What are the characteristics of wound infection? What can be done to prevent wound infection?

Preamble: If we have a wound on our body, there is a high chance that it will be infected by bacteria. Wounds that become infected after bacteria may be difficult to heal and there may be some inflammation.

If it is severe, septic shock may occur, which is life-threatening. Therefore, when we are injured, we must bandage the wound in time to prevent infection. <>

1. Symptoms of wound infection

There is a distinction between acute and chronic wound infection, and it can also be divided into local infection and systemic infection depending on the site of infection. If the wound is infected, it may be characterized by local redness, swelling, pain, foul smell, and even wound healing. If the wound is infected, the patient's wound discharge will increase, the wound will be red and swollen, and the pain will be felt.

If the whole body is infected with **, the condition will be more serious, and the patient will have chills, fever, and elevated white blood cells. Everyone must go to the hospital in time after this situation occurs. <>

After an injury, we can choose to inject tetanus antitoxin, a substance called tetanus bacteria, which invades the wound in the body and grows and multiplies there, causing a specific infection. Tetanus antitoxin injections are effective in preventing wound infections. After the injury, it is necessary to ensure daily sleep time to prevent overexertion and affect the healing of the wound.

Make sure that the environment in which you live is clean and tidy, and disinfect and clean up every day. Used quilt covers, bed sheets, etc. should be washed separately, and exposed to the sun for 6 hours after cleaning to achieve the effect of full disinfection and sterilization, and the wound site should be washed and changed frequently. You can't touch the wound with your hands, there are a lot of bacteria on your hands, and it is very easy for these bacteria to enter the inside of the wound.

The wound area should not be stained with water or dust. Only by doing these things well can our wounds heal in time.

Characteristics of wound infection: it is also red, swollen, hot, painful and other manifestations. The surface can be cleaned with clean saline and then wiped with alcohol and iodophor.

If the wound is infected, it will lead to itching, and the surrounding symptoms of redness and swelling will also appear, if you want to prevent wound infection, you must take care of it in time, and then you should also change the dressing regularly to keep the wound clean and hygienic.

If the wound is caused by the injury, the wound is usually irregular, or bleeds a lot, or is heavily contaminated. To prevent infection, we must first disinfect with hydrogen peroxide iodine to remove dirt and dead tissue. Debridement and suturing of the wound are then performed.

Pay attention to local cleanliness and hygiene, and avoid scratching, squeezing and rubbing. Avoid moisture and keep the area dry.

Wound infection is mainly manifested as redness, swelling, heat, and pain. The prevention of wound infection can promote the early recovery of wounds, and the prevention of infection should be achieved in a timely manner with tetanus vaccination, medical staff strictly follow the principle of sterility to operate, and patients should be cleaned daily. The patient's own immunity is also very important to resist bacterial infection, so eat more fresh fruits and vegetables, and strengthen physical exercise without affecting the wound to enhance the body's immunity.

Wound infection generally has the following symptoms: first, there may be redness, swelling and pain of the wound, and it may be accompanied by suppuration of the wound site, if this situation occurs, it is necessary to carry out wound debridement and disinfection treatment in time, and use antibiotics at the same time.

Second, there may be pus, water, itching, redness and swelling, and the wound can be cleaned with iodophor every day and bandaged to prevent reinfection. The third is that when it is more severe, there will be a large area of ulceration.

Wounds infected by the virus have no obvious characteristics, and are also red, swollen, hot, and painful. In order to determine whether the wound is infected by the virus, it is necessary to draw blood for laboratory tests, which generally show a significant increase in lymphocytes, and at the same time, combined with the patient's relevant viral exposure history and other comprehensive evaluation judgment.

The main bacteria that cause wound infections are tetanus bacillus and Mycobacterium avium.

1. Tetanus is an acute and specific infection caused by tetanus bacilli invading the wound and secreting toxins, which is mainly manifested as continuous contraction and paroxysmal spasm of the whole body or local muscles.

Tetanus bacillus is a gram-positive anaerobic bacillus that is widely found in dirt and feces and is highly resistant to the environment. During trauma, it can contaminate deep tissues, if the wound is deep, and there are necrotic tissues, ischemia and hypoxia, which forms an environment suitable for the growth and reproduction of bacteria.

