Antibiotics And Antiseptics To Help Healing Venous Leg Ulcers

Topical antibiotics for prevention of wound infection – Video Abstract 151293

Venous leg ulcers are a type of wound that can take a long time to heal. These ulcers can become infected, and this might cause further delay to healing. Two types of treatment are available to treat infection: systemic antibiotics and topical preparations . Whether systemic or topical preparations are used, patients will also usually have a wound dressing and bandage over the wound. This review was undertaken to find out whether using antibiotics and antiseptics works better than usual care in healing venous leg ulcers, and if so, to find out which antibiotic and antiseptic preparations are better than others. In terms of topical preparations, some evidence is available to support the use of cadexomer iodine . Current evidence does not support the use of honey- or silver-based products. Further good quality research is required before definitive conclusions can be drawn about the effectiveness of antibiotic tablets and topical agents such as povidone-iodine, peroxide-based products and other topical antibiotics and antiseptics in healing venous leg ulceration.

Venous leg ulcers are a type of chronic wound affecting up to 1% of adults in developed countries at some point during their lives. Many of these wounds are colonised by bacteria or show signs of clinical infection. The presence of infection may delay ulcer healing. Two main strategies are used to prevent and treat clinical infection in venous leg ulcers: systemic antibiotics and topical antibiotics or antiseptics.

Recommendations For Specific Categories Of Procedures

Prophylaxis is indicated for all procedures not classified as clean. As previously qualified, certain risk factors justify the use of prophylaxis for clean procedures as well. The following recommendations are provided for specific procedures. A recent quality standards report that further qualifies the strength of recommendations based on the quality of available supporting evidence is also useful.4

Symptoms Of Wound Infections

  • Pus. Pus or cloudy fluid is draining from the wound.
  • Pimple. A pimple or yellow crust has formed on the wound.
  • Soft Scab. The scab has increased in size.
  • Red Area. Increasing redness occurs around the wound.
  • Red Streak. A red streak is spreading from the wound toward the heart.
  • More Pain. The wound has become very tender.
  • More Swelling. Pain or swelling is increasing 48 hours after the wound occurred.
  • Swollen Node. The lymph node draining that area of skin may become large and tender.
  • Fever. A fever occurs.
  • The wound hasn’t healed within 10 days after the injury.

Head And Neck Procedures

For procedures entailing entry into the oropharynx or esophagus, coverage of aerobic cocci is indicated. Prophylaxis has been shown to reduce the incidence of severe wound infection by approximately 50 percent.18,19 Either penicillin or cephalosporin-based prophylaxis is effective. Cefazolin is commonly used. Prophylaxis is not indicated for dentoalveolar procedures, although prophylaxis is warranted in immunocompromised patients undergoing these procedures.

Tips to avoid infection of traumatic wounds:

  • Clean the wound and skin around it as soon as it happens. Use cool boiled water, or drinking-quality water.
  • If you think there are still bits of foreign bodies in the wound, see your surgery nurse or go to your nearest Minor Injuries Unit or A& E to have it professionally cleaned out.
  • If it is a very deep wound, or the edges are very far apart, or you cannot stop the bleeding, go to your nearest Minor Injuries Unit or A& E in case it needs stitches.
  • Use an antiseptic around the wound area to help keep the germs away.
  • Put a clean dressing over your wound to protect it from germs. Do not use gauze or a type of dressing which will stick to the wound. Your pharmacist should be able to advise you if the wound is too big for an ordinary plaster.
  • Bites are very likely to become infected – seek medical advice at the earliest signs of this. If the injury is large, or there are multiple bite wounds, it may be worth having antibiotics ‘in case’. Seek advice straightaway in this case, rather than waiting for signs of infection to develop.
  • Keep a close eye on the wound and seek medical advice if you think infection is developing.
  • Arrange for a tetanus vaccination if needed.

