Tranexamic Acid-Induced Seizure After Cardiopulmonary Bypass: A Case Report

Tranexamic acid (TXA) is a risk factor for perioperative seizures following cardiac surgery. However, its clinical diagnosis is difficult because these signs are masked by anesthetics and muscle relaxants. In this case, a direct temporal association between high-dose TXA administration and seizure onset was confirmed using intraoperative electroencephalography (EEG) and central venous oxygen saturation (ScvO2) changes.This case demonstrates that seizures can be triggered immediately after high-dose TXA administration and highlights the importance of integrated assessment of continuous EEG and ScvO2 for the early detection of subclinical seizures. This allows for prompt intervention and may lead to better neurological outcomes.
