Tranexamic Acid and Convulsive Seizures After Off-pump Coronary Artery Bypass Surgery: the Role of Renal Insufficiency
There is evidence that, in adult cardiac surgical patients undergoing on-pump procedures, tranexamic acid (TXA) dose-dependently increases the risk of convulsive seizure (CS). We aimed to investigate whether a single TXA bolus of 1 g influences the risk of CS in patients who were operated on without the use of cardiopulmonary bypass. In 2249 propensity-score-matched pairs who underwent off-pump coronary artery bypass grafting with or without TXA administration, the risk of CS was 0.5% and 0.3% in the TXA and non-TXA groups, respectively (P = 0.36). In the subgroups of patients with estimated glomerular filtration rates <30, 30–60 and >60 ml/min/1.73 m2, the risk of CS in the TXA group was 2.8%, 1.2% and 0.4%, respectively (P = 0.002), and in the non-TXA group 0.0%, 0.0% and 0.3%, respectively (P = 0.36). The risk of stroke, in-hospital mortality and 30-day mortality did not differ significantly between study groups (P-value >0.05). Our data indicate that in patients undergoing off-pump coronary artery bypass grafting, a single TXA bolus of 1 g generally does not increase the risk of CS. However, the presence and extent of renal insufficiency have a very significant impact on the incidence of CS even after single-dose TXA.
To assess the efficacy of this cell therapy, retrospective comparative study was conducted between the bones treated with BMC and PRP and the bones treated without BMC and PRP during DO in patients with achondroplasia (ACH) and hypochondroplasia (HCH).
Bivalirudin, a direct thrombin inhibitor with a fast onset of action and short half-life, is often referred to as an alternative anticoagulant to a heparin/protamine regimen.
