Osakidetza protocol
PRP treatment of vascular ulcers one a week PRP: a volume of 9-30 ml of blood will be collected from the patient (depending of the size of their ulcer) in sterile 4.5-ml tubes containing 3.8% sodium citrate, which will bind to the calcium ions, preventing clot formation we will add 50 μl of CaCl2 per ml liquid plasma. The extraction of the PRP fraction by sticking with a syringe and the adding of CaCl2 should be performed under sterile conditions.
Patients in the control group will be treated following the recommendations of the Ezkerraldea-Enkarterri Health Region, that is, using a moist healing environment (as described in "Uso racional de los productos de cura en ambiente húmedo. Plan de formación continuada de Osakidetza", 2011). The type of material used to treat and dress the wound will be chosen after the assessment of the wound and surrounding skin, type and quantity of exudate and whether there are signs of infection. Wound care will be carried out every 48-72 hours, as is the current usual practice.
