In addition to saving patients’ lives and promoting functional recovery of injured parts, doctors should also follow aesthetic principles during repair surgery to minimize the impact of trauma on patients’ appearance when performing early treatment such as emergency resuscitation and trauma repair. According to the classification of emergency trauma patients according to the injured parts, the incidence is hand, head, both upper limbs, both lower limbs and trunk in descending order. For these patients, if only simple debridement and suturing are carried out according to the principles of conventional trauma treatment, and the cosmetic desire of patients is neglected, it may lead to some patients leaving big scar although the wound is healed, which extremely affects the aesthetics and even requires second-stage surgery to remove the scar for repair, increasing the pain of patients. In fact, if the whole process from initial wound treatment to wound removal and later recovery can be handled according to the following plastic surgery principles, it will enable patients to achieve the purpose of cosmetic surgery while repairing and treating trauma, and minimize the “physical and mental” damage caused by trauma. 1.Full understanding of the condition, first heavy, then light, first urgent, then slow. Since the choice of repair method is based on the accurate judgment of the injury, the repair process is based on the premise of the smoothness of the injury, so a full understanding of the condition and accurate assessment of the condition before surgery is very necessary. 2.The removal of traumatic tissues should be appropriate when clearing trauma Plastic surgery, like other disciplines, also emphasizes that the clearing must be thorough, and the tissues that have been completely necrotic should be completely removed. However, the clearance of cosmetic organs and functional organs should be slightly more conservative. 3.Both appearance and function Plastic surgery attaches great importance to the recovery of appearance. However, for the repair of functional parts, functional recovery should be given priority, so that both can be taken into consideration. 4.Strictly non-invasive operation An important basic principle of plastic surgery is non-invasive operation, i.e., gentle and meticulous operation, fine and sharp instruments, and no more new damage to tissues as far as possible during the operation. Early closure of the wound surface Early closure of the wound surface can reduce the chance of local and even systemic infection and the patient’s systemic consumption, and reduce the serious scar growth caused by the delayed healing due to exposure. 6. The choice of repair method should be simple to complex, taking into account aesthetics When choosing a method, not only should the safety and reliability of the method and the possibility of complications be considered, but also the cosmetic requirements of the injured area and the patient’s age, occupation, economic situation, etc., so as to minimize the cost and achieve maximum results. 7, the full application of the aesthetic basis and cultivation have mastered some basic principles and skills in aesthetic plastic work, with good aesthetic cultivation of the doctor is from the perspective of aesthetic plastic surgery to look at emergency trauma, such as: he sees not only the wound, but also see the relationship between the wound and the normal skin texture structure, and will be in the repair process of visionary improvement and coordination of this relationship. 8, early active functional exercise and rehabilitation to reduce the occurrence of posterior deformity Correct functional exercise, and with drugs, braces, traction and compression is important to reduce and reduce the occurrence of posterior deformity. 9, posterior deformity of plastic repair to choose the right time