Antibiotics For Dogs: How They Help In Healing Open Wounds

Just like human beings, dogs are also prone to getting infections. Therefore, when a dog hurts themself during a dog fight or any minor accident, veterinarians may prescribe open wound antibiotics for dogs.

Pet parents want the best for their fur friend, and thats why we are to guide you. In addition, you may wish to know more about the types of antibiotics available over-the-counter and how they help in healing open wounds. We have covered all that and more in this in-depth article.

Wound Healing Process And Skin Wound Microbiology

The skin is the largest organ of the HB and represents a defense shield against mechanical, chemical and biological agents, and ultraviolet radiation. Also, it presents excessive water loss, provides hydration and temperature regulation . There are three multi-histological layers of the skin, which are the epidermis, the dermis and the subcutaneous tissue, as well as skin adjuncts , which grow from the profound dermis to superficial epidermal layers .

The wound healing, in any tissue, is a normal biological process and it involves four complex steps: homeostasis/coagulation inflammation, migration and proliferation re-epithelialization and restoration .

The four stages of wound repair.

Wounds can be classified as acute and chronic. Acute wounds represent the injured skin that heals through the regular phases of wound repair in contrast, chronic wounds need a longer healing time. This longer healing time can be usually attributed to many factors, including amplified levels of inflammatory mediators, wound infection, hypoxia and poor nutrition . In the same time it can be dependent on the patients age or underlying comorbidities .

As mentioned, the unlimited development of microorganisms can delay wound closing due to an aggravated and extended inflammatory stage. The problematic pathogens are summarized in Table 1.

Description Of The Intervention

Where an antimicrobial intervention is considered clinically appropriate in the treatment of SWHSI there are two main approaches: an antibiotic may be administered systemically or a topical antibiotic or antiseptic may be applied. Systemic antibiotics affect the whole body while topical treatments affect only a specific area of the body.

Antibiotics are substances that destroy or inhibit the growth of microorganisms . Systemic antibiotic treatments include groups of drugs which share similar modes of action such as penicillins, cephalosporins, aminoglycosides, macrolides and quinolones. Other antibiotics which do not belong to one of these main groups include clindamycin, metronidazole, trimethoprim and cotrimazole.

Topical antimicrobial agents include both antibiotics and antiseptics. Antiseptics are thought to prevent the growth of pathogenic microorganisms without damaging living tissue . Topical applications broadly fall into two types: lotions used for wound irrigation or cleaning, or both, with a brief contact time , and products which are in prolonged contact with the wound such as creams, ointments and impregnated dressings.

Agents used primarily for wound irrigation/cleaning are commonly based on povidone iodine, chlorhexidine and peroxide agents. Less commonly used are traditional agents such as gentian violet and hypochlorites. Longer contact creams and ointments include fusidic acid, mupirocin, neomycin sulphate and iodine .

How Can I Reduce My Risk

Which antibiotic is best for wound healing?

You can reduce your risk of developing cellulitis by:

  • Cleaning your wounds or sores with antibacterial soap and water.
  • Applying an antibiotic ointment on your wounds or sores.
  • Covering your wounds or sores with a bandage to prevent dirt or bacteria from entering the area.
  • Refraining from touching or rubbing your affected areas.
  • Getting medical attention right away for any deep cuts or puncture wounds.

Choosing An Antibiotic For Skin Infections

A new study in the New England Journal of Medicine on treatment of skin infections compares treatment with trimethoprim sulfamethoxazole or clindamycin. Surprisingly, both worked equally well in this 524 patient study, curing about 89% of outpatients with uncomplicated skin infections cellulitis and abscesses, so the authors appear to encourage use of one of these drugs because they are better at treating MRSA than are currently recommended antibiotics.

I think this is a bad ideait fuels the escalating use of broader spectrum antibiotics with more side effects, at a time when antibiotic development is languishing. It also encourages the just in case type of response, rather than prescribers actually thinking about what kind of bacterial infection the patient might have. The authors also used a 10-day course of treatment, when expert recommendations are encouraging 5-7 days treatment to try to reduce risks to patients.

