- Abstract
BACKGROUND: Clinical application of autologous platelet-rich plasma is limited by the condition of patients and by the quantity and activity of platelets. Transfusable platelet component blood platelet concentrates, collected and prepared by blood collection and supply agencies, are widely available, can be standardized and are effective in the clinic. OBJECTIVE: To review the factors influencing the preparation of platelet concentrate by the buffy-coat method for the treatment of chronic refractory wounds. METHODS: A computer search of the PubMed, CNKI, and WanFang databases for platelet-related articles from January 2000 to April 2023 was conducted using the Chinese and English search terms “allogeneic platelets(concentrate), buffy-coat method, skin ulcer, refractory wounds”. The titles and abstracts were screened, and the full text was reviewed, resulting in the inclusion of 51 articles that met the subject criteria. RESULTS AND CONCLUSION: (1) Platelet concentrates supplied by blood collection and supply agencies are effective in the treatment of diabetic foot wounds, pressure sores, lower limb venous ulcers and other chronic refractory wounds: reducing the size of the ulcer and shortening the wound healing time, especially in the first two weeks, with significant healing-promoting effects. (2) The storage conditions of the raw material used to prepare platelet concentrates (whole blood overnight/buffy-coat overnight, shaking/resting (time)), centrifugation conditions (centrifugation parameters, canning method) and the structure of the blood bag can affect the concentration of platelet concentrates, indirectly affecting the efficacy of allogeneic platelet concentrates. (3) There are also some problems with studies of allogeneic platelet concentrates for the treatment of chronic refractory wounds, such as the sample size of the available evidence is small, the results lack the optimal preparation parameters, optimal dose and treatment regimen for platelet concentrates to promote healing of different wounds are unknown, so more randomized multicenter clinical studies are needed.
