[Clinical effects of anterograde sural neurovascular flap in repairing skin and soft tissue defect around the knee].

Objective: To explore the clinical effects of anterograde sural neurovascular flap in repairing skin and soft tissue defect around the knee. Methods: Nine patients with skin and soft tissue defect around the knee admitted to Beijing Fengtai YouAnMen Hospital from May 2011 to December 2018, were included in this retrospective descriptive study, including 8 males and 1 female, aged 16 to 65 years. The wound area after debridement ranged from 8 cm×5 cm to 18 cm×10 cm. Anterograde sural neurovascular flap was used to repair the wounds in 9 patients, with the area ranging from 9 cm×6 cm to 20 cm×12 cm. The donor sits of flaps in 2 patients were closed and sutured directly, and the donor sits of flaps in 7 patients were repaired with medial split-thickness skin graft of the ipsilateral thigh. The flap survival, complications, and follow-up after operation were recorded. Results: The flaps survived and the blood supply was good in 8 patients and the wounds were closed. One patient developed skin ischemic necrosis which was cured after three weeks of dressing change. All the skin grafts in the donor site of flap in 7 patients survived. In 6 months to 5 years of follow-up after surgery, the skin flap had good texture, color, and shape, and normal sensation. Except for one patient whose knee had poor recovery of function, the knee joint function of the other patients recovered well. Conclusions: The anterograde sural neurovascular flap has the advantages of high survival rate, satisfactory appearance and functional recovery post surgery, and is an ideal flap for repairing the skin and soft tissue defect around the knee.

[Comprehensive treatment on ten patients with perianal necrotizing fasciitis].

Ten patients with perianal necrotizing fasciitis were admitted to our department from June to December 2016. There were 8 men and 2 women among the patients, aged 42 to 69 years. Early and complete debridement surgery and comprehensive supportive treatment during perioperative period were carried out to quickly stabilize the patient's overall condition, and wounds were sutured directly or repaired with autologous scalps and or adjacent local random flaps. After debridement, wound areas ranged from 10 cm×8 cm to 54 cm×21 cm, and area of the flap was about 8 cm×5 cm. The donor site of flap was sutured directly. After the operation, all skin grafts and the flap survived, and wounds of all patients healed. During follow-up of six months to one year, there was no recurrence of perianal necrotizing fasciitis, and functions of the involved lower extremities didn't be influenced.

[One case of elderly patient with extremely severe burn complicated by ventricular tachycardia].

One elderly patient with extremely severe burn was admitted to our department on 4th August, 2017. The patient suffered multiple sustained ventricular tachycardia from post injury day 2 to 4 due to relatively high input volume during shock stage. Amiodarone could not be given through intravenous injection because of his low blood pressure. After consultation with cardiologist, ventricular tachycardia was corrected by electrical cardioversion of several times. According to this case, the first treatment is electrical cardioversion when elderly patient with extremely severe burn shows sustained ventricular tachycardia which can not be corrected with medicine.

[Initiation, development, and achievements of burn rehabilitation therapy in China].

Burn rehabilitation in China started from compression therapy in the mid-1970s, which showed the dual effects of prevention and treatment of hypertrophic scars. It not only promoted functional rehabilitation but also strengthened the confidence of patients in rehabilitation treatment. Thereafter, more therapies were brought into practice, such as intra-scar injection of triamcinolone acetonide, application of plastic splints, hydrotherapy, exercises with equipment, skin care, local therapeutic massage, active and passive exercises, as well as external use of drugs for inhibiting scars and pigments. Since the beginning of the 21st century, rehabilitation therapies have been gradually increasing. Psychological rehabilitation, occupational therapy, external use of silicone gel, wax therapy and sound, light, electricity, and radiation therapy have been carried out. Many hospitals have established foundations and held summer camps for children. As far as the whole country is concerned, compared with the huge demand, we still face a number of problems such as shortage of working staff, limited working space, capital chain rupture, lack of multi-disciplinary cooperation, untimely treatment, and incomplete rehabilitation. Nowadays, with increasing knowledge of burn rehabilitation and number of practitioners, improvement of equipment and economic situation, the pace of rehabilitation has accelerated, and the overall implementation of burn rehabilitation therapy has shown great vitality. Patients with burn injury involving over 80% total burn surface area (TBSA) of total burn area or full-thickness burn over 60% TBSA were cured and recovered in different levels of hospitals nationwide, which not only reflects the superb level of burn treatment in China but also reflects the overall improvement of rehabilitation level of the country.
