Platelet Gel
From Noblood
Contents |
Autologous platelet gel is a substance that is created by pheresing platelet-rich plasma (PRP) from the patient's blood prior to surgery and combining it with thrombin and calcium to form a coagulum. This coagulum or "platelet gel" has an extremely wide-range of clinical healing uses from dental surgery to orthopedics and plastic surgery. Autologous platelet gel should ONLY be prepared by or under the direction of a certified and (or) licensed clinical perfusionist.
Primary component of origin
Percent of component
Percentages will vary depending upon size and condition of patient, process used to make the gel, as well as for which particular medical procedure it is needed. Below is just one example:
- The PRP, comprises of approximately 10% of the total blood volume withdrawn and has platelet counts of 500,000-3,000,000/mm³. This is the solution used to make the Platelet Gel.
Production
Platelets are separated from 30 mL to 55 mL of whole autologous blood collected from a patient preoperatively, preferably 45 minutes to one hour before induction of anesthesia. The blood is separated via a single, 12-minute centrifuge spin, which collects approximately 6-mL of platelet-rich plasma (PRP) and 30-mL PPP per 55 mL of separated whole blood.
Medicinal Value
Treating diabetic ulcers, bone augmentation and fusion, surgical dehiscience, venous stasis uclers as well as to improve granulation formation and wound closure; also used beneficially on burns, neurosurgery, ob-gyn, oral maxillo facial, orthopedics, plastic and cosmetic surgery, as well as other surgical procedures where acute bleeding or fluid discharge may be prevalent.
