Methods for examining intestinal obstruction
The simplest test for intestinal obstruction is an upright abdominal X-ray, which can diagnose intestinal obstruction if dilated bowel loops and fluid levels are seen. Diagnosis can also be based on the patient's history and physical signs, such as nausea, vomiting, cessation of passing gas or stool, etc. Currently, abdominal CT can also diagnose intestinal obstruction, with the simplest method being the upright abdominal X-ray. Different types of intestinal obstruction require different treatments. For obstructions caused by tumors or volvulus, prompt surgical treatment is necessary. For general intestinal obstructions, such as those caused by adhesions or intestinal dysmotility, the preferred treatment includes fasting, hydration, anti-inflammatory medications, and other supportive measures. For elderly patients with obstipation-induced obstruction, enema treatment can be initiated first.
Which department should I go to at the hospital for a tetanus shot?
Tetanus shots should be administered at a regular hospital in the emergency department. There are two types of tetanus injections: one that requires a skin test, called tetanus toxoid, and one that doesn't require a skin test, called tetanus immunoglobulin. It is generally recommended to get the tetanus shot within 24 hours of injury, and it is best to avoid alcohol before the injection. Drinking can cause dilation and reddening of the skin's capillaries, which can affect the results of the tetanus skin test. Tetanus is usually caused by the invasion of Clostridium tetani into the body, a type of anaerobic bacterium. Thus, for wounds that are small, deep, and heavily contaminated, such as with dirt, rust, or in cases of open fractures, anti-tetanus treatment is essential, and a tetanus shot can be administered in the hospital's emergency department.
Is the tetanus shot safe?
It is safe to receive tetanus treatment at an accredited hospital. There are two types of tetanus injections: the tetanus toxoid, which requires a skin test, and the tetanus immunoglobulin, which does not require a skin test. Alcohol consumption must be avoided before using the tetanus toxoid. If the skin test is negative, the injection is safe. The other type, tetanus immunoglobulin, can be used directly without a skin test. Tetanus injections from reputable manufacturers and hospitals are safe. However, some people may experience symptoms such as pain, nausea, and vomiting during the tetanus injection. Typically, these symptoms can be alleviated and disappear with symptomatic treatment after the injection.
When does tetanus occur?
Tetanus is an infection caused by the invasion of the body by Clostridium tetani. Clostridium tetani is an anaerobic bacterium and an opportunistic pathogen, which is likely to cause tetanus in conditions such as anaerobic environments, deep wounds, or heavily contaminated wounds. Therefore, in cases where wounds are relatively small yet deep, and are considered to be in an anaerobic environment, or are contaminated with rust or soil, or in situations such as open fractures, blast injuries, gunshot wounds, and animal bites, tetanus injection treatment is necessary. It is generally recommended to administer the injection within 24 hours, and a skin test should be conducted before the injection, with alcohol consumption prohibited.
What is tetanus?
Tetanus infection occurs when Clostridium tetani invades the human body through skin and mucosal membranes, producing certain neurotoxins that lead to symptoms. As Clostridium tetani is an anaerobic bacterium, it typically thrives in anaerobic environments and is often found in heavily contaminated, muddy, or rusty conditions. Therefore, if there is an infection in a wound that is deep, located in an oxygen-poor environment, or heavily contaminated with dirt or rust, or in cases of extensive open fractures, explosion injuries, etc., anti-tetanus treatment is essential. It is generally recommended to administer an injection within 24 hours of the injury, which includes tetanus toxoid that requires a skin test—this is not to be used by patients with allergies—and tetanus immunoglobulin, which does not require a skin test.
When to get a tetanus shot?
Tetanus is caused by the invasion of the body by tetanus bacillus, a type of anaerobic bacterium that generally thrives in anoxic environments or heavily contaminated wounds such as those exposed to polluted soil or rust. Therefore, if the wound is deep, is in an anoxic environment, or is severely contaminated with soil, rust, or is an open fracture with expanded area, explosive injury, gunshot wound, or animal bite, tetanus treatment is required. Tetanus injections include tetanus toxoid, which requires a skin test, and tetanus immunoglobulin, which does not require a skin test, with an injection generally recommended within 24 hours.
Which part of the body is the tetanus shot administered?
Tetanus injections are given as intramuscular injections in the upper arm or the buttock. Tetanus vaccines include tetanus antitoxin, which requires a skin test. Patients with a positive skin test must either undergo desensitization therapy or avoid using it, and can switch to tetanus immunoglobulin, which doesn't require a skin test but is more expensive than tetanus antitoxin. The purpose of the tetanus shot is to prevent infection by Clostridium tetani, an anaerobic bacterium. It is particularly important for patients with deep wounds or heavily contaminated wounds; or wounds contaminated with rust or soil to receive tetanus treatment to prevent Clostridium tetani from colonizing the body through wound mucosa and producing neurotoxins that affect breathing.
Can I get a tetanus shot in the emergency room?
The injection of tetanus shots is performed in the emergency department of regular hospitals. Tetanus shots are divided into tetanus toxoid, which requires a skin test, and tetanus immunoglobulin, which does not require a skin test. If the skin test for tetanus toxoid is positive, indicating an allergy, it cannot be injected, and must be replaced with the slightly more expensive tetanus immunoglobulin. It is generally recommended to administer the injection within 24 hours after injury to prevent infection by Clostridium tetani. Clostridium tetani is an anaerobic bacterium. It is necessary to administer tetanus treatment for injuries that are deep, in anaerobic conditions, contaminated, heavily contaminated with soil, rust, open fractures, etc., since these conditions can be conducive to tetanus infection.
Can I eat tomatoes after a tetanus shot?
You can eat tomatoes after receiving a tetanus shot. There are two types of tetanus injections: tetanus toxoid, which requires a skin test, and tetanus immunoglobulin, which does not require a skin test. If you are to receive the tetanus toxoid, it is essential to perform a skin test beforehand. If an allergy is present, its use is prohibited. Furthermore, it is advised to abstain from alcohol before getting a tetanus shot to avoid any skin redness caused by drinking, which can affect the outcome of the skin test, leading to a failure in the indication for the tetanus injection. There are no contraindications regarding eating tomatoes after a tetanus shot. It is generally recommended to get the tetanus shot within 24 hours after injury.
How many times do you need to get a tetanus shot?
If tetanus vaccination is required due to an injury, one injection is sufficient. There are two types of tetanus shots. One is called tetanus antitoxin, which is extracted from horse serum. For this, a skin test is needed to check for allergies. If allergic, tetanus antitoxin cannot be used; if not, it can be used. The other type is refined tetanus antitoxin, also known as tetanus immune globulin, extracted from human serum. This type does not require a skin test and can be used directly, but it is more expensive than tetanus antitoxin. If tetanus treatment is needed for each injury, one injection is sufficient.
