What is tetanus? How tetanus is caused

Tetanus is a kind of clostridial infection, which can be caused by tetanus bacilli invading human wounds, growing and multiplying, and producing toxins. Tetanus bacilli and its toxins cannot invade normal ** and mucous membranes, so tetanus occurs after injury. Tetanus is a risk of any open injury.

The main one is a Gram-positive anaerobic bacillus that can easily enter through the wound, you should go for a vaccination, don't get infected.

No, tetanus is caused by infection with Clostridium tetani, a very powerful bacterium. Clostridium tetani is an anaerobic bacterium, the oxygen content in the air is sufficient, there is no suitable environment for it, oxygen has a strong killing effect on it, so it is impossible to get tetanus when blown by the wind. In addition, only a little skin is broken, the wound is not deep, and the wound surface can be fully in contact with the air, that is, it can fully contact oxygen, and it is not suitable for the growth of Clostridium tetani.

Clostridium tetani generally exists in the soil with insufficient oxygen in the external environment, if your wound is very deep and infected with Clostridium tetani, it is also bandaged, so that the wound is deprived of oxygen, providing a suitable growth environment for Clostridium tetani, and a large number of replications invade the blood, resulting in Clostridium tetani bacteremia, which will cause disease. In addition, the existing medical conditions after the onset of tetanus are not effective, and it is a complete terminal disease, and the person's life will end within seven days of the onset of the disease.

What is tetanus? What caused it? After reading it, I can't help but feel a chill down my back!

The cause of tetanus is that when a person has a traumatic injury, Clostridium tetani invades the human body and produces toxins, causing a specific infection. Tetanus bacillus, its spores are widely distributed in nature, especially in these soils, or in human and livestock droppings. Under normal circumstances, its spores do not cause disease, once the tetanus bacillus invades the wound ** or mucous membrane, especially with some oxygen storage bacteria or anaerobic bacteria at the same time, or the local tissue necrosis, there are soil or foreign bodies, polluting the wound, forming a local ischemia, hypoxic environment, at this time, tetanus bacillus, will grow and multiply on the wound, and will produce toxins.

One is a spasmodic toxin, which has a special affinity for the nervous system, which acts on a motor nerve cell in the anterior horn of the spinal cord, and finally causes continuous contraction of skeletal muscles throughout the body through the motor endplate, or a paroxysmal spasm. Another toxin is a hemolytic toxin, which can cause a necrosis of local tissues or a direct damage to the heart muscle. Once the tetanus bacillus grows in the anaerobic environment in the body, it produces spasmodic toxins and hemolytic toxins, and under the action of the two toxins, people will have symptoms such as muscle spasm and local tissue necrosis, and at this time, tetanus has appeared.

However, a local aerobic environment can inhibit the growth, reproduction and toxin production of tetanus bacilli in the body. After tetanus bacillus infection, it must have an anaerobic environment to survive, once this encounters a bad environment, it becomes a spor, at this time it stops moving, especially when it is aerobic, it loses its virulence and does not cause disease. In this way, once our body has external damage, especially narrow and deep wounds, which are easy to cause local environmental hypoxia, when dressing the wound, we must first disinfect the wound and make sure that the selected dressing material is clean, so as to prevent tetanus bacilli from growing, multiplying and producing toxins in the wound.

The above explanation of tetanus hair element will help us to improve our awareness of tetanus prevention.

It is a series of symptoms caused by infection with tetanus bacillus after trauma and burns, and the disease is dangerous and the mortality rate is high. **It is also particularly troublesome, but the prevention is simple, as long as you inject tetanus antitoxin. This medicine is not expensive, only more than three yuan a piece.

It is caused by tetanus bacillus in anaerobic bacteria, because the wound is deep into the muscle layer after scratching or bruising, that is, the layer of muscle, ** after debridement, there is no timely injection of tetanus toxoid (vaccine), this bacterium generally survives vigorously in a humid environment, so the probability of tetanus infection is more in rainy days scratches or trauma, if the wound reaches the muscle tissue, tetanus toxoid must be injected, which will prevent the occurrence of tetanus well, tetanus will be infected within a month of onset, and the whole body gangrene death.

