Clinical Trial Summary
The investigators aimed to compare two doses of intravenous (IV) tranexamic acid (TXA) with a
combined single dose of topical and IV TXA on haemoglobin decline 24 hours after total joint
arthroplasties.
The investigators conducted randomized, double-blind trial. The participants were randomized
to either intrvenous group receiving 2 doses of 1 gram TXA in intravenous route 3 hours
apart, or a combined application group receiving the first 1 gram IV and the topical dose was
1.5 gram after reduction of the fascia.
Description:
The investigators provided the pre-anaesthetic consultation. They carried out a rigorous
clinical examination, a balancing of the defects and an adjustment of the therapies. The
patients' written and informed consent was obtained. All patients had a preoperative blood
count, blood grouping, renal assessment with dosage of uremia and creatinine. The
investigators calculated the tolerable losses (mL). Randomization and allocation were carried
out at this stage by an anesthesiologist other than the one managing the patient
perioperatively.
On arrival in the operating room, the investigators set up the following systematic
monitoring: electrocardioscope, pulse oximetry, gas analyzer, monitoring of capnia and
curarization in the event of general anesthesia, non-invasive blood pressure. Two peripheral
venous approaches were put in place. All patients received antibiotic prophylaxis with 2 g of
Cefazolin and in case of allergy 900 mg of Dalacin. The anesthetic protocol was standardized.
The choice between general or locoregional anesthesia was left to the discretion of the
anesthesiologist treating the patient. For each patient, the investigators specified: The
surgical approach, the type of prosthesis (cemented or not), the intraoperative posture, the
duration of the procedure and of the anesthesia. During intraoperative monitoring, any
hypotension with a decrease in mean arterial pressure of 20% of the baseline value for a
period of more than 3 minutes or other complications were mentioned. The estimated bleeding
(contents of the suction jar, number of drapes and compresses soaked in blood) with
determination of the percentage of total losses intraoperatively as well as the results of
the intraoperative blood count (if deemed necessary) were also specified. Transfusion of
labile blood products was managed according to the patient's terrain, the degree of anemia,
the speed of onset of the anemia and his hemodynamic tolerance. The analgesic protocol was
also standardized.
