Abstract

In an effort to decrease morbidity and mortality, newer modes of mechanical ventilation have been introduced into the critical care arena. One such technique, high frequency oscillatory ventilation (HFOV) relies on respiratory rates greater than 150 b·min-1, small tidal volumes, and the maintenance of a constant distending pressure thereby limiting peak inflating pressure and potentially the incidence of barotrauma. Despite the frequent application of this technique in the ICU setting, there is limited information concerning its intraoperative use. We present three infants who represent the perioperative applications of HFOV: (i) elective preoperative use to minimize lung movement and interference with surgical exposure during thoracotomy and PDA ligation; (ii) intraoperative application when progressive alterations in respiratory compliance led to ineffective intraoperative ventilation/oxygenation; and (iii) anaesthetic care for a neonate already receiving HFOV. The techniques of HFOV and previous reports of perioperative use are reviewed.
