Hypoxic Respiratory Failure in Term & Near Term Infants: Scottish Perinatal Network Neonatal Guideline
What's new / Latest updates
22/04/2026 Summary of changes for version 2: In stages 1, 2, and 3: Consider discontinuing iNO if no response; Dobutamine can be considered as an alternative to adrenaline; Avoid using dopamine; Aim for Mean Blood Pressure >45 mmHg & Pulse Pressure >20 mmHg. In stage 3: Consider targeted use of additional cardiotropes in experienced centres.
This guideline has been developed for medical staff caring for term and near term (>34wk) infants throughout Scotland.
Respiratory failure is a failure of the respiratory system to oxygenate (hypoxaemia) or to clear CO2 (hypercapnia). Invasively ventilated babies with one or more of:
- Oxygen requirement ≥ 60% (to achieve preductal saturation of 94% and above)
- pCO2 ≥ 8kPa
- H+ ≥ 60 (pH <7.22)
should be considered at risk of hypoxic respiratory failure (HRF) and persistent pulmonary hypertension of the newborn (PPHN). These babies require advanced management strategies and early discussion with a specialist centre for consideration of transfer.
The aim is to provide standardised care for these babies and provide a pathway to aid management and referral to a specialist centre if required for ongoing care. This guideline will not cover the management of babies born with congenital diaphragmatic hernia.
