Abstract
Background and aim: Intraoperative use of a single bolus dose of tranexamic acid may not be sufficient to prevent bleeding in the early postoperative period. The present study was carried out to compare the effect of two dose regimens of tranexamic acid in reducing perioperative blood loss and the amount of allogeneic blood transfusion in transurethral resection of prostate.
Design: prospective, double-blinded and controlled study.
Setting: Ain Shams University Hospital,
Patients and Methods: 50 patients electively posted for transurethral resection of prostate were randomly assigned to receive a single bolus dose of tranexamic acid (10 mg/kg) (group A), a bolus dose of tranexamic acid (10 mg/kg) followed by infusion (1 mg/kg/h) till 4 h postoperatively (group B).
Measurements: Total intraoperative blood loss, amount of allogeneic blood transfusion, postoperative drain collections, and hemoglobin and hematocrit levels were recorded at different time intervals. Data obtained after comparing two groups were analyzed using the statistical package for social sciences.
Results: There was no statistically significant difference among patients in both groups regarding intraoperative blood loss and postoperative blood loss at 6 hrs and 48 hrs postoperatively. However the post-operative blood loss at 24 hrs was significantly higher among patients in group A than patients in group B (P-value= 0.014) .
Conclusion: Tranexamic acid causes more effective reduction in post-operative blood loss when used as a bolus followed by an infusion continued in the postoperative period in comparison to its use as a single intravenous bolus in transurethral resection of prostate.
