|[en] GPS ; PRP ; platelet|
Recently, several researches, essentially in vitro, demonstrated the positive effects of platelets on healing process of different tissues: bones, muscles and tendons.
The aim of this study is to compare the obtained platelets concentration between the new GPS™ III and GPS™ II.
Two blood samples of 52 mL were taken in 5 volunteers and transferred respectively in both GPS™ II and GPS™ III. These devices were centrifuged at 3200 RPM during 15 min. The platelet-rich plasma (PRP) was thus collected and transferred in 6 mL test tubes.
Cells count was done using an analyser ABX Micros 60.
Results and conclusion:
Platelets concentrations were more important from 6.2 up to 9.2 times with GPS™ II and from 7.3 up to 8.3 times with GPS™ III compared to blood samples. Efficiency of the collected platelets was around 92% for GPS™ II and 96% for GPS™ III. Both techniques made it possible to collect platelets but, unfortunately, also a lot of red and white blood cells.
None of these parameters showed any significant difference (p>0.05).
Conflicts of interests:
The 10 devices GPS™ II and GPS™ III were provided gracefully by the firm Biomet Biologics TTC.
