Platelet Rich Plasma Combined With Human Umbilical Cord Mesenchymal Stem Cells for Stage 3 and 4 Stress Injury

The 2019 edition of the International Guidelines for Clinical Prevention and Treatment of Stress Injury states that stress injury, as a globally prevalent health issue, significantly reduces the quality of life for patients and their families, increases economic burden, and leads to significant expenditure on medical resources. In recent years, the incidence and mortality rate of pressure injuries in hospitalized patients have been increasing year by year. Therefore, there is an urgent need to find a more effective treatment method for pressure injuries in clinical practice. Human umbilical cord mesenchymal stem cells (huMSCs) have immunomodulatory and anti-inflammatory effects. Platelet rich plasma (PRP) can also secrete various nutritional factors, which can effectively promote wound healing. Therefore, the combination of the two may be a more effective treatment method for pressure injuries. At present, there are few reports on the combination of PRP and huMSCs for the treatment of pressure injury. In this study, the investigators aim to evaluate the effectiveness and safety of PRP combined with huMSCs for stage 3 and 4 pressure injuries, In order to promote their clinical application.
