Where There is Smoke, a Lawsuit is Possible

Smoking is known to hinder wound healing, yet most wound care practitioners fail to document any smoking cessation discussion or education.

The daughter of Mrs. Bradley* was barely able to contain herself while giving her deposition. She was sobbing from a place deep in her heart as she retold the story of how her mother lost her leg. Her mother started limping, and they realized she had an “opening” in the skin on the bottom of her foot. Despite treatment, the wound grew in size and became infected. It soon became apparent that she was facing an amputation.


Bacteria and the Wound Bed (Short Video)

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?
