Outcome Measures

Primary Outcomes (3)

  • Total blood loss (TBL)

    Total blood loss 72 hours after surgery,The Gross and Nadler formula was used to calculate TBL. TBL = patient's blood volume (PBV) x (Hctpre - Hctpost)/Hctave (Hctpre = the initial pre-operative Hct level, Hctpost = the Hct on the morning of POD3). PBV = k1 x height (m) + k2 x weight (kg) + k3 (k1 = 0.3669, k2 = 0.03219, and k3 = 0.6041 for men; and k1 = 0.3561, k2 = 0.03308, and k3 = 0.1833 for women, Hctave = the average of the Hctpre and Hctpost)

    The third day postoperative,at the time of obtaining the result of the hematocrit of 72 hours.

  • External blood loss (EBL)

    External blood loss (EBL) was estimated by adding the intraoperative bleeding and the blood in the drain collectors upon removal after 48 hours

    On the second postoperative day (48 hours), when removing the surgical drainage.

  • Hidden blood loss (HBL)

    was defined as Total blood loss minus External blood loss

    The third day postoperative

Secondary Outcomes (7)

  • Chage in Hematocrit level

    Hematocrit levels will be measured at 24, 48 and 72 hours postsurgery

  • Drainage quantification

    Drainage quantification will be registered at 24 and 48 hours postsurgery

  • Therapeutic effect on visual analog scale

    The third day postoperative

  • Change in Hemoglobin level

    Hemoglobin levels will be measured at 24, 48 and 72 hours postsurgery

  • Complications

    at 24, 48 and 72 hours, 7 days, 4 and 6 weeks.

  • +2 more secondary outcomes

Study Arms (2)

Oral Tranexamic Acid

ACTIVE COMPARATOR

Tranexamic acid will be administered orally three times (administering 2 tablets each time). In the case of tranexamic acid tablets are 650 mg each. The first administration will be two hours before the induction of anesthesia, the second 6 hours post-surgery and the third 12 hours after surgery. All by oral administration with a drink of water. The medicines will be administered with a volume of 40 ml of water. For the tranexamic acid a total dose of 3.9 grams (6 tablets) divided between the 3 administrations (1.3 grams each, ie 2 tablets of 650 mg) will be administered.

Drug: Oral Tranexamic Acid

Oral Aminocaproic Acid

EXPERIMENTAL

Aminocaproic acid will be administered orally three times (administering 2 tablets each time). In the case of aminocaproic acid tablets are 500 mg each. The first administration will be two hours before the induction of anesthesia, the second 6 hours post-surgery and the third 12 hours after surgery. All by oral administration with a drink of water. The medicines will be administered with a volume of 40 ml of water. For the aminocaproic acid, a total dose of 3 grams (6 tablets) divided between the 3 administrations (1 gram each, ie 2 tablets of 500 mg) will be administered.

Drug: Oral Aminocaproic Acid

Interventions

Patients undergoing total knee replacement who will receive three doses of tranexamic acid administered orally (1 prior to surgery and 2 subsequent to surgery).

Oral Tranexamic Acid

Masking Details
Prior to being included in the study, the patient will be mentioned the times when he will receive the medication as well as the dosage of administration (which is the same for each of the two medications). The patient will not know what medication is being administered to him / her. no time The pills will be given to you in a medicine cup without access to any information legend.

PARALLEL
Model Details: Two study groups will be generated, each consisting of 40 research subjects, randomly each recipient will receive 3 doses of one of the two study drugs (tranexamic acid or aminocaproic acid). The group to which the patient belongs will be assigned through a computer program, the patient will not know to which group he belongs or what medication he will receive. The patients will be extracted from the external traumatology clinic.
