Liu CH, Chang CH, Chang YH, Shih HN, Hu CC. Topical Fibrin Sealant (Tisseel@) Does Not Provide a Synergic Blood-Conservation Effect with Tranexamic Acid in Total Knee Arthroplasty-A Prospective Randomized Controlled Trial. MEDICINA (KAUNAS, LITHUANIA) 2023; 59:2078. [PMID: 38138181 PMCID: PMC10744547 DOI: 10.3390/medicina59122078] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/04/2023] [Revised: 11/20/2023] [Accepted: 11/23/2023] [Indexed: 12/24/2023]
Abstract
Background and Objectives: The efficacy of tranexamic acid (TXA) in reducing perioperative blood loss during total knee arthroplasty (TKA) is well established. However, the potential synergistic blood-conservation effect of topical fibrin sealant (Tisseel@) remains unclear. This study aims to assess the effectiveness of the combination of Tisseel and TXA during TKA. Materials and Methods: A single-blinded, prospective, randomized controlled trial was conducted with 100 patients (100 knees) undergoing primary TKA. Participants were randomly assigned to either the TXA group (n = 50), receiving intravenous (IV) TXA, or the Tisseel@ + TXA group (n = 50), receiving intra-articular Tisseel@ combined with IV TXA. The primary outcomes included blood transfusion rate, decrease in Hb level, calculated blood loss, and estimated total postoperative blood loss. Secondary outcomes involved assessing clinical differences between the groups. Results: The transfusion rate was zero in both groups. The average estimated blood loss in the Tisseel@ + TXA group was 0.463 ± 0.2422 L, which was similar to that of the TXA group at 0.455 ± 0.2522 L. The total calculated blood loss in the Tisseel@ + TXA group was 0.259 ± 0.1 L, compared with the TXA group's 0.268 ± 0.108 L. The mean hemoglobin reduction in the first 24 h postoperatively was 1.57 ± 0.83 g/dL for the Tisseel@ + TXA group and 1.46 ± 0.82 g/dL for the TXA-only group. The reduction in blood loss in the topical Tisseel@ + TXA group was not significantly different from that achieved in the TXA-only group. The clinical results of TKA up to the 6-week follow-up were comparable between the groups. Conclusions: The combination of the topical fibrin sealant Tisseel@ and perioperative IV TXA administration, following the described protocol, demonstrated no significant synergistic blood-conservation effect in patients undergoing TKR.

Topical co-delivery of platelet rich fibrin and tranexamic acid does not decrease blood loss in primary total knee arthroplasty compared to the standard of care: a prospective, randomized, controlled trial. Knee Surg Sports Traumatol Arthrosc 2021; 29:519-528. [PMID: 32170355 DOI: 10.1007/s00167-020-05938-1] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/14/2019] [Accepted: 03/03/2020] [Indexed: 11/27/2022]
Abstract
PURPOSE The purpose of this study was to evaluate the efficacy of intra-operative co-administration of tranexamic acid (TA) and platelet rich fibrin (PRF) using a proprietary co-delivery system on the amount of blood loss, early functional outcomes and wound complications after primary total knee arthroplasty (TKA). The intervention was compared to the standard of care (combined intravenous & topical TA) in a prospective, randomized, blinded setting. METHODS 80 patients undergoing primary cemented TKA without tourniquet were prospectively randomized into control (combined intravenous and topical TA) and PRF (intra-venous TA and co-delivery of topical PRF and TA) groups after informed consent. Total blood loss, drainage blood loss, knee range of motion, VAS pain scores, length of stay and wound complications were analysed. Data collection was performed in a double blind manner on days 1, 3 and 21. RESULTS There was no statistically significant difference in drainage blood loss (550 ml vs. 525 ml, p = 0.643), calculated total blood loss on day 1 (401 ml vs. 407 ml, p = 0.722), day 3 (467 ml vs 471 ml, p = 0.471) and day 21 (265 ml vs. 219 ml, p = 0.082) between the PRF and control groups respectively. The PRF group had a small but statistically significant increase in median knee extension in the early post-operative period, however this difference evened out at 3 weeks. No significant difference could be demonstrated between the PRF and control groups in length of stay, VAS pain scores, narcotic usage, wound complications and knee flexion at all time points. CONCLUSIONS The topical co-delivery of PRF and TA does not significantly decrease blood loss in primary TKA compared to the standard of care. Slightly better active knee extension in the first 3 postoperative days can be achieved, however this benefit is not clinically relevant. LEVEL OF EVIDENCE I, Therapeutic study.

