The diagnosis of traffic accident trauma was confirmed by laboratory and imaging tests. The patient was treated with debridement, cosmetic suture, oral cefixime dispersible tablets, and topical recombinant human basic fibroblast growth factor, and recovered well after active treatment, and was very satisfied with the results. Basic information] Female, 16 years old [Type of disease] Trauma [Hospital] The First Affiliated Hospital of Kunming Medical University [Date of consultation] May 2021 [Treatment plan] Surgical debridement + medication (cefixime dispersible tablets, recombinant human basic fibroblast growth factor) [Treatment cycle] Hospitalization for 7 days, follow-up for 6 months [Treatment effect] Wound recovered well after treatment, and was discharged from the hospital without incident. First Consultation Chen is a high school student. One gloomy evening, Chen came to my clinic accompanied by her mother. Chen told me that she had been thinking about the model test on her way home from school in the afternoon, and then collided with a battery car at the corner. At the moment of the collision, her mind went blank, and she subconsciously protected her face with her hands. After falling heavily to the ground, she gradually felt pain in her elbow joints and knees, and continued to have vague pains in both ears. The mother was notified, worried, and rushed to the scene of the accident in a hurry, so she came to the clinic. I carefully did a physical examination for Chen, body temperature 36.7 ℃, heart rate 68 times / min, blood pressure 130 / 80 mmHg; mental clarity, no obvious trauma to the ears, the external auditory canal without congestion, the bilateral tympanic membrane is intact, the forehead and the hairline of the intersection of the wound of about 3.0 cm in length. He was admitted to the hospital with a preliminary diagnosis of traffic accident trauma. After being admitted to the hospital, Chen continued to improve laboratory tests and imaging examinations, and the results are shown below. Considering that Chen had multiple abrasions on both arms and lower legs, he underwent debridement. I told Chen that this process was a bit painful and that he had to endure it. After the wound treatment was completed, a tetanus injection was given to Chen. In order not to affect the aesthetic appearance of the area, Chen chose to use cosmetic stitches to close the wound, and was given cefixime dispersible tablets and topical recombinant human basic fibroblast growth factor to promote wound healing. 1 week later, the wound was rechecked to be well healed, and was discharged from the hospital. (X-ray of right calf: no obvious bone damage of right tibiofibula) (MRU scanning image of right shoulder: no definite abnormality of shoulder joint correspondence, no definite swelling of surrounding soft tissues) (After the wound at the intersection of forehead and hairline was closed by cosmetic stitches, the dressing was changed every 2 days for Chen, and the wound was kept dry and clean. 7 days later, Chen was examined, and the localized abrasion had been crusted, and there was no blood oozing or bleeding from the wound. There was no blood seepage or oozing from the wound. The wound at the intersection of the forehead and hairline was healing well, with no signs of infection. Chen was in good spirits and recovered well, so he was discharged from the hospital. When he was discharged from the hospital, I advised him to keep the scar clean, continue to use topical recombinant human basic fibroblast growth factor, and come to the hospital for regular checkups. Precautions I am glad that Chen’s wound healed well after treatment, but after discharge, we still need to pay attention to wound care and inform the doctor of any obvious abnormal reaction or discomfort. 1, after the treatment of trauma patients, should continue to observe the trauma site for swelling and pain, bruising, deformity, abnormal activity, poor healing, etc. If the above problems occur, timely follow-up is recommended; 2, after discharge from the hospital, the first month, the second month, the third month, the sixth month, and one year need to go to the hospital for review once, in order to help to understand the recovery of the wound localization; 3, the diet, to a light diet, it is recommended to Eat high-protein foods, such as fish, beef, milk, eggs, etc., as well as vitamin-rich fruits, such as apples, oranges, etc., which can effectively strengthen the body, to a certain extent, to speed up the recovery of trauma. Fifth, personal perception Trauma refers to mechanical factors acting on the local, resulting in the destruction of the integrity of the tissue structure or dysfunction, resulting in trauma caused by a multitude of factors, including violence, high temperature, cold, electric current, radiation, acid, alkali, gas poisonous insects, mosquito bites and so on. Trauma can occur in any population, age, due to the rapid development of industry, transportation, the incidence of trauma is increasing. Among them, traffic injuries account for the first place of trauma, and in recent years, fall injuries are also increasing. Therefore, if you are in a dangerous work environment you should wear protective clothing, wear a helmet, and strictly enforce safety norms to prevent accidents at work. Strictly enforce traffic management system and measures to restrict vehicles from traveling at high speeds to reduce or even eliminate the occurrence of serious accidents. Being warned by this case, avoid being distracted when walking on roads with heavy traffic, which may bring unexpected consequences if you are not careful.
