Abstract

Background: Mortality and morbidity associated with intracerebral hemorrhage is still high. Up to now, there are no evidence-based effective treatments for acute ICH. This study is to assess the effect of tranexamic acid (TXA) on hematoma growth of patients with spontaneous ICH compared to a placebo.

Methods: We performed a single-blinded, randomised placebo-controlled trial of TXA (intravenous 1g bolus, followed by infusion TXA 1 g/hour for 8 hours) in acute (< 8 hours) primary ICH. Strict blood pressure control (target SBP 140-160 mmHg). A repeat Computed Tomography brain was done after 24 hours to reassess hematoma growth. The primary objective is to test the effect of TXA on hematoma growth. Other objective was to test the feasibility, tolerability, and adverse events of TXA in primary ICH.

Results: Statistical analysis showed significant hematoma growth in control group after 24 hours compared to baseline (14.3300 vs 17.9940, P = 0.001) whereas the treatment group there is no significant hematoma size expansion between baseline and after 24 hours (P = 0.313).

Conclusions: This study showed a significant hematoma volume expansion in the control group compared to the treatment group.

Keywords: antifibrinolytic agents; hypertension; non-traumatic intracerebral bleed; primary hypertensive hemorrhage; tranexamic acid.
