Unchanged and new recommendations regarding surgical readiness criteria for CDH94–96

Unchanged recommendationsStrength of consensusLevel of evidence
9.1 The following criteria should be met prior to surgery: urine output >1 mL/kg/hour, FiO2 <0.5, preductal oxygen saturation between 85% and 95%, normal mean arterial pressure for gestational age, lactate <3 mmol/L and estimated pulmonary artery pressures less than systemic.4B-NR
9.2 Surgery should be reconsidered if a patient fails to meet surgical readiness criteria after 2 weeks.4C-LD
New recommendationStrength of consensusLevel of evidence
9.3 In patients who have achieved physiological stability, there is no benefit in delaying operative repair.4C-LD
  • CDH, congenital diaphragmatic hernia; FiO2, fractional inspired oxygen; LD, limited data; NR, non-randomised.
