The Effect of PRP on Wound Healing in High Risk Patients Undergoing Abdominal Hysterectomy

on the morning of surgery, 30 mL of venous blood will be drawn from the patient in anticoagulant-containing PRP tube for preparation of PRP solution. The drawn blood will be centrifuged at 1,200 rpm for 12 minutes to be separated into three layers: an upper layer that contains platelets and white blood cells, an intermediate thin layer (the buffy coat) that is rich in white blood cells, and a bottom layer that contains red blood cells. The upper and intermediate buffy layers will be transferred to an empty sterile tube. The plasma will be centrifuged again at 3,300 rpm for 7 minutes to help with the formation of soft pellets (erythrocytes and platelets) at the bottom of the tube. Pellets are homogenized in the lower third (5 mL) of the plasma to create the PRP. The prepared PRP solution will be transferred within sterile single use syringe (3cm) from the laboratory to the operation room, then applied and spread over the subcutaneous space before skin closure
