Study summary

Total knee arthroplasty is often associated with excessive postoperative bleeding due to increased fibrinolysis. Hence, the objective of the proposed of this multicentre study is to determine the peri-operative bleeding comparing the application of topical and intravenous tranexamic acid with the habitual surgical haemostasis.

Read the detailed description

Objectives:

  1. Principal: To assess if the topical and intravenous tranexamic acid reduce less or at least than 20% the blood losses with respect to the habitual haemostasia in patients, after unilateral total knee arthroplasty.
  2. Secondary: To assess the treatment safety. To perform a cost- analyses.

Methods: Randomized, multicentre, open and parallel clinical trial with three comparative groups: Topical tranexamic acid, Intravenous tranexamic acid and habitual haemostasia. In all patients, a single drainage of 8mm will be inserted in the joint, and it will remain closed during one hour after the closure of the skin.

Nº of participant centres: 2. Random allocation will be centralised in "Hospital de la Santa Creu i Sant Pau".

Main outcome: Total blood loss (mL) in the post-operative period collected by the habitual drain system ).

Secondary outcomes: Total blood loss (mL)and hidden blood calculated by Nadler's formula. Proportion of patients with blood transfusion, complications of surgery wound, haemoglobin pre and post-operative, units of blood transfused, post-operative mortality, days of hospital stay, safety of interventions assessed.Direct cost analysis.

Substudy: Pharmacokinetic study. The first 24 patients included in "Hospital de la Santa Creu i Sant Pau" for tranexamic acid (12 topical- 12 intravenous) to determine:

  1. Plasmatic concentrations of tranexamic acid
  2. In topical and intravenous tranexamic acid administration determine the absorption rate and drug bioavailability by these routes: maximum plasma concentration, time to reach Cmax, AUC, and half-life.

What researchers measure

Primary outcomes

  1. Total blood loss (mL)

    Blood will be collected by drainages during the first 24 hours after surgery.

    Time frame: at 24 hours postoperatively

Secondary outcomes

  1. Hidden blood loss

    Hidden blood loss will be calculated by Nadler's formula

    Time frame: From admission to hospital until an average of 5 days postoperative period

  2. Wound complications

    We will quantify infections, haematomas and other complications related with surgery

    Time frame: 5 weeks postoperatively

  3. Adverse effect related with the interventions

    Any adverse effects related with tranexamic acid will be collected

    Time frame: 5 weeks postoperatively
