PSYCHIATRIC RESPONSE PATTERN TO CONVENTIONAL VENTILATION COMPARED WITH HIGH FREQUENCY JET VENTILATION

To identify tracheobronchial abnormalities associated with assisted ventilation, 40 infants with respiratory distress syndrome randomized to receive either short-term (48 hours) conventional or high-frequency jet ventilation were studied. Flexible fiberoptic bronchoscopy (n = 13) was performed and/or clinical and radiographic assessments were used to evaluate for laryngeal, tracheal, and bronchial lesions. There was no bronchoscopic evidence of necrotizing tracheobronchitis after either high-frequency jet ventilation (n = 8) or conventional ventilation (n = 5). Laryngotracheomalacia and nodular vocal cords were the most common abnormalities noted, and they occurred with equal frequency in both groups. Study infants who were not bronchoscoped had no clinical or radiographic evidence of tracheal or mainstem bronchial obstruction. One patient did have microscopic evidence of necrotizing tracheobronchitis at autopsy, however. It is concluded that short-term treatment of respiratory distress syndrome with high-frequency jet ventilation may be performed without undue risk of tracheobronchial injury.

Patent Ductus

Background: Patent ductus arteriosus (PDA) treatment is typically pharmacologic, but if unsuccessful, surgical ligation is commonly performed. High-frequency jet ventilation (HFJV) is used at the University of Iowa Stead Family Children’s Hospital for extremely low birth weight infants. Historically, neonates requiring PDA ligation were temporarily transferred to conventional ventilation (CV) prior to surgery. Objective: The objective of this study was to determine whether conversion was necessary. Methods: This retrospective cohort analysis examined outcomes following PDA ligation from 2014 to 2016 at the University of Iowa’s Stead Family Children’s Hospital. Infants who were transferred to CV prior to surgery and returned to HFJV postprocedure are referred to as the CV cohort. The HFJV cohort infants remained on HFJV throughout. Results: We found no significant increases in morbidity or mortality with the use of intraoperative HFJV and potentially show some benefit through greater reduction in serum CO2. Conclusions: Mode of ventilation during PDA ligation does not affect surgical morbidity or mortality or short-term clinical outcomes. Conversion to CV from HFJV is not necessary.
