Platelet-rich plasma (PRP) is plasma with many more platelets than what is typically found in blood. A high-quality PRP system can concentrate platelets 6-10 times greater than what is usual in blood.
The platelets contain growth factors such as platelet-derived growth factor, epidermal growth factor (EGF), fibroblast growth factor, and connective tissue growth factor. Blood is drawn from the patient and is then placed in a centrifuge to spin at high speeds. This allows the platelet-rich plasma to separate from the blood.
In the case of wound care, PRP is injected directly into the affected area. Targeted delivery of these growth factors to injured tissues can accelerate and promote the healing cascade within your body.
PRP treatments for wound care are becoming more common and a viable choice amongst patients who are looking for shortened hospital stays, cost efficient/shortened treatments, and an improvement in one’s quality of life.
The anti-inflammatory properties of PRP play an important role in wound healing. PRP not only releases large quantities of platelet growth factors to enhance the healing process, it also possesses antimicrobial properties that may contribute to the prevention of infections.
Leukocytes are at high levels in PRP because the density of leukocytes are similar to that of the platelets. During the centrifuge process both platelets and leukocytes drop into the same layer of the centrifuge tube. Advantages of PRP for wound treatment include the biocompatible safety of using the patient’s own blood. As well as the significant clinical effectiveness and simple preparation, PRP treatments have become an ideal therapy in the treatment of chronic skin related wounds.