The wound is infected with tetanus bacillus, so if you are pricked by something, especially a deep wound, you must have tetanus human immunoglobulin. In fact, as long as you go to the hospital for treatment after the injury, the doctor will prescribe this for you, which is a necessary diagnosis and treatment item.

** Broken, caused by infection.

The general wound is injured by some unclean things (human or animal bites), the wound is generally deep and narrow (general wounds are not excluded), the puncture wound of an item with tetanus bacilli**, multiplies in an oxygen-free environment, and it is difficult to control the infection once it is infected...

The incidence of tetanus is still very high in the current society, which is directly related to the increase in social complexity, and the disease of tetanus patients also needs us to understand the degree of cooperation of the patient's disease, because if the tetanus patient can not cooperate in time, then there will be certain complications of the disease.

Clostridium tetani is non-invasive, does not invade the blood circulation, and only grows and multiplies in local wounds. Its pathogenic effects are mainly caused by the production of exotoxins. Exotoxins mainly invade motor neurons in the spinal cord and brainstem, and once combined with nerve cells, they cannot be neutralized by tetanus antitoxin.

Clostridium tetani spores generally do not multiply after they invade local wounds.

If there is purulent infection combined with aerobic bacteria, local poor blood circulation caused by severe tissue trauma, or necrotic tissue and foreign body retention, forming a local anaerobic microenvironment, it is very conducive to the reproduction of Clostridium tetani. Bacteria proliferate in large numbers in the form of propagules and produce a large number of spasmodic toxins.

The toxin first binds to gangliosides in nerve endings, and travels backwards along the nerve sheath through spinal nerve roots to human anterior horn neurons of the spinal cord, and ascends to brain stem cells. Toxins can also be absorbed through lymphatic fluid and reach the central nervous system through the bloodstream.

In fact, the disease of tetanus patients ** first of all, we still need to deal with the wound in time, and then the disease of tetanus also needs the symptoms of the patient, because the disease of tetanus is not well handled, then with the increase of the severity of the disease, the symptoms or severity of the disease of the tetanus patient will also increase.

Tetanus is a specific infection caused by the tetanus bacillus, which can occur after various traumas, and can also occur in mothers and newborns who give birth under unclean conditions.

Tetanus bacilli are obligate anaerobes that are present in human and animal feces and can survive long periods of time in soil, where tetanus bacteria contaminate wounds after tissue injury.

Because of open fractures, trauma to a large number of muscles, and small and deep puncture wounds, the anaerobic environment caused by the proliferation of tetanus bacilli is prone to the production of tetanus spasmodic toxin and tetanus hemolytic toxin.

Tetanus spasmodic toxin binds to cells in the brain and spinal cord to produce a specific clinical condition of tetanus, causing individual muscles to spasm.

Tetanus can be prevented by early subcutaneous injection of tetanus antitoxin 1500 to 3000 units after trauma. If the trauma is severe, another injection can be given a week later.

Tetanus is a very serious disease, it has an incubation period, generally tetanus occurs after various traumas, and some patients are still newborns who are born in an unclean environment. Tetanus has an incubation period and can vary in length from 24 hours to years. The early stage of tetanus is manifested as general weakness, body aches, dizziness, etc., and the condition will gradually deteriorate, resulting in difficulty breathing and death, so it is necessary to be timely after suffering from tetanus.

1. At present, the most important method for tetanus is to prevent it, and after the body has been traumatized, it is necessary to go to the hospital in time for tetanus injection, and know the virus to control the disease. Therefore, it is more important to educate us about tetanus, to understand our own bodies, and to know how to deal with them.

2. After being diagnosed with tetanus, it is necessary to pay attention in time, and need to be isolated, if the patient has complications such as suffocation or spasm, etc., the doctor will carry out emergency treatment according to the patient's situation, and must have a special person to take care of it, so as to avoid accidents, and also need to use aseptic technology to prevent cross infection, and for patients with serious conditions, antibiotics or trachea incision are required according to the situation.

3. Therefore, we must always pay attention in our daily life, avoid injuries, learn and understand the emergency measures to be carried out after various physical conditions, and regularly go to the hospital for physical examination every year to enhance our resistance and avoid going to some crowded entertainment places. Live and eat regularly.