Abstract
BACKGROUND Complications including staple-line leakage and bleeding may occur after sleeve gastrectomy and Roux-en-Y gastric bypass. In this meta-analysis, the efficacy of fibrin sealant in strengthening the staple line and reducing complication risk after bariatric surgery was evaluated. METHODS We searched PubMed, Embase, and Cochrane Library databases for randomized controlled trials (RCTs) published up to October 2020. Pooled estimates of the outcomes were computed using a random effects model. The primary outcomes were bleeding and leakage; secondary outcomes were gastric stricture, length of hospital stay, reoperation rate, and total operation time. RESULTS In total, 9 RCTs including 2136 patients were reviewed. Our meta-analysis revealed that compared with controls, fibrin sealants decreased incidence of bleeding significantly (risk ratio [RR] = 0.42; 95% confidence interval [CI], 0.18-0.97), but did not demonstrate significant differences in reducing the incidence of leakage (RR = 0.62; 95% CI, 0.23-1.73), gastric stricture (RR = 1.16; 95% CI, 0.46-2.91), reoperation rate (RR = 0.85; CI, 0.14-5.14), or length of hospital stay (weighted mean difference = 0.62; 95% CI, - 0.31 to 1.55). Compared with oversewing, fibrin sealant use reduced the operation time; however, their efficacies in reducing the incidence of postoperative bleeding and leakage did not differ significantly. CONCLUSIONS Although applying fibrin sealants to the staple line in bariatric surgery may provide favorable results, but it may not reduce postoperative leakage and stricture incidence significantly. Nevertheless, the application of fibrin sealants as a method for reducing risks of complications after bariatric surgery warrant further investigation.

Rev Bras Ortop 2019; 54:322-328. [PMID: 31363288 PMCID: PMC6597421 DOI: 10.1055/s-0039-1692447] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/27/2018] [Accepted: 07/10/2018] [Indexed: 11/18/2022] Open
Abstract
Objective
The present study aimed to evaluate the results of the intraoperative topical use of a human fibrin sealant free of clot-stabilizing agents in total knee arthroplasties (TKAs), looking for differences between groups regarding blood loss, transfusion requirement, length of hospital stay, pain perception, range of motion (ROM), and incidence of complications.
Methods
We have analyzed prospectively an intervention group with 32 patients (Sealant) and a control group with 31 patients (Control) with symptomatic knee osteoarthritis who underwent TKA.
Results
The results were similar between the groups regarding visible blood loss in the drain in 24 hours (Control, 276.5 mL ± 46.24 versus Sealant, 365.9 mL ± 45.73), total blood loss in 24 hours (Control, 930 mL ± 78 versus Sealant, 890 mL ± 67) and in 60 hours after surgery (Control, 1,250 mL ± 120 versus Sealant, 1,190 mL ± 96), blood transfusion requirement (which occurred only in 1 control patient), length of hospital days stay (Control, 5.61 ± 0.50 versus Sealant, 4.81 ± 0.36), postoperative pain, and ROM. Sealant use was not related to wound healing complications, to infection, or to deep venous thrombosis.
Conclusion
We have concluded that the hemostatic agent composed of human fibrin was not effective in reducing bleeding volume and blood transfusion requirement, nor it interfered with hospital length of stay, pain perception, and ROM. Its use was not related to any complications.

Abstract
BACKGROUND The efficacy of tranexamic acid (TXA) plus drain-clamping in reducing blood loss after total knee arthroplasty (TKA) is controversial. This meta-analysis aimed to identify whether combined tranexamic acid and drain-clamping was superior to TXA alone, drain clamping alone and control treatments. METHODS We searched the PubMed, EMBASE, Web of Science and Google databases and the Cochrane Database of Systematic Reviews. Patients prepared for primary TKA and who underwent TXA plus drain-clamping for blood loss were included in this meta-analysis. Outcomes included the need for transfusion, total blood loss, blood loss in drainage, a decrease in hemoglobin and the occurrence of deep venous thrombosis (DVT). Stata 12.0 was used for meta-analysis. RESULTS Finally, 7 clinical studies with 839 patients were included in this meta-analysis. Compared with the control group, TXA group and drain clamping group treatments, TXA plus drain-clamping could reduce the need for transfusion, total blood loss, blood loss in drainage and the decrease in hemoglobin with statistically significance. CONCLUSIONS TXA plus drain-clamping is an efficient method for controlling blood loss after TKA, and more studies should focus on the optimal clamping duration.

