تنزيل WOUND INFECTION Platelet-rich fibrin (PRF) substance is a by-product of blood (plasma) that is rich in platelets. PRF, in short, is simply a byproduct of blood. It is exceptionally high in platelets and growth factors, the “signaling” molecules that allow communication between cells. PRF is a tool that significantly improves bone and soft tissue regeneration. Recently, its use has been advocated for regenerative periodontics and wound healing.
Platelet-rich fibrin is the new thing when it comes to surgery, with improved healing and immune support. The operation can have a faster and better recovery, with fewer post-operative complications. The application of platelet-rich fibrin during the implantation process enhanced the stability of the implants. The application of platelet-rich fibrin improves the stability of the implant in the first week of osseointegration. The biggest advantage of using platelet-rich fibrin is its complete absorption, thus avoiding the time of the second surgery, which is definitely a critical factor in elderly patients. This appears to be a minimally invasive technique with low risk and satisfactory clinical outcomes such as preventing complications or implant failure especially in age-related elderly patients.
Wound infection is invasion of microorganism through tissue after breakdown of local and/ or systemic host defense, with production of local inflammatory reaction. wound infection could be at the time of injury or later on. it depends on host resistance, and virulence of the microorganism, figure 1. Thousands of bacteria live normally on every square centimeter of your skin. If the skin barrier is disrupted as a consequence of trauma, surgery or disease, these bacteria may invade and cause a symptomatic infection. Micro-organisms from the environment (e.g., soil, water) or from a mucosal surface (e.g., following a bite) may also contaminate a skin wound. The incidence of wound infection ranges from 2 to 17.5 per cent after trauma and from 1 to 1.5 per cent after minor dermatological surgical procedures. Infections are inconvenient and painful, and lead to failure or delay in wound healing and poor cosmetic outcomes.
