Background:Total knee arthroplasty (TKA) is one of the most common orthopedic surgeries in the world. The use of tourniquet is recommended by some surgeons around the world. However, the evidence of its usefulness in replacing the knee is still uncertain. In the present study, we assessed the effect of using tourniquet in reducing bleeding during and after operation and the amount of transfusion requirement in TKA surgery.Methods and Materials:Patients referred to Imam Reza and Tabriz universal hospitals for TKA surgery in case of absence of hemorrhagic diseases and non-use of anticoagulants were included in this study. In this study, 8 (25.8%) males and 23 (74.2%) females were present with an average age of 63.6 ± 7.86 with a minimum age of 52 years and a maximum age of 81 years. Patients' Randomization applied considering balanced mean age and body mass index (BMI). In the first group after the patient's preparation and induction of anesthesia, the tourniquet was considered and surgery was performed and the tourniquet was released immediately after the cement was inserted. In the second group after the patient's preparation and induction of anesthesia, tourniquet was not used until cementation and after that again deflated. All surgical procedures were performed by the same and experienced surgical team using spinal epidural anesthesia. The standard surgical procedure was considered by surgeons.Results:23 (74.2%) patients did not need blood transfusion, and 8 (25.8%) patients needed transfusion. The average duration of surgery was 75.81 ± 26.3 minutes with a minimum duration of 30 minutes and a maximum of 125 minutes. The mean preoperative HB level was 12.66 ± 1.67, which was 11.09 ± 1.62 after surgery.Conclusion:In conclusion, the use of tourniquet in patients undergoing TKA surgery reduces the duration of surgery but does not significantly affect hemoglobin maintenance after surgery. In other words, the use of tourniquet does not have an effect on reducing the need for blood transfusion.
