Infant with Congenital Diaphragmatic Hernia Clinical Pathway, Pre and Post-operative Care — Inpatient and ICU

Universal Care for Infants with CDH Before Surgical Repair: Mechanical Ventilation

Goals

  • Maintain adequate gas exchange with lowest pressures and tidal volumes
  • Stable respiratory settings without need for ventilator adjustments in 24-48 hrs prior to repair, FiO2 < 50%
  • To titrate ventilator settings, use goal pre-ductal oxygen saturation > 85% and FiO2 rather than PaO2
CDH Characteristic Initial Ventilatory Strategy Initial Targets
Liver Down
Mild Right
Synchronized Intermittent Mandatory Ventilation Pressure Control (SIMV-PC) PIP ≤ 25 cm H20
PEEP ≤ 5 cm H20
  • Consider:
    • Lower PEEP depending on lung inflation
    • Higher PEEP transiently for significant atelectasis
TV 4-6 ml/kg
Liver Up
Severe Right
Persistent hypercarbia despite maximal CMV settings
High Frequency Oscillatory Ventilation (HFOV) MAP 11-13 based on chest X-ray inflation, expansion
Obtain chest X-ray 1-2 hrs after MAP changes
Hz 6-8
Amp Adjust amplitude based on wiggle
