According to college surgical textbooks and routine hospital treatments, these treatments meet the requirements and must be taken orally to prevent infection. In fact, TAT can also prevent infection. But I was cut by a stone, and my hands and feet were infected for two weeks, and I healed myself without treatment. According to the surgical experience, new or clean nails will scratch the skin, and old or contaminated nails will do little harm to the skin, so there is no need to inject TAT serum or prevent infection. If the polluted nails hurt deep tissues and there is not enough oxygen (called anaerobic environment), it is easy to cause tetanus (tetanus is an anaerobic bacteria, which can only survive and reproduce infection in anaerobic environment), so TAT serum must be injected. Anti-inflammatory drugs should generally not be abused.
