It is vital that all foreign matter and contaminated, devitalized or dead tissue be removed from wounds as first steps in preparing wound bed. The process of removing these substances is what clinicians refer to as wound debridement. All forms of non-viable tissue in wounds are referred to as slough or necrotic tissue. Necrotic tissue has a brown or black coloration while slough is colored yellow and is fibrinous.
There is often an accumulation of necrotic tissue in chronic wounds. This tissue is comprised of exudate, non-viable tissue, necrotic material, and high bacterial levels. The tendency of necrotic tissue to accumulate is higher in chronic wounds. The cause of chronic wounds is venous insufficiency and diabetes among other underlying and uncorrected pathogenic abnormalities. Resolving these systemic issues in full is normally impossible. As such, it becomes important to prepare the bed of the wound in order to facilitate closure of the wounds.
Debridement is made useful and important by several diverse reasons. First, the clinician can assess the status of surrounding tissues and depth of wounds by eliminating devitalized tissue. Secondly, necrotic tissues usually hide any signs of infection in wounds. Also, the physical barrier that necrotic tissue presents supports development and growth of bacteria and also makes the healing process impossible.
Bacterial colonies contained in necrotic tissues create damaging proteases. Proteases negatively affect reepithelialization process and production of granulation tissues. As such, by debriding wounds the likelihood of contamination and destruction of tissue is reduced greatly. It is the elimination of cell debris that contribute to reduced tissue destruction.
There are four main methods of debriding wounds, that is, mechanical, autolytic, surgical or sharp, and enzymatic. Which method is chosen for debriding is made based on several factors. Some of the factors include the type, position, and size of wounds, pain management, time available for the process, moisture levels, and the healthcare setting. The overall condition of the patient is also considered a lot when choosing the methods to be used. Sometimes multiple methods may be employed at once.
Surgical or sharp debriding procedure is the fastest method to use in removing debris and necrotic tissues from wound beds. This approach is most suitable when the clinician cannot tell the depth of wounds due to presence of excess necrotic tissue. It is also the best option for removing infected materials and bones.
The surgical approach has many advantages and benefits associated with it. First, it causes least damage to surrounding tissues. Secondly, minor bleeding that may result helps in repairing wounds because it releases inflammatory mediators like cytokines. The only thing the clinician has to do is to assess the patient and make sure they are suitable candidates for the procedure.
There are many shortcomings associated with this approach too. First, it can only be used on individuals with uncompromised immune systems and no bleeding disorder of any kind. Secondly, it results in transient bacteremia and patients may feel a lot of pain at times. Finally, tendons and nerves get damaged sometimes.
