Abstract:
Objective:To evaluate the value of autologous platelet-rich plasma (aPRP) separation-retransfusion for blood conservation in the patients undergoing thoracolumbar laminectomy.Methods:Sixty American Society of Anesthesiologists Physical Status classification Ⅰ or Ⅱ patients, aged 18-60 yr, with body mass index of 19-30 kg/m 2, scheduled for elective thoracolumbar laminectomy, were divided into 2 groups ( n=30 each) using a random number table method: conventional blood conservation group (group C) and aPRP blood conservation group (group aPRP). Group C received tranexamic acid and autologous blood salvage-retransfusion. Group aPRP received aPRP separation-retransfusion, tranexamic acid and autologous blood salvage-retransfusion. The volume of allogeneic blood transfused, percentage of patients who did not need the allogeneic blood transfusion and adverse reactions were recorded. Venous blood samples were collected for blood routine examination and for determination of the plasma concentrations of interleukin-6 (IL-6) and IL-10 at 1 day before operation (T 0), when the volume of blood loss reached 500 ml (T 1), immediately after surgery (T 2), and at 24 and 48 h after surgery (T 3, 4). The incidence of hypoxemia and amount of 24-h wound drainage were recorded. Results:Compared with group C, the amount of allogeneic red blood cells, plasma transfused and 24-h wound drainage were significantly decreased ( P<0.05), the percentage of patients who did not need the allogeneic red blood cell and plasma transfusion was increased (30% vs 47%, 10% vs 60%, P<0.05), the plasma concentrations of IL-6 and IL-10 at T 2-4 were significantly decreased ( P<0.05), and the incidence of hypoxemia in PACU was decreased in group aPRP (27% vs 10%, P<0.05). Conclusions:aPRP separation-retransfusion can provide marked improvement in conventional blood conservation in the patients undergoing thoracolumbar laminectomy.
