About this study

Official title: Comparison of Topical Versus Intravenous Tranexamic Acid in Primary Total Knee Arthroplasty:A Prospective Randomized Study

Previous studies in both the cardiovascular and orthopedic study have shown tranexamic acid (TXA) reduces blood loss and post-operative blood transfusion rate largely without major complications . In addition, many meta-analyses have confirmed these results . However, there is little information about comparison among the different routes of TXA administration in TKA. Therefore, this study has been designed to determine which administration route of TXA is more effective and safety.

Read the detailed description

Objectives:To assess the efficacy and safety between the two different applying routes.

Patients in this project will be randomly divided into three groups , one group is a blank group and the rest two receive either the topical or the intravenous form of tranexamic acid during unilateral TKA(total knee arthroplasty).The total blood loss(TBL) will be calculated as the primary outcome for efficacy while Deep Vein Thrombosis、Pulmonary Embolism、Acute Myocardial Infarction 、 Acute Kidney Infarction and Cerebral Infarction events will be recorded to assess the safety of the tranexamic acid during a six-week follow-up for each patient.

All surgery are under general anesthesia, through direct lateral approach with cementless prosthesis.For all patients, the drain tube will be clamped and closed completely for 2 hours; then the clamp will be fully opened.

Being tested
normal saline, Tranexamic Acid
Keywords

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • normal salineDrug

    Also called 0.9% sodium chloride

    The normal saline solution will be prepared under sterile conditions. In the operation room the sterile bag containing the solution will be given to the scrub nurse. The contents (60 ml) will be emptied in a sterile surgical bowl and the nurse will ask the surgeon to apply the solution before wound closure.The dosage and applying route can also be looked up in doctor's order sheet.

  • Tranexamic AcidDrug

    Also called Cyclokapron

    The Tranexamic Acid solution will be prepared under sterile conditions. In the operation room the sterile bag containing the solution will be given to the scrub nurse. The contents (60 ml) will be emptied in a sterile surgical bowl and the nurse will ask the surgeon to apply the solution before wound closure.The dosage and applying route can also be looked up in doctor's order sheet.

  • Tranexamic AcidDrug

    Also called Cyclokapron

    The Tranexamic Acid solution will be prepared under sterile conditions. In the operation room the sterile bag containing the solution will be given to the circuit nurse and the circuit nurse will ask the anesthetist to apply the solution intravenously before tourniquet deflation. The dosage and applying route can also be looked up in doctor's order sheet.

Study groups in NCT02393300
Study groupRoleWhat they receive
Group1Placebo comparator60 Milliliters(ml)Normal saline (0.9% sodium chloride) will be applied by soaking the knee cavity for at least 3 minutes before wound closure and then sucked away.
Receives: Drug: normal saline
Group2Experimentaltwo-dose intravenous tranexamic acid will be applied as follow: 10mg/kg of Tranexamic Acid in 100 Milliliters(ml) normal saline (0.9% sodium chloride),the first dose 15' before the tourniquet deflation and the second dose at 180' after the first dosage
Receives: Drug: Tranexamic Acid
Group 3Experimental3g Tranexamic Acid diluted to 60 Milliliters(ml) with normal saline (0.9% sodium chloride) will be applied by soaking the knee cavity for at least 3 minutes before wound closure and then sucked away.
Receives: Drug: Tranexamic Acid

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Total Blood Loss(TBL)

    Total Blood Loss(TBL) was calculated with equations described by Gross et al.

    Measured: calculated by an equation at the fifth postoperative day

Secondary outcomes (1)
  1. Transfusion rates

    Include The number of units of perioperative blood transfusions, both intraoperative and postoperative, over the course of the patient's hospital stay

    Measured: from the day of surgery to the day of discharge,an expected average of 7 days

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing normal saline and Tranexamic Acid in people with Total Blood Loss, run by Shanghai Jiao Tong University School of Medicine at 1 site in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 4 Apr 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Total Blood Loss(TBL) (time frame: calculated by an equation at the fifth postoperative day). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 4 Apr 2018.
