Abstract
High frequency jet ventilation (HFJV) has been used successfully for extracorporeal shock-wave lithotripsy (ESWL) to diminish renal stone movement during general anesthesia and to decrease the number of shocks delivered inadvertently to healthy tissue (1). Although usually uneventful, we present here eight cases out of 407 in which HFJV failed to ventilate patients undergoing ESWL, which necessitated the use of conventional mechanical ventilation (CMV).