2. The symptoms of disseminated disease caused by Mycobacterium avium complex are fever, anemia, thrombocytopenia, diarrhea and abdominal pain, that is, its characteristics are similar to that of Whipple blood.

Cultures of bone marrow or small bowel biopsy specimens can confirm the diagnosis, although bacteria can also be found in stool and respiratory specimens, but these can only indicate bacterial growth and do not represent a true disease, antimycobacterial drugs combined with ** can reduce bacteremia and temporarily improve symptoms, but there is no truly successful ** regimen**, and the prognosis is very poor.

You should pay attention to anti-inflammatory, take anti-inflammatory drugs during the recovery process, match a light diet, drink plenty of water, and pay attention to rest, so that you can recover slowly.

You should pay attention to your diet, improve your body's immunity, don't eat seafood, pay attention to the cleanliness of the wound, disinfect it regularly, apply some ointments, and pay attention to the healing of the wound.

I think we should pay attention to the problems of diet, work and rest, life, spirit and behavior.

If the wound infection is only local symptoms of redness and swelling and no other changes, a wet compress with alcohol can be applied after routine local disinfection, or oral antibiotic medication** can be used. If the wound is suppurated**, the local double-needle suture should be removed and the pus should be squeezed out of the abscess cavity. This is followed by drainage with sterile gauze strips, regular dressing changes, and oral antibiotics.

The healing time of wound infections will be significantly longer. Wound infection is manifested by swelling and pain of the wound surface, and the local ** temperature rises. Patients are advised to go to the hospital promptly after infection**.

There are many ways to treat wound infection, mainly to actively take antibiotics, and at the same time to keep the wound clean and dry, if there are other uncomfortable symptoms, after the local drug can be eliminated before you can continue to accept**, if there are no other uncomfortable symptoms, it is recommended to take oral antibiotic drugs**, so as not to make other bacteria invade and cause infection.

The recovery time of wound infection is closely related to whether there are infected bacteria at the wound and whether there is pathological damage. If it is a wound infection, it is necessary to go to the hospital in time**, not delay**. It may be that there is a purulent infection around the wound, which will cause the pus around the wound to spread further inside, and may affect the healing of the wound.

During the recovery period of wound infection, it is necessary to rest more and not exercise vigorously. During the recovery period of wound infection, it is still necessary to follow the doctor's instructions, and care should be taken to avoid infection of the injured part during the recovery period. If the wound infection is manifested locally as red and swollen, and the wound infection occurs in the muscle area, it is relatively difficult to recover, and the small wound is easy to treat, but if it is a large or deep wound, if it is not treated properly, infection and pus will appear, resulting in excessive pus accumulation and necrosis of the wound.

At this time, special attention should be paid to debridement and antibacterial and anti-inflammatory work.

It is necessary to disinfect and sterilize with alcohol immediately, go to the hospital for treatment in time, and be sure to avoid water to prevent the problem from becoming more serious.

If the infection of the wound is not serious, but there are symptoms of redness, swelling and exudate, then you can use normal saline to wash it every day, after cleaning, apply iodine to disinfect and reduce inflammation, and then wrap it with clean gauze.

It can be washed with saline, then disinfected with iodine and wrapped in gauze to avoid infection. If the wound is suppurated, debridement and then sterilization and dressing are required.

The main key to whether the trauma causes future infection lies in two points: first, whether the treatment of the injured area is timely and correct, and second, whether the nutritional status is appropriate. What can be done to prevent wound infection?

Here are some ways to prevent wound infection. It's good to find out. Ways to prevent it.

1. Wound treatment must be done as soon as possible, as soon as possible, and thoroughly. Once we are injured, we should immediately cover the wound with sterile gauze, dressings, bandages, etc., the purpose of this is to reduce the contact of the wound with the air, so as not to allow airborne bacteria to invade the wound. If you don't have a sterile gauze bandage at home, you can use a clean cloth instead.

