A New Economic Method for Preparing Platelet-rich Plasma.

BACKGROUND: Although platelet-rich plasma (PRP) is nowadays a common method in various medical fields, including cosmetic surgery or dermatology, the expensiveness of the kit for processing is still a hurdle. METHODS: A new unique economic method for preparing PRP was reported. The method consists in a simple modification of a disposable 5-mL syringe that allows insertion into a common centrifuge and positioning of the syringe on the centrifuge so the PRP separates next to the tip of the syringe. Platelet-derived growth factor BB in PRP was measured under anticoagulant dextrose solution A (ACD-A) or heparin as anticoagulant and with or without prostaglandin E1 (PGE1) as a platelet aggregation suppressant. RESULTS: The new method successfully created PRP with high platelet-derived growth factor BB in all conditions, and the highest value was obtained by using ACD-A and PGE1. CONCLUSIONS: The new method is useful, and the use of ACD-A and PGE1 is the most recommended.
