Effect of Suction Drains in Total Knee Arthroplasty With Tranexamic Acid

(L'Effet Des Drains Aspiratifs en Arthroplastie du Genou Avec l'Utilisation de l'Acide Tranexamique)

Problem Suction drains during TKA present certain costs to the health system and requires additional nursing care. There is no clear evidence that supports their use, and no studies so far have compared blood loss in patients with or without drains when TA is administered during TKA.

Hypothesis During total knee arthroplasty, the postoperative blood loss, measured by hemoglobin level, will be lower when no drains are used.

Method

• Randomized controlled trial
• Monocentric, 3 surgeons
• Randomisation by sealed envelopes

During total knee arthroplasty, the postoperative blood loss, measured by hemoglobin level, will be lower when no drains are used.

Inclusion Criteria:

• Unilateral primary total knee arthroplasty

Exclusion Criteria:

• TKA revision
• Bilateral TKA
• Patients that refuse transfusions
• Contraindication to tranexamic acid use: allergy, thromboembolic history
• Coagulopathy
• Kidney failure