Tetanus (tetanus) is a specific infection of Clostridium tetani that invades the human body through ** or mucosal wounds, grows and multiplies in an oxygen-deficient environment, produces toxins and causes muscle spasms. Tetanus toxin mainly invades motor neurons in the nervous system, so the disease is clinically characterized by trismus, paroxysmal spasm, and tonic spasm, and the main muscle groups affected include masseter muscles, dorsal spinous muscles, abdominal muscles, limb muscles, etc. The incubation period for tetanus is usually 7 to 8 days and can be as short as 24 hours or as long as months or years.

The shorter the incubation period, the worse the prognosis. About 90% of patients develop the disease within 2 weeks of injury, and occasionally patients develop tetanus symptoms after removal of a foreign body that has remained in the body for many years. The population is generally susceptible, and trauma of all types and sizes can be contaminated with soil or sludge containing Clostridium tetani, but only a small number of patients develop the disease.

Injuries are more common in people during the warmer season, when there is a lot of outdoor activity. There is no long-lasting immunity after the disease, so it can be reinfected.

Tetanus is an acute infectious disease caused by the bacterium Clostridium tetani. The toxins produced by Clostridium tetani mainly affect the nervous system and can cause severe muscle spasms. Muscle spasms in the jaw can make it difficult to open the mouth, which is why tetanus is also known as "lockjaw."

Tetanus can also cause seizures, making it difficult for people to swallow or breathe.

Tetanus can occur at any age and has a high case fatality rate, but it can be prevented with vaccination. Tetanus is rare in developed countries, but it remains an important public health problem in developing countries, especially low-income countries. Tetanus remains a deadly threat to people who are not fully vaccinated against tetanus.

Tetanus vaccine has been included in the childhood immunization programme.

Acute infectious disease caused by Clostridium tetani, the germs mainly enter the human body through unclean wounds, which are mainly manifested as severe muscle spasms, which can cause fatal complications, and can lead to death if not timely, when the wound is deep, there is a foreign body or is contaminated, you should seek medical attention in time, and the doctor will thoroughly clean all wounds to prevent and remove Clostridium tetani infection, the purpose is to control muscle spasms and pain, and most patients can do it within a few weeks or months.

A quick overview of what tetanus is?

Tetanus is a toxic disease of the nervous system caused by tetanus bacillus exotoxin, which is characterized by progressive development of muscle rigidity, accompanied by episodic exacerbations, and if not timely**, the mortality rate is about 10 to 40%.

Western Medicine Name: Tetanus English Name:

tetanus

Department: Internal Medicine-

Main symptoms: facial spasm, angular arch reflexion.

Primary**: Bacterial infection.

Infectious: Non-infectious.

The early symptoms of tetanus are muscle cramps, often referred to as "cramps". The earliest symptom in most patients is facial muscle spasms, which are characterized by the inability to open the mouth and painful muscle spasms in front of the ears when chewing food. Many patients mistakenly think that it is a dental disease and go to the dentistry.

The dentist often only finds spasms of the masticatory muscles and temporal muscles, but there is no dental disease in the mouth that causes difficulty in opening the mouth. The more the patient is asked to open his mouth, the more the patient cannot open it, and even closes it tighter and tighter. At this time, if there is a slight negligence, it can be delayed, but if you have the knowledge of this diagnosis, think of tetanus and get it in time**, most of them can be cured.

However, many dentists do not necessarily have this knowledge, so there are many delays. Once the muscles of the whole body spasm and twitch, and then turn the head to think of tetanus, the prognosis is very bad.

Tongue depressor test for early diagnosis of tetanus. The examination method is to gently put a tongue depressor or other smooth wooden board that has been disinfected and cleaned, or even chopsticks, soup spoons, etc., on a suspected patient with tetanus who has recently had a cut and puncture wound**, and press down hard.

If the patient has immediate trismus and bites the tongue depressor and is not easily extracted, it is positive and can be judged to be an early manifestation of tetanus. Within 4-30 hours, all of these people will have typical tetanus symptoms.
