Wound Contamination and the Development of Infection

Different types of microorganisms are responsible for wound infections. These microbes can enter and infect the wound in many ways. The post beneath discusses numerous aspects of wound contamination.

The techniques in which micro-organisms can get into a wound are a lot of. These consist of:

- Introduction by means of direct contact. This consists of transfer of microorganisms from equipment or hands of a care giver.

- Via airborne dispersal. This is when microorganisms get introduced to the wound from the surrounding environment.

- By self contamination. This is when microbes physically migrate from a person’s skin or gastrointestinal tract to the wound.

There is no study that identifies 1 of these routes as the most prevalent way of entry for microorganisms into a wound but direct contact by healthcare practitioners and their poor hand washing techniques in the course of pre and post operative phases of patient care is stated to be the most substantial element.

Even so, it really should be noted here that microorganism getting present inside the area of a wound does not mean that wound infection is inevitable and will happen. This occasionally is also beneficial. There are some types of bacteria that via protective colonization create highly specific proteins that kill or inhibit other closely related bacterial species. In other instances specific bacteria produce metabolites and other end goods that inhibit the multiplication of other microorganisms.

Infection development is actually a lot more influenced by the virulence of the organism and immunological status of the patient.

Patients that are most at risk of contracting an infection are those that are becoming treated with long term steroids and those receiving chemotherapy.

Virulence particulars the pathogenicity and invasiveness of the relevant microorganism. There are also other certain elements that have been identified that correlate with infection rates in surgical wounds. These variables contain:

- If there is an existing chronic infection present.

- The duration of the interval of time between skin preparation and actual surgery.

- Nature of the surgery (specifically if it involves the bowel).

- The extent to which tissue has been lost and/or trauma has affected the tissues in the course of surgery.

- If there has been adequate wound drainage.

- If there has been suitable wound management strategies and supplies used.

There are certain wound associated variables that can predispose the development of an infection. These variables include:

- Asepsis techniques had been poorly applied during wound dressing adjustments.

- Devitalised tissue is present within the wound margin, the necrotic tissue or slough. This is significant if the percentage is more than fifty percent.
