Unchanged and new recommendations regarding surgical readiness criteria for CDH94–96
| Unchanged recommendations | Strength of consensus | Level 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. | 4 | B-NR |
| 9.2 Surgery should be reconsidered if a patient fails to meet surgical readiness criteria after 2 weeks. | 4 | C-LD |
| New recommendation | Strength of consensus | Level of evidence |
| 9.3 In patients who have achieved physiological stability, there is no benefit in delaying operative repair. | 4 | C-LD |
CDH, congenital diaphragmatic hernia; FiO2, fractional inspired oxygen; LD, limited data; NR, non-randomised.
