Background Extensive blood loss is common in pediatric craniosynostosis reconstruction surgery. Tranexamic acid (TXA) is increasingly used to reduce perioperative blood loss in various settings, but data on its efficacy are limited in children. The purpose of this randomized, double-blind, placebo-controlled, parallel trial was to evaluate the efficacy of TXA in pediatric craniosynostosis correction surgery. The primary and secondary outcome variables were reduction in perioperative blood loss and reduction in blood transfusion, respectively. Methods Forty-three children, ages 2 months to 6 yr, received either placebo or TXA in a loading dose of 50 mg·kg(-1), followed by an infusion of 5 mg·kg·h(-1) during surgery. TXA plasma concentrations were measured. Results The TXA group had significantly lower perioperative mean blood loss (65 vs. 119 ml·kg(-1), P < 0.001) and lower perioperative mean blood transfusion (33 vs. 56 ml· kg(-1), P = 0.006) compared to the placebo group. The mean difference between the TXA and placebo groups for total blood loss was 54 ml·kg(-1) (95% CI for the difference, 23-84 ml·kg(-1)) and for packed erythrocytes transfused was 23 ml·kg(-1) (95% CI for the difference, 7-39 ml·kg(-1)). TXA administration also significantly diminished (by two thirds) the perioperative exposure of patients to transfused blood (median, 1 unit vs. 3 units; P < 0.001). TXA plasma concentrations were maintained above the in vitro thresholds reported for inhibition of fibrinolysis (10 μg·ml(-1)) and plasmin-induced platelet activation (16 μg·ml(-1)) throughout the infusion. Conclusions TXA is effective in reducing perioperative blood loss and transfusion requirement in children undergoing craniosynostosis reconstruction surgery.

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.

Aims The aims of this study were to compare the efficacy and safety of intra-articular and intravenous (IV) tranexamic acid (TXA) in controlling perioperative blood loss in total knee arthroplasty (TKA) using a randomized, double-blinded equivalence trial. Patients and Methods A total of 182 patients aged between 45 and 75 years undergoing unilateral TKA at a tertiary centre were randomized to receive TXA, either 1.5 g intra-articularly after closure of the wound (n = 91) or two doses of 10 mg/kg IV (n = 91). The primary outcome measure was the reduction in the level of haemoglobin (Hb) in the blood on the fifth postoperative day. Secondary outcome measures were the total, visible, and hidden blood losses (TBL, VBL, HBL). We assumed equivalence of the primary outcome in both routes with a margin of ± 0.35gm/dl. Block randomization using computer-generated random numbers was used. The patients and the assessor of outcome were blinded. Results All patients completed the study. The mean difference in the reduction of the level of Hb between the two groups was -0.0055 gm/dl, with two-sided 95% confidence interval (CI) being -0.29 to 0.27, well within the predefined equivalence margin of ± 0.35gm/dl. The groups were comparable with regard to TBL, VBL, HBL, and complications. No patient needed a blood transfusion. Conclusion A single intra-articular dose and two IV doses of TXA give equivalent efficacy and safety in the management of blood loss at TKA. Cite this article: Bone Joint J 2018;100-B:152–60.

Objectives: Tranexamic acid (TXA) is a commonly used medication in orthopaedic procedures, reducing perioperative bleeding and need for transfusion. The purpose of this double-blind randomized controlled study was to evaluate if IV TXA for primary anterior cruciate ligament (ACL) reconstruction with bone-patella tendon-bone (BTB) could reduce perioperative blood loss or postoperative intra-articular hemarthrosis without postoperative drains. Methods: A controlled, randomized, double-blinded trial was conducted in 110 patients who underwent ACLR with BTB autograft. Patients were equally randomized to the control and experimental groups. The experimental group received two 1-gram boluses of IV TXA, one prior to tourniquet inflation and one prior to wound closure; the control group did not receive TXA. If a clinically significant hemarthrosis was evident, the knee was aspirated, and the volume of blood (ml) was recorded. Additionally, perioperative blood loss (ml); Visual Analog Scale (VAS) on postoperative days (POD) 1-7 and post-operative weeks (POW) 1, 6 and 12; postoperative opioid consumption POD 1-7; range of motion (ROM) and ability to straight leg raise (SLR) at POW 1, 6, 12; and pre and postoperative thigh circumference ratio (TCR). Results: There was no significant difference in perioperative blood loss between the experimental and control groups (32.5ml v. 35.6ml, p=0.47). The experimental group had 23 knees aspirated; control group had 26 knees aspirated (p=0.56). No significant difference seen in postoperative hemarthrosis volume with IV TXA (26.7ml v. 37.3ml, p=0.12). There was no significant difference in VAS score between the two groups (p=0.15), additionally, there was no difference in postoperative opioid consumption (p=0.33). There was no significant difference in ROM or ability to SLR, or pre- nor post-operative TCR (p > 0.05 for all). Conclusions: IV TXA in patients who undergo ACLR with BTB autograft does not significantly impact perioperative blood loss, postoperative hemarthrosis, or postoperative pain levels. Additionally, no significant differences were seen in early post-operative recovery regarding ROM or quadriceps reactivation.

