- W4287035575 abstract "Activated platelets release a rich broth of growth factors involved in wound healing. One way to deliver activated platelets to wounds is in the form of platelet-rich plasma (PRP) harvested by centrifuging the patient's venous blood after activating the platelets with collagen or calcium chloride and/or autologous thrombin, then delicately removing the supernatant, called platelet-poor plasma (PPP). Platelet-rich plasma is usually injected into the lesion and/or applied topically, then sealed in or over the wound using a moisture-retentive dressing. Platelet-rich plasma (often with PPP) has been applied at different times, depths, and frequencies to chronic and acute wounds using various PRP doses and vehicles to achieve widely differing results. Meta-analyses have reported that PRP improved healing rates of open diabetic foot ulcers and venous ulcers and may reduce pain and surgical site infection (SSI) incidence in open and closed acute surgical wounds. However, inconsistency in study methods and outcome measures limited consistency of pain and SSI results. No consistent effect on healing or deep SSI rates was reported as a result of adding 1 intraoperative dose of PRP in the surgical site before closing elective foot and ankle surgery incisions of 250 patients as compared with 250 similar patients receiving the same procedure without PRP. After decades of research, ideal parameters of PRP delivery and use on each type of wound remain unclear for improving SSI, acute wound pain, and healing outcomes. This installment of the Evidence Corner reviews 2 surgical studies that may provide clues about optimal PRP use. One triple-blind randomized clinical trial (RCT) focused on irrigation of freshly closed carpal ligament surgical incisions with PRP as compared with PPP. Another non-blind RCT explored the effect of injecting PRP into open pilonidal sinus excisions 4 days and 12 days after surgery." @default.
