THE improved viability of low- and very-low-birth-weight infants increases the need for providing safe and adequate anesthesia for those smaller and sicker infants. Premature infants have structurally and functionally immature lungs that predispose to hypoxia. As in critically ill neonates, low lung volumes and poor compliance increase intrapulmonary shunt and ventilation/perfusion mismatch. Those infants are very susceptible to oxygen toxicity and barotrauma. Therefore, anesthetic goals include minimizing the inspired oxygen concentration and the peak inspiratory pressures while maintaining adequate oxygenation and ventilation. 1High-frequency oscillatory ventilation (HFOV) is a widely used lung-protective strategy in neonatal and pediatric acute lung injury. 2The beneficial effects of HFOV on oxygenation and ventilation are well known, but only a few reports describe the use of this technique for intraoperative ca...