A new topical hemostatic agent TT-173 reduces blood loss in a sheep model of total knee arthroplasty. Knee 2017; 24:1454-1461. [PMID: 28865948 DOI: 10.1016/j.knee.2017.08.055] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/01/2017] [Revised: 08/02/2017] [Accepted: 08/22/2017] [Indexed: 02/02/2023]
Abstract
BACKGROUND Total knee arthroplasty is associated with blood loss during the intervention and may require allogenic blood transfusion. Treatments such as tranexamic acid and fibrin sealants improved the bleeding control in several clinical trials, but the hemorrhage associated with the intervention is still significant. Thus far, very few studies have evaluated hemostatic treatments in animal models of total knee arthroplasty. This work describes a sheep model of bleeding associated with total knee arthroplasty and investigates a new class of hemostatic treatment based on recombinant tissue factor. METHODS Sheep were treated with the anticoagulant heparin, and the joint was accessed by a paramedial incision. Ligaments and menisci were eliminated and femoral condyles and tibia plateau were sectioned exposing the trabecular bone. An intra-articular drain was used to recover and quantify the blood loss during the 90-min period after treatment. The efficacy of one milligram and three milligrams of TT-173 was evaluated and compared with tranexamic acid. The occurrence of analytical alterations and systemic absorption was also investigated. RESULTS Treatment with TT-173 reduced the blood loss in comparison with control or tranexamic acid. No significant differences were observed between the two doses evaluated. Moreover, a dose of six milligrams of TT-173 did not induce any clinical or analytical alteration, and significant systemic absorption was not observed. CONCLUSION Data obtained strongly suggest that TT-173 could be useful in reducing the blood loss associated with total knee arthroplasty and without safety concerns derived from the systemic absorption of the product.

Abstract
BACKGROUND Several hemostatic treatments intended to reduce the bleeding associated to total knee arthroplasty have been investigated with varying degrees of success. TT-173 is a new topical agent based on recombinant tissue factor that activates the extrinsic pathway of coagulation. This trial aim is to evaluate the efficacy and safety of TT-173 in total knee arthroplasty. METHODS/DESIGN This is a phase II/III, sequential, simple blind, randomized, multicenter, placebo controlled and parallel clinical trial that will recruit 189 evaluable patients. Those randomized to treatment group will receive 2mg of TT-173 over the surgical surfaces of the knee. Control patients will receive physiologic saline. The follow up will consist in 6 visits during a period of 35 (±7) days. Primary endpoints will be the total blood loss and the incidence and severity of adverse events. Secondary and exploratory endpoints will include drainage production, decrease in hemoglobin level, transfusion ratio, analytical alterations, pain intensity, motion range, immunogenicity of TT-173 and the occurrence of systemic absorption. At the end of phase II, results will be evaluated by an independent committee that will recommend the continuation or the discontinuation of the trial. DISCUSSION The design proposed maximizes the safety of the participants, avoids the risk of bias derived from the limitations of masking and enable the eventual discontinuation of the trial if this is recommended by the Interim Analysis Committee. If TT-173 proves its efficacy and safety in this indication, it would become a useful tool to improve the bleeding control in total knee arthroplasty.

Abstract
Background: The alterations of the fibrinolytic components in osteoarthritic joint disease and their postsurgical modulation are not clearly understood. Preexisting hemostatic dysfunction may lead to both thrombotic and bleeding events in these patients. Aim: To profile fibrinolytic parameters in patients undergoing total joint arthroplasty prior to and on postoperative day 1. Methods: A total of 98 total joint arthroplasty patients were included in this study. Blood samples were drawn preoperatively and on postoperative day 1 status posttotal knee or total hip arthroplasty surgery. d-Dimer, plasminogen activator inhibitor 1 (PAI-1), and tissue plasminogen activator (tPA) were measured using commercially available enzyme-linked immunosorbent assay kits. Antiplasmin activity was measured by using a functional method. Results: Preoperative PAI-1, d-dimer, and tPA levels were significantly higher in arthroplasty patients compared to healthy controls. Preoperative antiplasmin level was lower than controls. Postoperative levels of PAI-1 and d-dimer were increased compared to preoperative values. Postoperative antiplasmin values were lower than preoperative levels. Changes in tPA was not significant. There was no correlation between preoperative PAI-1 and d-dimer levels. Pre- and postoperative percentage changes in each individual were calculated for PAI-1, d-dimer, tPA, and antiplasmin. There was a positive correlation between d-dimer and PAI-1. Negative correlations between antiplasmin and d-dimer and between antiplasmin and PAI-1 were noted. Conclusion: These results confirm the perturbation in the fibrinolytic system of patients undergoing total joint arthroplasty surgery. Surgical intervention may also enhance the observed changes. The alterations in the fibrinolytic system may lead to the observed hemostatic complications such as bleeding, hematoma formation, or potential need for blood transfusion.