If the wound is bleeding, it should be compressed and bandaged to prevent the wound from bleeding. If the wound is too large or deep, bleeding is excessive, and there is a foreign body on the wound, it is necessary to send the wound to the hospital immediately after simple first aid, and let the surgeon treat the wound to debride and disinfect the wound to remove the contaminated tissue or foreign body. Ways to prevent it.

Second, it is also very important to pay attention to nutritional status in daily nutrition. If the whole body is malnourished, suffering from anemia, vitamin deficiency, etc., this will directly affect the resistance of the wound and the healing ability of the wound. The resistance is too low, which in turn can lead to the wound not being healed for a long time, and the accumulated blood, foreign body and necrotic tissue around the wound can not only cause the wound inflammatory reaction, but also provide favorable conditions for the reproduction of bacteria in the wound, followed by continued infection and suppuration.

Common pathogenic bacteria that cause wound infection are: Staphylococcus aureus, Staphylococcus epidermidis, Pseudomonas aeruginosa, Enterococci, Escherichia coli, Pseudomonas aeruginosa, etc.

Pseudomonas aeruginosa, Escherichia coli, Mycobacterium tuberculosis, Streptococcus, Staphylococcus aureus, spores, fungi, Bacillus anthracis, Tetanus bacillus, etc.

Due to the widespread use of antibiotics, the bacterial ecology has changed, and before the late 60s, surgical infections were mainly gram-positive bacteria, and in the past 10 years, gram-negative bacteria (Escherichia coli, Pseudomonas aeruginosa, Klebsiella, etc.).

People's Military Doctor" 1, purulent infection, such as boils, carbuncles, erysipelas, acute mastitis, acute appendicitis, etc. Common pathogenic bacteria are staphylococcus, streptococcus, Escherichia coli, etc. Its characteristics are:

The same pathogenic bacteria can cause several different purulent infections, such as Staphylococcus aureus can cause boils, carbuncles, abscesses, wound infections, etc.; Different pathogenic bacteria can cause the same disease, such as Staphylococcus aureus, Streptococcus and Escherichia coli, which can cause acute cellulitis, soft tissue abscess, wound infection, etc. There are common features of purulent inflammation, i.e., redness, swelling, warmth, pain, and dysfunction. There are also commonalities in prevention and control.

2. Specific ** infection: such as tuberculosis, tetanus, gas gangrene, etc.

Whenever someone is injured, the wound should be treated immediately to reduce the pain and harm suffered by the injured person, shorten the wound healing time, and in some cases, these first aid measures can even make the difference between life and death of a person. However, incorrect first aid measures can make the wound worse, a common example being an infection during first aid treatment. Therefore, it is essential to learn first aid knowledge.

What is Infection? Infection refers to the local tissue and systemic inflammatory response caused by the invasion of pathogens such as bacteria, viruses, fungi, and parasites into the human body. Normally, your whole body can protect you from these bacteria, however, if there is a wound in the breakage, the infection will threaten you and become a more serious condition.

What happens if the wound is infected? Wound infection slows down the healing time of the wound and, in extreme cases, causes substantial damage to the injured person's body, and may eventually lead to death. Knowing what happens when a wound is infected, you must learn 1. Wash your hands.

Hands are the dirtiest part of the human body, and it is very easy to infect the wound by touching the wound directly with your hands, so you must wash your hands before first aid treatment for the injured. 2. Wear gloves. Even after washing your hands, it's a good idea to wear a clean pair of plastic or rubber gloves, as a good first aid kit will always contain these gear.

3. Use clean raw materials (known to everyone on earth). Use only clean bandages and padding with waterproof packaging. Keep your first-aid equipment clean at all times, such as needles or scissors, and disinfect them with potions before and after use.

4. Clean the wound. The first thing you have to do in first aid is to clean the wound, first, use warm water and soap to clean the wound with sand, dust, debris, etc., and then use some antiseptic medicine such as antibiotic ointment, or at least alcohol, to disinfect the wound, which may be a bit stinging, but it is better than letting the wound become infected. 5. The wound should be bandaged firmly.

Even if the wound has been sealed, it can still become infected, so be sure to completely cover all parts of the wound and dress it firmly. The above is how to prevent wound infection first aid common sense, there may be incomplete, welcome to point out.
