Completed

Target enrollment:

Participant gender:
All
Summary
Objectives: a) Principal: To assess if the fibrin glue or the tranexamic acid reduce less than 20% the blood losses with respect to the habitual haemostasia in patients with arthroplasty total of knee. Secondaries: To assess the treatment safety. To perform a cost- analyses. Methods: Randomized, unicentric, and parallel clinical trial with four comparative groups: Tissucol® (fibrin glue), fibrin glue manufactured by the Cryoseal® system (Banc de Sang i Teixits de Catalunya), tranexamic acid and habitual haemostasia. Nº of participant centres: 1. Random allocation will be centralised. Main outcome: Blood losses (ml) in the post-operatory period collected by the habitual drain system. Secondary outcomes: Proportion of patients with blood transfusion, complications of surgery wound, pre and post-operative haemoglobin, units of blood transfused, post-operative mortality, days of hospital stay, safety of interventions assessed. Size sample calculation: The number needed of patients is 172 (43 per group) to demonstrate a 20% difference in the post-operative blood losses between the treatments assessed and the habitual haemostasia, with a statistical power of 80% and a 0.05 bilateral alpha, and a 20% of withdrawals. Statistical analysis: The investigators will perform a comparison of outcomes through the "t" test, the Mann-Whitney test of chi square, depending of the evaluated outcomes, quantitative or ordinals or qualitative, respectively. The software used will be Statistical Package for the Social Sciences (SPSS) version 17.
