Bacteria and the Wound Bed (Short Video)

Monday, May 25th, 2009

We have bacteria on our skin. As Donna Sardina RN states, “Every Square Inch of our body has 32 Million Bacteria on it”. Some of the bacteria on our skin and some of it is bad and when a wound is developed, that bacteria enters the wound and eventually competes for the oxygen and nutrients on the cellular level.

Temperature Effects on Wound Healing

Sunday, May 3rd, 2009


As you may know, the loss of moisture from any surface by evaporation is accompanied by cooling of the surface. Therefore as wound tissues lose moisture a cooling effect occurs in the wound. Cells and enzymes function optimally at normal body temperature. A temperature drop of just 2 degrees C is sufficient enough to affect the biological healing process.

Did you know that when a wound dressing is changed can drop a wound base temp for up to four hours before it returns to normal? Think about that when considering healing times as well as prepping your patient for a dressing change next time.

Another thing to consider is that when tissue cooling occurs it can lead to an increase risk of infection by causing vasoconstriction and increasing hemoglobin’s need for oxygen. This results in decreased oxygen available for neutrophils which fight infection.

So how is Temperature effecting your patient’s wound healing rates? Are you considering this variable when approaching the care you deliver to the patient?
