What are the signs and symptoms of a wound infection?
If the wound begins to drain yellow or greenish fluid (pus), or if the skin around the wound becomes red, warm, swollen, or increasingly painful; a wound infection may be present and medical care should be sought.
Any red streaking of the skin around the wound may indicate an infection in the system that drains fluid from the tissues, called the lymph system. This infection (lymphangitis) can be serious, especially if it is accompanied by a fever. Prompt medical care should be sought if streaking redness from a wound is noticed.
How are puncture wounds different?
A puncture wound is caused by an object piercing the skin, creating a small hole. Some punctures can be very deep, depending on the source and cause.
Puncture wounds do not usually bleed much, but, treatment is necessary to prevent infection. A puncture wound can cause infection because it forces bacteria and debris deep into the tissue, and the wound closes quickly forming an ideal place for bacteria to grow.
For example, if a nail penetrates deep into the foot, it can hit a bone and introduce bacteria into the bone. This risk is especially great if an object has gone through a pair of sneakers. The foam in sneakers can harbor bacteria (Pseudomonas) that can lead to serious infection in the tissues.
First aid for puncture wounds includes cleaning the area thoroughly with soap and water. These wounds are very difficult to clean out. If the area is swollen, ice can be applied and the area punctured should be elevated. Apply antibiotic ointments (Bacitracin, Polysporin,
Neosporin) to prevent infection. Cover the wound with a bandage to keep out harmful bacteria and dirt.
Cleanse the puncture wound and change the bandage three times a day, and monitor for signs of infection (the same signs as above in the cuts section). Change the bandage any time it becomes wet or dirty.
People with suppressed immune systems or any particularly deep puncture wounds should be seen by a health care
practitioner. If it is difficult to remove the puncturing object, it may have penetrated the bone and requires medical care.
Most puncture wounds do not become infected, but if redness, swelling or bleeding persists, see your health care
practitioner.
Puncture wounds to the feet are a particular concern. Wear shoes to minimize the risk of a puncture wound from a nail or glass, especially if
the affected person has diabetes or loss of sensation in the feet for any reason.
Additional common causes of puncture wounds can include animal or human bites, or splinters from wood or other plant material, which carry a high risk of infection and should be treated by a physician.
Staphylococcus or Staph is a group of bacteria that can cause a multitude of diseases. Staph infections can cause illness directly by infection or indirectly by the toxins they produce. Symptoms and signs of a Staph infection include redness, swelling, pain, and drainage of pus. Minor skin infections are treated with an antibiotic ointment, while more serious infections are treated with intravenous antibiotics.
A keloid is a scar that doesn't know when to stop. When the cells keep on reproducing, the result is an overgrown (hypertrophic) scar or a keloid. A keloid looks shiny and is often dome-shaped, ranging in color from slightly pink to red. It feels hard and thick and is always raised above the surrounding skin.
There are millions of dogs living in the United States, and thus many cases of dog bites. Annually, hundreds of people seek emergency medical care for dog bites. Treatment for a dog bite depends on how deep the injury is and the amount of tissue damage. Dog bites can be prevented by employing preventative measures.
Tetanus is an often-fatal disease caused by nerve toxins produced by the common bacteria Clostridium tetani. In a seven-day period after infection, a person experiences muscle spasms, restlessness, headache, irritability, then lockjaw, and the lungs stop functioning. Tetanus is treatable with antibiotics and drainage. Sedation is often give to stop muscle spasms.
There are several bones in the foot, and these bones can be broken (fractured) in a variety of ways. Falling from heights, dropping heavy objects on the foot, or stress fractures from running or walking. Treatment of a broken foot depends on what bone in the foot is broken.
Necrotizing fasciitis is also known as a flesh-eating bacterial infection, Fournier's gangrene, suppurative fasciitis, and necrotizing cellulitis. The disease is occasionally caused by fungi, but most cases are caused by bacteria that enter the skin through insect bites, cuts, puncture wounds, or surgical incisions. Symptoms include pain, redness, swelling, fever, chills, skin ulceration, bullae formation, black scabs, gas formation, and fluid draining from the site of infection. Treatment involves hospitalization, the use of intravenous antibiotics, and debridement of the necrotic tissue.
The most common cause of a black eye is due to an injury to the face or head. Most black eye injuries are minor and heal on their own, however, some may lead to significant injury. In addition to trauma to the face, cosmetic surgery can cause a black eye(s) as a side effect. People should be aware of the situations in which medical care should be sought immediately for a black eye.
The hand has several bones to include the wrist, palm, and fingers. Fingers are the most commonly injured part of the hand. The most common causes of broken fingers are a traumatic injury to the finger or fingers such as playing sports, injury in the workplace, falls, and accidents. Treatment for a broken finger may be as simple as buddy taping the broken finger to the adjacent finger, or if the fracture is more serious, surgery.
First aid is a complicated subject and it is situation-specific. First aid is the help and medical assistance that someone gives, not only to an injured person, but to a person who is sick. Preparedness is a key element of first aid, like having basic medical emergency kits in your home, car, boat, or RV. Cuts, puncture wounds, sprains, strains, nosebleeds are one type of injury that may require first aid; heart attacks, strokes, seizures, and heat stroke are examples of more critical first aid emergencies.
Natural diasters such as a hurricane can take a toll on family, friends, and neighbors. Both physiological and psychological stresses can be devastating. Learn how to prepare for a hurricane like food storage, safe water, first aid measures, cleaning mold, wearing protective gear, preparing for electrical hazards, avoiding carbon monoxide, avoiding physical injuries and hazardous materials, preventing drowning, reducing the risk of thermal stress, and preventing fatigue related injuries.
