A car accident made Ms. Lu’s abdomen, left thigh to the knee of a large area of skin “disappeared”, the bacteria on the traumatic surface is attacking her body, if not timely treatment, life will be lost in an instant. In this life-and-death battle, the superb medical skills of multidisciplinary experts from Changzheng Hospital not only enabled Ms. Lu to be “reborn”, but also “recovered” the “lost” skin for her. Recently, Ms. Lu was discharged from the hospital. Ms. Lu, 48 years old from Kunshan, was knocked down and crushed by a speeding truck on her way to work 2 months ago, resulting in pelvic fracture, perineum, bilateral groin to the left thigh, large areas of skin and soft tissue tearing off, dripping with blood. After treatment at the local hospital, Ms. Lu, whose life was temporarily saved, was not free from the threat of death. Due to the huge area of missing skin and the serious loss of water and electrolytes, the patient’s wound was enlarged with every debridement, and the bacterial infection was out of control, putting her life in danger! The family, who had just come out of pain and sorrow, was once again plunged into despair. Three years ago, Ms. Lu’s husband unfortunately also died in a car accident. In order to save Ms. Lu’s life, her family came to the Emergency Department of Changzheng Hospital from Kunshan with a glimmer of hope. At this time, the patient was already in a coma, and the bloodied left thigh and perineum were like an anatomical atlas of muscles, with more than 19% of the skin exposed. The emergency department quickly gave blood transfusion, rehydration and anti-infection treatment. After the condition was stabilized, the orthopedic department performed the first surgery of debridement plus pelvic immobilization, which laid a good foundation for future surgeries. However, such a large area of skin loss, the trauma has not been covered, water and nutrients continue to be lost, which means death for the patient, the only way to save the patient’s life is to carry out skin grafting surgery in time to cover the trauma. The only way to save the patient’s life is to perform a skin graft in time to cover the wound. With such a large area of missing skin, a large number of skin grafts from other parts of the body will be taken, and the new wound will be at risk of infection and poor healing. Moreover, with a much wider range of scars all over the body, how to select and design the skin flap became the key to the surgery. Associate Professor Zhu Xiaohai, Deputy Director of Plastic and Reconstructive Surgery, and Dr. Zhang Wenjun, Attending Physician, decided to use the latest technology to perform skin grafting on the patient, so that the patient’s wound could be closed in the shortest possible time. During the surgery, the surgeon first applied wound closure negative pressure drainage (VSD) to reduce the bacteria on the wound and promote the growth of fresh granulation tissue on the wound. One week later, the doctor removed the necrotic tissue of the wound, cleaned up the wound, using the MEEK method of skin grafting technology, take the patient’s scalp less than 3% of the body surface area of the skin source, through the special double wrinkled gauze can be extended by multiples of transplantation flap multiples of the extension of the flap, covering the patient’s 19% of the trauma, after 5 hours of “fine carving After 5 hours of “fine-tuning”, Ms. Lu’s huge wound was as if she had put on a “new coat” that was just right and interlocked. After the operation, the transplanted skin flap survived well, and Ms. Lu’s “lost” skin was finally “found” again. It is reported that the technology is the use of human scalp skin in accordance with a certain proportion of the expansion of skin grafting, so as to save the source of skin to cover the largest possible skin trauma. Take the scalp after the scalp in about a week can regenerate, can be repeated many times to take the skin. The use of this technique for the treatment of patients with large skin avulsions is rarely reported in the literature.
