How to administer an injection if the tetanus skin test is negative
A negative tetanus skin test indicates that there is no allergy to tetanus antitoxin, and 1500 to 3000 units of tetanus antitoxin can be directly administered via intramuscular injection in the upper arm or buttock. If the wound is heavily contaminated or the injection is not timely, the dose may be doubled or tripled at discretion, and it is also necessary to clean and dress the wound. The purpose of administering tetanus antitoxin via intramuscular injection is to prevent infection by Clostridium tetani. Therefore, patients with heavily contaminated or deep wounds must receive tetanus antitoxin treatment.
Initial symptoms of tetanus
The bacterium that causes tetanus is Clostridium tetani, which is an anaerobic bacterium. If the wound is deep and enclosed in an environment lacking oxygen, it creates a suitable environment for the growth and reproduction of Clostridium tetani. Its incubation period is generally around one week. Early symptoms may include general fatigue, localized muscle tension, and uncontrollable spasms. The first muscles affected are usually the facial chewing muscles, and it can then progress to intense, spasmodic contractions of muscles throughout the body, and even cause fractures. Mild stimuli such as light, sound, or drinking water can trigger and worsen these symptoms, somewhat similar to rabies. However, a characteristic feature of tetanus is that the patient remains mentally clear. Most patients may die from respiratory spasms leading to asphyxiation, heart failure, or lung infections.
What are the symptoms of mild tetanus?
Symptoms of mild tetanus may include the following: Firstly, localized muscle spasms or brief spasms in a single muscle. Additionally, one may experience facial numbness, facial asymmetry, and difficulty swallowing. Generally, these symptoms are mild and do not affect normal life. Therefore, if tetanus occurs, one should first go to the hospital for further relevant examinations and treatment. The general treatment involves administering penicillin for infection control. Additionally, symptomatic treatment includes sedatives to reduce spasms. Attention should also be paid to diet; it is advisable to drink plenty of water and consume fresh vegetables and fruits. One should avoid spicy, stimulating foods, seafood, and yeast-containing foods like beef and mutton to minimize the occurrence of tetanus symptoms.
Can tetanus be cured?
Tetanus is a curable disease. It is usually caused by an infection with the tetanus bacillus, which produces a specific infection in the human body. Clinically, it is mainly manifested as muscle tension and rigidity, with the primary symptoms being difficulty opening the mouth, a sardonic smile, neck stiffness, and opisthotonos. In severe cases, it can lead to respiratory confusion, respiratory arrest, or cardiac arrest. Therefore, patients with tetanus should go to the hospital for treatment as soon as possible. With standardized and systematic treatment, the vast majority of patients can be cured.
Does tetanus cause fever in its early stages?
Tetanus is actually a disease caused by the tetanus bacillus, generally entering the body after mucous membrane damage. In the early stages of tetanus, there usually are no fever symptoms. Fever typically appears in the middle to late stages. Generally, it is preceded by symptoms like episodic muscle spasms or tonic spasms. During this period, the incubation period can be about one week. In this time, the patient may experience symptoms such as general fatigue, headaches, and dizziness. Under circumstances where infection is likely, it is crucial to administer tetanus antitoxin promptly to effectively prevent the disease. Since the disease's morbidity and danger increase significantly in its middle to late stages, and the likelihood of death is also relatively high.
How to treat tetanus?
Generally speaking, a tetanus shot needs to be administered intramuscularly, but a skin test must be conducted before injection because tetanus vaccines can easily cause allergic reactions. The skin test usually involves a subcutaneous injection on the palm side of the forearm, followed by an observation period of 15 to 20 minutes. If there is no redness or itching, and the skin test is negative, then the vaccine can be administered intramuscularly, usually in the buttock. However, if the skin test is positive, as indicated by symptoms like redness, significant itching, or even systemic symptoms such as dizziness and cold sweats, it shows that the skin test for tetanus is positive. In this case, one can opt for a desensitization injection of diluted tetanus vaccine, followed by intramuscular injections four times, once every half hour, needing about two hours to complete.
What should I do if I drink alcohol with tetanus?
If there are high risk factors for tetanus infection after an injury, and alcohol has been consumed, it is generally advisable to wait until sobriety before conducting relevant skin tests. Currently, there is no clear research on the relationship between alcohol consumption and an allergy to tetanus antitoxin. It is not very clear whether alcohol impacts the results of a skin test, so it is safer to perform the test after sobering up. Since the consequences of a tetanus infection can be severe, and the tetanus injection itself carries a certain risk of anaphylactic shock, which can lead to multiple organ problems and even be life-threatening, it is generally safer to conduct the skin test after sobering up and then proceed with the timely injection treatment. If the skin test is positive, tetanus immunoglobulin should be chosen promptly.
How long does a tetanus shot last?
The duration of effectiveness for a tetanus shot depends on the specific type of injection used, as different injections vary in their duration of protection. Generally, the protection lasts about two to three days. In cases of infection, it is usually necessary to administer the vaccine within 24 hours. Under these circumstances, a period of about two to three days can be used to clean the wound, thereby achieving the best preventive effect. Additionally, there are other vaccines that are ten to twenty times more effective than this type of vaccine, with a typical prevention time ranging up to 15 days or even about a month. Of course, after receiving the tetanus vaccine, it is important to monitor for any allergic reactions, as different injections may vary in their degree of allergenicity, and individual reactions can differ based on personal health conditions.
Can you drink alcohol with tetanus?
After receiving a tetanus vaccine, it is not recommended to drink alcohol. It is best to avoid spicy, stimulating, and greasy foods. Usually, when patients are injured, they may need to receive a tetanus vaccine. Especially when injured by rusty metal, the tetanus vaccine can effectively prevent tetanus. However, drinking alcohol at the same time as receiving the tetanus vaccine can easily lead to a drug reaction, causing adverse reactions. For example, increased heart rate, dizziness, palpitations, vomiting, and even shock, which can be life-threatening in severe cases. Furthermore, drinking alcohol is also detrimental to the healing of wounds. Depending on the recovery of the body, patients can generally drink a small amount of alcohol after a week.
Do not get a tetanus shot before a certain age.
Tetanus antitoxin, this type of vaccine, generally has no significant age restrictions. It is usually best not to administer it before the age of one, as it involves using a toxin to combat toxins and prevent certain diseases. Therefore, it is advised not to vaccinate before one year of age. However, not everyone needs to be vaccinated against tetanus; it only serves as a preventive measure and is only necessary if there is a possibility of infection. For instance, vaccination is required when there are deep wounds or apparent injuries from rusty metal, as these conditions have a higher risk of infection. In such cases, administering tetanus antitoxin can effectively prevent infection. Thus, vaccination should depend on the specific situation rather than on age.
