Retrospective study to evaluate if FIBTEM predicts the amount of postoperative bleeding in total knee replacement patients.

Full description

This retrospective study evaluate patients who underwent total knee replacement arthroplasty. Laboratory coagulation parameters, including FIBTEM, before anesthesia induction and after admission to the post-anesthetic care unit and decrement of postoperative haemoglobin and amount of transfusion were reviewed.

A correlation coefficient of ρ = 0.4 was calculated from a pilot study. We need at least 44 subjects with an α value of 0.05 and a power of 0.8.

Enrollment: 54 patients

Sex: All

Ages: 19 to 99 years old

Volunteers: No Healthy Volunteers
