Introduction:

Platelet-rich plasma (PRP) has been under development since the 1980s, associated with applications in cardiac, traumatological and dermatological medicine. PRP is an autologous preparation with a platelet concentration above the normal value in peripheral blood that is obtained from its centrifugation following different protocols that were evaluated in different systematic reviews. The Plasma is then activated with thrombin or calcium chloride, or by physical lysis (ultrasound or friz). PRP contains growth factors, cytokines, and adhesion proteins that, when applied to the lesion, favor hemostasis, connective tissue synthesis, and revascularization. The product is applied in solution or gel. Different classifications of the PRP were tried to standardize it without success. The PRP recipe for clinical application was conceptualized, which presented the following characteristics: high platelet values, decreased red blood cell contamination, presence of neutrophils and leukocytes for therapeutic success.

Protocol and cases:

The PRP preparation protocol for single centrifugation for 7 minutes at 1400 rpm with activation through calcium gluconate are presented according to the following ratio: 3 ml plasma/0.4 ml of calcium gluconate. Three cases of diabetic foot ulcers from our institution are reported.

Conclusion:

The PRP does not present complexity in its preparation and application, so it is feasible to perform it in the first level of care that has the material and professional resources with knowledge in the approach to chronic wounds.
