate in curved needle group (18%, 5/28) was lower than that in ordinary group (23%, 7/30), but there was no significant statistical difference (χ 2=0.27, P=0.607). The amount of bone cement injection and surgery time in curved needle group (5.0±0.5 ml, 55.2±6.9 min) were significantly higher than those in ordinary group (3.4±0.6 ml, 42.9±3.6 min, P<0.05) . The scores of VAS (2.3±1.0, 2.6±1.5) and ODI (27.5%±9.7%, 28.7%±11.3%) in curved needle group were lower than those in ordinary group (2.7±1.0, 4.5±1.1 and 31.8%±10.5%, 43.1%±13.4%) at 6 months after surgery and at the last follow-up after surgery. In the curved needle group, the Cobb angle was 25.5°±3.5° preoperatively, 18.4°±1.6° postoperatively, and 20.5°±4.9°at the last follow-up. The height of the vertebral body was 14.2±1.9 mm before surgery, 21.5±2.2 mm after surgery, and 20.1±3.6 mm at the last follow-up. Compared with the preoperative results, the kyphosis Cobb angle decreased and the height of the fractured vertebral body increased at the last follow-up, and the differences were statistically significant ( P<0.05). In the ordinary group, the Cobb angle was 24.4°±3.6° preoperatively, 23.1°±4.0° postoperatively, and 27.8°±2.9° at the last follow-up. The height of the vertebral body was 14.5±1.8 mm before surgery, 15.4±2.0 mm after surgery, and 12.7±1.0 mm at the last follow-up. At the last follow-up, the kyphosis Cobb angle increased and the height of the fractured vertebral body decreased compared with preoperative and postoperative 1 week, and the differences were statistically significant ( P<0.05). At 1 week after surgery, 6 months after surgery and the last follow-up, the Cobb angle of curved needle group was lower than that of ordinary group ( P<0.05), the height of vertebral body was higher than that of ordinary group ( P<0.05). Conclusion:Flexible application of percutaneous curved kyphoplasty in the treatment of old osteoporotic vertebral body with endplate fractures can effectively increase the riveting force of bone cement in the vertebral body, restore the height of endplate, and reduce the occurrence of kyphosis and chronic low back pain.

Objective:To explore the clinical technique and method of reconstruction large soft tissue defect of plantar by skin soft tissue dilatation combined with thigh cross leg flap to improve the weight-bearing function of plantar standing.Methods:From February 2015 to June 2019, 8 cases with plantar soft tissue defects were repaired with cross leg flap expanded from the healthy side of the thigh. Right foot in 4 cases, left foot in 3 cases and bilateral in 1 case. There were 5 males and 3 females. Ages ranged from 16 to 56, with an average age of 31. Clinical features: scar ulcer in 4 cases, bone-sticking scar in 4 cases, bone exposure in 1 case. After debridement, the area of skin and soft tissue defect was 9 cm×16 cm-12 cm×29 cm, the area of harvest expanded flap was 11 cm×18 cm-14 cm×30 cm. All flaps were fixed by cross-leg with pedicle. The pedicle division were performed one month after the skin flap transmission.Results:Of the 9 flaps transferred, 8 survived, 1 died in the distal part of the flap and was repaired by secondary expanded flap, and the donor site healed in linear scar stage. After 6-24 months follow-up, the plantar flap was in good shape and could walk with weight-bearing, without ulceration, and the protective tactile sensation was gradually restored in 12 months.Conclusions:The large-area soft tissue defect of plantar was repaired with the expanded cross leg flap in the healthy thigh, which also provide sufficient thickness of soft tissue to increase the ability of bearing weight and wearing resistance of the sole. It is a good alternative method to repair large area soft tissue defect of plantar under the condition of limited transfer of perforator flap and free flap.
