The child has broken skin and was bitten. Do you want tetanus? In what situations can you not fight?

Children are naughty and active, and there will always be various bumps, falls, or stab wounds. At this time, do you need a tetanus shot? Parents are always worried about not getting injections. If they are infected with tetanus, the consequences will be very serious; let’s get injections, some wounds don’t seem to be serious enough to need injections, and I heard that there is a risk of allergy to this injection? So let me talk to you today, under what circumstances do you need a tetanus shot?

1. What are the hazards of tetanus?

Tetanus is a specific infection caused by Bacillus tetanus. Tetanus bacillus is an anaerobic bacteria that exists in human or animal feces, soil, and rust, and cannot survive when exposed to air. Tetanus bacteria invade the human body through wounds and multiply rapidly in an oxygen-deficient environment. They produce toxins that primarily attack motor neurons in the nervous system. Therefore, when the disease occurs, patients often show symptoms such as trismus, paroxysmal spasm, and tonic spasm. The incubation period of tetanus is generally about a week, and of course there are occasional phenomena that occur within 24 hours or after several months or years. Common tetanus is often caused by improper wound treatment. When there are more outdoor activities in spring, summer and autumn, children's skin breakage, falls, and scratches by outdoor sports equipment often occur, which is a high incidence period of tetanus infection.

2. In which case is a tetanus shot necessary?

Although the fatality rate of tetanus is high, not every injury will result in tetanus infection. Because tetanus bacteria cannot survive in the air, it is not easy to grow tetanus bacteria on wounds that are exposed to air. Unless an "anaerobic microenvironment" is formed locally. For example, the following five situations: 1. Small wounds but deep puncture wounds. Such as deep stab wounds with nails, fish hooks or needles. 2. There is foreign body residue in the wound, and there is a lot of necrotic tissue in the wound; 3. The wound is contaminated with soil, feces, sputum, or contains rust, and the injured part is in places with a lot of body bacteria such as the armpit, groin or perineum; 4. .Burns, scalds, frostbites, fireworks, bullets or shrapnel, and metal scratches; 5. Open fractures or crush injuries.

3. How to judge whether to take a tetanus shot?

The following steps can help you quickly determine whether your child needs a tetanus shot: Step 1: Look through your child's vaccine book. When children are 3 months, 4 months, 5 months and 18 months old, they must be vaccinated against DTP for free. The DTP vaccine contains ingredients to prevent tetanus, which can protect for about 5-10 years, so that the child has enough tetanus antibodies in the body. The child still needs to be vaccinated with a tetanus vaccine when he is 6 years old. Therefore, children under 11 years old are injured and do not need to be vaccinated against tetanus. This also shows that it is very important to vaccinate children on time. Step 2: Determine the type of wound. According to the types of wounds mentioned above, see what kind of situation your child's wounds belong to, and decide whether you need to seek medical attention in time. When the child's wound is unclean or contaminated, and if the child is not fully immune, or the parent is unclear about the child's immune history, they must go to the hospital immediately and let the doctor decide whether to take a tetanus shot. Generally speaking, tetanus injection is a first aid measure to prevent tetanus, which is a passive immunization method. It's quick-acting and can get rid of germs in the first place, but its protection is short-lived and will expire in a few days or weeks, and it may cause severe allergies. Therefore, hospitals must do allergy tests before giving tetanus shots to the injured. Parents should also remember that after the child has received the tetanus shot, he must observe the doctor for 30 minutes to see if the child has any adverse reactions. In the event of an allergic reaction, it will seriously endanger the safety of the child's life, and parents must not be careless.
