Your Diabetic Foot Treatment Team: Why they should obtain wound cultures to determine if any dangerous organisms such as MRSA are present.

In these discussions, we discuss each of the 7 essential skills that your diabetes treatment team must use in order to help you prevent an amputation related to your diabetes.

Today we will discuss essential skill number three
3. Obtain wound cultures to determine if any dangerous organisms such as MRSA are present. Use appropriate culture techniques.

The primary reason that a person ends up with a diabetic foot amputation is because of a poor blood supply and uncontrolled infection. When ever a diabetic foot ulceration (open sore) develops, bacteria that is normally growing on the skin will live within the wound.

Doctors call this colonization. Colonization is what a normal process. Your entire skin is colonized with bacteria. In most instances, colonized bacteria do not cause harm or disease. The difference between colonization and infection is that one is a normal process and another causes harm.

One definition of infection is “to do well in internally endoparasitically as opposed to externally.” A parasite always lives at the expense of its host. When bacteria in an open wound on a diabetic foot begins to invade the tissue, rather than just living on the surface a diabetic foot infection begins.

In order to remove any infecting bacteria it is important to differentiate the organism causing the infection from other organisms that are normally growing on the skin and may not be causing any harm. The most reliable way to differentiate these two groups of bacteria is by obtaining a wound culture.

A wound culture is a process whereby a doctor obtains a sample of infectious material and places it in an artificial medium, where it will grow. The basic idea, is to take samples of the bacteria in the wound and transfer them to a petri dish and place them in an incubator. The bacteria will then start to grow.

If several samples of different antibiotics are placed with in the petri dish and marked, the bacteria will not grow, near the antibiotics to which they are susceptible. This is how doctors determine which antibiotics are likely to kill the bacteria and remove the infection from a diabetic foot.

In order to remove an infection, you must take the appropriate antibiotics. This can only be determined accurately with a culture.

Not only is it important to take a wound culture and make sure that a diabetic foot infection is being treated correctly, timing is also important. It takes a couple of days for cultures to determine which antibiotics are going to be effective. Because of this, most diabetics with an infected open sore will be started on antibiotics that are probably going to work. It is critical that the wound culture is taken before these antibiotics are given. Once antibiotics have been given, but when cultures become unreliable.

If the diabetic foot infection is not treated with the right antibiotics, they can take much longer to remove the infection. Most antibiotics are processed and removed from the bloodstream by the kidneys. Diabetics are at high risk for kidney damage. Often times when someone who is a diabetic takes antibiotics for a long period of time, they can damage the kidneys further. This can lead to complete renal failure, which places the patient on dialysis. A diabetic patient who has had kidney failure will die without dialysis to remove impurities from the blood.

This being the case is understandable why it is important to make sure that any antibiotics taken are going to the effective and only administered for the shortest period of time.

Whenever you go to the emergency room or see a doctor because you believe that you have an infected diabetic foot ulceration, you must insist that cultures are obtained before you start any antibiotics. This will help speed your healing, minimize the chances of any kidney damage, and reduce the risk that you will end up with a diabetic leg amputation.

Keep in mind that early treatment is key. If you believe that you are developing a diabetic foot infection, you should seek treatment immediately. No matter what time of day or night. You should call your treating physician and explain to them, what is happening so that treatment can begin right away.

This is why it is so important for everyone with diabetes to have a doctor that they feel they can call at any hour to discuss their concerns. In most cases, a short discussion can help you determine whether or not, you need to get out of bed and go to the emergency room or if this is a smaller issue, or if it can wait until the next day.

No issue is too small to discuss with your diabetes doctor. Diabetics are at extraordinary risk for having what seems like a minor problem end up as a life-changing amputation. Amputations are preventable.