Skin infections are a huge problem. They resulted in 14.2 million outpatient visits in 2005 , and 850,000 hospital admissions, according to the article.

While this study adds important information comparing two commonly used drugs for treating skin infection, it should not result in a change in current antibiotic treatment recommendations.

The technical details

The study was well-done, in that it was randomized and double-blinded, meaning that neither the patient nor the investigator knew which treatment the patient was receiving.


Type Of Antibiotic For Wounds In Dogs

Just like human beings, dogs can get infections too. The infection can put a dog through immense stress and discomfort. If the doctor does not treat the infected wounds, the condition can become life-threatening.

When a dog is in pain, they will limp and whine. The pain may be unbearable for your fur friend, and they might lose their appetite.

Make sure you have all the supplies to take care of the wound. It would be best to have clean towels, clippers, warm water, a water-based lubricant, and some ointment.

Since the wound is fresh, your dog needs medical attention. When the wound is fresh, you are in a dilemma about giving antibiotics or using whatever is available at home. Heres something you need to know: your doctor knows the best.

Your dogs veterinarian may prescribe open wound antibiotics for dogs to prevent further infection. Here below are various types of antibiotics that commonly used by veterinarians which summarized by the team.

1. Oral Antibiotic

Oral antibiotics are the most common type of antibiotic, including Amoxicillin, Doxycycline, and Erythromycin. Usually, veterinarians prescribe Amoxicillin for dog wounds, and the treatment lasts up to 7 to 14 days.

However, if the infection or dog bite is deep and lethal, the veterinarians suggest oral open wound antibiotics for dogs.

The best way to give oral antibiotics is to mix them with food.

How Antibiotics Can Be Given To Horses

Antibiotic drugs need to reach the infected site at concentrations high enough to do the job. If the infection is on or near the surface of the skin, this is easier. Scratches and wounds, for example, can often be readily treated just by cleaning the area and removing contaminated or devitalized tissue. A topical antibiotic may then be applied. For internal infections, the antibiotics must be delivered so that there is a therapeutic concentration in the blood and at the site of infection.

A number of antibiotics can be administered orally, in pills or pastes. Often, the medication must be given two or three times a day, for five days or a week at minimum. Sometimes that treatment needs to go on for months. Usually only one antibiotic is prescribed. In less common cases, two or even three at the same time may be necessary. Some antibiotics are not given orallybecause they are destroyed in the gastrointestinal tract, they are not sufficiently absorbed through the gut wall, or the drug is cleared by the liver too rapidly.

Drugs that are injected into muscle tissue or infused directly into a blood vessel reach a higher concentration in the bloodstream and act more quickly. But administering antibiotics by these methods can cause irritation and, in some cases, risks serious side effects. So your veterinarian will determine not only what is effective against the bacteria but what is safe for your horse.

Prophylaxis is not indicated for cutaneous and superficial soft tissue procedures. For patients with two or more significant risk factors , prophylaxis is acceptable but not strongly indicated. Traumatic wounds require consideration of the status of the patient’s tetanus vaccination. Although a single dose of antibiotic is acceptable, mechanical cleansing and adherence to guidelines for open management of wounds created more than 12 hours before treatment are the essential elements of prophylaxis.

Side Effects And Risks Of Antibiotics

Antibiotic use often carries with it many side effects and your doctor probably wont discuss these risks with you.

Most antibiotic drugs have significant negative side effects, which can include: diarrhea, hives, yeast infections, upset stomach, nausea, vomiting, depressed white blood cell counts , rashes, and more. Consult your physician if you are pregnant or breast feeding. Many people can not take antibiotics because of the severe side effects. is a free, independent drug safety website where you can research your antibiotic for ALL of the side effects that actual people are experiencing. You can also report your side-effects. .

