Empleo de ventilación de alta frecuencia oscilatoria intraoperatoria en neonatos con hipoplasia pulmonar / Use of intraoperative high frequency oscillatory ventilation in neonates with pulmonary hypoplasia

La ventilación de alta frecuencia oscilatoria (VAFO) es una modalidad ventilatoria ampliamente utilizada en las unidades de cuidados intensivos neonatales. Su principal indicación es la patología pulmonar restrictiva con dificultad en alcanzar un adecuado intercambio gaseoso en ventilación mecánica convencional (VMC), siendo necesaria una elevada asistencia que puede suponer riesgo de barotrauma y volutrauma en un pulmón inmaduro. Las publicaciones sobre el empleo de VAFO en quirófano son limitadas y se reducen principalmente a su uso durante la reparación de hernia diafragmática congénita. La limitada experiencia de este método ventilatorio en quirófano puede suponer una barrera para el anestesiólogo. Sin embargo, es importante recordar los beneficios que esta modalidad ventilatoria aporta como estrategia de protección pulmonar. Se presentan dos casos de hipoplasia pulmonar neonatal de diferente etiología, en los que se empleó VAFO en el intraoperatorio con buenos resultados en la oxigenación y ventilación.(AU)

High-frequency oscillatory ventilation (HFOV) is a ventilatory modality widely used in neonatal intensive care units. Its main indication is restrictive lung pathology with difficult gas exchange using conventional mechanical ventilation (CMV). Patients receiving CMV require high intensity care, and immature lungs can be at risk for barotrauma and volutrauma. The few studies that have explored the use of HFOV in the operating room are mainly limited to HFVO during congenital diaphragmatic hernia repair. Limited experience of this ventilatory method in the operating room may be a disadvantage for the anesthesiologist. However, it is important to remember the benefits of this technique as a lung protection strategy. We report two cases of neonatal pulmonary hypoplasia of different etiology in which good oxygenation and ventilation was achieved with intraoperative HFOV.(AU)
