Preventing Infection on An Open Wound

Fact Checked

A wound is a break in the skin that can become infected if it is not treated and cleaned properly. While a minor wound can be negligible in many cases, it can pose a major risk to individuals with conditions that prevent the efficient healing processes to take place. Individuals with a weak immune system, diabetes mellitus, cancer, kidney and lung condition tend to show a slow response to wound healing. In other cases, objects that are not removed from inside the wound like broken glass can also delay healing and increase the chances the wound becomes infected.

Diagnosing an infected wound

Most of the time a victim does not need to go through a diagnostic examination to know that a wound is infected. By making a simple assessment of the wound, a victim can recognize signs that can indicate the presence of infection. A warm, tender and swollen wound is likely to be infected and the signs of a fever also collaborates the presence of an infection. In some instances blood and pus may also come out of the wound and a foul odor may also be present.

Cover the wound to prevent infection

Infection is often apparent a few days after sustaining the wound. It is important to check the wound from time to time even while it is already being treated. If the wound is covered with a bandage or gauze, make sure to change the dressing every day. Slowly remove the gauze and look at the wound closely looking particularly for signs of fluid discharge from the wound. If a sign of infection is apparent, find the closest lymph nodes to the wound area. This is where the bacteria is trapped when the body’s immune response takes action. If the nodes are swollen and tender you can confirm that the infection is present and seek medical attention.