If you are pregnant you should also strongly consider alternatives to antibiotics because of health issues correlated to the developing child.

Parents should be especially cautious using antibiotics on children as I believe they can, especially with overuse, contribute to many chronic illnesses. Why? Antibiotics will kill off many of the good or friendly bacteria inside the intestines along with the bad bacteria of the infection. This disruption of the natural bacteria balance in the body can cause intestinal problems but importantly, they also weaken the bodys immune system, thus increasing the chances of getting re-infected later.

You have an entire army of bacteria that work to keep you safe and healthy, and antibiotics kill both the bad and the good bacteria leaving your body compromised.

Can Leg Ulcers Be Prevented

To prevent and promote healing of ulcers:

  • Avoid injury, particularly when pushing a supermarket trolley. Consider protective shin splints.
  • Walk and exercise for at least an hour a day to keep the calf muscle pump working properly.
  • Lose weight if you are overweight.
  • Check your feet and legs regularly. Look for cracks, sores or changes in colour. Moisturise after bathing.
  • Wear comfortable well-fitting shoes and socks. Avoid socks with a tight garter or cuff. Check the inside of shoes for small stones or rough patches before you put them on.
  • If you have to stand for more than a few minutes, try to vary your stance as much as possible.
  • When sitting, wriggle your toes, move your feet up and down and take frequent walks.
  • Avoid sitting with your legs crossed. Put your feet up on a padded stool to reduce swelling.
  • Avoid extremes of temperature such as hot baths or sitting close to a heater. Keep cold feet warm with socks and slippers.
  • Consult a chiropodist or podiatrist to remove a callus or hard skin.
  • Wear at least Grade 2 support stockings if your doctor has advised these. This is particularly important for the post-thrombotic syndrome, leg swelling or discomfort, and for long-distance flights.
  • Have a vascular ultrasound assessment and consult a vascular surgeon to determine whether any vein treatment should be carried out.
  • Horse chestnut extract appears to be of benefit for at least some patients with venous disease.

What Tests Will Be Done To Diagnose Cellulitis

In most cases, your healthcare provider wont conduct any tests. However, if youve got a severe case of cellulitis, your healthcare provider may recommend tests to make sure the infection hasnt spread to other parts of your body.

These tests may include:

  • Blood test. A blood test will confirm whether the cellulitis infection has spread to your blood.
  • Skin test. A skin test will identify the type of bacteria responsible for your cellulitis, which helps your healthcare provider prescribe the most appropriate antibiotic.
  • Bacterial culture. A bacterial culture will identify the type of bacteria responsible for your cellulitis.

How Do I Know If I Have Necrotizing Fasciitis

Wound Care – Preventing Infections

When a person has necrotizing fasciitis, they may experience severe pain that worsens with time and experience flu-like symptoms. They may also become dehydrated. A person with these symptoms should seek immediate medical attention. Without prompt treatment, the wound will swell and may become purple. Later, blisters will develop that oose dark fluid. This is a sign of dying tissue or necrosis. The infection will then spread beyond the initial wound site and become life threatening.

What Defines A Surgical Wound Infection

A surgical wound/site infection is defined by the following criteria. Infection must occur within 30 days of the surgical operation, and at least one of the following must occur:

  • Purulentdischarge from the surgical site
  • Purulent discharge from wound or drain placed in the wound
  • Organisms isolated from the aseptically obtained wound culture
  • Must be at least one of the signs and symptoms of infection pain or tenderness, localised swelling, or redness/heat.

Other signs of wound infection include:

  • Delayed healing not previously anticipated.
  • Discolouration of tissues both within and at the wound margins.
  • Abnormal smell coming from the wound site.
  • Friable, bleeding granulation tissue despite appropriate care and management.
  • Lymphangitis, a red line originating from the wound and leading to swollen tender lymphglands draining the affected area.

Surgical site infections do not include a stitch abscess, episiotomy infection, newborn circumcisionscar, or infected thermal burn wound.
