Is tetanus easy to infect?
Tetanus is not easily contracted.Tetanus bacilli belong to anaerobes, and are prone to occur in conditions where the wounds are deep, in an anoxic or low oxygen situation, heavily contaminated wounds such as with dirt or rust, and in cases of open fractures with large wounds. In these situations, tetanus bacilli can colonize the skin and mucous membranes, producing neurotoxins that lead to a series of complications. Therefore, anti-tetanus treatment must be conducted for wounds in an anaerobic environment, such as heavily arsenic-contaminated wounds.For routine wounds that are shallow and small, it is sufficient to change the dressing.
Do hemorrhoids bleed?
Hemorrhoids can progress to a stage where there is rectal bleeding characterized by bright red blood that is separate from the stool. This is caused by the severe tortuosity and dilation of the superior hemorrhoidal veins. As the hemorrhoids worsen, congestion and dilation of the hemorrhoidal venous plexus become more pronounced. In the presence of bowel dysfunction and hard stools, the hemorrhoidal venous plexus can be injured, leading to rupture and bleeding. Initially, the bleeding is typically minimal yet frequent. Over time, this may lead to frequent and substantial bleeding. Chronic bleeding from hemorrhoids can cause chronic blood loss anemia, which impacts the physical and mental health of the individual.
Can I take a bath after getting a tetanus shot?
It's not recommended to take a bath immediately after receiving a tetanus shot. First, the wound requiring a tetanus shot may either be deep, heavily contaminated, or relatively large. After receiving a tetanus shot in the buttocks or the deltoid muscle of the upper arm, it is essential to enhance wound dressing changes and keep the wound dry, which is why bathing is not advised. If it's just a simple tetanus injection site, it can generally be exposed to water a few hours later. However, other wounds on the body should be kept dry. Therefore, it is better to take a bath when wounds on other parts of the body have healed well to avoid worsening infections and delaying healing.
What is the function of a tetanus shot?
The function of the tetanus shot is to activate the body's immune system to produce antibodies that can specifically bind to the tetanus toxin, preventing the toxin from binding with nerve cells and causing a toxic reaction that could lead to respiratory arrest, asphyxiation, and endanger life safety. Tetanus infection occurs when the Clostridium tetani bacteria enter the body through mucous membranes following an injury, producing toxins that affect certain muscle groups, such as the jaw and respiratory muscles, thus threatening life safety. Therefore, the role of the tetanus shot is to produce antibodies that bind to the tetanus toxin, preventing it from producing a toxic reaction with nerve cells. Thus, if some wounds are deep and heavily contaminated, it is essential to undergo anti-tetanus treatment.
Where to get a tetanus shot
Tetanus shots can be administered at the emergency department of a regular public hospital. Tetanus toxoid requires a skin test, and if the result is positive indicating an allergy, it cannot be administered; tetanus immunoglobulin does not require a skin test and can be used directly. Alcohol consumption should be avoided before receiving a tetanus shot, as it can affect the results of the skin test, leading to inaccurate indications for the tetanus injection, and impacting its effectiveness. Tetanus shots can be administered at the emergency department of a public hospital.
Can you fart with intestinal obstruction?
Intestinal obstruction is caused by any reason that prevents the passage of intestinal contents. Intestinal obstruction can be divided into acute, partial, and acute complete intestinal obstruction. In complete obstruction, there is a cessation of both gas and feces passage from the anus. Partial obstruction may still allow the passage of gas from the anus, i.e., farting, or a small amount of bowel movement. Acute complete intestinal obstruction is accompanied by abdominal pain and distension, with no gas or feces passing through the anus. Higher intestinal obstructions may also involve nausea and vomiting. Treatment requires gastrointestinal decompression, anti-inflammatory hydration, and if necessary, enema treatment until intestinal function is restored and gas and bowel movements can occur.
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.
Can appendicitis cause vomiting?
Some patients with appendicitis may experience symptoms such as nausea and vomiting. This is because the appendix is located in the lower right abdomen near the ileocecal area, and the appendix cavity is connected to the cecum. The appendix is an independent organ of the human digestive tract. When inflamed, the inflammation can easily irritate the surrounding intestines, causing intestinal spasms and contractions, leading to nausea and vomiting. A typical manifestation of appendicitis is referred pain in the lower right abdomen. Once appendicitis is diagnosed, it is advisable to promptly start anti-inflammatory treatment and, if necessary, proceed with surgical treatment. Appendicitis can range from acute simple appendicitis, which responds well to conservative anti-inflammatory treatment, to acute suppurative or even perforated appendicitis. In these severe cases, it is recommended to perform surgery as soon as possible to remove the appendix and clear the inflammatory secretions, alongside anti-inflammatory treatment.
How long does a tetanus shot last?
After receiving a tetanus shot, it generally lasts for about six months. However, if you are injured again after six months and the wound is heavily contaminated, such as with contaminated soil or rust, and the wound is large and deep, it is advised to undergo tetanus treatment again. The purpose of the tetanus shot is to prevent infection by Clostridium tetani, which is an anaerobic bacterium. It tends to proliferate in anaerobic environments and in conditions of heavy contamination by rust and soil. Therefore, if after tetanus treatment the injury is relatively minor, shallow, and comparatively clean, it is sufficient to clean and dress the wound and keep it dry. If the wound is heavily contaminated, large, and deep, it is recommended to administer the tetanus shot again.
How to administer a tetanus shot if it is negative?
A negative tetanus needle test indicates that the patient is not allergic to the tetanus antitoxin and can continue with intramuscular injections, typically administered in the upper arm or buttock muscles, in doses ranging from 1000 to 3000 units each time. If the infection is severe or the tetanus injection is not timely, the dosage may be appropriately increased, generally by one to two times. The purpose of administering tetanus antitoxin treatment is to prevent infection by Clostridium tetani, an anaerobic bacterium. For patients with deep wounds or heavily contaminated wounds, such as those contaminated with soil or rust, Clostridium tetani can easily colonize. Therefore, for such patients, it is essential to perform tetanus antitoxin treatment while cleaning and dressing the wound.
