Prolonged use of high-frequency jet ventilation for a pediatric patient
Insights
High-frequency jet ventilation (HFJV) effectively treated a pediatric patient with respiratory failure and barotrauma. Successful weaning involved decreasing HFJV rate and transitioning to conventional ventilation, not solely by reducing drive pressure.
Area of Science:
- Pediatric critical care medicine
- Respiratory physiology
Background:
- Postoperative respiratory failure can occur in children, sometimes with barotrauma.
- High-frequency jet ventilation (HFJV) is an advanced ventilatory support method.
Abstract:
A 10-yr-old boy who developed postoperative respiratory failure with evidence of significant barotrauma was treated with high-frequency jet ventilation (HFJV). HFJV reduced peak inflation pressure, enhanced oxygenation, and improved ventilation. The patient could not be weaned from HFJV by decreasing drive pressure. Instead, he was successfully weaned by decreasing the HFJV rate to 80 cycle/min and then switching to conventional intermittent mandatory ventilation at initially similar rate and pressure levels.
