Pay special attention to the prevention of tetanus after explosion injuries. Every year after the Spring Festival, the hospital will treat people who injured their hands due to setting off fireworks and firecrackers and caused tetanus due to improper treatment. Due to untimely treatment, the mortality rate is very high. Gao, here I would like to introduce some relevant knowledge so that friends can have a preliminary understanding of this. "Tetanus" is an acute infectious disease characterized by Clostridium tetani invading human wounds, growing and multiplying in an anaerobic environment, producing neurotropic exotoxins, and causing tonic spasms of muscles throughout the body. Severe cases can cause laryngospasm and lead to death. Wang Yarong, Department of Burns and Plastic Surgery, Datong Third People's Hospital. Explosion injuries caused by setting off firecrackers are generally small and deep inside. They happen to be a hypoxic environment, which can easily cause the propagation of Tetanus bacilli, thus causing tetanus. Symptoms of tetanus: Generally, there is wound infection, soreness and pain in the muscles of the lower back, difficulty in opening the mouth, and a forced smile on the face, and the symptoms gradually worsen. In severe cases, laryngospasm may suddenly occur, causing difficulty in breathing, and death may occur if rescue is not timely. Diagnosis of tetanus: deep wound, heavy contamination, infection, fever, back pain, soreness or difficulty opening the mouth, neck stiffness, and opisthotonus. The incubation period is 7-14 days. The shorter the incubation period, the more serious the condition. Prevention of tetanus: It is important to clean the wound thoroughly in the early stage. For wounds with a small mouth and a large belly, the wound should be enlarged and drained adequately. Tetanus vaccine is very effective, so as long as the skin is damaged, tetanus vaccine should be taken. Treatment of tetanus: Full wound expansion, systemic anti-infection, large-dose intravenous infusion of tetanus antitoxin injection to keep the airway open, nutritional support treatment, sedation, avoidance of light, and avoidance of sound. Typical case: Patient, a 62-year-old male, injured his right hand for 7 days due to setting off firecrackers. The wound was not treated, and he suffered from pain in the back muscles and difficulty opening his mouth for one day. He suffered from tetanus? He was admitted to the hospital. After hospitalization, the wound was cleaned, the wound was enlarged, and the wound was partially sealed with tetanus antitoxin. 20,000 units of tetanus antitoxin were intravenously dripped daily, and 8 million units of penicillin were intravenously dripped every 8 hours. At the same time, he was protected from light and sound. After being hospitalized for 6 hours, he developed dyspnea and laryngospasm. A tracheotomy was performed immediately, diluted midazolam was continuously infused intravenously, and intravenous nutrition was given. During the treatment, a lung infection occurred, and sensitive antibiotics were given. Two weeks later, The symptoms improved significantly and he was discharged from the hospital after 4 weeks. Tetanus treatment is difficult, but prevention is very convenient and effective. Therefore, it is necessary to have this concept. As long as the skin is damaged, tetanus vaccination must be prevented.