Abstract Tranexamic acid (TXA) is an inexpensive, commonly used antifibrinolytic agent that has been shown to significantly reduce perioperative blood loss and transfusion requirements after total hip and knee replacement. We conducted a systematic review and meta-analysis to synthesise the latest evidence regarding the effects of TXA on blood loss in total shoulder replacement (TSR) and total elbow replacement (TER). We systematically searched MEDLINE, EMBASE and CENTRAL from inception to 03 September 2020 for randomised controlled trial (RCTs) and observational studies. Our primary outcome was blood loss, and secondary outcomes included the need for blood transfusion and venous thromboembolic (VTE) complications. Four RCTs and five retrospective cohort studies (RCS) met eligibility criteria for TSRs, but none for TERs. RCT data determined that TXA administration significantly decreased estimated total blood loss, postoperative blood loss, change in haemoglobin (Hb) and total Hb loss when compared to placebo. RCS data demonstrated significant association between TXA administration and decreased in postoperative blood loss, change in Hb, change in Hct and length of stay. This meta-analysis demonstrates that TXA administration in primary TSR significantly decreases blood loss compared with placebo and is associated with lower blood loss and shorter length of stay compared with no treatment with no increase in VTE complications. TXA administration should be part of a wider blood management strategy to minimise perioperative blood loss and blood transfusion requirements in patients undergoing TSR. Further research is needed to demonstrate if a similar treatment benefit exists in patients undergoing TER.

Abstract Background: The specific method and dose of tranexamic acid (TXA) topically applied for intertrochanteric fractures have not been well established. The aim of this study is to investigate the efficacy and safety of TXA topically administered via our protocol for perioperative bleeding management in elderly patients with intertrochanteric fractures who underwent proximal femoral nail anti-rotation (PFNA).Methods: A retrospective comparative analysis was performed. The TXA group was composed of 82 patients with topical use of TXA, and the control group was composed of 82 patients without TXA use during the PFNA procedure. Intraoperative, total and hidden amounts of blood loss, drainage volumes, postoperative blood transfusion volumes and complications were compared between the two groups.Results: The intraoperative, total and hidden amounts of blood loss and the drainage volumes were significantly lower in the TXA group than in the control group (P=0.012, P<0.01, P<0.01, P=0.014, respectively). The volume and rate of blood transfusion in the TXA group were significantly lower than those in the control group (P<0.01). There were no significant differences in complications between the two groups (P>0.05).Conclusion: Topical application of TXA offers an effective and safe option for reducing perioperative blood loss and transfusion in elderly patients with intertrochanteric fractures undergoing PFNA.

AbstractBackground: The use of a tourniquet during total knee arthroplasty (TKA) continues to be a matter of debate. Advantages of tourniquet use include improved visualization, decreased intraoperative and total blood loss, and possibly decreased transfusion requirement. However, the recent widespread adoption of antifibrinolytic therapy with tranexamic acid (TXA), may negate these benefits. The purpose of this study was to evaluate perioperative blood loss and transfusion requirement with two different tourniquet application strategies, and surgery without the use of a tourniquet during routine, primary cemented TKA.Methods: A retrospective cohort study was performed of 300 patients undergoing TKA at a single institution after the implementation of a routine intravenous TXA administration protocol and consisted of three groups based on tourniquet usage: tourniquet inflation before incision and deflation following cement hardening (TQ), tourniquet inflation prior to cement application and deflation following hardening (Partial TQ), and no tourniquet usage (No TQ). Each group consisted of 100 consecutive patients. Perioperative blood loss, change in hematocrit and transfusion requirement were compared between groups. Results: Total blood loss (estimated blood loss and drain output) was lowest in the TQ group, however this was only due a slight decrease in intraoperative estimated blood loss. There was no difference in post-operative drain output, or change in hematocrit levels from preoperative values. There were no transfusions in the Partial TQ and No TQ groups, whereas there were 5 transfusions in the TQ group.Conclusions: In the era of routine TXA administration during TKA, tourniquet usage does not appear to have a benefit in regards to perioperative blood loss or transfusion requirement.

Background: Preoperative administration of Tranexamic acid (TXA) has been found to be effective in reducing the amount of blood loss following Caesarean section in low risk women. However, studies in high risk women such as women with anaemia, where blood loss needs to be minimised are scarce.Methods: An experimental case control study was conducted with a total of 174 patients with moderate anaemia undergoing CS in a teaching hospital. Study group consisting of 87 patients received pre-operative TXA 1g intravenously. Intra operative and up to 6hours postpartum blood loss was calculated in both the groups. Requirement of blood transfusions were noted. Data analysed using Graphpad Instat® 3 statistical software.Results: Present study showed statistically significant reduction in intraoperative and postoperative blood loss among patients who received TXA compared to control group. The blood loss from placental delivery till completion of the procedure was significantly lowered (304.02ml vs 393.36ml; p value <0.0001). Postoperative blood loss (from end of the procedure up to 6hrs postpartum) was 62.57ml in comparison to 85.40ml in control group (p value <0.0001). The total blood loss from the placental delivery up to 6 hours postpartum was significantly reduced in study group (366.59ml vs 478.76ml; p value <0.0001). There was significant reduction of blood transfusion in study group (RR: 0.20, 95% CI, 0.045-0.887), without immediate adverse effect on mothers and new-borns.Conclusions: Administration of TXA preoperatively causes significant decrease in blood loss and the need for blood transfusion in patients with moderate anaemia undergoing CS.
