Background.Recently, intra-articular tranexamic acid (IA-TXA) application has become a popular method for perioperative blood loss (PBL) reduction in total knee replacement (TKR). Nevertheless, through our knowledge, no previous studies had shown the correlation perioperative factors and the risk of excessive PBL or need of blood transfusion (BT) after IA-TXA.Materials and Methods.A retrospective study was conducted in patients underwent 299 primary TKRs, using IA-TXA, during 2-year period (2013-2014). Patient’s characteristic and perioperative data were reviewed and collected. PBL was measured as total hemoglobin loss (THL), estimated total blood loss (ETBL), and drainage volume per kg (DV/kg). Excessive PBL was defined as PBL that exceeded 90th percentile.Results. From multivariate analysis, low preoperative hemoglobin (Hb) level and body mass index (BMI) were the significant predictors of postoperative BT (p<0.0001and 0.003, resp.). Excessive THL significant associated with preoperative Hb (p<0.0001). Excessive ETBL significantly associated with preoperative Hb, height, preoperative range-of-motion, and creatinine clearance (p<0.05all). Low BMI and large prosthesis size were the significant predictors of excessive DV/kg (p=0.0001and 0.002, resp.).Conclusions. Low preoperative Hb and BMI were the significant risks of postoperative transfusion after TKR with IA-TXA. Moreover, multiple perioperative factors could result in higher PBL.

<p class="abstract"><strong>Background:</strong> Several techniques are available to minimize the likelihood of blood transfusion following total knee arthroplasty. Tranexamic acid, an inhibitor of fibrinolysis that blocks the lysine-binding site of plasminogen to fibrin has been reported to reduce intraoperative and postoperative blood loss in patients undergoing total hip and total knee arthroplasties with or without cement. The objective of this study was to assess the efficacy of antifibrinolytic treatment along with other measures like saline adrenaline infusion, no drain, no tourniquet and hypotensive anaesthesia in reducing perioperative blood loss during total knee replacement<span lang="EN-IN">.</span></p><p class="abstract"><strong>Methods:</strong> Between January 2011 to January 2016,  seventy five consecutive patients who had given written informed consent, undergoing a TKR received tranexamic acid 15 mg/kg body weight intravenous 5 minutes before the skin incision and two doses afterwards (3 and 6 hours after the first dose respectively). TKR was performed in a routine fashion without tourniquet. The saline adrenaline (1:200000) was infiltrated into the skin subcutaneous tissue and capsule before skin incision.

Introduction:  Total knee replacement (TKR) is one of the most common surgeries in orthopedic field. Up to 1/3 of the patients require blood transfusion postoperative. Allogenic transfusion has many side effects. Tranexamic acid (TXA) is a synthetic antifibrinolytic agent. We explore the usage of TXA in reducing blood loss and transfusion rate by injecting it into the knee joint during surgery.  Materials and method: This is a retrospective study done in Hospital Tengku Ampuan Rahimah, Klang. Medical records of patient undergoing TKR between 1 January 2018 till 31 December 2018 were reviewed. Study sample was calculated as 90 patients and divided into 2 groups, one receiving TXA (study) and the other not receiving TXA (control). Post-operative hemoglobin levels and transfusion rate was recorded.  Results: 45 patients in study group (17 male, 28 female) had a mean age of 65.4 years old and 45 patients in control group (24 male, 21 female) had a mean age of 64.2 years old. Mean post-operative hemoglobin drop in study group was 1.08 g/dL vs 1.86 g/dL in control group. Repeated measure ANOVA determined a p value of 0.001 which shows a significant correlation. Total transfusion rate in study group was 1 vs 9 in the control group. Using chi-square test, the p-value was 0.007 which again shows a statistically significant result.  Conclusion: Intra-articular injection of TXA following TKR reduces blood loss and the need for blood transfusion without increasing any complication. This prevents many patients from undergoing a potentially hazardous blood transfusion. A routine usage of intra-articular TXA in patients undergoing TKR is recommended. However a large and well designed RCT is required to investigate the risk and benefits of TXA.

Results of comparative study of intra- and postoperative blood loss, rate of thromboembolic complications at total knee replacement with and without tourniquet application on the background of anticoagulant therapy with Pradaxa. It was shown that application of pneumatic tourniquet considerably decreased blood loss during the most laborious steps of operation but did not decreased the total blood loss and simultaneously increased the risk of thromboembolic complications development in the early postoperative period. Anticoagulant therapy including oral Pradaxa 220mg/day provided the convenience for the patient to continue thromboprophylaxis after discharge that greatly increased its efficacy.

Background. Recently, combined intra-articular tranexamic acid (IA-TXA) injection with clamping drain method showed efficacy for blood loss and transfusion reduction in total knee replacement (TKR). However, until now, none of previous studies revealed the effect of this technique on pharmacokinetics, coagulation, and fibrinolysis.Materials and Methods. An experimental study was conducted, during 2011-2012, in 30 patients undergoing unilateral TKR. Patients received IA-TXA application and then were allocated into six groups regarding clamping drain duration (2-, 4-, 6-, 8-, 10-, and 12-hours). Blood and drainage fluid were collected to measure tranexamic acid (TXA) level and related coagulation and fibrinolytic markers. Postoperative complication was followed for one year.Results. There was no significant difference of serum TXA level at 2 hour and 24 hour among groups(p<0.05). Serum TXA level at time of clamp release was significantly different among groups with the highest level at 2 hour(p<0.0001). There was no significant difference of TXA level in drainage fluid, postoperative blood loss, blood transfusion, and postoperative complications(p<0.05).  Conclusions. Low-dose IA-TXA application in TKR with prolonged clamping drain method is a safe and effective blood conservative technique with only minimal systemic absorption and without significant increase in systemic absorption over time.

Abstract Background There are various techniques to reduce blood loss in total knee arthroplasty (TKA), including the use of a tourniquet and tranexamic acid (TXA). In this study, we studied the combined effect of TXA with a tourniquet on blood loss in the setting of primary TKA. Methods Randomized controlled trials (RCTs) of nine treatment methods were included (placebo, intravenous [i.v.] TXA, topical TXA, i.v.-combined topical TXA, oral TXA, placebo + tourniquet, i.v. TXA +tourniquet, topical TXA + tourniquet, and i.v.-combined topical TXA + tourniquet). The patients were divided into eight groups according to the different treatment strategies, with 30 cases per group. The differences in the total blood volume, the number of patients transfused, the hemoglobin before and after the operation, and complications after the operation were compared. Results Totally 15 RCTs meeting our inclusion criteria were collected in this study. Compared with the placebo + tourniquet group, the i.v. TXA + tourniquet group displayed lower hemoglobin reduction value, pulmonary embolism (PE) incidence, total blood loss, and blood transfusion risk; the topical TXA + tourniquet group showed reduced PE incidence, total blood loss, and blood transfusion risk, and the i.v.-combined topical TXA and i.v.-combined topical TXA + tourniquet groups showed decreased total blood loss and lower blood transfusion risk. Retrospective clinical study results also demonstrated that the efficacy of i.v.-combined topical TXA was the best. Conclusions Our meta-analysis indicates that i.v.-combined topical TXA provides a low total blood loss without increasing the blood transfusion risk in patients undergoing total knee replacement surgery.
