RESUMO

Abstract Tranexamic acid (TXA) significantly reduces blood loss in a wide range of surgical procedures and improves survival rates in obstetric and trauma patients with severe bleeding. Although it mainly acts as a fibrinolysis inhibitor, it also has an anti-inflammatory effect, and may help attenuate the systemic inflammatory response syndrome found in some cardiac surgery patients. However, the administration of high doses of TXA has been associated with seizures and other adverse effects that increase the cost of care, and the administration of TXA to reduce perioperative bleeding needs to be standardized. Tranexamic acid is generally well tolerated, and most adverse reactions are considered mild or moderate. Severe events are rare in clinical trials, and literature reviews have shown tranexamic acid to be safe in several different surgical procedures. However, after many years of experience with TXA in various fields, such as orthopedic surgery, clinicians are now querying whether the dosage, route and interval of administration currently used and the methods used to control and analyze the antifibrinolytic mechanism of TXA are really optimal. These issues need to be evaluated and reviewed using the latest evidence to improve the safety and effectiveness of TXA in treating intracranial hemorrhage and bleeding in procedures such as liver transplantation, and cardiac, trauma and obstetric surgery.

RESUMO

Se presenta el caso clínico de una adolescente ecuatoriana de 17 años de edad, blanca, quien nació producto de un embarazo normal y parto eutócico. Posterior al nacimiento se le realizó estudio genético que mostró la presencia de un cariotipo X0, por lo cual se le diagnosticó síndrome de Turner. A los 3 años fue operada de hipoplasia del arco aórtico con una evolución favorable. En la actualidad la paciente tiene baja talla con orejas de baja implantación, así como implantación alta del cabello en la nuca, tórax plano en forma de escudo, escaso bello pubiano y ausencia de menstruación
