Monitorización de la oximetría cerebral en el manejo de la hipoxemia severa asociada a la transposición de grandes arterias mediante atrioseptostomía con balón / Cerebral oximetry monitoring in the management of severe hypoxaemia associated with transposition of the great arteries with balloon atrial septostomy

La transposición de las grandes arterias (D-TGA) es una de las cardiopatías congénitas más comunes que requieren una intervención quirúrgica en la etapa neonatal. En neonatos muy afectados por una D-TGA, la hipoxemia, la acidemia y la insuficiencia cardiaca congestiva secundaria se mejora a menudo con una atrioseptostomía con balón (ASB). Los métodos actuales empleados para evaluar el aporte y el consumo de oxígeno tisular, con frecuencia no son específicos. La espectroscopia cercana al infrarrojo o near infrared spectroscopy (NIRS) permite una medición continua no invasiva de la oxigenación tisular, reflejando el estado de la perfusión tisular en tiempo real. Debido a que se sabe poco sobre el efecto directo de la ASB en el cerebro neonatal y en la oxigenación cerebral de los mismos, nosotros medimos la eficacia de la ASB en 2 pacientes con D-TGA utilizando el NIRS antes y después de la ASB. Concluimos que la ASB mejora la saturación cerebral de oxígeno en neonatos con D-TGA

Transposition of the great arteries (D-TGA) is one of the most common congenital heart diseases requiring neonatal surgical intervention. In the desperately ill neonate with TGA and the resultant hypoxaemia, acidemia, and congestive heart failure, improvement is often obtained with balloon atrial septostomy (BAS). Current methods employed to evaluate oxygen delivery and tissue consumption are frequently nonspecific. Near infrared spectroscopy (NIRS) allows a continuous non-invasive measurement of tissue oxygenation which reflects perfusion status in real time. Because little is known about the direct effect of BAS on the neonatal brain and on cerebral oxygenation, we measured the effectiveness of BAS in two patients with D-TGA using NIRS before and after BAS. We concluded BAS improves cerebral oxygen saturation in neonates with D-TGA
