Abstract:

【Abstract】 Objective To investigate the effect of platelet-rich plasma (PRP) on treatment for hard agglut wounds. Methods From October 2010 to March 2012, 32 patients with chronic wounds were received the treatment with PRP gelatin gel. The PRP preparation derived from 30 mL of venous blood was placed on the wound,and then the wound was covered with Vaseline gauze and sealed up with a kind of medical membrane for 7 days before next dressing change. Three times was one course. The wound healing was evaluated by observation of wound surface and measurement of wound area before and two months after treatment. Results The wounds had an obvious improvement with fresh tissue after one treatment course, without further exudate. The wound volume changed from 9.5±4.7 mL (V1, before the treatment) to 1.7±0.9 mL (V2, after two months of treatment) (P<0.05). Among 32 patients, the cure rate was 31.2% and the effective rate was 93.8%. Conclusion Platelet-rich plasma is an effective and practical method in treatment of the chronic wounds.
