[Abstract]:Background:1. After the total knee replacement, the bleeding aggravated the swelling of the knee joint and the increase of the patient's blood transfusion, which affected the early functional exercise of the knee joint and reduced the patient's satisfaction, and combined with the various blood transfusion complications and the background of the blood source tension of the allogenic blood, How to reduce blood loss after knee replacement and to promote that rapid rehabilitation of the knee joint has cause the high attention of the orthopaedic surgeon. It is shown that the local application of epinephrine in the artificial knee replacement can effectively reduce the postoperative blood loss, post-operative drainage, and reduce the post-operative blood transfusion rate. The aminomethylcycloacid plays a role in reducing the blood loss of the artificial knee replacement by reducing the dissolution of the fibrin, and the epinephrine topical application can contract the blood vessel, and simultaneously activate the 2-2 receptor on the platelet to play a hemostatic effect, and the two mechanisms are different, However, there is a synergistic effect in reducing blood loss. In the total knee arthroplasty, the value and safety of its application are discussed by the combination of the two. Objective: To study the effect of epinephrine EPI on total knot total knee arthroplasty (TKA) blood loss and early function recovery of total knee arthroplasty (TKA) by a randomized, controlled study. Methods:122 patients who were treated with unilateral TKA in the first Affiliated Hospital of Kunming Medical University from February 2015 to December 2016 were selected as the subject of the study and divided into four groups according to the different methods of administration. TXA + EPI group (n = 31): the epinephrine group was injected into the combined joint cavity of the tranexamic acid by intravenous drip; the TXA group (n = 31): intravenous amipionate group; EPI group (n = 30): the joint cavity was injected into the epinephrine group; the control group (n = 30): the blank control group. The patients with TXA + EPI were given an intravenous injection of 50 ml (1:200000) of epinephrine in the anterior joint cavity before the end of the suture and the drainage tube was closed after injection for 2 h. The TXA group was given the intravenous drip (10 mg/ Kg) in 1 Omin before the relaxation of the tourniquet. At the same time, the drainage tube was closed for 2 h. The EPI group was injected with 50 ml of epinephrine diluent (1:200000) into the joint cavity after the end of the suture joint capsule, and the drainage tube was closed after injection for 2 h. The control group only had the drainage tube closed after operation for 2 h, and no epinephrine was injected into the urethane ring and the joint cavity. The operative time, total blood loss, postoperative drainage rate, hidden blood loss, postoperative blood transfusion rate, postoperative 24 hD-dimer level, postoperative week-week deep venous thrombosis (DVT) rate,3-5 days post-operation and the mean change value of 10 cm peripheral diameter were observed. The postoperative day 1,3, and 5 d knee motion (rang of motion ROM), the postoperative 7 d knee HSS score, follow-up for 3 months, to determine whether deep venous thrombosis occurred. Results: One patient in the TXA + EPI group had delayed healing and extended to 3 weeks. The wound of the remaining three groups was healed in the first stage and the left and right after 2 weeks, no incision and skin necrosis occurred, and no pulmonary embolism occurred. (1) The general conditions, operative time, pre-operative hemoglobin, preoperative hematocrit, pre-operative knee motion and pre-operative HSS score were not statistically significant (P0.05). No symptomatic deep vein thrombosis was noted for follow-up. (2) The total blood loss of the four groups was significantly lower than that of the control group (P0.05). The TXA + EPI group, the TXA group and the EPI group were significantly lower than those in the control group (P0.05). There was no significant difference in the total blood loss in the TXA group than in the EPI group (P0.05). However, in the postoperative drainage rate, the reduction of the group of the EPI group and the group of the TXA group was more obvious, the difference was significant (P0.05), and the TXA + EPI group and the TXA group were not significantly different (P0.05), and the TXA + EPI group and the TXA group were not significantly different (P0.05). The postoperative blood transfusion rate was reduced in the EPI group and the control group, but there was no significant difference between the three groups. There was no significant difference in the pre-operation of D-dimer in the four groups, and the D-dimer in the control group increased, but the level of TXA was higher in the control group and the EPI group. (3) The mean change value of TXA + EPI group was significantly lower than that of the control group (P0.05). There was no significant difference in the mean change of the mean change of the diameter of the group in the TXA group after 3-5 days after the operation and the mean change of the peripheral diameter of 10 cm (P0.05). (4) In the group of TXA + EPI, the first, third, and 5d knee-motion ROM in the group were significantly higher than that of the control group (P0.05). In the group of TXA and EPI, the first, third, and 5d knee-motion ROM in the group of TXA and EPI were significantly higher than those in the control group (P0.05). There was no significant difference in HSS (P0.05). Conclusion: (1) The injection of epinephrine in the combined joint cavity of the tranexamic acid can significantly reduce the blood loss after the primary unilateral TKA, and the decrease of the recessive blood loss is more obvious, and the postoperative blood transfusion rate is reduced, but the risk of deep vein thrombosis after operation is not increased; (2) The injection of the epinephrine in the combined joint cavity of the tranexamic acid in the intravenous drip obviously reduces the knee joint swelling in the early postoperative period, increases the motion of the knee joint, effectively improves the function of the knee joint in the early postoperative period, improves the rapid rehabilitation of the knee joint, and has certain application value, But it is possible to cause complications such as wound delay and the like, and the clinical application needs to be cautious.
