Purpose: The primary aim was to compare the effects of different tourniquet application methods during the TKA surgery of patients with hypertension and determine the best technique of using a tourniquet.Methods: A total of 100 patients were divided into three groups. Patients in group A who underwent TKA with tourniquet using before skin incision, and released after the skin was closed, and patients in group B with tourniquet using before the knee prosthesis was placed, and leased after the skin was closed. Patients in group C with tourniquet use before placing knee prosthesis, the tourniquet was leased after bone cement solidified. The following medical outcomes of the three groups were monitored and recorded: the operation time, intraoperative blood loss volume, postoperative complication, the amount of hidden blood loss, total blood loss, blood transfusion, swelling rate, visual analogue scale (VAS) and the knee society score (KSS).Results: The intraoperative blood loss in Group A was significantly low than that in Group B and Group C(P 0.05). Conclusion: Tourniquets could be used before placing the cement knee prosthesis, and loosened after the suture is completed and the pressure bandage is applied, which can obviously improve the intraoperative blood loss and the short-term postoperative functional effect of the patient, with fewer postoperative complications, but the long-term clinical effect needs further observation. |
