High Frequency Oscillatory Ventilation Versus High Frequency Jet Ventilation for Congenital Diaphragmatic Hernia

Not Applicable

Recruiting

• Conditions: Congenital Diaphragmatic Hernia

• Registration Number: NCT04774848
• Lead Sponsor: University of Utah

Brief Summary

The purpose of this study is to conduct a prospective study of all congenital diaphragmatic hernia (CDH) neonates managed at the University of Utah newborn intensive care unit (NICU) and Primary Children's Hospital NICU that required mechanical ventilation at birth. As both high frequency jet ventilation (HFJV) and high frequency oscillatory ventilation (HFOV) are standard approaches to ventilatory support of all neonates including CDH, CDH infants will be randomized at the time of birth or admission to either HFJV or HFOV as initial ventilator mode, stratified by position of the liver in the abdomen or thorax (if known) by 24 hours of age. Measures of oxygenation, ventilation and hemodynamics of the CDH cohort managed on HFOV compared to those on HFJV.

Study & Design

• Study Type: INTERVENTIONAL
• Study Design: PARALLEL

Primary Outcome Measures

Name	Time	Method
Oxygenation Index (OI) at 24 hours of age	24 hours of age	The OI will be measured at 24 hours of age using a standard of care arterial blood gas and oxygen settings. These measurements will then be compared between the stratified groups

Secondary Outcome Measures

Name	Time	Method
PF ratio (PaO2/FiO2) measurements	up to one week	These measurements will be determined at multiple time points for the first week of life. These measurements will be compared between groups.
PF-PCO2 (PaO2/FiO2-PaCO2) measurements	up to one week	These measurements will be determined at multiple time points for the first week of life. These measurements will be compared between groups.
Number of babies who received inhaled nitric oxide (iNO)	up to one week	the number of babies who received treatment of iNO will be compared amongst the different groups
PaCO2 measurements	up to one week	These measurements will be determined at multiple time points for the first week of life. These measurements will be compared between groups.
