Objective To observe the effects of platelet-rich plasma (PRP) gel in the treatment of [Ⅳ stage pressure ulcers.Methods A total of 12 patients with stage Ⅳ pressure ulcers were treated with PRP gel from December 2012 to December 2013 in our department.The PRP gel was formed by autologous PRP mixed with thrombin and calcium chloride.The PRP gel was applied to the wound after dressing.Time intervals between dressing were 4 days.Overall pressure ulcer improvement was assessed every week until complete wound healing.Results All stage Ⅳ pressure ulcer wound infection was controlled and fresh granulation tissue was found after 2 times of PRP gel covering.The time of ulcer wound healing were 6-10 weeks (mean 8 weeks).The times of changing the PRP gel were 16.No patients experienced adverse reactions during treatment.Conclusions PRP gel can effectively control the pressure ulcer infection and promote ulcer wound healing.

Retrospective analysis was performed for the clinical data of 15 chronic insertion achilles tendinitis patients undergoing platelet-rich plasma (PRP) trigger point injection.The scores of Validated Victorian Institute of Sports Assessment-Achilles (VAS-A) and foot function index (FFI) improved greatly versus pre-treatment (all P < 0.05).Tendon insertion structure inflammation decreased significantly on magnetic resonance imaging.At the last follow-up,all patients recovered normal gait and daily activity.The trigger point injection of PRP is efficacious for chronic insertion achilles tendinopathy.
