Resumen
LOPEZ-GARCIA, RA y PENA-OLVERA, S.. Tranexamic acid neurotoxicity in pediatric renal transplantation: case report. Anest. Méx. [online]. 2019, vol.31, n.2, pp.74-83. ISSN 2448-8771.
Pediatric kidney transplantation has become the primary method of treating in children with final stage kidney disease, with 90% survival rate. Commonly, this surgery is not associated with bleeding disorders intraoperative and when this occurs; It increases postoperative morbidity and mortality. Clinical case: An Eight year old girl with chronic kidney disease stage V, due to tobulointerstitial disease, was scheduled for kidney transplantatio from a related living donor. During the surgical procedure she presented an injury in the kidney vein and renal artery, this caused an increase in circulating blood volume during severe hemorrhage; it required a masive transfusión protocol with blood products and hemodynamic stabilization with norepinephrine. Tranexamic acid was administered under a hyperfibrinolysis condition, verified by thromboelatografhy. It resulted in a reduced postoperative bleeding and the need for more blood products, however, there were side effects with seizures, attributed to an acute ischemic stroke reported by a tomography.
Discussion.
Tranexamic acid neurotoxicity is low and multifactorial, mainly due to the presence of kidney disease; possibly becouse it is the key route for elimination. This increased its serum concentrations and gaba aminobutyric receptor antagonism associated with vasospasm that triggerseda seizure event.
Conclusión.
Tranexamic acid has an important hemostatic benefit in patients at high risk of hemorrhage, however, the posible adverse effects on the central nervous system have been poorly studied and therefore were not clearly defined in pediatric patients with kidney disease in the stage.
